by inhibiting the ‘Duty’ pump and then recreate the conditions for a normal start to take
place. Check that the ‘Standby’ Pump now starts and runs in place of the inhibited ‘Duty’
pump and observe the pressure values. Verify that the pump motor speeds up / slows
down in accordance with the desired control philosophy.
2. Wait for a normal stop to take place (or create the conditions where this would happen)
and check the ‘Standby’ pump stops. Whilst stopped undo the inhibit to the ‘Duty’ pump
which should now return to normal.
Duty/Assist Sets
1. For ‘Duty/Assist’ applications, run the system up to pressure using the ‘Duty’ Pump only,
then deliberately create the condition(s) which will require the ‘Assist’ Pump to operate as
well. (e.g: open taps to reduce the pressure in the system to a point where one pump only
cannot maintain the required output. Verify that the ‘Assist’ Pump starts and runs together
with the ‘Duty’ Pump and that the desired pressure is duly restored and maintained.
2. Close the taps again (thereby reducing the demand) and check the ‘Assist’ Pump slows
down and stops, allowing the ‘Duty’ Pump to continue on its own.
6. Commissioning/Handover Check
1. Record any indicated voltage / amperage / pressure data / controller passwords for future
reference.
2. Re-check all isolating valves are fully open and replace any cover(s).
With all the isolators ON and the switches and/or control programs set to AUTO, the
pumpset is now fully operational in automatic control mode
.
Note
No manual operation or attendance is required other than for routine servicing and
maintenance checks.
Other than for maintenance purposes, the supply to the Controller(s) and the Pump
motor(s) should never be switched off
