Preparation for Operation on Toshiba Injection Molding Machines 2.1 Precautions for Initial Power ON Check the following before turning the power on for the first time. 1) Check if circuit breakers matched to the inverter are installed. 2) Check if the power and earth lines are securely connected. If three phases (R, S, T) of power input are reversed, the mold thickness setter and injection unit will move to the wrong direction possibly causing an unexpected accident or breakage of the mechanism. 3) Check the cooling water line for a secure connection or no leakage. 4) Check if covers are securely attached. 5) Check if peripheral equipment is securely connected. 6) Check if the installation space around the machine is ample. 7) Check if the machine area is clean and free of unnecessary items, and tools and materials are set in places. 2.2 Inspection Prior to Starting Operation [1] Cooling water check Check that cooling water is flowing under the hopper by observing the flow checker located on the non-operation side of the machine. 2.3 Starting the Machine [1] Power

How to Hang / Load TOSHIBA All-electric Injection Molding Machine Work Procedure 1. Mechanical unit (1) Check the foundation surface for unevenness. (2) Remove the top cover from the safety gate. This cover is removed at a time of shipment from the factory. (It is not attached to EC230SXⅡ) (3) Set eyebolts or lifting jig on the prescribed positions of the machine. Apply wires installation jig onto the eyebolts or lifting jig. (4) EC30SXⅡ～EC180SXⅡ：Apply wires onto wires installation jig to unload the truck. EC230SXⅡ：Apply wires onto wires installation jig and projection to unload the truck. Refer to section 3-2 about machine weight. Refer to section 3-3 when moving the machine by a forklift. (5) Do not make a step on the oiling piping unit, when slinging work wire ropes. (6) Use universal rollers to locate the machine at the prescribed position. (7) Use a crane or jack to lift the machine and install leveling pads. (8) Fit the supplied top cover on safety gate. (It is not attached to EC230SXⅡ) (9) Place a level measuring instrument on the leveling surface

Safety Precautions for the Use of Hoses of Toshiba Injection Molding Machines * For auxiliary equipment (e.g. Hydraulic core puller, Hydraulic valve gate) (1) Do not touch or look into any hose or metal fitting during pressurization. If a hose or metal fitting is broken, it may cause injuries such as burns, and in addition it may cause the fluid to soak into the skin and damage biomedical tissue. If it is imperative for operators to touch products while working, mount a protective cover made of a strong enough resin on that section in order to provide a clearance. (2) Do not damage hoses. If the external layer of a hose is damaged and its reinforced layer is exposed (external damage), the reinforced layer is damaged (e.g., corrosion) by moisture soaking in through the damaged area, and the hose will burst at an early stage of its life. If external damage is detected on a hose, replace it with a new one. (3) Do not twist or pull hoses. If a hose is pressurized while it is twisted or pulled,

Precautions for the Electric System of Toshiba Injection Molding Machines (1) Electric construction for auxiliary equipment Do not feed power source to any auxiliary equipment from the secondary circuit of main breaker in the electric cabinet of the injection molding machine. Feeding source from electric circuit of the machine will be the cause of a fire and machine malfunctions. (2) Grounding the machine and control cabinet Ensure that the machine frame and control cabinet is grounded and that connections are not corroded. Regularly exercise extreme care to avoid short-circuiting. (3) Maintenance, inspection, and connector removing Be sure to turn off the power before maintenance or inspection of electric circuit or removing the connectors. Failure to comply can cause a serious accident resulting in injury or death. (4) Inspection for heater wiring Ensure that the heater wiring is not loose and that bare wires are not exposed. Be sure to turn off the power and measure voltage at inspection points to ensure that the power is off before inspection. Insulate the heater wire connections with heat-resistant tape. Polyvinyl tape should not

Precautions for Clamping of Toshiba Injection Molding Machines (1) Safety gate damage Damages to the transparent panel of the safety gate require immediate repair. Never remove molded products from a hole. Be sure to open the safety gate before taking out molded products. (2) During machine operation, never put your hands into the injection molding machine or around a safety gate. Never touch moving parts of the injection molding machine. (3) Do not operate the machine with safety gates, safety guards, or safety devices left removed. (4) Securely turn off the power and check that the ejector is located at the retract limit and core at the out limit before starting work on the mold. (5) Inspection for safety devices Check that safety devices function securely at starting of work or changing of workers. (6) Inspection for mold mounting bolts Check the mold mounting bolts. If the mold is not properly secured, the mold may slide or fall during the injection molding process. Extreme caution should be exercised especially during NOZZLE CONTINUOUS ADVANCE. Secure proper bolt size, number and threaded

Mechanical Safety Device of Toshiba Injection Molding Machines The safety device is designed to secure the safety mechanically by interrupting mold closing with the opening of the safety gate. If the mechanical safety device functions as a result of mold closing with the opening of the safety gate, immediately contact your nearest service station to call service personnel for inspection on electrical devices. Opening the safety gate on the operation side rolls the guide roller and the hook that synchronizes with guide roller turns toward the link housing and fits into the groove provided on the shaft to prevent mold platen closing. Closing the safety gate on the operation side makes the guide roller return the position and the hook that synchronizes with guide roller turns away from the link housing out of the groove provided on the shaft to enable mold platen closing. NOTE: This safety mechanism does not function during mold platen opening.

Electrical Safety Device of Toshiba Injection Molding Machines The safety device is designed to secure safety by shutting off the electrical circuit with the opening of the safety gate. (1) Safety gate on the operation side The safety gate on the operation side is equipped with gate close limit switches （LS1A， LS1A1）. Opening the safety gate stops every machine movement in all operation modes by limit switches. NOTE: When the safety gate is opened in [AUTO] or [SEMI-AUTO] of OPERATION mode, close the safety gate and press [START] button to restart operation. NOTE: Electromagnetic locking device (LS1A3) might be added depending on the safety standards of the country where the machines are installed. 【Machines for China】 The safety gate is locked by electromagnetic locking device all the time.
