9.8.3 Faults in the Coprocessor and Communication Modules
Faults of the modules are signaled by front LEDs (interface LED or ERR LED). The corre-
sponding function block informs the user program via system variables. In order to maintain
the redundancy of the H41q and H51q systems faulty coprocessor or communication mod-
ules have to be changed immediately. To change faulty modules in a redundant system (two
central modules) during operation of the system the following procedure must be observed:
1. Remove fixing screw of the central module.
2. The related central module has to be removed.
3. Remove fixing screw of the module to be changed.
4. The defective coprocessor module or communication module has to be removed.
5. All interface cables including cable for redundancy have to be unplugged.
6. On the module in exchange for the defective module all switches have to be set exactly to
the same positions.
7. All interface cables including cable for redundancy have to be plugged in.
8. The coprocessor or communication module in exchange has to be plugged in.
9. Fix the mounting screw of the changed module.
10.The related central module has to be plugged in.
11.Fix the mounting screw of the central module.
9.8.4 Repair of Modules
A repair by the user is not possible as the legal regulations for intrinsically safe and safety-re-
lated modules cannot be complied.
Additionally special testing programs are necessary for repairing.
Therefore defective modules should be sent to HIMA for repair with a short fault description
after they have been checked on the customer's premises. The fault description of central
modules and for input and output modules should contain:
– ID no. (total) of the module e.g. at a F 8650E module: 01.064894.022
– measurements to repair up till now,
– detailed fault diagnosis from error state view (refer to the user manual ELOP II and the
user manual ELOP II Resource Type), in case of redundant PES the diagnosis of both
central modules should be included.
The fault description should contain the measurements taken up till now (checking the power
supply, exchange of the module).
9.8.5 HIMA Service, Training and Hotline
Appointments can be made with the Service Department concerning start-up, testing or mo-
difying of the control cabinets, dates as well as the extent of the work to be done.
HIMA makes special trainings based on the current training program for its software programs
and the hardware of the PES. This training usually takes place at HIMA. Please ask for the
training program as well as for the dates of the internal trainings at HIMA.
We also offer training on site on the customer's premises. On request the trainings can be ar-
ranged also as external or special trainings.
