3.5 Adjusting
Parameters
All equipment is shipped from the factory fully checked and adjusted based on the customer order. Do not
make any adjustments unless the equipment has been powered-up and the settings have been determined to
be incorrect. If the settings have been determined to be incorrect, adjustments may be made as detailed below.
3.5.1 Customer Calibration Mode
In Customer Calibration Mode the customer can access and change various parameters used by the A75D(E).
To access the Customer Calibration Mode, press both the
(UP) and
(MODE) buttons (press the
button first - the LCD display should change, hold it down and then press the
button) for about 5 seconds
after “Customer Calibration Mode” appears on the LCD display release both buttons.
Once in calibration mode the customer can raise and lower values with the
and
buttons, and advance to
the next feature with the
button. After the last feature is passed the settings will automatically be saved.
If a feature is accidentally passed over the customer must advance through the remaining features and restart
calibration from the beginning. The calibration features are listed in order below with a brief description and
default values.
Low Voltage Alarm
This setting changes the voltage limit that causes the Low DC Voltage Alarm to activate. The default setting is
1.98 V/C (for Lead Acid batteries) based on the number of battery cells that the unit was designed for. The
number and type of cells is listed on the charger’s nameplate.
(EX: A unit designed for 24L has a default Low
Voltage alarm setting of 47.5)
