8100 Smart Pump Drive
8100 series wall mounted (cabinet) pump dedicated drives are smart all-in-one water supply
products developed independently by SAJ. It is installed in the electric control cabinet and can be
connected to many kinds of sensor signals such as pressure sensors, transmissible pressure gauges
and pressure switches. 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.

|Acceleration/deceleration time||Range: 0.01 ~ 360s|
|Start frequency||0.01 ~ 10.00Hz|
|Input frequency range||50/60Hz, fluctuation range: ±5%|
|Output voltage||0 ~ rated input voltage|
|Output frequency||0 ~ 50/60Hz|
|Programmable digital input||6 ways of digital terminal input|
|Programmable analog input||AVI (transmissible pressure gauge): 0 ~ 10V
ACI (pressure transmitter): 0.4 ~ 20mA; able to be switched to 0 ~ 10V by jumper
|Relay output||1 way of output, programmable|
|Open-collector output||1 way of output, programmable|
|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
|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.|
|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.|
|Installation environment||Installation environment should have be without direct sunlight, dust, corrosive gas, inflammable gas,
oil mist, steam, water drop
|Altitude||Lower than 1000m, service in derated capacity above 1000m. Derate 1% capacity every
100m increase in height.
|Environmental temperature||-10℃ ~ +40℃, service in derated capacity for 40℃ ~ 50℃. Derate 4% capacity every 1℃
increase in temperature.
|Humidity||≤95%RH, no water condensation|
|Vibration||< 5.9m / S2(0.6G)|
