Adjustments without remote panel
WARNING: Always check with your battery
supplier if the choosen charge characteristic is
suitable for your battery and application
• Remove the frontplate and disconnect battery
and Voltage sense and Temperature sense and
connect a digital voltmeter to – and +1 output.
Bulk-current
• While switching on keep both the pushbuttons ⇑
& ⇓ pushed.
• Release pushbuttons.
• Bulk LED is flashing alternately with Failure LED.
• Push ⇑ for up and ⇓ for down.
• Reading as follows:
Discard first digit of DVM then multiply by 10, i.e:
22.50V => ….2.50 => 25 Amps
15.00V => .....5.00 => 50 Amps
• Switch the charger Off to store.
Absorption and Float voltage
• While switching on keep the pushbutton ⇑
pushed for Absorption voltage and ⇓ for Float-
voltage.
• Release pushbuttons.
• Absorption or Float LED is flashing alternately
with Failure LED.
• Push ⇑ for up and ⇓ for down.
• Reading on voltmeter as is.
• Switch the charger Off to store.
• Please note that in adjust-mode the
Temperature sense compensation is not taken
into account.
Warning: If the charger is not switched Off
after an adjustment the new value will not be
stored but will remain on the outputs. After 4
hours the charger continues the normal
sequence with the old values. This can be
useful if a forced high voltage is wanted to get
some life in an assumed ‘dead’ battery.
Return to factory settings
• Switch the charger on.
• Keep the pushbutton ⇑ and/ or ⇓ pushed while
switching off.
• The factory settings are restored.
When ready
• Connect battery and if applicable Voltage sense
and Temperature sense.
• Replace the frontplate.
