3 Electrical connections Upon installation of the electric ca-bles, you are required to observe theregulations concerning electricalpower installations according to DINVDE 0100 as well as the regulationsof your local power supplier. Establish electrical connections as indicatedon the circuit diagram...

4 Operation and setting 4.1 Manual operation of theactuator To operate the manual override, place4 mm hex wrench on the red actuator shaftlocated at the side of the housing. The hexwrench is delivered with the actuator. It isattached to the bottom of the housing. Manual override is only possible in ...

4.3 Setting the digital positioner In the actuator version with digitalpositioner, the travel is calibrated automati-cally, allowing the travel (controlled variablex) and the input signal (reference variablew) of the positioner to be matched in thebest possible way. Additionally, the digitalposition...

5.1 Limit switches The retrofit kit (order no. 1400-8830 ) is re- quired to install limit switches. If the actuatoris not already equipped with potentiometersor a positioner, the basic unit (order no. 1400-8829 ) is also required. The unit in- cludes the spindle gear (2) and the interme-diate gear (...

5.2 Potentiometers Actuators with a digital positioner cannot beequipped with potentiometers. To install the potentiometers, an actuatorboard with the appropriate potentiometersand gears (12 and 13) is required. If the actuator is not already equipped withlimit switches, the basic unit (order no. 14...

5.3 Digital positioner To install a positioner, a corresponding ac-tuator board and TROVIS-VIEW 3374 andconnecting cable 0450-1978 are necessary. If the actuator is not already equipped withlimit switches, the basic unit (order no. 1400-8829 ) is also required. The unit in- cludes the spindle gear (...

5.3.1 Calibrating the positioner To calibrate the positioner, proceed as de-scribed in section 4 of EB 8331-2 EN. 5.3.2 Simplest method to calibrate the actuator If tools such as the TROVIS-VIEW software,PC etc. are not available for calibration ofthe actuator and the actuator operation withmaximum ...
