OPERATION
Low Voltage Input (Blue Wire):
The blue wire carries the +12-24VDC maintained input Control ON signal to the
PWP120277. Applying 12-24VDC to this input closes the PWP120277 load relay.
Removing the voltage returns the relay to its normal state. This input is intended
for sensor or control device input.
Over Current Protection:
The PWP120277 contains built-in short circuit and thermal protection circuitry
that shuts down the +24VDC output (red wire to sensors) to prevent permanent
damage to the power pack. Removing the excess load from the output restores
the PWP120277 to proper operation. The excess load can be connected to another
power pack.
LED Indicator:
The LED indicates the following conditions on the PWP120277:
• LED OFF: no power to the PWP120277, or the +24VDC output is shorted.
• LED ON, blinks once every 5 seconds: the relay is closed (load ON).
• LED ON continuously: the relay is open (load OFF).
• LED blinking continuously: current output limit is exceeded (too many
sensors are connected to the power pack); +24VDC output shut down.
