Controller

The controller can be oriented in any position as clean and dry as possible , or shield with a

cover to protect it from water and contaminants.

To

ensure full rated output power, the controller should be fastened to a clean, flat metal

surface with four screws. Applying silicon gel or other thermal conductive material to contact

surface will enhance thermal performance.

Sufficient heat sink and airflow are required for high power application.

The case outline and mounting hole dimensions are shown in Figure 1.

Check List

List

Before operating the vehicle, complete the following checkout procedure. Use LED code as

a reference. LED codes are listed in

T

able 1 .

•

Make sure the wire is connected correctly

•

Turn the PWR switch on. T he LED should blink, then keeps on when the controller

operate s normally. If this does not happen, check continuity of the PWR and return.

•

T he fault code will be detected automatically at restart .

•

With the brake switch open, select a direction and operate the throttle. The motor should

spin in the selected direction. Please verify wiring and voltage if it doesn ’ t. Also check fuse .

The motor should run faster with increasing throttle. If not, refer to Table 1 LED code, and

correct the fault according to the code.

•

Take the vehicle off the blocks and drive it in a clear area. It should have smooth

acceleration and good power.

Caution:

•Put the vehicle up on blocks to get the drive wheels off the ground before beginning these

tests .

•Do not allow anyone to stand directly in front of or behind the vehicle during the checkout .

•Make sure the PWR switch and the brake is off

•Use well-insulated tools .

4 Maintenance

Maintenance

There are no user-serviceable parts inside the controllers. Do not attempt to open the

controller. Or will void warranty. However, clea n ing the controller exterior periodically should be

necessary.

The controller is inherently a high power device. When working with any battery powered

vehicle, proper safety precautions should be taken. These include, but are not limited to, proper

training, wearing eye protection, avoiding loose clothing and jewelry , and using insulated tools.

4.1

4.1 Cleaning

Cleaning

Although the controller requires virtually no maintenance after properly installation, the following

minor maintenance is recommended in certain applications.

•Remove power by disconnecting the battery, starting with battery positive.

•Discharge the capacitors in the controller by connecting a load (such as a contactor coil,

resistor or a horn) across the controller ’ s B+ and B- terminals.

•Remove any dirt or corrosion from the bus bar area. The controller should be wiped with a

moist rag. Be sure it is dry before reconnecting the battery.

•

•Make sure the connections to the bus bars are tight. Use two wrenches for this task in

order to avoid stressing the bus bars; the wrenches should be well insulated.

4.2

4.2 Configuration

Configuration

You can configure the controller with a host computer through RS232 or USB port .

•Use straight through RS232 cable or USB converter provide by Kelly to connect the D9

connector to a host computer. Provide >18V (either J2 pin1 or J1 pin14) to PWR. Wire

power supply return to any RTN pin.

•Do not connect B+, throttle and so on. The controller may display fault code, but it doesn't

affect programming or configuration .

¤ ¤¤

O ver voltage error

1.

Battery voltage is higher than max operating

voltage of the controller. P lease check the battery

voltage and configuration.

2.

Over voltage at regeneration. Controller will cut

back or s top regeneration .

1,3

¤ ¤¤¤

Low voltage error

1.

The controller will attempt to clear the fault

code automatically after 5 second if battery

voltage returns to normal.

2.

Check the battery voltage .

3.

C harge battery if necessary.

1,4

¤ ¤¤¤¤

Over t emperature

warning

1.

The controller temperature is over 90 º C. The

controller will cut back current in the case. S top

or reduce output to ensure the temperature fall.

2.

Improve heat sink or airflow

2,1

¤¤ ¤

Motor fails to start

1.

Motor hasn ’ t reached 25 electrical RPM after 2

seconds from starting. Most likely the hall or

phase wiring problem.

2,2

¤¤ ¤¤

I nternal voltage fault

1.

Check if the B+ and PWR voltage are correct ,

refer to B- or RTN. Could be PWR voltage low .

2.

Please check load on 5V supply. Could be high

load on

5V.

Incorrect pot wiring can load it

heavily 。

3.

The controller is damaged . Please contact Kelly

for warrantee.

2,3

¤¤ ¤¤¤

1.

The throttle signal is higher than configured dead

zone at power-on

2.

The fault will disappear if restart or release

throttle.

3,1

¤¤¤ ¤

Frequent reset

1.

The controller will stop driving after detect too

many resets.

2.

Mostly because of B- or return wiring. Use

heavier and clean return wires. For dual

controllers, bond B- of both controllers together

with heavy cable or copper strip.

3.

Could be over current protection. May set max

current lower.

4. Restart will clear the error.

5. Please contact Kelly if it happens repeatedly

3,2

¤¤¤ ¤¤

Internal r eset

Reset caused by over current, h igh battery voltage or

low supply voltage . I t is normal if occurs occasionally.

¤¤¤ ¤¤¤¤

Throttle isn ’ t zero

when try to change

direction

The controller won ’ t change drive direction if throttle

isn ’ t zero. Also it won ’ t change direction at high

speed. The controller will wait throttle and speed

close to zero before change direction.

4,1

¤¤¤¤ ¤

Over voltage at

startup or

regeneration

The controller won ’ t drive motor if detect overvoltage

at power up. It will cut back regen current or stop

regen at overvoltage.

You

may set max voltage

threshold with GUI.
