Operating Instructions

Please read these instructions before use

Wiring The Remote Alarm:

The remote alarm is a normally low 5V digital signal that goes high when the LVD disconnects. 
It has a 5mA source/sink capability and can be used to remotely monitor the LVD status. 

Wiring With Load Remote Control:

This option enables the remote load connection and disconnection via the load remote control, 
yellow wire. When the yellow wire is grounded the load is disconnected otherwise the load is 
connected. To configure this mode the green wire must be grounded. This option overrides the LVD 

or DDS function but has the same load limitations of 10A continuous or 20A transient.
