CON4 Connector (Optional accessory)
This is a connector for remote input/output signals.
This connector can maintain compatibility with the remote I/O signal of the STP-200/300/400
series.
The remote input signal from the CON 4 connector is valid by setting No.4 switch of the
DSW-B on the top panel to "ON". In this case, remote input from I/O TB2 terminal is invalid.
(Refer to Figure 6.3, "STP Control Unit Top Panel" for the position of "DSW-B")
This connector is GP-IB
8.3.1
Remote Input Signals
Use input signals according to Table 8.5 and Figure 8.3. See Section 7.6, "Remote Operation
(CON4)".
This input signal is valid only when No.4 of the DSW-B is "ON" in the remote operation.

Pins for inputting the RESET signal.
When inputting 24 Vdc between (2)-(14) for 0.3 seconds or more,
the "FAILURE" lamp is turned off.
Connect the (+) side to (2), and the (–) side to (14).
(It is an equivalent to the pin for inputting the "POWER OFF"
signal of the STP-200/300/400 series)
Pins for inputting the START signal.
When inputting 24 Vdc between (3)-(15) for 0.3 seconds or more,
the pump starts operation.
However, when inputting the signal simultaneously with switching
"ON" the breaker on the rear panel, continue to short the circuit
for 5 seconds or more.
Connect the (+) side to (3), and the (–) side to (15).
Pins for inputting the STOP signal.
This STOP signal has priority over the START signal.
When inputting 24 Vdc between (4)-(16) for 0.3 seconds or more,
the pump stops operation.
Connect the (+) side to (4), and the (–) side to (16).
Not used.
(It corresponds to the pin for inputting the "POWER ON" signal of
the STP-200/300/400 series)
