'STAY PUT' FUNCTION CONFIGURATION

With input signal 4-20 mA, it is possible to configure a failsafe position in case of loss of input signal.
In standard, the function is active, and the actuator stays in position in case of loss of input signal.
Switches 5, 6 and 8
Move switch 5 to position B for actuator to ope
Move switch 6 to position B for actuator to close in case of loss of input signal.
Move switch 8 to position B to disactivate the '
Caution: in case of input signal 0-20 mA or 0-10 V, the 'stay put' function cannot be used

One can simulate an input signal 4-20 mA locally to c
local/off/remote selector must be on the remote position.
Move local control switch to position 0%, MAN or 100%. Turn potentiometer MAN to simulate an
