USE OF AUX INPUTS FOR CONTROL CIRCUIT STATUS MONITORING
AUX Inputs left unused for Modes 1-6 may be used for voltage on/off status monitoring of any DC control circuit node. High and
Low voltage status may be monitored. After the Mode is saved, unused AUX inputs will be available in the Digital Input cell. They
may be configured as active-high or active-low. The Off/On threshold is approximately 35 volts DC.
The AUX Input can drive the relay output only. There is no visibility for the status of AUX Inputs used this way on web pages or
through DNP. The relay status is visible as a DNP point so if no other parameter is configured to assert the relay, then the status of
the AUX Input may be known by the status of the relay DNP point
For instance, if Mode 6 is selected and saved and AUX Inputs defined, the remaining unused AUX Inputs will show in the Digital
Input cell. From the Configuration Page:

NOTE
: To configure a Binary DNP point to report the relay state:
• Category = “Other”
• Source = “Relay Activated”
