Supplementary Information - Fitting External LED Indication & Boost Link
Notes on Charging mode selector and boost operation:
With both the charging stage mode selector jumpers fitted
uppermost (M) on (7), the unit will function in the float mode,
providing a constant voltage output (at specified level as
shown on page 1), an increased ‘boost’ voltage can be
manually triggered by linking the Boost Terminals (4). Fitting
both jumpers towards (A) on (7) will put the charger in Auto-
3 Stage mode.
Factory default units are shipped with Jumper (7) fitted
in M position for Float mode, Jumper (8) fitted for 12V
setting (on 6/12V units) and Jumper (9) selected for
240VAC.
Notes:
If no AC is present and the unit is connected to a
battery, then the C/F LED (2) will be illuminated. With AC
present and no battery/load connected the Float LED (2) will
also be illuminated.
All the LED outputs are configured for 2.5VDC LED’s, no
voltage drop down resistor is required.
When using the charger in the Auto 3 Stage mode, either
neither of LED’s should be connected or both the Float and
Boost LED’s must be connected for them to function
correctly, if only 1 of the LED’s are connected they will not
function correctly.
ENSURE CONNECTION OF LED’S IS CORRECT

Manual Mode
Boost LED Terminals (3 & 4) will be used for manual boost mode.
Float LED output will be active under all healthy charging conditions, i.e. AC mains OK and Charger Healthy
Charge Fail LED output will be active under AC mains failure or Charger Failure Conditions.
Auto Mode
Boost LED Terminals (3 & 4) will be used for charging mode.
Boost LED output will be active when in boost mode charging
Float LED output will be active when in float mode charging
Charge Fail LED output will be active under AC mains failure or Charger Failure Conditions.
