5.2 Fitting/removing components in valve locations
Please note
The double-solenoid valve (Ident.code J) consists of two
components: the control valve and the work valve. Each
sits in its own valve plate. The control valve is marked on
the front with j 12, has no work connections and sits to the
left of the work valve. The work valve is marked with Ident.
code J.
Warning
Switch off the following power supplies before undertaking
installation and/or maintenance work:
•
the compressed air supply,
•
the power supply for the valve solenoid coils.
You can thereby avoid:
– uncontrolled movements of loose tubing
– unexpected movements of the connected actuators
– non-defined switching states of the electronic compo-
nents.
Components in valve locations can be exchanged easily with-
out much trouble.
Proceed as follows:
Preparing the CPV-SC valve terminal
1. Loosen the multipin plug and disconnect it carefully.
2. Loosen the tubing at work connections 2 and 4 of the
valve sub-base to be replaced (see section 3.2 “General
connection methods”).
3. Loosen the wall fastening on the right-hand end plate.
