4.1.3 System Messages and Errors
The devices connected via the analog interface can only report their malfunction by signal under range or over range.
The reason for signal under range usually occurs because of loss of signal do to missing signal from wiring problems.
The following system error messages of the analog interface are detected and recorded:
“AP 0X Overrange” Current signal at analog input > 21.2 mA
Cause: Short-circuit at analog input, analog sensor not calibrated, or defective.
Solution: Check cable to analog sensor, make calibration, replace sensor.
“AP Underrange” Current signal at analog input < 3.0 mA
Cause: Wire break at analog input, analog sensor not calibrated, or defective.
Solution: Check cable to analog sensor, make calibration, replace sensor.
Any device with microprocessor and digital communication - such as digital heads, sensor boards, EP modules and
even the controller - is equipped with extensive self-monitoring systems and diagnostic functions.
They enable detailed conclusions about the error causes and help the installers and operators to quickly determine the
cause, and/or to arrange an exchange.
These errors can only be transmitted when the connection to the central (or tool) is intact.
