Control Power - GE F60 Instruction Manual

3 HARDWARE
CONTROL POWER SUPPLIED TO THE RELAY MUST BE CONNECTED TO THE MATCHING POWER SUPPLY
RANGE OF THE RELAY. IF THE VOLTAGE IS APPLIED TO THE WRONG TERMINALS, DAMAGE MAY
OCCUR!
CAUTION
The F60 relay, like almost all electronic relays, contains electrolytic capacitors. These capacitors are well
known to be subject to deterioration over time if voltage is not applied periodically. Deterioration can be
avoided by powering the relays up once a year.
NOTE
The power supply module can be ordered for two possible voltage ranges, with or without a redundant power option. Each
range has a dedicated input connection for proper operation. The ranges are as shown below (see the Technical Specifica-
tions section of Chapter 2 for additional details):
LO range: 24 to 48 V (DC only) nominal
HI range: 125 to 250 V nominal
The power supply module provides power to the relay and supplies power for dry contact input connections.
The power supply module provides 48 V DC power for dry contact input connections and a critical failure relay (see the
Typical Wiring Diagram earlier). The critical failure relay is a Form-C that will be energized once control power is applied
and the relay has successfully booted up with no critical self-test failures. If on-going self-test diagnostic checks detect a
critical failure (see the Self-Test Errors table in Chapter 7) or control power is lost, the relay will de-energize.
For high reliability systems, the F60 has a redundant option in which two F60 power supplies are placed in parallel on the
bus. If one of the power supplies become faulted, the second power supply will assume the full load of the relay without any
interruptions. Each power supply has a green LED on the front of the module to indicate it is functional. The critical fail relay
of the module will also indicate a faulted power supply.
An LED on the front of the module shows the status of the power supply:
