Processor Reset

This fault can occur when the Service DIP Switches are left in the wrong position. This
frequently occurs when people have downloaded new firmware. The correct positions should
be SEL0 and SEL1 to on, and Enable Firmware Download to off.
The fault indication for Processor Reset cannot be disabled, neither in the configuration nor
with the dipswitch Supervision at the back of the Controller.
8.12

USB port not connected

This error message can occur when the Configuration Software is just installed. Although
there is no such instruction displayed during installation it is recommended that your PC is
rebooted after installing the Configuration Software.
This problem could also occur when the Service DIP Switches are in the wrong position. A
more common problem in such a case is a Processor Reset Fault. However if fault supervision
is disabled this fault indication will not occur and USB port not connected could occur. Please
refer to the section Processor Reset for more information.
8.13

Data fault during configuration upload

This fault occurs when the Configuration Software you are using and the Firmware on the
Controller to which you are uploading have a different incompatible version.
8.14

A click sounds through the loudspeakers at regular intervals

In a very silent environment like meeting rooms and offices, especially when they are
abandoned, a small click can be heard at the start and end of an impedance measurement.
This click is simply caused by the 20 kHz pilot tone being switched on and off. The level of the
click is small, but also depends on cable parameters, loudspeaker characteristics and load. If
the click, no matter how weak it is, is unacceptable then end of line supervision using the EOL
board should be considered instead of impedance supervision.
8.15

Password not working

A fault message, like indicated below, occurs when data used by the Configuration Software is
corrupted. It sometime happens after a software upgrade or when different versions of the
Configuration Software have been installed on your PC.
To fix it uninstall all versions of Configuration Software and (only) reinstall the version you will
use.
