1. Preface

Thanks for you choose BEDFORD B800 series high functional

frequency inverter, please read this manual carefully before use.

2. Notes for safe operation

Frequency inverter is a latest product for electric and electronic; To

guard your safety, there are signals both “danger” and “notice” in this

manual to remind you safety precaution notices during movement,

installation, operation and check.

!DANGER Misuse may cause casualty.

! NOTICE Misuse may cause damage to inverter or system.

! DANGER

•Please don’t take down, alter! Otherwise, it may cause electric

shock, fire and injure.

•Don’t open the cover during electrify

•Don’t put or insert wire, stick and filament etc. into inverter to

avoid short circuit or electric shock.

•Please don’t splash water or other liquid onto inverter.

! NOTICE

•Please don’t perform a withstand voltage testing to the components

of inverter.

•Absolutely don’t connect output terminal (U, V, W) with AC main

circuit power supply.

•Components CMOS IC on circuit board are easily affected and

damaged by static electricity, please don’t touch it casually.

•Electromotor and inverter should fit to the matched AC power;

Otherwise, it may cause operate abnormality, even burn.

3. Inspection checkpoints

3.1 Check procedure

a) Make sure inverter is same as you purchase.

b) Make sure inverter is in good condition which don’t get

damaged during transportation; if damaged, please don’t

connect with AC main power.

c) Make sure the S/N on warranty is same as inverter.

Please inform our salesperson ASAP if you find the above problems.

4.2 Operating environment

To ensure proper performance and long operation life, Follow the

recommendations below when choosing a location for installing B800

series frequency inverter, Make sure the B800 series frequency inverter

is protected from the following conditions

. Ambient temperature: hanging type, -10~45℃

Tank closed type, -10~40℃.

. Rain, Moisture (For enclosed wall-mounted type)

. Oil fog, salt spray

. Direct sunlight.(Avoid use outdoors)

.Corrosive gases or liquid

. Dust or metallic particles in the air.

. Physical shock, Vibration

. Magnetic noise (Example: welding machine,power devices etc)

.High humidity

. Radioactive materials

. Combustibles: thinners, solvents, etc.

.If few inverters are mounted into cabinet, Please kindly put them on

ventilated position where the good ventilation is available. Further to

mount the cooling fan inside the cabinet to make the ambient

environment under 45℃

. Sufficient mounting space within below stipulation

4.3 Notice

! Notice

•Please don’t hold the front cover when move, the right way is to

hold the heatsink of inverter so as to avoid falling down which

could injury person or damage inverter itself.

•Please mount inverter onto nonflammable materials like metal and

other else; please don’t mount it nearby nonflammable materials

to avoid fire.

•If few inverters are mounted into a controlling cabinet, cooling fan

must be mounted inside cabinet to ensure temperature of cabinet

inside is lower than 45℃to avoid overheat.

• Please cut offAC main power prior to remove keyboard.

5. Wire

5.1 Connection diagram

Note: 1. three phases 380V use R/L, S/N, T as AC main power input terminal, Single

phase 220V only uses R/L and S/N.

2. Braking resistors of single phase 220V/1hp-2hp & three phase 400V/1hp –

2hp are all inbuilt.

3. B800 Series inverter default as keyboard control (F-12=1), it will work after

AC main power input

5.2 Notes for operation

• Parameter F-01 can be set as Max.30000 rpm/Min. of motor rotary,

please use this parameter with care.

• If user wants to operate the RPM of motor higher (F-09/F-10

parameter) than the rated speed of motor, please confirm the

allowable range both motor and machinery.

• The cooling fan of inverter would automatically start to work once

the temperature reach 40℃, Also, it would stop working when its

temperature is under indoor.

• Please attention other relevant parameter settings once braking

resistor used.

• Please don’t check the signal on PCB when inverter is running.

• Parameters have already been set when ex-work, please don’t adjust

it casually.

6．Keyboard Operation

6.1 LCD and operation Key (B800 Series without potentiometer)

(B800-1 Series with potentiometer)

6.2 Utility for operation key

•When inverter ex-work, standard parameters are set as default.

•Press “Enter” key one second, then enter into check/modify

standard parameter group.

•Press or key to check the parameter group from F-01 to F-14

•Press “Enter” key again, which can read parameter value.

•Press or key, modify parameter value.

•Press “Enter” key again, Back to parameter group.

•If press “Enter” key more one second or standby more20 seconds,

Back to initial status prior to standard parameter group modification

•If want to enter into extended menu access(F-15-F-40)，set F-14 to

“10”，and press “Enter” key .

7. Test operation

7.1 Master some relevant functions which may help you acquire more

ideal use effects

•Maximum and minimum output frequency F-01&F-02.

The maximum and minimum speed limitations are set according to

actual individual requirements.

•Accelerate and decelerate parameter F-03&F-04.

If linear acceleration time and linear deceleration time too short on

some occasions, which may cause inverter overcurrent and let inverter

trip, which cause motor stop working.

••Stop mode F-05.

When F-05=0, inverter would diminish motor’s speed according to

linear deceleration time.

If F-02≠0, when inverter start, motor would accelerate from mini

frequency we set (F-02), when inverter stops work, the motor linear

decelerate to ‘0’and then stop work.
