Applying Honeywell 50182539-001 as the memory backup assembly for a C300 PCNT05 controller installation
Honeywell identifies 50182539-001 as the enhanced memory backup or RAM charger assembly used with the C300 PCNT05 generation in Series 8 environments. It should be ordered with the controller version and system release clearly stated so the maintenance team receives the intended assembly.
Confirmed product role
Honeywell product information lists 50182539-001 as the C300 PCNT05 memory backup assembly for Series 8 environments. Honeywell also states that the PCNT05 generation uses the enhanced memory backup module, so the controller identity should be verified before the assembly is ordered.
Compatibility data to record: C300 model, Experion release, controller pair identity, IOTA model, memory-backup revision and installed firmware.
Power-loss recovery should be tested as a system function
After Honeywell 50182539-001 is fitted, use the approved controller procedure to confirm charging status, diagnostics and recovery behavior. Do not perform an uncontrolled cabinet power interruption on an operating process. The test record should show date, controller identity, observed alarms and final healthy status.
