6 Maintenance
Defective modules must be replaced with modules of the same type or with approved
replacement models.
When replacing modules, observe the instructions specified in the HIMax system manual
(HI 801 001 E) and HIMax safety manual (HI 801 003 E).
6.1 Maintenance Measures
The following maintenance measures must be implemented for the modules:
▪ Proof testing.
▪ Loading of enhanced operating system versions.
6.1.1 Proof Test
The proof test interval for HIMax modules must be in accordance with the interval required by
the application-specific safety integrity level (SIL). For further details, refer to the safety manual
(HI 801 003 E).
6.1.2 Loading of Enhanced Operating System Versions
As part of product maintenance, HIMA is continuously improving the operating systems of the
modules. HIMA recommends using system downtimes to load current versions of the operating
system into the modules.
The operating system versions are displayed in the SILworX Control Panel. The type labels
show the operating system versions at the time of delivery.
Before loading operating systems into the modules, check the system compatibilities and
restrictions of the operating system versions. To this end, use the applicable release notes. Use
SILworX to load the operating systems into the modules and ensure that these are in the STOP
state.
