2. Connect input
Short the circuit between (19)––(37).
Method Starting the pump Stopping the pump
1 1) Supply 12 to 24 VDC to the circuit between
(21)––(1).
2) Supply 12 to 24 VDC to the circuit between
(3)––(1) for 0.3 seconds or more.
However, when inputting this signal
simultaneously with switching "ON" the power
unit, supply 12 to 24 VDC to the circuit between
(3)––(1) for 10 seconds or more. Connect the (1)
pin to 0 V of 12 to 24 VDC.
Shutoff the circuit between (21)––(1).
2 Supply 12 to 24 VDC to the circuit between (3)––(1).
In this case, (21) is not used. Shutoff the circuit between (3)––(1).
