4.3 Testing the valves and the valve/actuator combination
Note
Before commissioning the MPA-S valve terminal, observe the specifications concerning
the medium ( section 3.6.1 “Pilot control (pilot air supply)”).
The MPA-S valve terminal should be commissioned as follows:
Commissioning variants Activity
Preliminary test of the pneumatic tubing connec-
tion
Checking the valve-actuator combination through
manual override
Complete commissioning of the complete system Installing and connecting the overall system.
Program control via PLC/industrial PC.
Tab. 4.3 Commissioning variants
Commissioning the pneumatics by means of the manual override is described below.
Commissioning of the CPX terminal is described in the corresponding description for the
CPX bus node ( the system description of your CPX terminal, table “Descriptions of the
CPX terminal”).
Warning
Before operating the manual override:
Uncontrolled actuation of solenoid coils can cause the actuators to perform accidental
movements, which may cause personal injury and material damage.
• Disconnect the operating power supply for the solenoid coils from the correspond-
ing connections of the MPA-S valve terminal.
This prevents accidental actuation of the solenoid coils.
Before switching on the operating voltage:
During commissioning, manual override functions which are activated can cause actuat-
ors to perform accidental movements, which can cause injury to people and material
damage.
• Make sure that all manual overrides are reset to their initial position.
You will thereby avoid undefined switching states of the valves.
Proceed as follows:
Warning
Before testing the valve/actuator combination:
• Make sure that nobody is in the danger zone.
