the controller will shut the regulator down by removing drive to the input
contactor. This contactor will remain de-energized until the controller is
reset either by selecting the OFF position (remotely or locally) or cycling
the input power off for a minimum of 2 seconds and then back on. The
control board will not recognize momentary over currents caused by load
switching or other transient conditions.
O
PEN CIRCUIT PROTECTION
The micro-controller detects an open circuit by the absence of current in
the regulator output (this will also detect an open or shorted current
transformer). If the output current is less than 1.5 amps, the controller will
shut the current regulator down within one second by removing drive to
the input contactor. This contactor will remain de-energized until the
controller is reset either by selecting the OFF position (remotely or locally)
or cycling the input power off for a minimum of 2 seconds and then back
on.
