Analog Input 2: Set Point Or Feedback; Alarms And Alarm Relay Output - CD Automation REVO C 2PH 690V User Manual

REVO C 2PH from 60A to 800A - 690V

11.3 Analog Input 2: Set Point or Feedback

What this input does is user-configurable. Connect an analog signal that indicates:
• An alternate set point signal
• Measured power, voltage or current from an external device used as feedback.
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 8.7 and
8.9 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.

NOTE! The alarm relay output indicates an alarm whenever the temperature of the heat sink
is too high even when Alarm Function on the hardware menu is set to None.
NOTE! The power controller monitors for heater break or short circuit conditions only when
included in the option selected for Alarm Function.
