5-2
This chapter describes routine maintenance, replacement and installation procedures necessary
to maintain the operation of an Advant Controller 450.
Always follow the instructions below when installing and operating an Advant Controller
system to minimize the risks of injury to personnel and damage to the equipment. Local
statutory regulations, to the degree that they are stricter than the following, take precedence.
Observe the following:
•
Use only approved hoisting equipment when lifting cabinets. See lifting instructions
enclosed with the cabinet.
•
Never switch on the voltage supply of the cabinet during installation work. However
replacement of modules in subracks can be done on line, that is while power supply is
switched on. Special instructions are given for the work with power supply units.
•
Power supply units in a "live" system, i.e while the mains supply is switched on, is to be
replaced by authorized service personnel only.
•
Work with care when supply voltage is applied in the system. The voltage in the
cabinet can cause injury and can even kill a human being.
•
Make sure that everyone working on the installation knows the location of the safety
switch and the mains power supply switch to the Advant Controller 450 equipment and
how to use it.
•
When the subsections of the process are checked and a test run has been performed,
a responsible person is to check out interlocking chains, and so on.
•
Inform all assembly personnel about test runs to be performed.
•
Process technicians are to be present when testing and operating the process objects.
•
Never press the system ENTER (initialization) if you do not know what happens in the
system with an initialization. The command RECONFIG is equivalent to an ENTER in the
CLEAR mode.
•
Remember that the control system can be controlled from an engineering station connected
at another node via a MasterNet. For example it can be stopped, configured and started
remotely.
•
Remember that an Advant Controller 450 starts automatically when voltage is applied if
this is not prevented by means of the data base element START. You can also prevent start-
up of an Advant Controller 450 by setting the START MODE selector in the STOP
position.
