3 Leveling and Electric device

3.1 Leveling

Leveling is the No.1 factor determining the accuracy of machine.

To level the machine is the most basic operation to have influence on the owrkpiece and the

life span of machine.

First, place machine on the levelling sheet, and then align the levelling bolt on machine and

lower it in position.

The level gauge suited for this use is that has the sensitivity scale of 0.02 mm per in.(The

length of level gauge is 200 mm). Do not use the level gauge used in construction field.

Handle level gauge so that each end maintains same direction.

The surface where level gauge is placed should be clean and free from any dust.

Adjust the on the center of table as follows so that the horizontal reading does not differ from

the longitudinal reading by more than 0.04 mm/m.

When fis the levelling bolt, be careful not to be loosen it.

Foundation bolts may be used for fixing if mechanical vibration rises now and then due to

ununiform work or intermittent cutting.

Check the level every day for 2~3 days from the installation. Then check it every month for six

months from installation, and every three months thereafter.

3.2.2 Check for power supply

The equipment is delivered under our strict Q.C, but in case of state before delivery is not

maintain to 100% by vibration during transportation for long time and temperature change,

occurs. Equipment installer verify following check before power supply and then supply the

power.

1. Checks before power supply

(1) Verification for assembled state of each of parts in control panel (part loosing).

(2) Verification for assembled state of assembled connector in control panel and unite.

(3) Check and supplement whether assembled wire is loosen of Terminal Block

(4) Check setting current value of Breaker for protecting Motor (Check that it is met to

Marking section)

(5) Check that connector assembled to control panel, is screwed.

(6) Check other general motor connection wire and signal and power connector of Servo /

Spindle Motor is assembled.

(7) Check joint section of hose connection (hydraulic/cutting oil/pneumatic) for machine

section.

(8) Check (RED Colored Bracket) separation of each of fixture (X, Y, Z axis, for lathe, X, Z

axis)

3.2.3 Check before operation

1. Before operation, read install and operation manual supplied from our company and

operate according with indicated method.

2. To operate safely, machine purchaser direct that only employees trained in basic handling

course, are operated machine.

3. After supplying main power, check that main parts of machine are leaked, while the

machine keeps normally operated (Machine Ready) status and use after lubrication Unit

is normally lubricated.

2. Changing Electric Units According to Voltage and Frequency

According to the voltage and frequency of the power of factory, it needs to change the

setting of electric applications. Prior to changing, check its voltage and frequency.

Power Voltage: 200/220 V±10 %

Power Frequency: 50/60 Hz±1 Hz

• If the voltage fluctuated seriously, it may cause disoperation of the

machine and failure of the electric and electronic parts. Therefore, set

the fluctuating rate not to exceed ±10 %.

(1) Tab Changing for Controlling Transformer

Open the door of the Electric Control Panel, remove the plastic cover of Transformer

and then change the wiring as shown in the following table.

Table 2-9. Voltage

Voltage R2 T2

191~210 V 200 V 0 V

211~240 V 220 V 0 V

Fig. 2-14 External Transformer

Electric equipment generating high frequency noise(Welding machine,

high frequency dryer, anti-electric processor) shall use a separated

distributing board or install another distributing board to be apart more

than 20 m.

When the voltage exceeds the allowance or fluctuate too much, a

constant voltage equipment is required. If equipment like welding

machine is to be contacted to the power line, excessive noise may be

generated and cause machine malfunction. Separated those equipment

from machine power line.

3. Connection of power line

Before installation and work, read following precaution and perform the work.

Connect power line after equipment is completely installed. After verify that main power switch

of equipment (QF1: adjacent in door section or side section of control panel or transformer),

connect the machine to main power switch firstly.

At this time, terminal for grounding exists around main power switch. After connecting firstly

using specified ground wire to prevent equipment and person from electrical shock and

contact according with L01, L02, L03 sequence.

For opposite power line, after check that 3 phases voltage and setting voltage is matched in

user’s facility power inlet (distribution power panel), if it is not fault, connect PE, L01, L02, L03

sequences with breaker for distribution power panel is switched Off.

In additional, Check that each of phase is correctly connected with Phase Detector to match

phase sequence of 3 phases.

• Power inlet sequence for machine

Enter according with facility distribution power panel breaker ON → Main switch ON →

Operation panel power switch ON sequences.

If 3 phases, 4 lines power connection, power connection is different according with supply

voltage of equipment, In this case, contact to our electrical technician and then install it.

• Supply the power and then operate the machine after following is checked.

After power supply, with operation panel power switch ON, if indication of machine lubricating

Gauge is not reached to normal pressure (motor is rotating), phase of supply power is

changed and check that phase of applicable power and main power line is changed after

power shut off.

• This machine is applied TN power line system,

• TT Power line system must be applied ELB

• If you want ELB(Earth Leackage Braker) you can purchase

• Please check the earh line(PE) every 6 month

• If you move the machine, You must check the earth line(PE)
