instructions
7.1 Faults in automatic mode
7.2 Troubleshooting
If a fault occurs, proceed as follows:
●
Similar as during maintenance work, troubleshooting can be carried out from outside the protec-
tive enclosure or within the protective enclosure with the power supply switched off or from
within the protective enclosure when automatic mode is deactivated.
If troubleshooting has to be carried out from within the protective enclosure then set the [MODE]
switch of the control unit to "MANUAL" and the [Enable/Disable] switch of the Teaching Box to
"Enable".
●
If a robot alarm occurs then first check the error code number or the error status. Take a note of
this useful troubleshooting information and read the appropriate section in the operating and
programming instructions.
●
If the robot itself is affected and it is not possible for the user to remedy the cause of the error/
fault then you must immediately contact your MITSUBISHI sales agent.
P
DANGER:
● Operation must be stopped immediately if you observe slight deviations when operating the
robot or the auxiliary equipment. If immediate shutdown would result in concomitant dan-
gers and hazards, then you must select a suitable time.
●
If the robot stops for no apparent reason when in automatic mode then the operator must never
approach the robot. If the robot nevertheless needs to be accessed, then the EMERGENCY
-STOP
function must be previously triggered or the power supply must be switched off. Make sure
than no new angers/hazards can arise from switching off the power supply.
● If a program is restarted after a reset, you must make sure that from the very start of running
this program no dangerous/hazardous states can aries from the auxiliary equipment (e.g.
check of position on restart, necessity to initialise the auxiliary equipment, etc.)
● If a program has been changed after a cancellation then it must be tested at least once before
restarting of automatic mode is permitted.
