This article details the SpeedCheck Manager settings when configuring an advisory sign with Slow Down message only.

Product applicability

The following products are discussed in this article:

  • SpeedCheck: SPEEDCHECK-15 and SPEEDCHECK-18

With the advisory sign and Slow Down options

The following SpeedCheck Manager settings should be used to configure your advisory sign accordingly to display the Slow Down message only after a specific speed has been met or exceeded:

  • System type set to Advisory Speed (this is factory programmed by Carmanah)
  • Operating Mode set to Continuous or Use Scheduler, depending on application
  • SLOW DOWN Message enabled under the Device Setup tab
  • Speed Limit = 0 (this will disable displaying vehicle speeds)
  • Violation Alert = speed at which you want SLOW DOWN to flash or set to 199 for no flashing of SLOW DOWN
  • SLOW DOWN Speed = speed at which you want SLOW DOWN to come on solid 

For example:

  • Sign will be blank until vehicles reach 25 MPH (or KPH)
  • Between 25 - 29 MPH SLOW DOWN will be on solid
  • Once speeds reach 30+ MPH SLOW DOWN will start flashing
