Sub Menu 11 Current Limit Set up
This sub menu is used to set the Charger and Battery Current limits.
Note: This menu is password protected. Adjustment should only be made in consultation with
Magellan Powertronics.
6.1 User Adjustable Set Point instructions.
The following procedure should be employed when adjusting any set point.
1) Select the required set point from the programmable set point descriptions in
Section 6.0 of this manual.
2) Follow the instructions contained in the User adjustable set point instructions
flow chart on page 24 of this manual.
3) Once the set point has been adjusted and programming mode exited, it is a
good idea to check the float and boost settings to ensure they have not been
accidentally changed during set point adjustment.
This should be done with a separate multimeter connected across the battery
terminals.
6.2 Earth Fault alarm
The Earth Fault alarm level is factory set and can not be adjusted.
Ensure that the earth fault alarm is not inhibited by the Micro-controller Board. Connect an
adjustable resistor in series with a multimeter capable of reading 0 to 50mA. Place the
resistor/meter from earth to the charger output (+Ve). Adjust the resistor to obtain the
required earth fault current reading on the multimeter. Observe that the Earth Fault LED (D14
on the Interface board) comes On. Recheck the setting when the resistor/meter is connected
from earth to charger (-Ve).
To inhibit this alarm, set the Earth Fault Inhibit set-point to ON in the Sub Menu 5, Latches
and Inhibit Settings.
6.3 Menu.
(See User Adjustable Set-point Flowchart on the following page.)
• All text following the “=” sign is the current Setpoint.
• When Lead Acid battery type is selected a new menu opens that allows the
temperature compensation factor to be adjusted.
