2.0 Installation – DRAINAGE

2.1 Electrical connection to the power supply and pump

DANGER. Electric shock risk.

Before carrying out any installation or maintenance operation, the control panel should be
disconnected from the power supply and one should wait at least 2 minutes before opening the
control panel.

Never connect AC power to output L and N terminals.

Ensure the motor, controller and power specifications match.

If a pump fail situation is detected then the pump will switch to the second pump.

Warning – DRY RUN Protection not active in Drainage with Automatic Pump Mode.

High Level Alarm Delay

High Level Alarm delayed by 15 minutes after activation of High Level Float to allow 2nd Pump to turn on

and assist with pump out.

Note, For 30 minutes after High level Alarm activated, both pumps work concurrently.

Note: for drainage

2.5.1a Drainage by liquid level control WITH AUTOMATIC PUMPS

Stop condition

Liquid level in the sump is below automatic pump float switch off position which will stop both pumps.

Start condition

The control panel alternates power supply between pumps every 240 hours. When liquid level in the sump is
above the automatic pump float switch on position, the pump that is being supplied power will run.

Alarm condition

While pumping, if the liquid level rises in the sump to float switch C up, the control panel will sound the alarm
to warn the user to take further action.

5.0 OPERATION

5.1 BEFORE YOU START – Parameter calibration and erasing.

To achieve best level of protection of the pump, it is essential that parameter calibration be done immediately
after successful pump installation or pump maintenance.

Setting the parameter calibration.

Pump/s must be able to pump water to enable correct calibration. If pumps are calibrated without water,
overload and pump stalled errors may occur later.

If calibration is required without water, please contact White International for advice.

Press the MODE key to switch to manual state. If the control panel is locked press MODE and STORE keys at
the same time to unlock and go into manual mode. Make sure that the pump is not running and LCD screen is

displaying:

Press the A START key to run pump A, confirm the pump and all pipe network is in normal working state
(including voltage, amps etc) with LCD screen displaying:

Press the STORE button. The control panel makes a “beep” and a countdown starts with the LCD displaying:

Control now counts down from 5 seconds.

The pump stops running and parameter calibration is completed with LCD displaying:

Press the B START key to repeat calibration for pump B.

BIA-DPC1 rev 4 Page 38

Erasing former parameter. When pump is reinstalled after maintenance or a new pump is installed, user must
erase the former calibration and a new calibration must be done.

Erasing the parameter calibration.

Press the MODE key to switch to manual state. If the control panel is locked press MODE and STORE keys at
the same time to unlock and go into manual mode. Make sure the pump is not running and LCD is displaying:

Press the A STOP key for 30 seconds; the control panel makes a “beep” sound, and the control panel recovers

the default factory setting and the LCD displays: with Pump No Calibration
flashing.

Repeat for pump B by using the B STOP key for 30 seconds.

5.2 Switching to AUTO mode.

To switch between MANUAL and AUTO mode press MODE. AUTO mode automatically locks control panel.

Under auto state the control panel will run or stop the pump according to the signal from the liquid level probe
or float switch.

Note: under auto state, if the pump is running and user wants to stop the pump, press the MODE key to switch
to manual state and the pump stops.

Note: under auto state, if the input power is cut off and the recovers, the control panel will enter operating
state after 10 seconds countdown

Note: no matter if the control panels is under auto or manual state, if the input power is cut of and recovers
again, the control panel will resume its operation in the same state as before the power being cut off.

5.3 Switching to MANUAL mode.

To switch between AUTO and MANUAL model press MODE and STORE keys at the same time to unlock and go

into MANUAL mode. Press the START key to start the pump and the STOP to stop the pump.

5.4 Alarm Test and Mute.

Under MANUAL mode and pump/s not operating press STORE for 3 seconds to test the alarm.
At any time press ASTOP to mute the alarm.

5.5 Pump Protection

BIA-DPC1 rev 4 Page 39

During pump running, if dry run, overload, over voltage, etc failures occur, the control panel will immediately
shut down the pump running and automatically execute a check for restarting conditions after a built in time
delay has elapsed. The control panel will not recover automatically until all the abnormal situations have been
cleared.

If pump stalled, open phase or other serious failure has occurred, pump user must immediately check pump
and motor.

5.6 Last five failure record

The control panel can memorize the last five failures of pump, so it is very convenient for the users to analyse
the pump running conditions.

Displaying the last five failure record.

Press the MODE key to switch to manual state, make sure the pump is not running and the LCD screen is
displaying:

Hold pressing A STOP key and press MODE key, the control panel makes a “beep” sound and displays pump A
failure record.

Press the A STOP key to quit the failure record display;

Note: the failure displayed above is PUMP STALLED.

Repeat for pump B by using B STOP key.

5.7 Pump accumulative running time

The control panel can memorise how many hours of pump running, so it is very convenient for the pump user
to analyse the pump running conditions and do maintenance.

Displaying the pump accumulative running time.

Press the MODE key to switch to manual state, make sure that the pump is not running and the LCD screen is
displaying:

Failure Icon

BIA-DPC1 rev 4 Page 40

Hold pressing the STORE key and press the A STOP key. The control panel makes a “beep” sound and displays
the accumulative run time.

The pump has run for 23 hours.

Press the A STOP key to quit the accumulative running time display.

Repeat for pump B by using B STOP key.

5.8 Pump disable.

To disable a pump independently press A STOP or B STOP and MODE at the same time.

6.0 Communication link.

The control panel has communication interface, that along with the optional Slave Controller, users can realise
a long distance monitoring function.

This function applies to where the control panel is installed in the basement or pumping room, but users
require to monitor and control the pump on the ground or in a control room.

BIA-DPC1 rev 4 Page 41

6.1 Basic function.

Slave Controller (SC) with communication interface can realize long distance monitoring. In the control room,
users can realize all the functions of the master control panel through the SC, except parameter calibration
and adjusting.

6.2 Special application.

As adopting communication interface, the wire communication distance is less than 1200 metres. For those
installation environments which require a longer distance communication, i.e., mine, water tower, across
railway road and bridge etc., users can adopt RS485 extender, wireless communication or GSM. Please contact
the manufacturer for more information.
