BoosterControl Advanced
Motors with thermal circuit breakers:
Motors with thermal circuit
breakers:
1. Ensure that the inputs/outputs are galvanically isolated from the thermal circuit
breaker inputs.
2. If thermal circuit breakers have not been safely isolated from the low-voltage
mains, decouple the signals using coupler modules.
3. Connect the thermal circuit breaker to BoosterControl Advanced.
Motors without thermal circuit breakers:
Motors without thermal
circuit breakers
1. Bridge the thermal circuit breaker connection on BoosterControl Advanced.
Observe terminal wiring diagram.
5.4.4 Connecting the pump contactors
The last two terminals can also be used as outputs for signal relays.
1. Observe the terminal assignments on the printed circuit board.
(ðSection5.4.1,Page14)
2. Connect to power supply:
- External 24 V to terminal strip J601, COM terminal
or
- 230 V from L1 terminal to terminal strip J601, COM terminal
3. Connect pump contactors:
- Terminal strip J601, terminals P1, P2, P3
4. For 6 pumps also use the following additional terminals:
- Terminal strip J103, terminals P4, P5, P6
5.4.5 Connecting the pressure sensor
1. Observe the terminal assignments on the printed circuit board.
(ðSection5.4.1,Page14)
2. If a 2-wire sensor is to be used:
- Terminal strip J404, terminals 24 V and +
3. If a 3-wire sensor is to be used:
- Terminal strip J404, terminals 24 V, + and -
5.4.6 Connecting the dry running protection device
Dry running protection can be effected by means of a pressure sensor or pressure
switch fitted on the suction side.
1. Connect the pressure sensor, if any:
- Terminal strip J405, terminals + and -
2. If available, connect pressure switch:
- Terminal strip J403, terminals RDP and COM
3. If no pressure switch is used, bridge the pressure switch terminal:
- Terminal strip J403, terminals RDP and COM
5.4.7 Other connections required depending on the operating mode
Cascade control
No further connections required.
Cascade operation with jockey pump
Ensure that the jockey pump is sized to act as a base-load pump and not as a peak-
load pump.
