DIGITAL AXLE COUNTER SSDAC-G36 Sl.No : 1 A typical print format is shown below; that can be customized as per customer requirements.

Scheme

� The timing starts with detection of first axle and continues till the event is complete whereby wheel count becomes ‘000’, either by forward clearing or reverse clearing

� An automated printout aids in report generation without any front-end operation

� Timing of any event is not displayed anywhere to avoid preempting

� Once a printout is obtained, the print details gets erased

� To take care of emergency situations of paper out / paper jam etc., a maximum of 20 events are stored temporarily, for taking printouts later

� The data of event-logger can be used for further scrutiny and analysis
