MacBAT 5 – USER GUIDE. Version 1.0
Encoder input is designed for establishing uninterruptable communication with gas meter basing on the digital data transmission between
gas meters and volume converters. Transmission is done through periodical sending gas meter counter absolute state. Volume converter
saves the value obtained from encoder to Vo counter and transfers it to Vm counter. It is required to follow certain steps in order to configure
properly the input.
Properly configured gas meter equipped with encoder should have synchronized counter between MacBAT 5 – in the
meaning of counter Vo – value read from encoder.
When primary gas volume input is set to EN/SCR mode further modifications of Vm counter are not possible
First – prepare the configuration. After setting the configuration connect the Encoder output to volume converter.
Opposite way of work may cause in significant undesirable increase of main counter.
Configuration procedure:
• Set the ConfImp parameter to STOP
• Set Vm and V2 counters to the ones corresponding to gas meter totalizer.
• Connect the wires responsible for Encoder communication
• Change ConfIimp parameter to EN/SCR
• Wait until the communication will be established
Encoder usage has influence on battery lifetime. By default communication with encoder is set to every 30 seconds
with possibility to reduce this time to 5 seconds. Externally powered device communicates with encoder every 5
seconds.
