INITIAL START-UP OPERATION
1. Place circuit breaker in ON position. The pump may start immediately if system pressure is low.
The PUMP RUNNING and LOW PRESSURE LED’s will be lit.
2. If the Mark IIXG is confi gured for automatic shutdown (AUTOMATIC STOP enabled), the pump
motor will continue to run for the period of time set in the MIN RUN (or OFF DELAY) screen and
then stop automatically, providing the STOP pressure setting has been reached. Both the system
pressure and MIN RUN (or OFF DELAY) time remaining will be shown on the display. Depressing
the STOP push-button during the running period will stop the motor as long as the button is held
in. However, the motor will restart when the button is released if system pressure is below the
stop setting.
3. If the controller is confi gured for manual shutdown (AUTOMATIC STOP disabled), the pump
will continue to run until the STOP push-button is depressed.
4. To stop the motor otherwise, press and hold the STOP push-button and place the CIRCUIT BREAKER
DISCONNECTING MEANS handle in the OFF position.
FOR MANUAL START
1. Follow the initial start-up instructions. The isolating switch/circuit breaker should be closed, the
POWER AVAILABLE LED should be illuminated and system pressure normal, i.e. higher than the
programmed START PRESSURE setting.
2. Press the START push-button. The pump motor should start and continue to run. It will not
stop automatically. The running period timer and pressure switch have no control over this manual
operation.
3. To stop, press the STOP push-button.
4. Starting from a remote START push-button (if used) functions in the same way as the local START
push-button.
5. If the pump motor restarts, system pressure is below the START PRESSURE setting.
FOR EMERGENCY RUN START
1. Put the circuit breaker/isolating switch in the “off” position.
2. Push and lock the EMERGENCY RUN handle. Place the circuit breaker/isolating switch handle in
the “on” position. The motor will start and continue to run until both of the following conditions
have been satisfi ed:
a. The EMERGENCY RUN handle has been turned to “unlock” position and released.
b. The STOP push-button is pushed.
3. To stop the motor with the handle locked in the “run” position, place the circuit breaker handle
in the OFF position, then turn the EMERGENCY RUN handle and release.
4. Return the circuit breaker operator to the ON position.
5. If the pump restarts, system pressure is below the START PRESSURE setting.
