MacBAT 5 – USER GUIDE. Version 1.0
EVC enables several options for gas meter connection. To check the possibilities of connection navigate through menu:
• Go to Main menu by pressing enter
• Navigate to menu Measuring Inputs → Flowmeter
• Press enter on parameter ConfImp and choose the proper option corresponding to the type of used gas meter
Available inputs:
• STOP – counters stopped, mode designed for gas meter replacement or initial configuration doing when the meter is already connected
• LF – Low Frequency input, frequency up to 60Hz, cooperation with Wiegand transmitters
• HF – High Frequency input, frequency up to 5000Hz
• EN – NAMUR Encoder input – digital communication with gas meter
• SCR – SCR absolute encoder input
Principles:
• Single position like LF1 means only this one input is used for increasing Vm counter, no control input
• Two positions such as HF1/HF2 mean first input is used for increasing Vm counter, second one is used for control counter V2
• Two positions such as D-LF1/LF2 and D-HF1/HF2 mean the volume is increasing or decreasing depending on the flow direction
Please note HF pulse inputs will work only when EVC is connected to external power supply source. Battery powered
EVC can supply only LF and SCR input.
