Control Panel Overview
The Dual Pump-out Control Panel controls the operation of 2 (two) mains powered submersible
pumps with the use of control float switches within the wet well. The panel is manufactured to
comply with Australian Standards & for the pumping & float controls to be housed Class 1 Zone 2
Hazardous areas as long as the field equipment is approved for that area.
Panel Connections:
Isolator Terminals
A & N - 240VAC Supply
L1, L2, L3 & N - 415VAC Supply
Field Terminals
Pump 1 –Overload 1, Terminals T3 & N1 (N Link) or T1, T2, T3 & N (415V supply)
Pump 2 –Overload 2, Terminals T3 & N2 (N Link) or T1, T2, T3 & N (415V supply)
Terminals 10 & 11 –Duty Float Switch. Float switch up pump on, float switch down pump off. (Close on Rise)
Terminals 10 & 12 –Standby Float Switch. Float switch up pump on, float switch down pump off. (Close on Rise)
Terminals 10 & 13 –High Level Float switch. Float switch up alarm on, float switch down alarm off. (Close on
Rise)
Terminals 2 & N –240V Remote Alarm
Panel Facia:
The front of the control panel housed switches & indicating lights allowing the operator to see what is
happening within the pit in regards to pump operation & alarm conditions.
Indicating lights:
Power on Will indicated if mains power is available at the panel control circuit
High Level Will indicate when the pit is at high level
Pump No1 Run Will indicate when Pump No1 is running
Pump No1 Fail Will indicate when Pump No1 has failed via overload
Pump No2 Run Will indicate when Pump No2 is running
Pump No2 Fail Will indicate when Pump No2 has failed via overload

Control Switches: (housed on Inner door)
Pump No1: Manual/off/auto controls the operation of Pump No1
Manual, the pump will run continuously & is not under the control of float switches
Off, the pump will not operate.
Auto, the pump will run when told to start via the float switch in the pit.
Pump No2: Manual/off/auto controls the operation of Pump No2.
Manual, the pump will run continuously & is not under the control of float switches.
Off, the pump will not operate.
Auto, the pump will run when told to start via the float switch in the pit.
Duty Selector: Pump 1/auto/pump2 controls the alternation of the mains powered pumps
Pump 1, when selected will make Pump No1 the duty pump. Pump No2 will be
standby.
Auto, when selected in auto the mains pumps will alternate after each operation
Pump 2, when selected will make Pump No2 the duty pump. Pump No1 will be
standby.
Audible Alarm: The panel has an audible alarm that sound when a fault condition has been
registered, Pump 1 fail/Pump 2 fail/High level. Once an alarm sounds it can be
silenced by pressing the alarm mute pushbutton. If a second fault condition is
registered during this period the alarm will once again sound to warn of this fault.
The audible alarm has a time feature to comply with noise regulation, once the
alarm sounds it will sound for 5minutes & then silence itself for a further
15minutes before sounding again. This cycle will continue until the fault is rectified
or the mute pushbutton pressed.
Float Switch Operation:
The pumps are controlled via float switches in the collection pit of which there are
3. Duty float switch or the lowest float switch controls the duty selected pump. The
pump will start when the float rises & stop when the float falls.
Standby float switch or the middle float switch controls the standby selected
pump. The pump will start when the float rises & stop when the float falls.
High Level float switch or the top float switch operates the high level alarm. The
alarm will start when the float rises & stop when the float falls
Note, for a 2 float system bridge terminals 12 & 13.

Pump Fail: Pump fail is indicated the red light on the panel facia is flashing. To reset this
pump fail condition open the control panel door & in the bottom left of the control
panel are the 2 motor starters c/w their thermal overload relay. On the right hand
side of the overloads is a small blue tag which will be raised if the overload has
tripped. Push this tag back down to reset.
Voltage free Contact:
The control panel is fitted with a voltage free alarm contact for a building
monitoring system. The relay contact is rated at 2A 240V & is a fail safe. When
the panel is powered the relay will be energised & will drop out (change status) if
power fails/either pump fails / or a high level is reached.
