PR electronics 4225 User Manual

38 4225V100-UK
Operation
The 4000 series devices provide multiple features for easy user operation, and to perform efficient troubleshooting.
Monitoring the operational status is easy from either the front LEDs or the PR 4500 communication interface.
Status indicators without PR 4500 communication interface
Power Red / green LED indicates system status
f in Yellow LED indicates an active input
Dig. out 1 Yellow LED indicates that relay 1 is energized / f output
Dig. out 2 (only 4225B) Yellow LED indicates that relay 2 is energized
Power green flashing LED 13 Hz indicates normal operation.
Power green flashing LED 1 Hz indicates configurable input limit error.
Power steady green LED indicates internal error.
Power steady red LED indicates fatal error.
Status, error detection and signal ‘out-of-range’ with PR 4500 communication interface
