"Solenoid valve" control function

With this control function, SIMOCODE pro can activate a solenoid valve.

The solenoid valve is brought into the corresponding end position using the

control commands "OPEN" and "CLOSE". SIMOCODE pro must be informed

via corresponding limit switches (OPEN, CLOSED) when the end position

has been reached.

Control commands

• OPEN: Start with "ON >" activates the QE1 contactor control.

• CLOSE: Start with "OFF" deactivates the QE1 contactor control.

The control commands can be issued to SIMOCODE pro from arbitrary

control stations (see also the description of "control stations"). Thus, the

inputs (plugs) must be connected to the corresponding sockets, preferably

to the "Enabled control command" sockets.

Every fault message causes the QE1 contactor control to be deactivated

and puts the solenoid valve into the "CLOSED" position.

Safety guidelines

The motor protection functions are not active. A current measuring module

is not necessary.

If both limit switches respond at the same time (FO=1 and FC=1), the

solenoid valve is immediately switched OFF via the fault message "Trip -

Double 1" (= "CLOSED")

If the end position feedback is different to the control command, the

solenoid valve is immediately switched OFF via the fault message "Trip - End

position" (= "CLOSED")
