Troubleshooting
Important Claims under the warranty rendered void!
The housing screws of the NAV310 are sealed. Claims under the warranty against SICK AG
will be rendered void if the seals are damaged or the device opened. The housing is only
allowed to be opened by authorised service personnel.
This chapter describes how to identify and rectify errors and malfunctions during the oper-
ation of the NAV310.
8.1
In the event of fault
Cease operation if the cause of the malfunction has not been clearly identified!
Stop the machine/system if you cannot clearly identify or allocate the error and if you can-
not safely rectify the malfunction.
8.2
Monitoring error and malfunction indications
The NAV310 monitors itself in operation:
•
After switching on the supply voltage the NAV310 runs through a self-test prior to initial--
isation (loading the parameter set and initialisation of the device functions); during this
self-test the device checks important hardware components.
•
During operation the NAV310 continuously monitors the function of the rotation of the
scanner head.
•
If the NAV310 detects a device error during the self-test, it indicates this situation using
the LEDs.
