Alarms And Alarm Relay Output - CD Automation REVEX 2PH User Manual

REVEX
2PH from 30A to 40A
This input accepts current, voltage and potentiometer signals. The signal is interpreted by comparing its
measured value to the input's full scale. For example, the signal is 50% when the analog input detects 12mADC
and the input is configured to receive 4 to 20mADC.
Configure the power controller to recognize the signal and how the power controller uses it on the hardware
menu; see "Analog In 2" on Paragraph 9.4.4 Hardware menu. For instructions for wiring see paragraph 8.2
Schematic.

11.4 Alarms and Alarm Relay Output

When an alarm occurs and while the condition persists, the alarm relay is de-energized. The alarm relay is
energized when power is supplied to the controller's electronics via the auxiliary power input and there are no
alarms.
Choose which conditions determine the alarm relay output with the Alarm Function setting on Paragraph 9.4.4
Hardware menu.
