FIGURE 2-4. LOAD CONNECTIONS, REMOTE SENSING
2.7.3 SETUP FOR FAIL SAFE/INTERLOCK PROTECTION
This feature requires disassembly and modification of the unit and
implementation is permitted only by authorized service personnel.
To enable the Fail Safe/Interlock Protection feature, refer to the Service Manual for component
locations and remove the cover of the unit. Locate board A2A5, then cut or unsolder the test
loop wire of TP10 on A2A5.
Once the feature is enabled, a short is required across pins 6 and 7 of the Parallel/Serial Protect
In Port for the unit to function (see simplified diagram, Figure 2-5). For example, installing a local
jumper across pins 6 and 7 of the Parallel/Serial Protect In Port mating connector will cause the
unit to shut down with the red FAULT LED lit if the Parallel/Serial Protect In Port mating connec-
tor is disconnected.
Once the unit shuts down, even though power is applied to the input, no transfer of power to the
output will occur. To restart the unit it is necessary to either toggle the POWER ON/OFF input
circuit breaker on the front panel or, on units with a front panel keypad, press the RESET key.
