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
operations.
By the options of the relative screen, unlike the Operator level, the “Maintenance”
level and the “Engineer” level may:
- Put in Set or Unset the selected relay
- Put in Test/Maintenance and take out of Test/Maintenance the selected
relay
-
SET / UNSET
An user with the MAINTENANCE level cannot UNSET more than 50% of the
system’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.
TEST / EXIT TEST
Will put to TEST mode or take out of the TEST (EXIT TEST) mode the selected
relay. It is possible to put in TEST mode just parts of the system at user level
“Maintenance” or “Engineer”. If more than half of the system selected, a warning
screen will pop-up.
Until the number of relays to put in Test/Maintenance mode does not exceed the
defined limits, the selected items will change the status into TEST.
The relay remains in TEST until the Channel Maintenance Time set for the control
panel by the Configuration software (10-60 minutes) is expired.

The relays in TEST status can be activated and deactivated by the options 2-
ACTIVATE and 4-DEACTIVATE.
The EXIT TEST option takes out of the Test/Maintenance mode the selected relay.
From the Relay list (Fig. 3.8.3), using the up/down arrow keys one may scroll
through the list choosing one of the relay and press ENTER to get into a submenu.
This screen is the same for “Operator” and “Maintenance” level, allowing only to view
the relay configuration details.
