Trlys1B Compatibility; Trlys1B Installation - GE Mark VIeS System Manual

6.5.1 TRLYS1B Compatibility

The terminal board supports simplex and TMR applications. The I/O pack plugs into the DC-37 pin connectors on the
terminal board. Connector JA1 is used on simplex, and connectors JR1, JS1, and JT1 are used for TMR.

6.5.2 TRLYS1B Installation

Connect the wires for the 12 relay outputs directly to two I/O terminal blocks on the terminal board. Each block is held down
with two screws and has 24 terminals accepting up to #12 AWG wires. A shield terminal strip attached to chassis ground is
located on to the left side of each terminal block.
Connect the solenoid power for outputs 1-6 to JF1. JF2 can be used to daisy chain power to other TRLYs. Alternatively,
power can be wired directly to TB3 when JF1/JF2 are not used. Connect power for the special solenoid, Output 12, to
connector JG1.
Note These jumpers are also for isolation of the monitor circuit when used on isolated contact applications.
Jumpers JP1-JP6 are supplied with the board. The appropriate jumper should be installed if power to a field solenoid is
required. Conduct individual loop energization checks as per standard practices and install the jumpers as required. For
isolated contact applications, remove the fuses to ensure that suppression leakage is removed from the power bus. If both the
jumpers and the fuses are not removed, external power will be connected to the suppression circuits in some operating
conditions.
