4.3.1 Lamps-Out Calibration for Stand-Alone Mode
In order for the ACE2 to correctly calculate the number of lamps burned-out it has to be calibrated. For best accuracy, the
lamps-out calibration is done only when CCRs are loaded to 75% or more of their specified rating. For best accuracy, all lamps
on the lamp circuit being calibrated have the same wattage rating, otherwise the lamps-out detection is not as accurate on
lamp wattages not used in the calibration process. Some devices on a series circuit such as but not limited to power adapters,
L-858 sign electronics, and L-858 sign fluorescent lamps cause inaccurate lamp-out detection.
In all modes of operation, the calibration is performed in this order;
1. The number of initially present lamps-out is entered in the ACE2
2. The ACE2 steps through all brightness steps and takes measurements.
3. One Lamp is removed from the circuit.
4. The ACE2 steps through all brightness steps again and takes measurements.
5. At this time, it records the Current and Voltage values for each step. If the regulator’s VA drops to 90% of the recorded
value for that step, LOW VA is displayed.
6. Calibration results are confirmed by the operator and stored in the ACE2’s non-volatile memory.
In the stand-alone mode of operation, the lamps-out calibration is performed using the LO Calibration local menu command.
In the L-829 mode, the ACE2 controls the CCR through the brightness steps. For an L-827 application, the operator manually
changes steps using the CCR local controls of brightness setting lines.
When connected to an ADB Airfield Solutions L-890 ALCMS the lamps-out calibration is performed using the vault computer.
