The YAMS System for clear complete Assessment and Monitoring of Operating Times

Some vehicles as shown at the left, are subject to being fitted with such monitoring system as YAMS is, for the precise assessment of data of the working times for the real costs that had occurred.

Vehicle-mounted units record precise a range of automatic measurements and manual inputs. This collected data provides accurate fleet, grouped or individual vehicle reporting.  The transfer of the data is either manual or automatically send to its office for processing invoicing.  

The YAMS recording system of working data is in fact producing accurate reports of fleet or vehicle activity data based on Windows PC-based software. The produced reports are shown in spreadsheet and graphically format on the monitor and printouts, based Window PC software.

Vibration Recorder VR272

The new recorder is a smaller and more rugged unit that is mounted on any surface that experiences vibrations while working. It is dust- and water-resistant, tamper proof and UV rays protected.

The unit is self-contained, no external connections are required, and all functions are controlled internally. It operates for up to two years using a pair of monobloc 9 Volt batteries.

The data storing capacity is adequate for approx. 228 hours, about four working weeks. 

In a simple, once-off operation Activity Recorders are user-programmed with a unique registration number. This number is stored in the recorders indefinitely and is used to identify data belonging to each vehicle.

Engine operation may optionally also be monitored by connecting the hour meter cable (HR-25), supplied with the Activity Recorder, to the ignition, oil pressure switch or across an existing hour meter.

Vibration Recorder VR272R

The Activity Recorder VR272R is basically the same as the VR272. It has been equipped additionally with a 12-position dial switch on its front panel.

This dial may be user-configured to record work conditions, work categories, breakdowns, different work locations, customers, operators etc. Reports in the system software permit analysis of work-categorised activities.

These units contain a clock/calendar and store the time and date and activity information when any of the following events occur:

  • presence of work vibrations - stored as the average intensity during each minute,
  • changes in the state of an external voltage - used to monitor ignition or engine running time,
  • changes in the position of the 12-position dial - used by the operator to identify the type of work or work code.
