To Enable/Disable the Fault Detection
Note that the factory default for fault detection is ON
Normally the main control unit will perform checks of the electrical system during operation. If a fault
occurs in a particular system, that system (and possibly others) will be shut down. This can make
troubleshooting the system difficult. This option will allow service personnel to disable some of the fault
detection checks to facilitate troubleshooting. This will not disable the over-current protection on any of the
systems. To turn the fault checking on or off:
1 Turn the key switch off.
2 Press and hold both the scrub off switch and solution switch
