Pneumatic actuator PAMS NC/NO/DA
12.4 Electro-pneumatic position controller (EPPC)
With the electro-pneumatic position controller (EPPC) for the pneumatic actuator PAMS, the
actuator position or the valve disc position is controlled according to the set position value. The
set value specification is done by an external standard signal 4 to 20 mA or via AS interface.

For further information please refer to the operating instructions "Digital
electro-pneumatic position controller type 8694".

12.5 Electro-pneumatic process controller (EPPC/PR)
With an electro-pneumatic process controller (EPS/PR) for the pneumatic actuator PAMS, the
actual value of the process factor is directly applied to the device as a 4-20 mA signal. The pro-
cess controller calculates the set value for the position controller by a set/actual value compari-
son.
