DESCRIPTION
The Fast Charger is a battery charging system that allows for opportunity
charging of an electric vehicle. The LSV-100 is a stand-alone unit that is
externally isolated from the vehicle and secured to its own Pedestal style
mount (sold separately) or mounted to a wall.




                       LSV-100

                                                                               Pedestal Mount


The Convenience Charger is a unique battery
charging system that allows for opportunity
charging of an electric vehicle. The LSV-2472 is
ideally suitable for electric vehicles operating
in applications such as campuses, commercial
fleets, military bases and resorts. This unit is
special as it is portable and easily transferable
from one location to another.


                                                                                                   LSV-2472
              Please refer to your Owner’s Manual for more detailed information regarding your vehicle.
OPERATION
Settings
The charger is fully configured prior to leaving
the factory. Each charger is programmed and
will automatically recognize distinct valve-
regulated-lead-acid battery system voltage
configurations; 72-volt.

Start-up Sequence
After the proper connection has been made
to the AC line, the AC input breaker may
be closed, and provided the Fast Charger                                                         LSV-100
Receptacle kit has been properly installed,
the LSV-100 is ready to charge.
When a vehicle battery system charge is
required, park the vehicle with the vehicle
charge port near the charging unit and
securely connect the DC output cable to the
Fast Charge Receptacle on the GEM vehicle.
Charging will automatically commence. The
vehicle’s digital display will power on as                                          Fast Charge Receptacle
well to indicate charge status. Find more
information on ‘Charge Connected’ and ‘State
of Charge/Battery Discharge Indicator’ in your
Model Year specific Owner’s Manual. Follow
all proper guidelines and posted ‘WARNING!’
and ‘CAUTION!’ labels.

                                                                                            Digital Display




              Please refer to your Owner’s Manual for more detailed information regarding your vehicle.
General Operation
The charger is equipped with automatic
charge initiation. Upon securely connecting
the charge connector, the charger will
automatically identify the specific battery
voltage and charging will commence,
provided that no fault condition has been
identified.
The charger user interface consists of four
LEDs on the front panel of the unit (from top                                     Charger User Interface
to bottom, except LSV-2472 models):
White: The charger has been powered up and is ready for use. The vehicle
can then be connected to the charger. (This LED normally blinks).
Blue: Charging is underway. The speed at which the blue light flashes
indicates the rate of charge being supplied to the batteries. A fast flash
speed means more current and a slow flash speed means less current.
Green: 80% State of Charge. Charging has completed and it is safe to
disconnect the vehicle from the charger. Charging continues if left
connected.
Red: A fault condition has been identified. For assistance call GEM Technical
Support at 866.764.0616.
Charge Interruption
If it is necessary to terminate a charge cycle while the charger is operating,
slowly remove the charge connector from the vehicle. The charger will
stop delivering current once the pilot circuit pins disconnect. The pilot
circuit pins are the first to disconnect compared to the other pins. As the
DC output cable is disconnected (and the pilot pins disconnect), the main
drive control system of the charger stops delivering power. This allows the
DC output cable to be safely disconnected from the vehicle.



              Please refer to your Owner’s Manual for more detailed information regarding your vehicle.
Troubleshooting
The LSV-100 Fast Charger is equipped with a red LED on the front panel
of the unit. This LED will illuminate in the event of an error. The LED will
repeatedly flash a given number of times between 1 and 8 with a 2-second
pause between a series of flashes. The number of flashes per series
corresponds to one of the following fault conditions:
1 Flash - Vehicle Detection Fault - Battery pack voltage out of range, too high/
low.
2 Flash - Current Not Detected - Related battery pack voltage detection issue;
no connection, control not responding; Current less than 2 amps.
3 Flash - Unexpected High Current - Related battery pack voltage detection
issue; Current in Step 3 jumped greater than 40 amps.
4 Flash - Over Current/Under Voltage - Current exceeded 108 amps for 0.3
seconds.
5 Flash - Under Current/Over Voltage - Current less than 2 amps or voltage greater
than 118VDC; loss of current caused spike in voltage for more than 2 seconds;
exceeded 115VDC in Step 3, possible Open circuit battery pack or dead pack.
6 Flash - Thermal Fault - Charger’s Temperature sensor on vehicle or internal
Module or Rectifier temperature exceeded 122 degrees Fahrenheit.
7 Flash - Invalid Start Current/Programming Fault - The control failed to
communicate with the module; Module disconnected or Controller defective.
8 Flash - Amp Hour Limit Reached - Maximum Amp/hour rate exceeded.

To clear any fault condition, disconnect the vehicle from the charger, wait
about one minute, and then reconnect the vehicle to the charger. In the
event that you encounter difficulties during the troubleshooting, or during
normal operation of the charging station, please contact a GEM Technical
Support representative at 866.764.0616 or e-mail service@gemcar.com.



               Please refer to your Owner’s Manual for more detailed information regarding your vehicle.
Maintain H2O Levels (Flooded Only)
The water level in all 6 of the flooded batteries should be checked monthly
for proper water level, or more frequently with heavy usage. The level
should be in between the battery plates and the bottom of the fill well. The
battery plates should be visible when looking into the fill well. If not, use a
flashlight. Add (distilled) water only after charging unless the water level is
below the top of the battery plates. In this case, add just enough distilled
water to cover the plates, charge then recheck the level. CAUTION! Never
charge batteries if plates are exposed above water level.

Charge Completion
The charger can be left unattended and will stop delivering current when
the battery is full. The green Charge Complete LED will illuminate on the
Fast Charge unit and the vehicles digital display will illuminate the green
Charge Connected Indicator. The DC output cable can be disconnected
from the vehicle. The vehicle is now ready for use. Enjoy!
