  Check whether the alarm LED lights constantly. If so, there is a short-circuit to supply voltage in the cable from the central electronic module (CEM).

  If the alarm LED does not light, check the operation of the alarm LED by activating it.

  Click on the symbol for VCT2000 to begin activation.
