6.2 Setting the actuators during commissioning (cover closed)
For actuation of the actuator during adjustment work in potentially explosive atmospheres (end position
adjustment), an electrical manual override by means of a push-button is provided in the cover (for conditions see
chapter 10.3). To reach the manual override, the screw plugs must be opened. The operating status (status display
LED in the Ex d control housing) is indicated by a sight glass in the cover (see figure 4) (see chapter 10.4).
