Technical data of product parameters

If there is a faulty central module in A4H124-24TX P0973JM with one central module, this is
usually recognized when the PES switches off.
If there are faults in PES with redundant central modules, the device having no failure takes over the operation without interruption. The diagnosis
display on the functioning central module indicates MONO and the diagnosis display of the faulty central module shows STOP. If you press the A4H124-24TX P0973JM
buttons on the front of the faulty central module, the type numbers of the
possible faults are displayed (refer to the manual “Functions of the Operating Systems”).
When the programming device is connected it serves the possibity to display the errors found. These values are stored in the RAM (memory) of the
PES. These values are important to get a clear analysis of the errors. They
should be safed with “Print” or “Export” (refer to the user manual ELOP II).
Attention has to be paid to correct switch positions and correct version of
the operational system (on the display) if the central module is replaced
(for insertion and withdrawing of modules within the central rack refer to
chapters 7.1.3 and 7.1.4).
If the user program has to be loaded after exchanging the central module
then pay attention that with redundant PES the correct central module will
be loaded. Also pay attention that the code version of the existing and user
program to be load is the same.Faults on safety related input/output modules are recognized automatically by the PES during operation and they are displayed on the diagnosis A4H124-24TX P0973JM
display by I/O error with the indication of the faulty position.
If an input/output module has a line monitoring also the feeding lines to
sensors an actors are checked and faults are indicated on the diagnosis
display additionally with the defective channel number. In this case also
the external wiring has to be checked and the module must not be changed.
The effect of faulty channels of not safety related input/output modules A4H124-24TX P0973JM
will be the difference between the signal status in the logic and of the appertaining LEDs on the cable connector. If the logic signal does not match
the LED display, the respective input/output module must be exchanged.
With output modules you should first check whether the control element
works or whether there is a line break.
Input/output modules can be inserted and pulled out during operation. For
Insertion and withdrawing of input/output modules refer to chapter
