17.2 Other Issues

17.2.1 Modules Reporting a Fault
If the system detects a module fault, the fault will be reported on the screen and the module's LED will change colour to
orange.
If the fault is transient in nature – possibly due to low power supply voltage or to ring communication problems – the module
will return automatically to normal operation when the fault is cleared.
When the system detects a module fault, that module will be set to a safe state. If this happens, the module stops
communicating on the ring and takes its inputs / outputs to the defined 'safe' state e.g. it turns off mV bead current and takes
relays to a power-off state. See Ch.19 Ring Communication Errors for further information.
A failed module will generate ring fault reports, module fault reports and channel fault reports. The channels either side of it
will also report lost communications, but will not be shown as faulty. See Ch19.4 Ring Fault Diagnostics and Debugging
Techniques for further information.
The module should only be replaced if the fault is not due to low power or a ring problem in another part of the system.
Contact your local service representative for help if required.
Note: it may be possible to restore module operation by physically removing and refitting the module to disrupt its power
supply. However, you should contact your service representative for advice as the recovery may only be temporary.

Close Task Manager and relaunch your browser.
Verify that the TPPR has a valid Webserver licence.
Check TCP/IP settings, check if the PC network adapter
is enabled, check proper cable connections. The
Ethernet port of the Touchpoint Pro Control Module
should be connected to a network. Please refer to
Ch.5.2 Cabling Requirements for further information.
If possible, check the TPPR Touchscreen for any
instruction or detailed error message.
A system operation such as power up, backup or restore
may be in progress. Allow time for completion and retry.
Reduce the number of web clients to five or below.
