DANGER Electric shock risk. Before carrying out any installation or maintenance operation, the controller should be disconnected from the power supply and the person should wait at least 2 minutes before opening the controller. Never connect AC power to output L1 & N1 / L2 & N2 terminals. Ensure the motor, controller and power specifications match. - Page 19 Connections for pump over temperature protection (where supplied with pump) Jumpers Lead Pump Shell Pump Shell Over Temperature Over (Thermal)Switch Temperat Pump B Pump A (Thermal) Switch NOTE: To enable the pump’s over temperature protection, connect the pump’s thermistor leads to terminals 14 and 15, 19 and 20 and remove the jumper.

Page 25: Operation
OPERATION 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. 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 Press the A START... -
Page 26: Erasing Former Parameters
ERASING FORMER PARAMETERS: 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: 2. Press the A STOP key for 3 seconds; 1. -
Page 27: Switching To Manual Mode
SWITCH TO MANUAL MODE: To switch from Auto mode to manual mode, and if the controller is under Auto screen lock, then press MODE and STORE button simultaneously until the countdown timer stops and mode switches back to manual. Press the START key to start the pump and the STOP key to stop the pump. -
Page 28: Pump Accumulative Running Time
NOTE: The failure displayed above is PUMP STALLED. Repeat for pump B by using B STOP key. PUMP ACCUMLATIVE RUNNING TIME: The controller can memorize how many hours that pump has run, so it is very convenient for the pump user to analyze the pump running conditions and do maintenance. -
Page 29: Communication Link
COMMUNICATION LINK The controller has communication interface, between the pump controller and computer/SCADA/BMS, users can realize a long-distance monitoring function. This function applies to where the controller 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. -
