E1047 SPEED SWITCH UNIT
Cross Reference LS – 20 – A (3177)
To meet recent legislation, we have designed and developed a Unit capable of Automatically Switching most Vehicle Accessories Off at a given speed.
For instance, one of the most popular applications for this is to Switch Off Flashing Beacons or Reversing Cameras when the Vehicle exceeds a given speed.
However the Unit could be used to suit your particular application or to warn the Driver that the Vehicle has reached a given speed.
The switching off speed is set by selecting a combination of up to
6 switches, giving 64 options between the limits of 2.5km/h (1.6mph) and 102.5km/h
The switching off speed can be Factory set or adjusted during installation.
The output on this unit is normally on and switches off at the set speed, it is capable
of switching 10A.
The tri state Override input can control the output as follows:
Switch to positive = output off
Switch to ground = output on
Note: Pin 1 and Pin 6 should be wired directly to the appropriate Pins on the Tachograph
For example on the DTCO 1381 Tachograph:
· Pin 1 of Speed Switch to Tachograph Plug B Pin B8
· Pin 6 of Speed Switch to Tachograph Plug A Pin A6
