COMMISSIONING & TESTING PROCEDURE

RECOMMENDED COMMISSIONING & TESTING PROCEDURE GENERAL NOTES :
Once the system has been powered & the number & type of connected sensors has been correctly programmed into the controller – see page 1 (SPARE ME THE DETAILS), If the system is wired correctly, the controller should after a one minute power / warm up period, be sitting in idle mode. If a fault mode exists for any reason the controller will after a one minute delay, go into alarm mode and display the particular fault that will need to be addressed before proceeding with system testing & commissioning ie : if for example a sensor connected to the HCP7 controller input terminal “X4” has been wired incorrectly and not delivering at least a 2vDC output signal to the controller (in reference to the system common neutral), after a one minute delay, the controller will alarm and display a sensor fault message for sensor 4. Mute the alarm via the remote push button switch connected to terminals “D2″&”M”or use the top right hand button on the controller labeled MUTE. Also note : Ex factory, the fan fault input “D1” is set as a N/O input that closes on fault, if a N/C fault circuit is used (ie to suit air proofing pressure switches or C.T’s) this setting will need to be changed in programming – see page 20. The D1 fault input can be programmed to be interlocked or not with the fan run relay R2 (the default is Not Interlocked). Being interlocked with R2 is a typical requirement if using N/O (=fan fault) such as using an air pressure proving pressure switches or a C.T for fan fault indication such that a N/O input is only seen as a fault when the fan should be producing pressure.
INITIAL CHECKS (black text basic instruction , blue expanded explanation) 1.) Using a volt meter, check the controller is receiving 24 volts power supply .
The HCP7 controller & HGS sensors will operate with either a 24v DC or AC supply. The power supply ACTIVE wire should be connected to the HCP7 “+” power supply terminal, and the NEUTRAL to the controllers “-” terminal. Also verify that the wires being used as the 24v active & neutral supply are also correctly connected to the appropriate terminals on the HGS sensors ..crossed 24V power supply wires between the controller & sensors can in time cause damage to the components and will cause incorrect operation. The power supply neutral wire needs to be connected to the HGS sensors “GO” terminals, and the active to the “G” terminals. The sensor output terminal “Y” will then produce a 2-10vDC measured in reference to the power supply (AC or DC) NEUTRAL (GO) and is relative to 0-100 ppm of CO .
2.) Verify with a volt meter (set to the 20 volts DC scale) that at least 2.0volts DC is being received on all HCP7 controller used “X” input terminals (red meter lead on an “X” input
terminal and the black lead on any “M” or “-” terminal (“M’s” & “-” are internally connected). 2.0 volts DC = 0 ppm CO & every 0.8 volts DC above that equates to +1ppm, ie : 2.40vDC = 5 ppm. Sensor inputs must be connected in sequence without gaps ..ie 4 connected CO sensors would be connected to input terminals – X1, X2, X3 & X4. The number of programmed sensor inputs must have physical connections otherwise a sensor fault will be set. CO sensors need to be connected before any NO2 sensors.
3.) Pressing the “STATUS” button on the HCP7 controller will show current status of connected inputs and outputs in a series of pages that are accessed by further pushing of the STATUS
button. Check that the values & status of the I/O are as expected and are inline with the physical inputs & outputs. The 1st status screen shows the highest CO & NO2 inputs BUT in Time Weighted Average (TWA) reading – meaning the inputs are read & averaged over a settable time window – see page 5. The next page shows the actual current values for each sensor , followed by the output status of the relays etc.
HEVAC CONTROL AGENCIES PTY.LTD 7 / 54 HOWLEYS RD NOTTINGHILL VIC. 3168 PH. 0395626777 www.hevac.com.au P3 11/12/23

4.) Press the “TEST” button on the HCP7 which demonstrates & tests the controllers output response using a virtual sensor input automatically raising from 0 to 60 ppm CO and returning
to 0 over a 5 minute period. For the sake of reduced demo time, most delay times during the test are bypassed and the outputs will respond to the pre-programmed default CO ppm trigger values with minimal delay. Exceeding 9ppm, the Relay 2 fan enable relay, will energise and the vsd or fan should start. As the virtual input increases past 20 ppm, if a VSD is connected to the controllers “Y1” terminal, the VSD should ramp up until maximum speed as the virtual CO input reaches 35 ppm. After this input reaches 55ppm the alarm strobe output should energise (relay R3) and at 60 ppm the siren output will energise (relay R4). Test that the siren can be muted with the site installed momentary “SIREN MUTE” push button (connected between HCP7 terminals “M & D2”). The virtual input will then proceed to slowly return to 0ppm and relative outputs should de-energise in sequence until the controller returns to the idle state and the test automatically ends . This test can also be canceled any time during the test by again pressing the TEST button.
OTHER OPTIONAL SYSTEM COMMISSIONING CHECKING
Sensors are supplied factory calibrated and shouldn’t need checking with calibration gas during initial site commissioning & testing, but if desired follow the procedure on page 5 to check for correct output per 0 & 100ppm CO. It is recommended to have the sensors calibrated every 12 months after commissioning. To aid in testing & fault finding, Hevac HGS-CO sensors are equipped with a basic output indication yellow flashing led to help identify in the field which sensor is producing an output or is in fault condition. The sensor also incorporates a very handy on-board test pin header to aid in field testing the sensor wiring & the HCP7 controllers ability to correctly respond to two different fixed sensor output levels. Beneath the HCP7 connection terminal strip is a 3 way pin header, using the supplied 2 way jumper (which in normal operation is only connected to one pin & having no effect) short the middle & left pins to produce a fixed output level equating to ~ 35ppm CO, which will cause the HCP7 to energise (after 1 minute) the R2 fan enable relay to start the fan or VSD, and will in then ramp up the VSD (if installed) to full speed. If the jumper is fitted to the middle & right pins, a full sensor output level equivalent to over 100ppm (11vdc) will be produced which the controller will see as a fault condition resulting in (after a minutes delay) full fan speed and to put the outputs into alarm mode. Relay 5 (terminal 8) is available for use as a normally energised relay if no faults exist for optional use as a system healthy indication lamp.

FAULT DIAGNOSIS

1.) If the VSD doesn’t respond correctly during the test, 1st check that its getting an on/off enable signal from the HCP7’s FAN enable relay R2. If whilst the controller is producing a modulating output signal to increase the VSD speed and the VSD doesn’t ramp up, verify that the controller is producing a 0-10vdc signal on its “Y1” output terminal by 1st removing the site wire from terminal “Y1” and rerun the HCP7 TEST (button) and test if a 0-10vdc output is being produced between the controllers “Y1″(DC+) & “M” (GND)” terminals, if it does and the drive wasn’t responding, check the field wiring between the HCP7 “Y1” output to the VSD “+” signal input, and the HCP7 “M” (or 24v neutral) to VSD signal ground. Also check the settings in the VSD, ie it is set to recieve a voltage signal input not 4~20mA current input~which is a common error.

2.) If the siren or strobe outputs doesn’t respond, check the relative HCP7 output relays (R3 & 4) are closing & check the field wiring – the MLD95A alarm module black wire is its neutral connection , the white wire energises the strobe & the red wire energises the siren.

3.) If the external Mute button doesn’t mute the siren whilst in alarm mode, check that the switch can provide a voltage free momentary closed contact to the controllers terminals “D2 & M”.

4.) If more then 7 sensors are fitted to the system, expansion modules type EXP7 will be fitted

that allow 7 more sensors with each expansion module fitted. These sensor inputs should also appear in the

status screen pages on the HCP7, if not check that the expansion comms link “E & M” is connected to all

modules. Address links also need to be wired in each EXP7 expansion modules if more then one EXP7

module is installed as follows: 1 x expansion module ..no address links required (= up to 14 sensors)

on 2nd expansion modules fit link from M to D1

(= up to 21 sensors)

on 3rd expansion modules fit link from M to D2

(= up to 21 sensors)

on 4th expansion modules lfit ink from M to D1 & D2

(= up to 28 sensors)

on 5th expansion modules fit link from M to D3

(= up to 35 sensors)

on 6th expansion modules fit link from M to D1& D3

Operational notes

“TIME WEIGHTED AVERAGE” (TWA) is a method used to average out sensor readings to produce an average output value calculated over a set period (time window), whereas “CURRENT VALUE” (CV) produces the actual current real time sensor value. To save energy & meet minimum safety requirements AS1668.2 calls up the use of TWA measured over an 8 hour period, Most CO control systems on the market tend to ignore this and can only respond to current value ( which exceeds requirements but uses more energy ).This controller can be set to use any combination of TWA or CV for the various outputs. By default ex Hevac, we use the custom menu to set all outputs to use current value (CV). The controller can also be set to force ON fan operation between several configurable blocks of time, intended for use when known high periods of traffic are expected and to save cycling and fume build up. The controllers internal time switch is factory preset to force fan operation Monday to Friday in the morning between 7am till 9am and in the evening between 5pm till 7pm (but is adjustable). To enable this feature, an external link or switch must also be connected between terminals “M” & “D3”. This input can alternatively be used as a forced fan run input (for example) from a switch, a movement sensor (with built in run on timer) or & a thermostat, this forced fan run “speed” is also programmable with a factory default of 100% vsd or high speed. The controller also makes use of an “Idle Run Timer” routine that keeps track of the last fan operation time and automatically starts the fan to satisfy minimum ventilation requirements. The preset factory settings force fan ON operation after 24 hours of idle time and then to run for 10 minutes , both gap & duration settings are user adjustable. HEVAC have also included a feature to Inhibit this forced ON operation by use of another internal time switch, which blocks the Idle Timer triggering fan operation between certain hours so as not to cause unnecessary noise (for example) during night hours in an apartment building. The factory settings for this inhibit timer is to block operation between the hours of 10pm till 9am , Note : This inhibit routine does not stop a genuine fan start call due to a build up of CO or NO2 which is enabled to operate 24/7 as per AS1668.
The number of connected sensors is user adjustable in the menu system under the password protected ” CONFIGURE CONTROLLER ” sub menu. The password is 9562. Leave unused X & D inputs open.
Analog output “Y2” is factory preset as a 10vDC output signal source for use (as example) as a EC fan full speed signal source via a “Auto/Manual” selector switch or for use as a sensor I/P test = full scale. As of Jan. 2020 this Y2 output can now also be set to mirror the output of Y1 where more then 3 vsd’s need to be driven (each Y output can drive 100mA = ~ 3 typical VSD’s).
This controller has a simple time stamped data logger to help diagnose faults and system behavior. Also for optional use, Relay 5 acts as an “I’m OK” output which holds relay 5’s contacts closed (on) when the controller has power, is operating correctly, there are no sensor faults and no interlocked fan faults. The fan fault input “D1” can also be user set such that the controller will respond to an opening contact (N/C) or closing contact (N/O) contact (default) to “M” on fan fault and whether the fault input is internally interlocked with the fan run relay.
Relay 5 (terminal 8) is available for use as a normally energised relay if no faults exist & controller has power for connection to an optional system healthy lamp.

AS1668.2 – 2012

COMPLIANCE

***NOTE ***: AS1668.2-2012 Calls for CO ppm sensor response to be based on a Time Weighted Average (TWA) set over an 8 hour period, and with different O/P ppm trigger values depending on the space being used as an occupied or unoccupied CarPark. Hevac has found that although the specified settings for unoccupied carparks satisfy the heath & safety standards and conserve energy, they give poor comfort response to sudden build up of annoying fumes from an idling car or forklift etc, So as a reasonable compromise, Hevac has preset the HCP7 controller to exceed the AS1668.2 requirements, using the controllers “CUSTOM” programming menu to set all outputs as “CV”. The Fan Enable relay (R2) triggers at 15ppm CO with a 1 minute ON delay, the VSD ramp to start from 20ppm & ramp to 35ppm CO (or if 2 speed on/off control selected the High speed relay to energize at 35ppm & off at 20ppm), the Strobe light O/P set to 55ppm CO as an early warning of high CO contaminants & the Audible Alarm O/P’s set to trigger at 60ppm CO. The site commissioning technician can change most settings (with the custom menu) or select one of the inbuilt preset occupied or un-occupied programs that fully comply to the standards, but compliance to meet minimum standards then shifts from HEVAC to the programmer. Note : AS1668.2-2012 no longer calls up the use of NO2 sensors, although HEVAC still recommends their system inclusion particularly when many diesel trucks or cars use the parking facilities. The “CONFIGURE” menu for editing is password protected, the password (is the 1st 4 digits of our phone number) 9562. A 3rd party Modbus connected monitoring / data logging module c/w web interface is also available if required, although the controller does now include a simple 20 event data logger inbuilt. The standards call for the maximum distance between sensor locations not to exceed 25 meters with sensors mounted between 750mm & 1800mm above floor level. Please refer to the standards for other criteria that affect system compliance. Relay 5 (terminal 8) is available for use as a normally energised relay if no faults exist & controller has power, for connection to external fail mode interlocks or & system healthy indication.

IT SHOULD BE NOTED THAT THE CODE DOESNT ACTUALLY CALL UP THE REQUIREMENT OF A STROBE LIGHT , THIS HAS BEEN A TRADITION THAT CONTROL SUPPLIERS HAVE ALSO SUPPLIED AND SET TO TRIGGER AS AN EARLY WARNING BEFORE THE REQUIRED SIREN TRIGGER POINT IS REACHED.

SET TIME SWITCH for D3 (INTERLOCK) FAN RUN
The controllers internal time switch to force ON fan operation (enabled by also fitting a link between terminals D3 & M) can be easily programmed for multiple ON/OFF switching times per day. The controller comes factory preset for forced fan ON operation to cover the typical peak traffic times for morning & evening – monday to friday from 7am (event 01) till 9am (event 02) & from 17:00pm (event 03) till 19:00 (event 04). This application requires a permanent link to be fitted between terminals D3 & M.
P11 25/05/18

SET TIME SWITCH for D3 FAN RUN CONTINUED
To edit settings, from the normal running screen, Press the fascia button labeled “ENTER”. Scroll down through the menu tree with the “DOWN” arrow button till “SET TIME SWITCH for D3 FAN RUN” is displayed. Press the “ENTER” button to open this menu. The existing detail for switching event 1 is displayed. Unlike other time switches, this controller has very flexible unassigned switching events (instead of fixed sequential ON then OFF routines). Time switching events can be set to switch (change state) at any time & day/s, and set as a switching ON event or OFF event. With this method, multiple ON / OFF events can be set on individual days or groups of days (crossing midnight is no issue). 18 switching events are available. Alternatively the D3 & M link can be used as an external manual forced fan ON input from some other device , ie manual switch , thermostat or a movement sensor (c/w built in run on timer). It can be interlocked with time switch times to allow external forced operation during programmed times or if no time switch OFF time entered the external interlock can trigger operation as required 24/7.
P12 25/05/18

VIEW EVENT ON HISTORY

The controller now has a simple 20 event data logger that records input events that cause an output response to help diagnose alarm causes and system behavior. Note : After 20 events are recorded new events overwrite the oldest event.
To access the logger, press the fascia ENTER button to open the menu system, using the DOWN button, scroll down through the menu until “VIEW EVENT ON HISTORY” is displayed. Press the ENTER button to open this menu & view the 1st (if any) ON event triggers. The LCD display shows the event # starting at 01, followed by the event description and the sensor input number that caused the event.
