push the piston and during this trial this alarm
message is displayed.
√ 45 Filter 1 Index Forward Att. #45
The Index piston is not locked after a backward
command. The controller performs a second trial to
push the piston and during this trial this alarm
message is displayed.
√ 46 Filter 1 Piston Movement SW2 to SW1 #46 The main piston started to move from SW2 to SW1
but the movement is not completed. This fault
message is issued only after an unsuccessful second
trial to push the piston by the controller. This is a
fault status of the specific filter, since the other
filter is still operational the system issues only an
alarm message.
The following table lists and describes the possible system fault messages that may appear on the controller’s status
screens.
