• Place the transmitter near the gas meter (either identical with double-
sided adhesive tape or with screw fittings.
In case the transmitter (evaluation/transmission unit) must be screwed
on, then you must press the two notches on the left side of the housing
inward with an appropriate tool, e.g. a screw driver. At the same time, at
this position, you should carefully pull the cover forward.
Do not straighten any component inside the housing; do not touch the
electronics.
When drilling make sure to be careful not to accidentally
damage gas, water pipes or any power supply lines!
The maximal distance between IR sensor and evaluation/transmission
unit is predetermined by the length of the connection cable.
Place the evaluation/transmission unit in the direction of the receiver in
order to achieve a maximal range.
• Connect a power supply unit (12-20V=, max. 500 mA or max. 15VA) to
the evaluation/transmission unit (observe polarity, inner contact
= „+"/plus).
• The green operation control lamp and the red status control lamp flash
briefly with each identified number change at the counter.
At the same time, the signal level changes at the jack socket from 3 V onto
0 V.
• The sensor is ready for operation. It transmits (after an automatic reset
of the internal counter reading and a first initialization message at the
receiver unit) the data packet to the receiver unit every 5 minutes.
The data packet consists of the current total counter readings of the
"ES-4" and the counter result of the last 5 minutes.
