Connect the charger to the
battery, the charger will detect
the
battery’s
voltage
automatically.
(1)
If a voltage of more than 7.5
V is detected, the charger
recognizes battery as 12V
(2)
If a voltage of 7.5V-10.5V is
found, maintenance charge is
activated ( 0.8A pulse charging
until voltage exceeds 10.5V)
(3)
If the voltage doesn’t reach
10.5V within 30minutes, a
battery fault is indicated.

reaches
12.8V
Every 15-20min the
charger will check the
battery voltage. If the
voltage has increased by
0.2V or more the charging
current will remain the
same.
If the voltage has not
increased by 0.2V the
charger will increase the
charging current by 1
Amp. to 2A. The cycle will
be repeated every 15-
20min. and the charging
current can be increased
to 3A or 4A. This charging
cycle will continue until the
battery voltage reaches
the maximum value.

If the voltage falls
below 12V. Battery

(2)
If voltage is 12-
13.2V, charger will

(3)
If the voltage is
more than 13.2V
charger will wait for
the voltage to fall
before starting a
maintenance charge.

Action
Battery polarity reversal symbol
displayed.
Battery clamps reversed
Disconnect & reconnect correctly
Clamp indication and voltage symbols
displayed
Dirty or oxidized battery terminals. Low or
unstable charging current
Clean terminals
No Display
Mains supply not connected
Check socket
Display back light on, display showing
0.0V and clamp symbol.
Battery not connected
Check clamps, replace battery
Output lead fuses should be checked and replaced as necessary (5A blade) in connection with all faults. Also check the fuse in the
mains plug, which should only be replaced with a 3A BS1362 fuse.
Persistent fuse replacement may indicate a fault with the charger or leads. Check these before each use and do not use if worn or
damaged.
