BACS Error: HW Revision / Calibration error
Once all modules are set up correctly and the BACS programmer mode is disabled, the BACS system boots and initializes the modules
according to their configuration.
The result can be observed within the BACS Monitor Screen:
After validating the entire configuration, all modules will jump to "green" - The system will be ready for use.
In some rare cases, however, this system message occurs:
HW Revision Mismatch
On initialization, the BACS Webmanager assumes that the hardware revision for the module coming with ID 1 (The first module) is the
reference for all subsequent modules. The Webmanager compares the hardware revisions with the revision number found at ID 1. If one
of the following modules show different hardware revision, the module is marked accordingly:
BACS modules from different installations can be combined as required. After adjusting the ID of the according module, the module can
be inserted e.g. as a spare part. Different hardware revisions are not allowed - they cannot be combined with each other. If a module
does not fit the BACS system, it must be replaced by a corresponding module with a hardware revision that fits to it. In case of
maintenance works inside larger BACS systems containing several BACS Web Managers, keep an eye on possible compatibility issues
between the individual BACS modules
Note
If ALL modules show this issue on initialization but not the first module, take a look at the module with the hardware ID 1:
It is probably be affected and the following modules use the correct hardware revision.
In this case, exchange the ID 1 with a different ID via the BACS Programmer and repeat the boot process. Normally, all modules should
now have the status green and this one module should be marked accordingly.
If you have just been supplied with a single BACS system, please contact your local dealer: It is possible that this shipment contains a
wrong BACS module.
HW Calibration Mismatch
The second test validates if the modules are calibrated:
First of all: you cannot re-calibrate them manually. The calibration is performed during production at the factory. Because the BACS
Webmanager needs exact values for its reliability, it checks if this calibration has been performed during initializing phase. If a module
does not pass this test, it is not suitable for operation:
Unlike the Mismatch Error revision, the Calibration Mismatch Error is a hardware failure that affects the module itself. Unfortunately, this
issue cannot be fixed by porting module to another BACS system:
In this case, the module must be replaced by a corresponding replacement module.
