Following are the safety instructions which must be followed by the service
partners or user while installing & operating the product. If ignored, physical
injury or even death may happen. Read the safety instructions before handling the
system.
NOTE (Notes or attention to ensure safe operation)
Important
The manufacturer is not liable for malfunctioning if the product is not correctly
installed, damaged, modified and/or put to run beyond the working range as
given in this manual.
The manufacturer reserves the right to make any modifications to this product
from time to time.
SAFETY
WARNING
If these safety instructions are not observed, it may result in
malfunction or damage to the equipment.
All electrical connections must be carried out by skilled and qualified
personnel.
Never connect AC power to output L1 & N1 / L2 & N2 terminals.
Ensure the motor, controller and power specifications are matching.
CAUTION
If these safety instructions are not observed, it may result in
personal injury.
Before carrying out any installation or maintenance operation, the controller
must be disconnected from the power supply.
Don’t open the cover while the pump is running.
Don’t put wire, metal bar filament etc. into the controller.

Thank you for choosing a DPC Series Digital Pump Controller.
The Digital Pump Controller model is easy to use, programmable controller and
protection device for direct start with single phase two pumps with output power
from 0.37kW - 1.5 kW (1.5 - 15A) each.
The controller has many operation modes for adapting different pumping
applications. Important features that distinguish the DPC Series Digital Pump
Controllers from other controllers are the push button calibration for overload and
the ability of dry run protection without float switches. It shows pump parameter,
status and faults, etc.
APPLICATIONS:
The controller is useful in all cases where there is a need to control and
protect two pump installations and managing the automatic operation by a
variety of switching methods.
Typical applications:
Water supply
Irrigation
Sewage
Booster sets
Rainwater reuse
Stormwater
FEATURES:
Built-in function switch for:
- Drainage by liquid level control through float switches
- Boosting water supply by pressure control through pressure switch and tank
- Transfer of water by liquid level control through float
switches Dry run protection without float switches
Auto/ manual switch with screen lock in AUTO mode
Dynamic LCD displaying for pump running status
Protect the pump against many faults
Push button calibration
Pump accumulative run
time Last five fault records
RS485 communication Modbus
Starts and stops the pump in accordance with liquid levels or pressure settings
Pump shaft anti rust feature

MEANING OF THE ICONS SHOWN ON THE LCD:
The parameter configuration icon,
when this icon appears, controller is in
manual parameter adjustment mode.
Time displaying icon, when this icon
appears, it mean controller is displaying
some parameter of time, eg: pump dry
run trip time(units: seconds).
Pump fault icon, when this icon
appears, it means controller is
displaying some fault condition.
Network connection error icon, when this
icon appears, it means there is no network
connection or network connection error
between pump controller and
computer/SCADA/BMS.
Network normal connection icon, when
this icon appears, it means the network
connection between pump controller and
computer/SCADA/BMS.
