The pump may be started either locally (Manual) or remotely (Auto). The Auto/Manual
switch is located inside the control panel. In Manual mode, the pump is started and
stopped by pressing the ON or OFF buttons on the front of the control panel. In the
auto mode, power from a remote source is supplied to terminals B1 and B2. This
energizes the 1X relay, which allows the pump to run. Or, a relay contact can be
connected to terminals D1 and D2. When the relay contact is crossed, the pump will
run; when the relay contact is open, the pump will stop.

Initial Check
•
Check the cooling water and nitrogen flows for correct settings.
•
Check that the primary lubricating fluid reservoirs have been filled with lubricating
fluid (to the upper limit line).
•
Blank off the inlet.
•
Turn the power to the system on.
•
Momentarily start each pump to verify correct direction of rotation (counter-
clockwise when viewed from the motor end).
If the direction of rotation is incorrect, the position of any two of the three power supply
conductors must be reversed.
