2.0 GENERAL 2.1 Electrical connection to the power supply and pump Main Circuit Breaker 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. The electrical and hydraulic connections must be carried out by competent, skilled, qualified personnel. Other terminals. Terminals 7 and 8 Terminals 15 and 16 MODBUS communication to Slave Controller or BMS N.O. close on fault Terminals 9 and 11 and 10 and 12 for connection to motor thermal protection (microtherms) where available. If not available leave jumper wires in. BIA-DPC1 rev 5 Page 18
2.2 Connections for pump over temperature protection (where supplied with pump). Jumper Leads Note: to realize the pump motor winding over temperature protection, it requires that there must be over-temperature switches embedded in the pump motor winding (microtherms as fitted to Zenit 3ph pumps 2.2 kw or greater). To utilise the pump s over temperature protection connect the pump s microtherm leads to terminals 9 and 11, 10 and 12 and remove the jumper. Note: if the pump is without over temperature switch, please use jumper to connect terminals 9 and 11, 10 and 12. 2.3 Installing float switches and probes. Float switch installation. Do not encase sensor leads, float switches or signal cables in metal pipes. Use PVC or PE tubing. Liquid probe installation. In event of high risk of electrical storms (lightning) or when liquid medium in sump, well or tank is very dirty, it is recommended to use float switches. BIA-DPC1 rev 5 Page 19

8.0 OPERATION 8.1 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 5 Page 39
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. 8.2 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. 8.3 Switching to MANUAL mode. To switch between AUTO and MANUAL model press MODE and STORE keys at the same time for 5 seconds to unlock and go into MANUAL mode. Press the START key to start the pump and the STOP to stop the pump. 8.4 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. 8.5 Pump Protection 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. BIA-DPC1 rev 5 Page 40
8.6 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; Failure Icon Note: the failure displayed above is PUMP STALLED. Repeat for pump B by using B STOP key. 8.7 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: Hold pressing the STORE key and press the A STOP key. The control panel makes a beep sound and displays the accumulative run time. BIA-DPC1 rev 5 Page 41
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. 8.8 Pump disable. To disable a pump independently, in AUTO mode press MODE and A STOP or B STOP at the same time for 2 seconds. A PUMP and MANUAL flashing means pump A is disabled. To restore the pump, in AUTO mode press MODE and A START or B START at the same time for 2 seconds. 9.0 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 5 Page 42
9.1 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. 9.2 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. 9.3 Technical parameters. The following chart shows main technical parameters of communication between the control panel and the slave controller.
