SELECTING THE MOUNTING POSITION
Choose a location where the module will be protected from the elements, temperature extremes or heavy vibration. The TTA-SIM is designed to be wall mounted at any location as long as it does not create a tripping hazard or expose the TTA-SIM to impact damage.
Important: The TTA-SIM is an electronic unit. Take the following precautions to avoid damage to electronic components: · Handle with care and avoid mechanical shock and impact · Keep dry · Avoid exposure to static electricity · Avoid contact with metal filings, grease, pipe dope and
other contaminants
MOUNTING THE TTA-SIM
· Plan cable/conduit alignment and drill holes as necessary. Cable entries should all be located in the open space at the right hand of the TTA-SIM (see Figure 2). A typical installation will require holes to accommodate the following cabling: – Incoming power supply – TraceTek sensor leadwire – [optional] telemetry cable (for RS-485 communication) – [optional] cable for relay contacts to remote alarm
· Secure the TTA-SIM enclosure to any convenient vertical surface using the four corner mounting holes and hardware suitable for the selected surface.
· Rough-in conduit as required and pull the cables for power and telemetry. Leave approximately 20 cm (8 in) for connection to TTSIM terminals. Pull in the sensor circuit leader cable.
Note: Rough-in and final connections do not have to be completed at the same time, however, make sure to replace the cover and tighten the cover screws if the enclosure will be left in a partially installed condition overnight or longer.

POWER SUPPLY OPTIONS
The TTA-SIM has two power supply options available. Depending on the version being installed and local regulations, the wiring requirements may vary. In all cases, be sure that each TTA-SIM receives supply voltage from one and only one source.
Important: Power supply voltage must be within range specified on TTA-SIM label (located on inside of enclosure cover; the information is also located on TTSIM top label).
CONNECTIONS FOR POWER
Power and ground (earth) connections to the TTA-SIM are made using the large cage-clamp power terminal blocks at the right end of the DIN rail as shown in Figure 3. Cut back the power wires to fit and strip to expose approximately 6 mm (1/4 in) of conductor. Push the tip of a small flat-blade screwdriver into the cage clamp actuator to open the terminal, then insert the wire into the terminal and release the clamp by removing the screwdriver. Note: In order to provide maximum electrostatic discharge protection, and to be CE compliant, the TTA-SIM must be grounded.

CONNECTIONS FOR ALARM RELAY (OPTIONAL)
Connections to the TTA-SIM relay are made using the lever operated cage-clamp terminals located on the relay unit (see Figure 5). The software programmable TTA-SIM relay contacts may be used for local or remote annunciation, to control a valve or other device, or for connection to a control automation system contact input. The relay can be programmed to alarm on leak only or on either leak or sensor fault. The relay can also be programmed to be ON (coil energized) or OFF (coil de-energized) to signal an alarm (see table below). The relay can be programmed using a TTDM-128 (see TTDM-128 User Manual).

Communications setup
Note: This section can be skipped if serial communication is not being used.
If the TTA-SIM will be connected to a Raychem TraceTek TTDM or other host system using RS-485 serial communication, the end of line (EOL) jumper and network address must be set.
Place the End of Line Jumper in the correct position
The End of Line Jumper on the TTSIM-1A or TTSIM-2 unit must be set in the correct position as follows (use a small needle nose pliers to grasp the jumper):
· On the last TTA-SIM in the network communication circuit, place the jumper on the two pins closest to the EOL mark as shown in Figure 7(a).
· On all other TTA-SIMs or TTSIMs in the network, place the jumper as shown in Figure 7(b).

NETWORK ADDRESS ASSIGNMENT
When used in a communication network, each TTA-SIM module must have a unique address assigned to it in the range 001 to 127. All TTA-SIM units are shipped from the factory with their network address pre-set to a value above the range of valid addresses, in order to prevent communication conflicts during system startup and configuration. Each TTA-SIM must therefore be configured to a unique address before it can communicate with the TTDM-128 or other host.
To set the TTA-SIM network address, repeat the following procedure for each TTA-SIM. Perform the complete procedure one module at a time:
· Using a small needle nose pliers, place the TTA-SIM configuration jumper in the CFG position, as shown in Figure 8(a).
· Using the TTDM-128 or host system, assign the new TTA-SIM address (refer to the TTDM-128 User Manual or the TraceTek System Integration Manual for instructions).
· Place the configuration jumper in the normal operating position, as shown in Figure 7(b), or remove it completely (the jumper is not required in normal operation).

Operating Instructions: TTA-SIM-1A
No user maintenance is required! There are no user adjustments or calibrations that can be performed in the field.
Each TTA-SIM is tested and calibrated at the factory. An operating TTA-SIM runs a continuous self check routine and reports any discrepancies to the TTDM-128 or host computer. If the TTA-SIM or the network wiring fails in such a way that the TTA-SIM cannot communicate with the host, then the host reports the failure as a communications failure.
Status Indicators
There are 5 LED’s on the TTA-SIM-1A circuit board to indicate: power, communications (inbound and outbound), sensor status (leak detected and trouble). See Figure 9.
The green Power LED will be ON and will blink once every 5 seconds when the TTA-SIM is powered and fuctioning correctly. Table 1 lists various sensor status conditions and possible corrective actions. Table 2 lists communication status conditions (applicable when the TTA-SIM is used in a network system).
