Overview:

VDO Sceptron Test and Accessory Tool


Magnetic 'control button'

A magnetic sensor is embedded inside the VDO Sceptron behind the label on the back of the fixture (see C in Figure​​​​​​​​​​​​ 1). The sensor acts as a control button. To activate the sensor, swipe a magnet past it.

We recommend that you use the Martin VDO Sceptron Test and Accessory Tool, PN:  91610139, which contains a magnet.


Activating the magnetic sensor lets you display the product's status, test the LEDs and reset the VDO Sceptron.


Status display

To display a VDO Sceptron fixture's status, swipe the magnet over the sensor once. The first four and last two LEDs on the fixture will give one of the indications listed in the tables below for a few seconds.

​Testing, rebooting and returning to defaults

​The table below lists the functions of the magnetic 'control button' on each VDO Sceptron fixture.
 

Test patterns are stored in onboard memory. This lets you test the LEDs without an external controller, but test patterns can also be called up on P3 system controllers, the P3 PowerPort 1500™ and the P3 PowerPort 1000 IP™.
