Maintenance
The maintenance of HIMatrix systems is restricted to the following:
Removing disturbances
Replacing the back-up battery, if required.
Loading Operating Systems
9.1
Interferences
Disturbances in the CPU 01 processor system mostly result in the complete shut-down of the
controller and are indicated via the
ERR
LED on the CPU 01.
For possible reasons for the
ERR
LED to light, refer to the CPU 01 manual (HI 800 189 E).
To turn off the indicator, start the
Reboot Resource
command located in the
Extra
menu
associated with the Control Panel. The controller is booted and re-started.
The system automatically detects disturbances in the input and output channels during
operation and displays them via the
FAULT
LED on the front plate of the corresponding module.
Even if the controller is stopped, the PADT diagnostic history can be used to read out detected
faults, provided that communication was not disturbed as well.
Prior to replacing a module, check whether an external line disturbance exists and whether the
corresponding sensor or actuator is ok.
9.2
Replacing Fans
HIMA recommends replacing the fans of the HIMatrix F60 on a regular basis to prevent the fans
to fail:
At normal temperatures (< 40 °C):
every 5 years
At increased temperatures (> 40 °C):
every 3 years
The fans must be replaced by trained personnel.
9.3
Loading Operating Systems
The processor and communication systems have different operating systems that are stored in
the rewritable flash memories and can be replaced, if necessary.
NOTE
Disruption of the safety-related operation!
The controller must be in the STOP state to enable the programming tool to load new
operating systems.
During this time period, the operator must ensure the plant safety, e.g., by taking
organizational measures.
i
The programming tool prevents controllers from loading the operating systems in the RUN
state and reports this as such.
Interruption or incorrect termination of the loading process has the effect that the controller
is no longer functional. However, it is possible to reload operating system.
The operating system for the processor system (processor operating system) must be loaded
before that for the communication system (communication operating system).
Operating systems for controllers differ from those for remote I/Os.
