Using the positioner as a position transmitter

The positioner can be used as a position transmitter with three-step control.
1. Disconnect the wires leading to the terminals aL and eL.
Î Make sure that the disconnected wires are properly insulated (e.g. by using installation
clamps).
2. Wire the conductors of the external three-step control signal (controller) to the terminals
aL, eL, and 81 (the terminals 11, 12, and 13 as well as the priority circuit at terminals 82
and 83 do not function as a result).
