Cl
2
etc.)
RUN/STOP* ：
Toggle this switch to run / stop the pump.

in highest pulse rate immediately when
press both at the same time.
2.
External
4~20mA Mode
(Optional)
In this mode pumping pulse rate vary proportionally to the
external 4~20mA current signal.
This mode is suitable for proportionally dosing procedure.
Generally pump is controlled by a P.I.D. controller.

signal to control the pump)
For example
：
The pump works 4 pulses when accept 1
signal.
external signal(1p)
pump action (4p)
