User tips when charging a highly discharged battery (no-load voltage <10.5 V for a 12V battery)
1. Choose a fast charge position (5 or 6)
2. Regularly monitor and decrease the position when the current value gets near 0 A.
3. Repeat the operation until reaching position 1 for the final charge.
Control and end of charge
- Ammeter and voltmeter show the CT 48 current and voltage output. These are therefore charger indicators. The
charge can be interrupted when power get close to 0.
- Do not leave the machine connected to the battery over 24 hours.
- Once the charge is complete, in that order : change the position of the switch to «OFF», then disconnect the char-
ger from the mains and finally disconnect the clamps from the (-) and then (+) terminals of the battery.
PROTECTIONS
MULTICHARGE CT 48 is a 48V charger which has several protections :
•
Charging clamps are insulated.
•
Protection against polarity reversal is ensured by the front fuse. It will need replacing when blown. Follow the fuse
rating printed on the machine.
•
The machine is protected by 2 fuses to avoid any risk in case of failure.
Primary fuse
Secondary fuse
•
Thermal protection: the transformer is protected by thermostat. If the charger reaches its maximum duty cycle, it
will go into thermal protection for ¼ hour then start back to charge automatically.
TROUBLESHOOTING / CAUSES / SOLUTIONS
Troubleshooting
The ON/OFF button does not switch
on when set to ON.
The machine's anmeter does not
fluctuate .
The charger is properly connected but
it does not charge the battery
MULTICHARGE CT 48
12 V - 24 V - 36 V - 48 V
Cylindrical type 6.35x31.75
Slow blow T8A
Littelfuse reference: 313008 MXP

Causes
No mains voltage
Power supply problem.
Clamps in short circuit or polarity
reversal.
The battery that you are trying to
charge is faulty.
The output voltage selection is not in
accordance with battery.
After intensive use over a prolonged
period of time, your device has
entered thermal protection mode.
Blown fuse
Bad clamp connections.
Wrong charge settings
After intensive use over a prolonged
period of time, your device has
entered thermal protection mode.
Solutions
Check that the power cord is plugged
to a 230V 50/60Hz socket. Check the
power supply network.
Check your mains power supply.
Check that the fuses have not melted
and that the circuit breaker has not
tripped
Check the voltage at the terminal
using a voltmeter. If this voltage
jumps instantaneously to 2.5V per
element, the battery may be sulfated
or damaged.
Check the output voltage switch is
settled to the right voltage of the
battery to charge.
Wait 1/4h for the device to cool
down.
Replace the fuse by a new one.
Clean the terminals and the clamps.
Check the state of the cables and
clamps.
Check that the selected voltage
matches the battery voltage.
Wait 1/4h for the device to cool
down.
