HI 800 101 HIMatrix Engineering Manual
Note
Plug connectors must never be reversed or inserted incorrectly.
To prevent errors the I/O plug connectors of the HIMatrix systems
are numbered sequentially and connectors for the power supply
are labeled with L+/L-.
Note
Make sure that the wires have the required cross sections.
8.3 Replacement of Modules
A module in the F60 can only be replaced with the power switched off, i.e. the relevant sys-
tem components must be shut down.
The replacement of an existing or installation of a new module is described in the chapter
Handling modules in the HIMatrix System Manual Modular System F60.
The positions of the DIP switches must be noted with the analog output module AO 8 01 in
the F60. They can be used to configure every channel as voltage or current output (see the
module datasheet for more information).
8.4 Maintenance
The HIMatrix systems are designed for industrial operation. All HIMatrix components have a
very high availability and comply with the requirements of IEC 61508 for PFD and PFH in
accordance to SIL 3. For more information see the HIMatrix Safety Manual.
With relay modules the maximum number of operating cycles in accordance to the specifica-
tions must be noted. They must be tested at the specified test intervals.
Note
For all safety-related uses the modules must be generally over-
hauled in periodical time intervals (Off-line Proof Test every 3
years for relay output modules, every 10 years for other modules,
see IEC/EN 61508-4, paragraph 3.8.5).
8.5 Replacement of Back-up Batteries
The HIMatrix devices with hardware revision 01 (see type label at the back) have a back-up
battery to save data in the event of failure of the 24 VDC power supply. The back-up battery
must be replaced every four years. In all actual HIMatrix devices with hardware revision 02 a
goldcap is integrated.
The relevant system manual contains a description of the replacement procedure.
A change of the buffer battery must only be executed by the
HIMA service. If the customer opens the device this will nul-
lify the guarantee and the certification.
Only personnel familiar with ESD protection precautions is qualified to replace back-up bat-
teries.
