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 nal 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 nally 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.
12 V - 24 V - 36 V - 48 V
Primary fuse Cylindrical type 6.35x31.75
Slow blow T8A
Littelfuse reference: 313008 MXP
Secondary fuse BF1 type 40A
Littelfuse reference: 142.5631.5402
• 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 Causes Solutions
The ON/OFF button does not switch
on when set to ON.
No mains voltage Check that the power cord is plugged
to a 230V 50/60Hz socket. Check the
power supply network.
The machine's anmeter does not
uctuate .
Power supply problem. Check your mains power supply.
Clamps in short circuit or polarity
reversal.
Check that the fuses have not melted
and that the circuit breaker has not
tripped
The battery that you are trying to
charge is faulty.
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.
The output voltage selection is not in
accordance with battery.
Check the output voltage switch is
settled to the right voltage of the
battery to charge.
After intensive use over a prolonged
period of time, your device has
entered thermal protection mode.
Wait 1/4h for the device to cool
down.
The charger is properly connected but
it does not charge the battery
Blown fuse Replace the fuse by a new one.
Bad clamp connections. Clean the terminals and the clamps.
Check the state of the cables and
clamps.
Wrong charge settings Check that the selected voltage
matches the battery voltage.
After intensive use over a prolonged
period of time, your device has
entered thermal protection mode.
Wait 1/4h for the device to cool
down.
