7.1 Introduction
About this Chapter
This chapter details all repair activities recommended for the controller.
It is made up of separate procedures, each detailing a specific repair activity. Each
procedure contains all information required to perform the activity, such as required
tools and items.
Safety Information
Before any work described in this chapter is commenced, it is extremely important
that all information concerning safety is carefully studied.
There are general safety aspects that must be read through, as well as more specific
safety information that describes danger and safety risks when performing the
procedures. Read the Safety Manual before performing any service work.
WARNING!
No repair work must be performed on the robot before the safety
guidelines in the Safety Manual have been read and understood. Work must only be
performed by skilled personnel with the proper training.
Organization of
Procedures
The procedures are divided into a procedure for removal and a procedure for
refitting. At the start of each procedure, a reference list shows information located
other places in the manual than in the procedure. If you want to print out a
procedure, you should also print the information referred to under reference to get
all information you need to perform the repair operation.
The manual describes the type of service work that can be carried out by the
Customer´s own service staff on site. Certain types of work, requiring special
experience or special aids, are not dealt with in the manual. In such cases, the
defective module or component should be replaced on site. The faulty item should
be sent to your local ABB organization for service.
Replacement Items
Make sure that any replacement items are available before performing any repair
procedures. Use only replacement items listed in the spare parts catalogue.
Purge System
During operation, the manipulator is supplied by compressed air (ex-version). For
this reason, the robot can not operate unless all covers are in place and properly
sealed. Missing screws will cause air leaks and result in increased air consumption
or failure in the purge system. This does not apply for non-ex robots.
Tightening Torque
Generally, all screws must be tightened with correct torque, as described under
’Tightening Torques’ on page 216.
