6. Commissioning, Functional Check, and Maintenance
Only perform commissioning once the steps in section 5
"Mounting" have been fulfilled.
6.1 Commissioning of the leak indicating unit
(1) Remove bridges from the leak indicating unit channels to be
used.
(2) Establish connection lines between the potential-free relay con-
tacts of the devices to be connected and the respective channels
of the LAE.
(3) Connect the power supply to the leak indicating unit.
Note:
The power supply complies with the requirements described in
chapters 3.3, 5.4, and 5.5 as well as in the relevant documenta-
tion of the connected device.
(4) Check that the "Operation" signal lamp on the leak indicating unit
lights up.
(5) When the signal circuits are correctly closed (via leak detector or
probe/service contacts or bridges), only the "Operation" indicator
lights up.
(6) Determination of the audible alarm for the individual connected
channels. For this purpose, establish the alarm status at the re-
spective connected devices, probes, or service application and
determine the audible and visual alarm signal at the leak indicat-
ing unit.
Acknowledge audible alarm(s) if necessary.
Note:
To set the alarm condition, read the relevant documentation for
the connected device.
(7) If an alarm has been detected in (5), restore the operating status
of the connected devices and check that the respective signal
lamps have gone out on the leak indicating unit (operating status
as in (4)).
Note:
To set up the operating status, read the relevant documentation
for the connected device.
(8) Repeat points (5) and (6) for further occupied channels.
6.2 Functional Check and Maintenance
(1) Once a year as part of the leak detector test.
(2) Observe regulations and information on the test scope according
to the documentation of the connected devices.
