Verification of output is the only check that is required on an annual basis.
Voltage test points are provided on the unit and verification can be accomplished
with a calibrated voltmeter such as the Fluke 77 / AN.
If the Activator 282 supplies the correct voltage, the required charge current will
automatically follow, and charge amperes are a consequence of the charger and
battery voltage. Charge current from the Activator 282 is not adjustable, and is
automatically limited to the capacity of the Activator 282: 10 Amp pulses for a low
battery voltage, and 2 ~ 5 amp steady state).
6.2 OUTPUT VOLTAGE VERIFICATION AND CALIBRATION PROCEDURE
Tools and materials:
1) Activator 282 to be verified.
2) Calibrated voltmeter with 0.080” (2mm) tip probes.
3) Fine-tipped (1/16”) flat blade screwdriver
Procedure:
a) It does not matter if the Activator 282 is connected to a battery. It does not
matter if the Activator 282 is set for a Lead Acid or NiCad battery.
b) Connect a calibrated voltmeter to the red (+) and black (-) tip jacks on the
Activator 282.
c) Turn on the Activator 282 and observe both its displayed voltage and the
voltmeter voltage. This should be between 28 and 35 Volts.
d) The Activator 282 must agree with the voltmeter within ± 0.3 Volts. If not,
locate the adjustment hole on top of the Activator 282, at the fan outlet and
near the most significant digit of the voltmeter display. Adjust the control with
a fine-tipped blade screwdriver to bring the indicated voltage into agreement
with the external calibrated voltmeter.
