2.4.4 Pressure sensor plate
Depending on the type, the pressure sensor plate monitors
– the operating pressure in channel (1) (type VMPA-FB-PS-1)
– an external processing pressure (type VMPA-FB-PS-P1)
– the pressure in exhaust ducts (3) and (5) (type VMPA-FB-PS-3/5).
Using three LEDs, the pressure sensor indicates whether the applied pressure exceeds, conforms to or
falls below the setpoint value. An additional LED indicates common errors.
The MPA-S valve terminal can be equipped with up to 4 pressure sensor plates.
The limits for pressure monitoring are set through parameterisation. The pressure sensor plate can be
parameterised via the PLC or the Festo Handheld (CPX-MMI).
Mounting of the pressure sensor plate is described in the mounting instructions
VMPA-FB-PS-... .
Information on parameterising the pressure sensor is provided in the MPA-... electronics
description from Festo.
2.4.5 Pneumatic air supply plate
You can supply the valves with operating pressure separately via the pneumatic supply plate. This is
necessary, for example, in the case of valve terminals equipped with several pressure zones or when a
large number of valves on the valve terminal are switched simultaneously to flow.
Mounting of the pneumatic connections is described in section 5.3.7
“Replacing the sub-base, supply plate or MPA-S end plate”.
2.4.6 Electrical air supply plate
You can separately supply the valves with load voltage via the electrical supply plate.
