Activation of relays:
Each relay can be activated on one or several following conditions:
•
Alarm
•
Fault
•
Inhibition
Factory setting:
•
Relay 1: normally open (not energized) activated on alarm levels
•
Relay 2: normally closed (energised) activated by any fault or inhibition
This menu allows you to switch the format of the output current between 4-20 mA and 0-22
mA.
6.8.5. [INH]ibition submenu
Maintenance inhibition can be configured in « frozen » mode (Factory setting) or « free »
mode.
•
In « frozen» mode, the outputs (current and relay) remain in their previous state.
For example, if the device displays a fault (2.0 mA), it will remain in this mode during
the inhibition
•
If the device is configured in « free » mode, the current output will remain at the
same level than the permanent inhibition
6.9. Maintenance menu [MAIN]
The maintenance menu allows the user to check if the detector is in normal operation
conditions
•
(Test of the relay and current outputs).
6.9.1. [TEST] sub-menu
6.9.1.1. Relay menu
This menu gives access to activation or deactivation of the relays.
The detector switches to inhibition mode. The detector will stay in inhibition mode if the user
goes back through the steps to the main menu. Otherwise, the detector will return to its
“current” state.
6.9.1.2. The 4-20 mA screen
This menu allows the output current to be set at a chosen value. The possible output values
are: 2mA, 4mA, 8mA, 12mA, 16mA, 20mA or 22mA.
During this phase, the detector switches automatically to inhibition mode. The detector will
stay in inhibition mode if the user goes back through the steps to the main menu. Otherwise,
the detector will return to its “current” state.
6.9.2. NETWORK sub-menu
This menu gives direct access to different tests for the network. For any further details,
please refer to the additional network operating manual:
•
SPIN sends the detectors network identification.
•
LIEN switches from normal mode to logic link mode.
•
SWITCH enables the switches to go on mode open/closed/open secured.
