6 Maintenance
No maintenance measures are required during normal operation.
If a device or module fails, it must be replaced with a faultless device or module of the
same type or with an approved replacement model.
Only the manufacturer is authorized to repair the device/module.
6.1 Faults
Refer to Chapter 3.1.1.1, for more information on the fault reaction of digital inputs.
Refer to Chapter 3.1.3.1, for more information on the fault reaction of digital outputs.
6.1.1 Operating
System
Version 6.42 and Beyond
If the test harnesses detect faults in the processor system, the remote I/O enters the
STOP_INVALID state and is restarted (RUN state) by the associated controller. If a further
internal fault occurs within the first minute after start-up, the device enters the
STOP_INVALID state and will remain in this state. This means that the input signals are no
longer processed by the device and the outputs switch to the de-energized, safe state. The
evaluation of diagnostics provides information on the fault cause.
6.1.2 Operating
System
Versions Prior to 6.42
If the test harnesses detect faults in the processor system, the module automatically enters
the ERROR STOP state and will remain in this state. This means that the input signals are
no longer processed by the device and the outputs switch to the de-energized, safe state.
The evaluation of diagnostics provides information on the fault cause.
6.2 Maintenance
Measures
The following measures are required for the processor module:
Loading the operating system, if a new version is required
Executing the proof test
6.2.1
Loading the Operating System
HIMA is continuously improving the operating system of the devices. HIMA recommends to
use system downtimes to load a current version of the operating system into the devices.
Refer to the release list to check the consequences of the new operation system version on
the system!
Load the operating system using the programming tool.
Prior to loading the operating system, the device must be in STOP (displayed in the
programming tool). Otherwise, stop the device.
For more information, refer to the programming tool documentation.
6.2.2 Proof
Test
Test the HIMatrix devices and modules every 10 years. For more information, refer to the
Safety Manual (HI 800 003 E).
