Voltage Monitor
The input voltage, like the load input current can
be externally monitored with the channel control
connectors. The VMON pin of the channel control
connector outputs a voltage of 0~10V to represent
the load input voltage as a percentage (0~100%) of
the rating voltage.

To determine the Voltage Monitor Output
(VMON) , use the following formula;

Where “Rating V” is the rating voltage of the load
module.
Turning on the
Load
A load is turned on when Load On input is set to
On (active low). A load is turned off when the
Load On input is set to Off (active high).
When a load is turned on from the channel control
interface, the load can be turned off from the
mainframe, local module and via remote control.
However the opposite is not true; when a load is
turned off using the channel control interface, the
load cannot be turned on via the mainframe, local
module or via remote control.
