Electric lock
Description of pin definition:
Pins 1, 2, 3, 4, 5, 6;
The pins 3, 5 are normally not used;
Pins 1 and 6 - power supply, pin 4 - ignition (con-
trol power relay coil), pin 2 - starter;
Specification of the positions of the electric
lock
"OFF"-the position to insert and extract the
electrical lock key. At this gear, cut off the power
the electrical equipment on the vehicle. Except
for some electrical equipment (such as dome
light), which are controlled by the battery
disconnect switch instead of the electric lock.
"IGN"-the first gear of the clockwise rotating key
after inserting the key to electric lock. "IGN"
connects the powers of electrical equipment
throughout the machine, which are powered by
battery.
"START"-the second gear of the clockwise
rotating key after inserting the key to electric
lock. Such gear starts the diesel engine, which is
incapable of self-hold. The key to electric lock
returns automatically to "IGN" once it is
loosened.
Precautions
After starting the oil engine, loosen the key of the
electrical lock immediately to make it return to its
position. Otherwise it will lead to serious
electrical fault.
Switch off the electric lock if it fails to start for the
first time, then proceed on to second starts. First
turn the electrical lock key to "OFF" position.
Second turn it to the "IGN" position; Finally to
"START" position, which completes a startup
circle.
If the diesel engine fails to start within 15S,
switch off the electric lock. Continual starting
should be less than three times. Each start time
shall be controlled within 15S, or else power loss
may be resulted in for the continuous high-power
output of battery.
