NORMAL
The BC 700 is provided with a PCB which allows the constant control on the output voltage of
the electromechanical battery chargers during the boost start. Through this system it is
possible to avoid damages to the electronic devices of the new generation vehicles when
the boost start reaches its voltage peak.
We recommend, that before attempting to boost start, you “fast charge” the battery for 10-15
minutes. This will improve the chance of a first time start, particularly with big engines.
When the battery is completely flat, you must “fast charge” the battery before attempting to
start, otherwise you may cause damage to the vehicles’ electronic system.
(a) Ensure that the Charging Controller is in the “O” (OFF) position.
(b) Connect the cables as for normal charging.
(c) Turn the Charging Controller switch (item 1) clockwise to the “CPS” position ( “START”
position for starting without CPS system) and hold, for a few seconds only, before
attempting to start the engine in the normal way.
The CPS PCB activates the battery charger/starter so as to give to the starter enough current
for the time necessary to start the machine motor. This CPS PCB in fact controls the boosting
current supply and when it recognizes the current need, it automatically activates the Boost
start function. For the same principle when the battery voltage reaches (at the battery end) the
safety values, the boost function automatically stops. On full batteries (charged) the battery
charger / starter does not even work at boost function.
Should starting prove to be at all difficult, it is recommended that you charge the battery at 20
Amps for 10-15 minutes before further attempts at BOOST starting.
If in doubt consult vehicle handbook or manufacturer.
IMPORTANT:
1.
If the fixed positive lead and the fixed negative lead are connected to the wrong terminals,
then a flash will occur when the 2
nd
clamp is attached.
Damage to the charging unit and the battery will be avoided as your Clarke START ‘N
CHARGE is fitted with a polarity protection feature. It will however be necessary to
replace the internal fuse. Remove the cover plate at the back of the unit (marked fuse)
and replace the burnt fuse with an exact replacement.
PROCEDURE FOR ENGINE STARTING
The boost start function with remote control is replaced on the Autostar models by the boost
start through CPS.
