ELCORplus indexer
–The integrated mechanical indexer is equipped with optical sensors
with the detection of the direction of rotation of the meter. The terminals of these sensors
are connected to the SLOT 0 terminals by the manufacturer. The module of the
mechanical indexer interface is fitted in the SLOT 0 position.
Gas Meters with HF Pulse Output
ELCOR –
HF gas meter cannot be used.
ELCOR
plus
– To connect the device, the EXT1 or EXT1/HF module must be installed in
the SLOT 0 position. The EXT1 (EXT1/HF) module allows for connecting either one HF
gas meter with the detection of rotation direction or two HF gas meters. The meter is
connected by means of terminals 1 and 2; to terminals 5 and 6, either auxiliary gas meter
sensor with the detection of rotation direction or another HF gas meter can be connected.
WARNING
When using a HF meter, the corrector must be powered from an external
intrinsically safe power supply (e.g. PS-E, PS-E/A).
Gas Meter with NAMUR or SCR Encoder
ELCOR, ELCOR
plus
– The module of the interface of the encoder must be fitted in the
SLOT 0 position. The gas meter is connected to terminals 1 and 2. The external power
supply of the corrector is not necessary.
