Operation

5.2 Auto Operation

System can run up to 4 pumps/VFDs in Auto Operation. All pumps may stage and run variable speed.

Confirm the setup of the following items:

4.10.1

Total # of pumps

Up to 4

4.10.3

PV stage speed %

95%

5.2.0 Local automatic operation

With the JUMPER connected on Terminal 200 and +24V check that the LED indicators on the Operator

Interface Panel (OIP) for two pumps are as follows:
LED

Condition

Meaning

Start/Stop

Off

System is stopped.

No pumps running.

Pump 1 On/Off

Flashing Green

Pump1 is enabled but not on.

Pump 2 On/Off

Flashing Green

Pump2 is enabled but not on.

Take note of the pump sequence. Only the first pump in the sequence will run in normal operation. The second

pump is a standby and will run only if the duty fails. To change which pump is the duty pump press the

4 key.

Press the

START/STOP key. The Off LED will turn solid green and the message START UP will be displayed.

After a start-up delay, the duty pump LED will turn solid green indicating that it is running variable speed. It will

then try to maintain setpoint by varying pump speed. The lag pump will stage on if required.

5.2.1 Remote automatic operation

With the Remote start/stop contact is connected on Terminal 200 and +24V, check that the LED indicators on

the Operator Interface Panel (OIP) are as follows:
LED

Condition

Meaning

Start/Stop

Off

System is stopped.

No pumps running.

Pump 1 On/Off

Flashing Green

Pump1 is enabled but not on.

Pump 2 On/Off

Flashing Green

Pump2 is enabled but not on.

If a pump is not running this means the start contact (from the energy management system or other source) is

not closed and the controller has not been given a start signal.
Once operating in remote it is possible to stop operation (i.e., override the remote start command) by pressing

the

START/STOP key on the OIP.

5.3 Pump Rotation

1. It will be necessary to operate all pumps in variable speed to check for proper rotation.
2. Place the AquaForce into operation as described in previous sections.
3. Run each pump in auto noting rotation in each.
4. If rotation is wrong, exchange the wiring on two motor phases.
NOTE: Changing phase at VFD input does not change output phasing.

DANGER:

• High voltage 3 phase power can kill. Pumps can start automatically. Disconnect and lock-out power prior

to servicing pumps. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS

PERSONAL INJURY, DEATH, AND/OR PROPERTY DAMAGE.
