Communication Bus

*ALL SIGNAL FOR CONTROL AND USER INTERFACE HAVE DOUBLE ISOLATION

The module is built around the following sub-converters
· AC to DC at input · DC to DC at input · DC to AC at output
The energy can flow either from the AC source or the DC source under the control of the local DSP controller. Thanks to internal energy buffering, the output sine wave is constant and disturbance free regardless of the active source.
The BOOST functionality multiples the nominal current to 2.4 x In times for a period of 20ms (max) in the event of down stream failures. The upstream breakers does not have to be oversized to prevent tripping. The overload capacity is 150% for 15 seconds.
The TSI works according to True Redundant Structure (TRS) that features decentralized and independent logic, redundant communication bus and three internal levels of disconnection to isolate a module after internal failure.
The functionality is included in every UPS module. Running them in parallel provides a modular system with, no single point of failure, always conditioned output, high system efficiency and 0ms source transfer time.

SNMP V1 & SNMP V3 Configuration
12. SNMP V1 & SNMP V3 Configuration
SNMP is now available on T4S supervisor and on Catena display. SNMPv1 is available on T4S supervisor. The MIB implemented on T4S SNMP agent is the standard USP MIB defined by RFC1628. Catena display now includes a SNMPv1 to SNMPv3 proxy. The main difference between SNMPv1 and SNMPv3 is the addition of secured connection in SNMPv3.
12.1 SNMPv1 Configuration
For SNMPv1 agent configuration, go to Parameters > Monitoring > Network.
See T4S network section for ETH port configuration:
· IP address. · Subnet mask. · Gateway.
See T4S SNMP section for SNMP agent configuration:
· Trap receivers IP addresses. Up to 5 trap receivers can be configured. · Note that ports 161 and 162 (for traps) are used. Not configurable.
12.2 SNMPv1 MIB (RFC1628)
The MIB is the standard UPS MIB defined by RFC1628. Meaning of "input lines": input lines are AC input groups as existing in T4S web interface. One tri-phase system will have 3 input lines, one for each phase. Meaning of "output lines": output lines are AC output groups as existing in T4S web interface. The following features of UPS MIB are not implemented in T4S:
· Writable entries. The current MIB is read-only. Entries can only be edited through the web server. For this reason, the upsConfig section is also read-only.
· Bypass values. As T4S doesn't include the monitoring of bypass devices, bypass measurements are not available in the MIB. It is however possible to know when the system switched to MBP by reading ups Output Source value (OID .1.3.6.1.2.1.33.1.4.1).
· Well known test. Only standard battery test is available. No other test is implemented in T4S at current state. Any feature defined in RFC1628 that is not in the previous list is available.
12.3 SNMPv3 Configuration
For SNMPv3, you need a Catena display. The Catena display can be used as SNMPv1 to SNMPv3 proxy. The configuration of Catena display is managed by T4S supervisor. In T4S web interface, go to Parameters > Monitoring > Network.
66 - Flexa 200 - UPS Systems - User Manual - v2.0

SNMP V1 & SNMP V3 Configuration
See Catena network section:
Set IP address, subnet mask, and gateway for local network. Set "bridge enable" option. By default, both ETH ports of Catena are in the same LAN. If the bridge is disabled, then each port is on an independent LAN. If bridge is disabled, set IP address, subnet mask, and gateway for external network. If bridge is disabled, the most outward ETH port is connected to the local network, and the most inward ETH port is connected to the external network. The T4S must be on the local network. Please not that SNMPv1 agent and T4S web server are have no security. For a secure connection, it is strongly recommended to use SNMPv3 interface only (T4S on local network and bridge disabled).
See Catena SNMP section:
SNMPv3 context can be configured.
SNMPv1 agent community can be configured. Not used for now since T4S agent community is not configurable (public by default).
Three users can be configured: · Read-only user. There is no authentication and no encryption. No other parameter than user name is required. · NoPriv user. This user is authenticated but there is no encryption. Authentication protocol (MD5 or SHA) must be selected. Authentication password must be configured. · Priv user. This user is authenticated and connection is encrypted. Authentication protocol (MD5 or SHA) must be selected. Authentication password must be configured. Encryption protocol (DES or AES) must be selected. Encryption key must be configured. · A user can be completely disabled by setting an empty user name.
Base OID's have to be configured for each user.
One trap received can be configured: · Trap received IP address. · Engine ID. · Security level. You can select if the trap will use both authentication and encryption, only authentication, or none. · Trap authentication password. Only required if authentication is enabled in security level option. · Trap authentication protocol (MD5 or SHA). Only required if authentication is enabled in security level option. · Trap encryption key. Only required if encryption is enabled in security level option. · Trap encryption protocol (DES or AES). Only required if encryption is enabled in security level option.

Annexe 1. Battery Management with Flexa Technology and T4S
1.1. Introduction
Battery is critical element in a UPS. Many manufacturer offer high performances of their electronic but sometimes forgot about providing an efficient and reliable battery management. Battery is fragile and needs to be treated accordingly in discharge and recharge conditions. The purpose of this document is to provide an overview of how TSI and Flexa manage the batteries, prevent their end of life and reduce possible occurrence of thermal runaway.
1.2. CE+T Battery Charging and Discharging Mode
The purpose of a charger is to "refill" the charge tank of the battery. There are many other features which enhance the convenience of the charger, or grant protection for the battery being charged. These built-in protection features is what fundamentally elongates the battery's life, or more correctly, prevents premature failure. TSI technology provide those features:
· Higher current levels reduce recharge times (assuming the battery can accept charge at high rates). · Voltage limits, current limits, and time out to reduce excessive gassing at end-of charge, and prevent dry-out. · Modified voltage and current limits as a function of temperature reduce gassing and electrode damage. · BOOST or Equalize mode to equalize battery blocs periodically CE+T Flexa and controller T4S battery operating mode are described below
1.2.1 MODE 1 BOOST
This mode need to be activated and configured according the battery data from the manufacturer A CCCV (constant current, constant voltage ) algorithm to provide a "quick an fast recharge. Ideally to recover 80% of the battery capacity in maximum 8 hours. This mode use a U voltage level associated to current limit protection
set
Figure 1. Typical recharge curve versus time for voltage and current.
75 - Flexa 200 - UPS Systems - User Manual - v2.0

MODE 1 algorithm can be trigger based on the following parameter: · Trig Start Voltage : Will activate MODE 1 when battery voltage goes below pre-set level · Trig Start Current : will activate MODE 1 when battery current goes above the pre-set value · Trig Start Period : Will activate MODE 1 periodically base on pre-set value · Manual Start : Will activate MODE 1 manually through the GUI menu
In mode 1 the temperature compensation is disabled. MODE 1 algorithm can be stopped based on the following parameter :
· Trig Stop Current: Will stop MODE 1 when battery voltage goes below pre-set level and MODE 1 for minimum 5 minutes (to avoid successive Start and Stop)
· Trig Stop Duration: 1H to 48H will stop MODE 1 (always active) will stop the MODE1 after the duration.
Note: If MODE1 stop based on "duration" before the "Stop current" reached an alarm will be generated as the battery need to be checked.
· Trig Start Period: Will activate MODE 1 periodically base on pre-set value · An alarm appear in the system: MODE 1 will be disabled in case of alarm presence · Manual stop: will STOP MODE 1 manually through the GUI menu
1.2.2 MODE 2 FLOAT:
This is the normal operating mode for maintaining the battery in charge. This mode is enabled by default
The MODE 2, charging voltage is adapted (provided it is enabled in the configuration) according the temperature. Using the charging curve below. T° bas-low and T° haut-high are adjustable
Note: If the temperature probe is disconnected or defective the voltage will come back to the value at 20°C. An alarm T° sensor fail" will be generated.
76 - Flexa 200 - UPS Systems - User Manual - v2.0

1.2.3 MODE 3 Discharge
Discharge mode is active when energy flow is taken from the battery to the DC/AC converter (inverter) of each module. In this mode the T4S monitoring sent a voltage and current value to the Flexa module. This help in case of one module has AC input failure to take power from DC and is feed through the other module to avoid discharging the battery and assure the continuity of supply for the AC load. Following alarms and time out available:
· Ubat < Ufloat · BAT cell V low · BAT end of autonomy · BAT discharge time out (Battery in discharge for more than xx minutes) · V BAT stop: Flexa will stop operating to prevent deep discharge
Note: During discharge, T4S will record battery discharge value
1.2.4 MODE 4 BATTERY TEST
Battery test is a helpful function to get reliable information on the battery conditions and capacity. It is recommended to perform periodic test of the battery but more important to perform those test in the same conditions in order to obtain comparative data over the years of the battery lifetime. Starting BATTERY TEST conditions:
· Manual · Trig Start Period: Specify the day of the week to perform the periodic test and the number of weeks between 2
tests.
Note: Periodic test will start only if no discharge during last 96 hrs. to guarantee the same start conditions for every test.
Stopping BATTERY TEST conditions: · Trig Stop Duration : always active. Define the maximum time duration of a test · Trig Stop Voltage : stop the test when battery voltage reaches the pre-set value · An alarm appears in the system: AC IN failure Module failure V BAT too low System Overload · Manually through the GUI menu
Note: During any test or battery discharge the following data will be recorded.

Annexe 2. Manual Bypass (MBP)

The purpose of this document is to provide guidelines for customers to implement, assemble, wire and test external manual by-passes using CE+T Flexa modular UPS' with T4S monitoring units.
The CE+T delivered cabinets equipped with manual by pass are not concerned by this document.

2.1. Introduction

The purpose of the Manual Bypass also named "service by pass" is to provide the capability to completely by-pass the modular UPS Flexa system and SBP in order:
· To perform service maintenance to the equipment · To externally by-pass the UPS installation and allow the removal of the equipment

2.2. Principle of Operation

The manual by-pass (MBP) is a "make before break" Bypass manual switch.

The MBP can be in 3 position mode:

OFF or NORMAL:

The MBP is not engaged (OFF) and the USP normally feeds the critical load.

INTERIM or TRANSFER:

The MBP is in a temporary interim position where the AC load is supplied through the manual by-pass. The Flexa UPS is in start up mode and not yet connected to the AC output.

ON or BY PASS:

The MBP is engaged, the AC input feeds the AC load, the UPS modules are OFF. Disconnect DC source to turn OFF the system completely. (Note: Flexa Module auxiliary power supply and monitoring are still power up by DC source once MBP is engaged)

Warning: If MBP is engaged, the neutral connection is not isolated and not voltage free.

Block wiring of the MBP

79 - Flexa 200 - UPS Systems - User Manual - v2.0

NORMAL mode or OFF: S1 is open, S2 and S3 are closed INTERIM or TRANSFER: S1 is closed
S2 and S3 can be in position OPEN or CLOSED depending where you are in the manual by pass procedure
Note: This position is only temporary. It is used to allow the modules to start up and synchronize with the AC input. The user should not keep the Bypass in the INTERIM position.
BY-PASS mode or ON: S1 is closed. S2 and S3 are open.
2.3. Presentation
The Manual By-pass can be provided with 2 executions: 1. Rotary Switch for Flexa 60 kVA and Flexa 160 kVA
2. Two (2 )power switches external to the Flexa cabinet for power above 160 kVA
Please refer to the Flexa installation manual for more specific procedures.
80 - Flexa 200 - UPS Systems - User Manual - v2.0

2.4. MBP Wiring
Both solutions (rotary by-pass or separate switches) need to have auxiliary contacts that need to be wired to the monitoring unit as described below and as shown on the drawing present in annexe
Aux 3 (from the by pass switch) : Provides an input to the controller indicating that the MBP is engaged Aux 1 (From AC input switch) and Aux 2 (from the by pass SWITCH):
· Switch OFF the Flexa modules once the MBP is engaged. · Allow the Flexa modules to switch ON when the MBP placed in the INTERIM position.
Note: The parameter "Out voltage consign" set by default to 230 Vac shall be adjusted according nominal AC input voltage. This will limit the inrush current when operating on Smart By pass and Manual By pass.
81 - Flexa 200 - UPS Systems - User Manual - v2.0

2.5. MBP Procedure
2.5.1 Normal to By-Pass
Internal MBP 1. Turn MBP switch from position NORMAL to INTERIM 2. Turn the MBP switch from INTERIM to position BYPASS 3. Switch off DC input from the battery to the Flexa Cabinet

External MBP 1. Turn switch S1 to position 2

Annexe 3. Smart By-Pass (SBP)

The purpose of this document is to provide guidelines for customers to access the Smart By Pass using CE+T Flexa modular UPS' with T4S monitoring units.

Note: SBP should be installed and operated only in Flexa UPS System.

Caution: If Flexa and SBP has two different input source, it is mandatory to disable the Boost function. Refer "Triac enabled" parameter at section "Other", page 58.

3.1. Introduction

The purpose of the Smart By-Pass is to provide the capability to

AC OUT

completely by-pass the modular UPS Flexa system in order:

· SBP will transfer the Load to Bypass without interruption.

SBP SYNC

· To perform service maintenance to the equipment.

AC IN

· To externally by-pass the UPS installation and allow the removal of the equipment.

MBP MODE

UPS MODE

ALARM OVERLOAD ECOMODE

3.2. Principle of Operation

The SBP operates in two modes:

1. UPS Mode

The priority is given to the Flexa module and the SBP is in standby.

In the event of a disturbance of the Flexa and/or battery end of discharge, the system will provide unconditioned power to the load by returning to ECO mode feeding the load through SBP in AC to AC.

2. ECO Mode

The priority is given to the SBP while Flexa are in support mode.

If the SBP AC input voltage is out of range min or max the Flexa will take over the load.

In the event of a power disturbance, the system will provide conditioned power to the load by returning to UPS mode feeding the load through Flexa in AC to AC or DC/AC. When operating in ECO mode Flexa fan speed shall be reduced to its minimum.

Block diagram - SBP with Flexa and MBP

Note: The parameter "Out voltage consign" set by default to 230 Vac shall be adjusted according nominal AC input voltage. This will limit the inrush current when operating on Smart By pass and Manual By pass.

In any of the operating mode: "ECO mode" or "UPS Mode", the AC output will always be synchronized on the SBP AC input. Only Flexa module without BOOST will be used in ECO mode. If module with BOOST are

83 - Flexa 200 - UPS Systems - User Manual - v2.0

used the BOOST shall be disabled. Warning: If SBP is engaged, the neutral connection is not isolated and not voltage free.
System will stay in ECO mode provided that: · The AC input voltage range are within the configured limits min and max Vac in of the SBP; · Below and above those limits the UPS will go in Flexa mode (either AC to AC or DC to AC, depending on AC input connected to Flexa module). The transfer shall not suffer any interruption of the load and shall respect classification 3 of IEC 62040-3 (see curve here below);
· Vac min and Vac max will be adjustable between: 195 Vac to 210 Vac for Vac min transfer;
Note: Vac min too low could lead to higher transfer time. If 195 Vac doesn't allow to guarantee classification 3 of IEC 62040-3, the minimal acceptable value must be identified.
250Vac to 265Vac for Vac max transfer. · Hysteresis will be constant and fixed to the most appropriate value according the measurements device of the
SBP/Flexa and to prevent any intermittent transfer ECO to Flexa and vice versa; · One alarm shall be generated if the output power through the SBP in ECO mode exceed the Flexa installed
power. In this eventuality, the system will be blocked in ECO mode and prevent any transfer; · The return from Flexa mode to ECO will be automatic once the SBP AC input is within the range. A adjustable
timer 1 to 90 sec will delay the return to ECO mode except if end of autonomy of the battery is reached. · In order to detect a back feed on SBP input in some cases, ECO mode should be disabled when under a
percentage of the max output power of the system (20% of the Flexa installed power); · CE+T requires electrical schematics of the system deployed in order to facilitate the integration, I/O and alarm
mapping; · The monitoring will generate an URGENT alarm in case output power exceed the maximum power of the
available Flexa module. Any transfer from ECO mode to UPS mode will be blocked if the AC load power exceed the power available from Flexa module. "Saturation" and "OVL" alarms active;
84 - Flexa 200 - UPS Systems - User Manual - v2.0

· CE+T will activate function to enable the eco-mode via a parameter (configured via T4S);
· It is asked to be able to configure the delay to return to eco-mode between 1 sec to 90sec (default value 90 sec). We would like to fix this time a little above 90s, because of the typical time constants of external electrical devices;
· If the Flexa & SBP are on the same AC source and the walk in mode is implemented. The walk in mode shall be used before returning to ECO mode. This means from Flexa UPS operating on battery a smooth transfer to AC input and when completed the SBP will switch to ECO mode. If the walk-in mode duration is longer than the ecomode delay (see above paragraph), the walk-in mode duration is used instead of the eco-mode delay. No walk-in mode is implemented when Flexa and SBP are not on the same AC source.

Def. Map

Description

Output V is under a threshold (due to an overload) for too much time
Output V setpoint was modified and is being converged on

Flexa module is supplying too much power to the load compared to the other modules
Flexa module is not supplying enough power to the load compared to the other modules

Flexa is supporting either the SBP or MBP output, i.e. it does not supply any current, but in case of a voltage drop will try to keep the voltage at an acceptable level
An individual driver is sending an alarm but global drivers monitoring signals are OK

Hardware driver not ready signal received Hardware driver fault signal received Too many consecutive AC out over-current trips Software detected IGBT fault Output V at Pi/2 (sine max) is out of expected range with open relay Output V at -Pi/2 (sine min) is out of expected range with open relay Output Off from bus request Output stopped because of backfeed from this module or another one Too many attempts to start output over some time Output fuse open or enventualy output connector not connected SBP could not close when needed
SBP could not open when needed
SBP stopped because of too high temperature
Communication with temperature probe was lost
SBP Output power is higher than a threshold above nominal power (105%) (not KO) SBP Output power is higher than a threshold (200%) above nominal power for too much time (KO)

Annexe 5. FAQ
How can I reset my admin password if I have unfortunately forgotten it?
Before version 3.1, there is a generic password that always works: 123TEC. You can use it to connect and change your expert password. As this has been identified as a potential risk for system integrity, we strongly recommend to update to a newer version where security has been improved. From version 3.1, in case of password loss, a new temporary password (valid 24 hrs. after creation) can be issued by CE+T Power. To receive a temporary password, send an email with your T4S serial Number and the date at which you expect to go back on site to change the password to customer.support@cet-power.com specifically requesting a new temporary password. The serial number can be found on the sticker on the T4S, or on screen in `Parameters' then `Info'.
