14. APPENDIX B – Model 190A
Designed for non-legal-for-trade portable axle weighing applications such
as with Cardinal’s CWL-40 and 760 series mobile wheel weighers, the
Model 190A weight indicator features axle weighing software, traffic
control mode to automatically capture accumulative axle weights without
the driver having to leave the truck (when connected to a SB500 remote
display and printer), two RS232 serial ports (for printer and remote
display), optional rechargeable lithium ion battery, capacitive touch keys,
and IP69K-rated wash down enclosure (the highest protection rating
possible). The 190A feature 3 watertight gland connectors, quick-connect
power connector, and one ID.
14.1 Traffic Control
Traffic control is available when the 190A is used with an SB500
scoreboard with traffic light. The SB500 is selected by setting the
Continuous Output format type for the serial port to 2.
After the SB500 has been selected, a prompt for threshold weight will be
displayed tHrS=. If the threshold is set to 0, then traffic control will be
disabled. Otherwise, the threshold weight will determine whether the
traffic light is red or green.
When the scale gross weight is less than or equal to the threshold weight,
the traffic light will be green. When the scale gross weight is larger than
the threshold weight, the traffic light will change to red. The light will stay
red until the scale gross weight is less than or equal to the threshold
weight or a ticket is printed.
If a ticket is printed, the light will change to green. It will remain green until
the scale gross weight goes below and then above the threshold weight
again. Then the light will change to red.
