Precautions before Operating Toshiba Inejction Molding Machines
(1) Read this manual before operating.
(2) Keep this manual for future reference.
(3) Secure installation space around the machine according to the foundation drawing.
(4) Connecting the power source.
Strictly observe the following ordinances of the Ministry of Economy, Trade and Industry when installing the injection molding machine inside Japan.
a) Grounding work
The customer’s personnel who are qualified to perform such work shall perform grounding work. See the table below for installation resistance for the grounding. And also, please connect a metallic body of peripherals with the machine main earth bar (pole) at the same time.
| Supply Voltage(V) | Resistance |
|---|---|
| V≦300V | 100Ω |
| Ｖ＞300V | 10Ω |
b) Installation of circuit breaker
Install a circuit breaker in the electric line of this injection molding machine. Locate this circuit breaker on the power side of or inside the power switchboard. It is recommended that a medium-sensitivity, high-speed type (100 mA) circuit breaker to meet inverter be equipped.
| Manufacturer | Model |
|---|---|
| Fuji Elc. | EG-B series SG-B series |
| Mitsubishi Elc. | NV-C series NV-S series |
(5)Power source voltage
Power source voltage fluctuation must be maintained within 10 % range of rated value.
(6)Cooling water
For the quantity of required cooling water, refer to the instruction manual “APPENDIX”.
However, it may vary depending on ambient temperature, water temperature, molding conditions or other factors. Additionally, it is predicted that deposits will adhere to the interior of the piping over long period of use. It is therefore recommended that piping and equipments allowing three times the required water flow be provided.
(7) Plant air source
Provide air source of 0.5 MPa or higher pressure when installing optional equipment of air blow, pneumatic core puller, powered safety gate for opening.
(8) Conditions for operation and storage
The following conditions must be strictly maintained to avoid operation failure.
a) Ambient temperature (during operation) +15 °C ~ +45 °C (59°F ~ +113 °F)
b) Ambient temperature (during storage) -40 °C ~ +70 °C (-40°F ~ +158 °F)
c) Ambient humidity 30 %RH ~ 85 %RH (No dew allowed.)
(9) Be sure before operating to check that the machine is securely attached with safety plates and that safety devices function normally.
(10) Do not operate the machine unless thoroughly instructed on safety rules and operations.
