Product description
LAG-14 ER
11
Probe
The black LAG container is installed above the interstitial space. The
bottom side of the black LAG container is connected to the top of the
interstitial space via a hose. This way, the black LAG container is the
top part of the interstitial space. The interstitial space is filled with
leak detection fluid to the middle of the black LAG container. The
probe is installed from the top of the black LAG container so that the
electrode tips are covered by the leak detection fluid. Both electrodes
are connected to the control unit by a two-wire cable.
Control unit
The control unit continuously monitors the electrical resistance be-
tween the two electrodes of the probe. The green pilot lamp lights up
when the device is ready for operation. If the probe resistance is less
than 5 k
Ω
, there is no alarm condition: The red alarm lamp is off, the
relay is:
•
De-energised (in the operating mode Eco)
•
Energised (in the operating mode FailSafe)
If the resistance is greater than 5 k
Ω
, an alarm condition, i.e. a leak
has been detected by the control unit: The red alarm lamp and the
audible alarm are on and the relay is:
•
Energised (in the operating mode Eco)
•
De-energised (in the operating mode FailSafe)
The audible alarm can be muted with the "Acknowledge" button in
the case of an alarm.
No alarm is triggered in case of a power outage. When mains voltage
is restored, the product immediately resumes operation. If a leak has
occurred in the meantime, this is signalled.
The green pilot lamp lights up as soon as the leak detector is sup-
plied with mains voltage. The Test button allows you to simulate an
alarm condition in order to perform a function test.
