Installation Of The Securing The Transmitter; Installation Of The Transmitter - Dräger VarioGard IR EX Instructions For Use Manual

Installation of the Transmitter

The system may only be installed by properly trained personnel.
Select the installation location of the transmitter according to the applicable
regulations so that any gas escaping in the area to be monitored is detected
reliably and in good time.
– Select the correct installation location to ensure maximum protection. No
obstacles should prevent the free circulation of air around the transmitter.
– The installation location of the transmitter should be selected so that it is
as near as possible to potential gas leaks.
•
In order to monitor for gases and vapors with a density greater than
air (e.g. NONANE ), the transmitter should be mounted as near as
possible to the floor.
•
Take local air circulation behavior into account. Mount the transmitter
in a location at which the highest concentrations of gas can be
expected.
•
In the case of large rooms, it may be necessary to install several
transmitters.
Securing the Transmitter
1. Remove the covering strips (1) from the cover.
2. Remove the four screws (2) from the upper
housing and remove the cover.
3. Secure with four screws (3) through the housing
(refer to Page 15 for the drill hole template).
When installing on uneven surfaces, prevent distortion of the housing.
The VarioGard transmitter contains a sensitive optical sensor.
Strong mechanical distortions of the housing could impair its measuring
accuracy.
