In the main window, close to each channel (detector) its status will appear: TST
(under TEST) or FLT (fault). Now it will be easy to verify, directly in field, which
modules or detectors are not communicating on the RS485 bus and so fix the
issues. When these fault are fixed, the channels status in the main window will
change from FLT to TEST.

Using the up/down arrow keys one may scroll through the list choosing one of
the channel and press 3-Relay for the SET / UNSET and TEST / EXIT TEST oper-
ations. Operator level users are not enabled for the operations described above,
while Maintenance and Engineer users are.
SET / UNSET
Pressing 3-Relay in the Maintenance or the Engineer level it is possible to Set or
Unset parts of the system.
An user with the MAINTENANCE level cannot UNSET more than 50% of the sys-
tem’s channels and relays.
The only exception is the ENGINEER level, which may UNSET the whole system
if necessary. It is required to do so for maintenance operations in the installation
where the gas detection system is installed.
