4.6.2 Starting/stopping the STP pump
There are two methods for the starting/stopping operation with the parallel port.
Use one of them.
1. Contact input
Open the circuit between (19)
–(37).
Method Starting the pump Stopping the pump
1 1) Short the circuit between (1)-(21).
2) Short the circuit between (3)-(21) for 0.3
seconds or more.
However, when inputting this signal
simultaneously with switching "ON" the STP
pump, short the circuit between (3)-(21) for 10
seconds or more.
Open the circuit between (1)-(21).
2 Short the circuit between (1)-(3).
In this case, (21) is not used. Open the circuit between (1)-(3).
