Description of Equipment or Protective System:
The PMA.Vision VIS1Yab-c is designed for the measurement of weight in the hazardous location. The
PMA.Vision contains the processing circuitry and has a touch enable LCD display with backlight facility.
Power and data to the non-hazardous location are provided via the YCO17-Z Ex-Link Converter
(FM15ATEX0035X). All signal outputs to the Ex-Link Converter are in RS232 communications. The
PMA.Vision is housed within non-metallic enclosure. A dedicated potential equalization connection is
provided on both the PMA.Vision and the YCO17-Z Ex-Link Converter. Power and data connections
between the YCO17-Z and the PMA.Vision are made via a multi-conductor CAT6 cable.
