JP1 in Processor Fault Notification Position
For additional information on processor fault codes and user-fault routines refer to the following
publications:
• Your programming device’s reference manual
• HHT User Manual, publication 1747-NP002:
• Chapter 28, Troubleshooting Faults
• Chapter 29, Understanding the Fault Routine
IMPORTANT
When using SLC 5/02 processor and later processors, a user-fault routine
cannot be used to clear the major fault bit.
ATTENTION: For 1746-OBP16 and 1746-OVP16 modules, all outputs on the module are
OFF if the fuse blows. For the 1746-OAP12 module, all outputs on the same common as the
blown fuse are OFF. If processor operation is allowed to continue after a blown fuse,
extreme care should be taken to be sure the safety of personnel and guard against
equipment damage.
JP1 is in processor fault
position. Processor is notified
when fuse is blown.
