Important
Claims under the warranty rendered void!
The housing screws of the NAV245 are sealed. Claims under the warranty against SICK AG
will be rendered void if the seals are damaged or the device is opened. The housing must
only be opened by authorized SICK service personnel.
This chapter describes how to identify and remedy faults in the NAV245.
9.1
Response to faults
9.2
Monitoring error and fault signals
During operation, the NAV245 monitors itself:
•
After the supply voltage has been switched on, the NAV245 runs a self-test before
initialization (loading the parameters and initializing the device functions). During this
test, it checks important hardware components.
•
During operation, the NAV245 constantly monitors whether the scanner head is
functioning, i.e. rotating correctly.
•
If the NAV245 detects a device error during the self-test or operation, it displays this via
the LEDs.
WARNING:
Cease operation if the cause of the malfunction has not been clearly identified.
Immediately take the device out of operation if you cannot clearly identify the fault and
if you cannot safely remedy the problem.
