Lamar Technologies Activator 282 - Manual (Page 12)

1) Activator 282 to be verified
2) This requires a battery or resistance load such as a 10 Ω 100 Watt power
resistor. A DC ammeter (0 – 10 Amps) can be connected in series with the
battery and load to verify amperes if desired.
BATTERY LOAD
a) Check that the battery on charge reaches 28 Volts (it will continue to
increase). Approximately 30 minutes after reaching 28 Volts, the yellow
CHARGING LED will go out and the green READY Lamp will illuminate. The
battery voltage will drop. This demonstrates charge cutoff.
b) Load the battery with a resistive load (suggested load is approximately 10
Ohms 150 Watt resistor) until the battery drops to approximately 25.2 Volts.
The READY LED will go out and CHARGING LED lamp will illuminate.
Remove the load and allow the battery to charge until the READY lamp
comes back on.
6.4 VERIFYING CHARGING VOLTAGE THRESHOLDS (MANUAL METHOD)
This procedure is not required but may be performed as desired. The manual method
requires the least equipment but is very labor intensive. A more convenient automated
method is given below.
Tools and materials:
1) Activator 282 to be verified
2) Good Lead-Acid battery for test
3) Calibrated voltmeter
4) (Optional) Power resistor, 5Ω to 20Ω, 150 Watt or greater
5) (Optional, for use with power resistor) Two tip plugs, 0.080” (2mm), Emerson-
Johnson 105-0302-001, Mouser Electronics 530-105-0302-001
