How to use External Control Model for BT100-1F

Release Time:2016-12-16

*External Control Input

*Communication Control
The pump can connect to control computer (computer, PLC, SCM) through RS485 serial communication module (shown as below). 

*Analog Single Input function
Set the “Remote Control” in “on” state. External Control Module is shown as below.

*Terminals Definition
Terminal 1    Analog input in 4 – 20 mA, 0 -5V, 0 – 10V external control module to control the speed of pump.
Terminal 2     External control start/stop input. Open, the pump runs; Close, the pump stops.
Terminal 3     External control direction input. Open, the pump runs clockwise; Close, the pumps runs counter clockwise.
Terminal 4:     COM of external control input.



*Pulse Signal Input Function:
Terminal 1    COM of external control input
Terminal 2:    External control start/stop input. Open, the pump runs; Close, the pump stops.
Terminal 3:    External control direction input. Open, the pump runs clockwise; Close, the pumps runs counter clockwise.
Terminal 4:     Pulse input in 0 – 10 kHz pulse external control module to control the speed of the pump.
Terminal 5:     COM of pulse input


*External Control Output
Pump is equipped with output port in order to monitor the status of pump. It adopts DB9 male socket as output port (see as below). External control output start/stop output, CW/CCCW output and pulse output (0 – 100 rpm corresponding to 0 - 10 kHz). Output signal adopts optoelectronic isolation circuit. A pull-up resistor and power supply must be added when using. 

Terminals Definition
Terminal 1   Start/Stop output. Pump outputs low level when it runs; pump output high level when it stops.
Terminal 2  CW/CCW output. Pump output low level when it runs clock wise; pump output high level when it runs count clock wise.
Terminal 8  Pulse output, 0 – 100 rpm corresponding to 0 – 10 kHz.
Terminal 4, 6, 7   COM
