ST MINI 3. Adjusting of actuator Attention! See chapter 1.2. Safety instructions Disconnect the electrical electric actuator from electrical power network! Observe safety regulations! EA is by the producer adjusted to parameters according to the nameplate. The adjustment can be performed at a mechanically and electrically connected EA. This part describes adjustment of EA to specified parameters in case that any unit of EA is reset. -
Page 16: Adjustment Of Resistant Transmitter
ST MINI 3.3 Adjustment of resistant transmitter The resistant transmitter is in the EA ST used to function as a remote position indicator. Before the resistant transmitter adjustment the position switches have to be adjusted. The potentiometer is not needed to be adjusted, it is able to adjust itself with putting the actuator to the both limit positions in accordance with the stroke specified on the nameplate. - Page 17 ST MINI • Switch the converter′s power supply on. Turn the adjusting trimmer A (Fig. 7) to adjust the output current signal rate measured on the terminals 81-82. • Set the actuator to the position „open“. • Turn the adjusting trimmer B (Fig. 7) to adjust the output current signal rate measured on the terminals 81-82.
