BEWATOR COTAG 4101-2 - Troubleshooting System Faults; Initial System Failure Diagnosis

Chapter 19
Fault finding
If you have installed a system and it doesn’t work correctly, follow the
steps in this chapter and you should be able to deduce the reason.
The first section tells you what to check on a system which has never
worked. The section after gives detailed fault finding on all parts of
the system.
System never worked
The fault (in order of likelihood - most likely first) could be in:
• The Controller not being taught its Distributor Code
• the Software configuration
• the wiring
• the communications between Controllers or with the PC
• the antenna (more likely with a loop than a reading head)
• the Controller and reader modules
• the card
Always check the Distributor Code first:
• Every 4101-2 Controller fitted with an RF module must be
taught its Distributor Code.
You cannot get the system to read cards until the comms is working
and you have downloaded data from the Software in the PC to the
Controllers.
Therefore, the next steps to take are:
1. get the comms working.
2. enter a site code into the Software and send it to the
Controllers.
3. enter data into the Software database to configure the cards
and readers.
