Indicator LEDs

and two operating mode LEDs above and below the mode switch. The top
red LED indicates the module is in bypass operation. The lower green LED
indicates normal (non-bypass) operation.

Relay Module Switch
The three position switch (SW 1) can be used to change module operating
modes. The up position forces bypass operation, and the bottom position
forces normal (non-bypass) operation. The center
Remote position permits
remote mode switching from the Local Aux panel.
Breakout Cable
The breakout Y cable ( Figure 13 ) used between the Local Aux panel and
Emergency Bypass frame includes a BNC connector, which is used for
contact closure.
