8200B Smart Pump Drive

8200B Smart Pump Drive

8200 series pump dedicated drives are smart all-in-one water supply products with high
protection developed independently by SAJ. Its enclosure is dust proof and water proof. It
can be installed on the junction box of various pump motors and also be connected to
many kinds of sensor signals. The system is easy to operate and cost effective with high
reliability and low noise. Each pump is equipped with a pump drive, which can realize
multi-pump(host and auxiliary pumps) linked operation.

Basic functions
Command running channel Three kinds of channels: 1. operation panel 2. control terminal
3.serial communication port, choose 1 and 2 for host drive and 3 for auxiliaries
Multi-Pump Smart Link One drive in the system can be host and controls auxiliaries(4 at most) to work by communication
mode. Host sends PID feedback to auxiliaries and monitors status of auxiliaries in real time. If
failure occurs, the auxiliary will be skipped.
Integrated PID Advanced PID arithmetic to realize closed loop control system
AVR When grid voltage changes, it keeps output voltage constant automatically. By default,
it doesn’t work at deceleration.
Stall control Automatically limit current and voltage at running period to prevent tripping caused by frequent
overcurrent/over voltage.
Water shortage protection Controller detects that pipe network pressure is lower than water shortage pressure, system stops
working automatically. After set period, it restarts automatically for specified times. If pressure
restores to normal, system works normally. Otherwise, system stops automatically in case of idle
running of pump and prolongs pump lifetime in maximum.
High pressure alarm When pressure exceeds set pressure, it stops automatically to prevent pipe network from high pressure.
Automatic energysaving
Decrease output voltage automatically at light load to save energy.
Password setting 4-bit password can be set with non-zero numbers. Exit password setting interface and the password
will be valid after 1 minute.
Parameter lock Define whether the parameter is locked in running or stopped state in case of misoperation.
Application environment
Installation environment Installed in places without direct sunlight; dust and water proof
Note: 1. No complete dust prevention; 2. No explosion protection
Altitude Lower than 1000m, service in derated capacity above 1000m. Derate 1% capacity every
100m increase in height.
