2. Voltage 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 STP
pump, 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).
