Fig.14 External control connector pin assignment
※
The pair of SAIE-M12B-4-0.5U-FP-M16 is SAIL-M12G-4-1.5U.
When it operates by external control, please supply DC +15V in the user side.
When take external control, please set an inside / external control changeover
switch in driver circuit box in the external control side.
An electric cable for alarm output assumes it under30 meters.
Even when the DC+15V is not supplied (operation stopped), the mechanical
booster pump motor is run by the auxiliary pump operation.
When an auxiliary pump with an pumping speed greater than 240 L/min is used
and the motor reaches an rpm greater than approximately 500 rpm, the motor
system starts and the alarm output turns ON.
