Install a jumper on the center pair of pins when it is necessary to have the compressor automatically
restart after a power interruption. There will be a brief delay, then the controller will resume operation if
the selector switch is in its ON position. This feature should only be enabled when the owner determines
that it is safe to do so. It is recommended that compressor access be limited to only trained service
personnel when this feature is used. The controller recalls any temperature shutdown or advisory
conditions which were in effect prior to the power interruption. Put the switch into the OFF position to
reset the controller.
Regardless of the jumper, if the switch is in the OFF position, the controller will be stopped and ready
when power is applied. Turn the switch to ON to start operation.
Temperature Shutdown
- For test purposes, the high temperature shutdown may be set lower. Install a
jumper on the pair of pins furthest from the edge of the controller. The shutdown will occur prior to the
compressor reaching its normal operating temperature. Disconnect power, remove the jumper, and close
up the control box.
CONNECTION TO EXTERNAL CONTROLS
Remote on-off control of the compressor requires only a simple two-wire control, with an isolated contact
suitable for 120 volts, 1 amp. This may be a switch, a timer contact, or a PLC output. To connect, simply
run the two wires to the control box, remove the jumper between terminal 1 and terminal 7 and connect
the two wires to terminal 1 and terminal 7.
The compressor will operate normally whenever this contact is closed. Note that the switch on the
compressor is always the master control; the compressor will not operate unless the control is reset and
the switch is in the ON position.
When the remote contact is opened, the compressor will immediately unload, run for its programmed auto
time, and stop. If it was already unloaded or stopped, it will simply continue. The compressor will remain
stopped until the remote contact is closed to resume automatic operation.
