Manual Operation; Setting The Actuators During Commissioning (Cover Open) - PS Automation PSF-M-EX Kurz- Betriebsanleitung

3. Manual operation

3.1 Setting the actuators during commissioning (cover open)

When commissioning the actuators, the cover must be opened. The cover may only be opened in non-hazardous
areas and in a dry environment (see chapter 8). For actuation of the actuator during adjustment work (valve
assembly and end position adjustment), an electrical manual override by means of a pushbutton is provided (for
operation, see section 7.3).
Programming of the controls (DIP switch) is possible in the de-energised state (see chapter 7.1). To do this, first
loosen 4 fastening screws of the upper cover of the Ex d control housing, then the upper cover can be removed from
the Ex d control housing. The upper cover of the Ex d control housing must not be damaged in the area of the joint
gap when removing it.
The upper cover of the Ex d control housing must be installed taking into account the position of the push button
and the light guide (see figure 1). The tightening torque for the Ex d cover screws is 6 Nm, minimum quality of the
screws 8.8.
The operating status (status display LED in the Ex d control housing) is indicated by a light guide in the Ex housing
(see chapter 7.4).
The electrical connection of the drives is made via the terminal strip. For this, the wiring diagram must be observed.
