Fail Safe Function

This function is available only if requested on order. It allows configuring the action of the actuator in
case of loss of the BUS signal. The action takes place only if the local selector is in REMOTE and if BUS
is operating. When the BUS signal restores, also the actuator restores at its normal functioning.
The fail safe function can be configured via either BUS or local operator interface.
The hardwired controls ESD and INTERLOCKS override the Fail Safe action according to the following
diagram (the hardwired controls INTERLOCKS are available only if optional modules APTM/APTM1 or
PSM/PSM1 are present.
