2.4.4 Pressure sensor plate
Depending on the type, the pressure se nsor plate monitors
– the operating pressure in channel (1) (type VMPA-FB-PS-1)
– an external processing pressure (type VM PA-FB-PS-P1)
– the pressure in exhaust ducts (3) a nd (5) (type VMPA -FB-PS-3/5).
Using three LEDs, the pressure se nsor 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 t he case of valve terminals equippe d with several pressure zones or when a
large number of valves on the valve terminal are switch ed 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 su pply plate
You can separately supply the valves with load voltage via the electrical supply plate.
