Operation with I/O &
safety string checkout
performed 1. Check EPNP. It should be active for normal power. Can prevent Up runs depending on E10
value.
2. Check PRSW. It should be active for normal conditions, and will prevent Down runs.
3. Check OLTO. It should be active for normal conditions, and will prevent UP runs.
• 1074 fault is issued for inactive PRSW input.
• 1019 fault is issued after a run attempt with OLTO inactive.
4. Verify that the appropriate INCTx inputs activate from the inspection button activation.
5. Troubleshoot the inspection station wiring per the job prints.
Safety Processor (SP)
bad LED • The SP monitors the safety critical inputs of the elevator system using safety nodes.
• The SP monitors inputs for these functions: Door State, Door Bypassing, Inspection Opera-
tion (including Hoistway Access), Terminal Speed Reduction, and Speed Limit Enforcement.
• All of these except Terminal Speed Reduction are also monitored by the CPU and the PLD.
• In the event a safety node fails, loses communication, or reports an I/O state that disagrees
with another monitoring subsystem, the SP BAD illuminates and faults are logged.
• It is normal for the SP to remove power to the safety string without logging any faults for
conditions that are considered normal operation.
Example: IF/IR/IT/IB and no DCL = An open car door, SP inhibits a run until door is closed
(or bypassed).
