Wiring
Connect the external signal cable.
a. Use a precision screwdriver to connect signal wires to the signal-
line terminal block.
b. Attach the power-line and signal-line terminal blocks to the PCB.
c. Adjust the slackness of the signal cable, pulling it out.
d. Hand-tighten the cable nut.
*
The external signal cable should be sealed by the cable gasket.
Wiring diagram
When a no-voltage contact is used
When an open collector is used
*
Reverse polarity of the analogue signal input upsets the proportional control or may break the PCB.
*
Reverse polarity of the open collector stop and pulse signal inputs must be avoided. The terminal 6 and 9 are plus
(+), and terminal 10 is minus (-). The maximum applied voltage from these terminals is 12V at 5mA.
Mount the terminal case to the control unit.
Fasten fixing screws evenly to 0.3N•m.
NOTE
Always check that the case gasket are fitted. Or the liquid may enter the control unit and failure may
result.
