optioned
Alarm
 Check expansion option 6
 Check wiring on terminals 5T+, 5T-, 4P- and 4P+
 Probe may require commissioning
127 Aux WL Inputs Detect But Not
Optioned
Mains detected on auxiliary WL inputs
but not optioned
Alarm
 Check expansion option 5
 Check wiring on terminals HAI, 1AI and 2AI
130 Feed Water Servo Position
Error
Servomotor is outside of the
commissioned range
Alarm/Warning –
exp. option 20
 Check wiring on terminals P-, FW and P+
 Check signal cable form the MM to the servomotor is screened at one end
 Check that the servomotor is zeroed correctly
 Alarm if expansion option 20 is set
