ERROR MESSAGES
A number of error messages can be displayed at the top of the FCO770 Status window in the
event of a system or hardware failure.
MESSAGE:
LEAK ZERO FAULT
Indicates that the zero output of the leak transducer is beyond the automatic zero limits. The

contact your supplier.
MESSAGE:
PR. ZERO FAULT
Indicates that the zero output of the pressure transducer is beyond the allowable 7.5% limit

transducer assembly requires re-zeroing; if this is beyond adjustment look for damage or
contact your supplier.
