[1] For safe use

■For safe use

Always observe the following matters to safely use the Mitsubishi industrial electronic sewing machine PLK-G

Series.

Before starting

Before using this control unit, read all of the technical manuals carefully, and correctly use the unit

following the manual. Also read the "Mitsubishi Industrial Sewing Machine Technical Manual <Sewing

Machine Head>" for details on the general configuration and sewing machine head.

Application and purpose

This control unit is designed to drive and control the Mitsubishi industrial electronic sewing machine

PLK-G Series. Do not use this control unit for other applications or purposes. Do not use this control unit

until it has been confirmed that safety measures have been accurately taken for the installed electronic

sewing machine head section.

Working environment

Do not use this control unit in the following type of environment.

(1) Power voltage

* Where the voltage fluctuation exceeds ±10% of the rated voltage.

* Where the specified power capacity (refer to page [4]-2 “5. Power capacity”) cannot be ensured.

(2) Magnetic noise

* Where strong fields or magnetic fields are generated, such as near a high-output high frequency

oscillating machine or high frequency welder.

(3) Temperature and humidity

* Where the ambient temperature is 35°C or more and 5°C or less.

* Where the unit will be subject to direct sunlight, or outdoors.

* Near sources of heat, such as heating appliances.

* Where the relative humidity is 45% or less, or 85% or more, and where dew may condense.

(4) Atmosphere

* In an atmosphere containing dust or corrosive gases, etc.

* In a flammable gas or explosive environment.

(5) Vibration

* If excessive vibration could occur when installed on the sewing machine, separately install the

control box.

■Installation

Control box

Correctly install the control box according to this manual.

Accessories

Always disconnect the control unit from the main power supply before installing the accessories listed in

this manual. (Turn the power switch OFF, and disconnect the plug from the socket (power supply line).)

Cable

(1) Lay the connection cables so that excessive force will not be applied during operation. Do not

excessively bend the cables.

(2) Cables laid near operating machine sections must be separated by at least 25mm.

(3) Before connecting the power cable to the control box, confirm that the power voltage matches the

specifications given on the control box's rating nameplate and factory shipment voltage nameplate.

Connect the cable to the indicated positions, and then supply the power. When using a power unit,

connect the cable to the power unit and supply the power. In addition, when using a power unit,

confirm that the power voltage matches the specifications given on the power unit's rating nameplate.

Turn the power switch OFF before making any connections.

Grounding

Always ground the power cord's grounding wire.

[1] - 2

Enclosed units and accessories

Connect the electrical enclosed units and accessories only to the positions indicated in the manual.

Removal

(1) Always turn the power switch OFF and disconnect the plug from the socket (power supply line) before

removing the control box.

(2) Do not pull out the cord when disconnecting the plug. Always hold the plug receptacle when

disconnecting the plug.

(3) Note that a high voltage is applied inside the control panel, so always turn the power OFF and wait

at least ten minutes before opening the control box cover.

■Maintenance, inspection and repairs

(1) Follow this manual when carrying out maintenance or inspections related to this control unit.

(2) This unit must be repaired, serviced and inspected only by a worker that has received special training.

(3) Always turn the power OFF before replacing the needle or bobbin, etc., on the head.

(4) Use genuine replacement parts for repairs and maintenance.

■Other safety measures

(1) Keep fingers away from all moving machine parts (especially around the sewing machine needle,

etc.).

(2) Never drop the control unit, or place objects in the clearances.

(3) Do not operate the sewing machine without the protective parts such as the cover, or protection

devices such as the safety breaker.

(4) If any damage is observed in the control unit, if the unit does not operate correctly, or if the operation

is suspicious, always suspend operation. Only operate the machine after the supervisor has adjusted,

repaired or inspected the machine.

(5) The user must not make improvements or changes without instruction from Mitsubishi.

[2] Precautions for use

Warning

1. Do not place foot on the foot switch when turning the power ON.

2. Always turn the power OFF when leaving the sewing machine.

3. Do not inspect the control circuit with a tester.

The tester voltage could be applied on the semiconductor

parts, and cause damage.

4. Always turn the power switch OFF before tilting the sewing

machine head, replacing the needle, or passing thread through the

needle.

5. Always ground the grounding wire.

Always ground the provided grounding wire

(green(green/yellow)).

6. Do not use excessive wiring.

7. A high voltage is applied inside creating a hazardous state, so

always turn the power OFF and wait ten minutes before opening

the cover.

High voltage risk

8. Radiation fins and other parts may be hot. Do not touch the parts.

9. The sewing machine will coast to a stop when the power is turned OFF or a power failure occurs during sewing machine operation.

10. Always align the connector shape and direction, and securely insert the connector.

11. If the position detector's connector dislocates, or the sewing machine is completely locked, the motor will be turned OFF automatically for a

set time to prevent burning. (Note that the motor may not turn OFF if there is incomplete locking or an overload.) When the fault has been

recovered, turn the power OFF and ON once to resume normal operation. The same type of operation will take place if a detector fault or

disconnection occurs.

12．Use the machine away from strong noise sources such as high

frequency welders.

13. When connecting the external switch to an optional connector,

etc., keep the signal wire as short as possible. A long wire could

cause malfunctions.

Use a shielded wire for the signal wire when possible.

14. If the fuse blows, remove the cause, and replace the blown fuse with one having the same capacity.

15．Attention when power supply is turned on again

Please make sure that turning on the power supply switch,

after the LED of the front panel on the controlbox is completely turned off.

(Please do not turn on the power supply again while displaying

the screen of the oepration panel.)
