VLMS-1010 LED Light Monitor

VLMS-10 (Custom)

Key Features

  • Failure Monitoring of up to 10 individual circuits
  • Self-Calibration stores load characteristics of each circuit
  • Failure Detection for >40% reduction of stored load
  • Optional Pre-Check Function
  • 24VDC Application
  • EMC Approved

Description

The VLMS-10 connects in-line with vehicle lighting circuits to passively monitor up to 10 separate circuits, with a maximum load of 10W each. When the load of a circuit falls below the failure detection threshold, due to a partial failure or an open-circuit, individual outputs provide failure feedback. The VLMS-10 is designed to work with a wide range of LED lights.

Self-Calibration for Failure Detection

During installation, the VLMS-1010 operates a self-calibration cycle where it stores the normal operating load of each monitored circuit – calibration can be repeated at any time. The stored values are used to determine when the circuit load has reduced by 40% or more and a failure has occurred. Alternative failure thresholds can be requested. Under failure conditions, a feedback output becomes active for each affected circuit – this is ideal for controlling a dedicated warning light or buzzer, or for activating an audible message when connected to a V-series Vehicle Multi-Message System (VMMS).

Pre-Check

The VLMS-1010 includes the facility to provide the driver with an operating check for all connected lights. Within the first 5 minutes after power-up, the driver can energise each light circuit to test its operation and the VLMS-10 provides an output signal if all circuits are operating within the failure threshold. This can interface with a VMMS for driver feedback.
