5.3.4 Signal range at the analogue output 1: view/edit
If the actuator is equipped with a position transmitter (potentiometer, RWG
or MWG), an analogue position feedback (galvanically isolated) is available
as a 0/4 – 20 mA signal at the electrical connection (see wiring diagram). An
adjustment to the end positions or the defined travel is not required. An
automatic adjustment is done via the end positions (LSC (WSR) and LSO
(WOEL)).
For torque seating, the end positions OPEN and CLOSED of the limit
switching should be set as close as possible to the end positions of the
valve to minimise the deviation of the feedback.
TORQUE E6
Analogue torque feedback signal (analogue output 1 assigned to torque signal).
If a magnetic limit and torque transmitter (MWG) is installed, an analogue
torque feedback (galvanically isolated) is available as a 0/4 – 20 mA signal
at the electrical connection (refer to wiring diagram). The zero point is in the
centre of the selected output range (at 10 mA or 12 mA). The torque in
direction CLOSE is indicated with 0 – 10 mA or 4 – 12 mA, the torque in
direction OPEN with 10 – 20 mA or 12 – 20 mA. For 100 % of the nominal
output torque, 0 or 4 mA is indicated in direction CLOSE, and 20 mA is indi-
cated in direction OPEN.
