On the Remote Display Module (in legacy installations) there is a ribbon cable
connecting the face label on cover to the main circuit board. Use care not to
disconnect this cable. If cable becomes disconnected, lift the latches on sides
of ribbon cable connector, insert ribbon cable fully into connector and press
latches back down.
Reposition jumper to enable remote control either “normally on” or “normally
off”, as desired (see Figure 9). Then replace cover and secure with six screws.
When operating a Power Supply using the remote control circuit, power may
be applied through the “Alarm Output” connector or the “Power In” connector
on end panel. If the “Power In” connector on end panel is used, the “Power”
switch must be set to ON (1) position.
Remote control is established by applying 24V
DC to the “Alarm Output”
connector pins as specified in Figure 7. User-applied 24V
DC drives a low
current optoisolator on the main circuit board, turning Power Supply on or off,
depending on configuration of jumper J3.
