Solenoid Valve" Control Function - Siemens SIMOCODE pro System Manual

4.2.13

"Solenoid valve" control function

Description
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
Notice
The motor protection functions are not active. A current measuring module
is not necessary.
Notice
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")
