The machine adopts AC 220V/60Hz/3 phases power supply. Power transformer will transfer it to 220V voltage for motor and DC 24V for TPC.
The machine has dedicated electrical control cabinet and work station. The work station can be put arbitrary, the operation panel set optional switch, control button and light, that can control the machine. The inner electrical cabinet has switch, thermal relay, ac contactor, time relay, transformer and intermediate relay control circuit. The machine has adjustment and semi-automatic working types, and you can select according to your products requirements. The adjustment mainly used to adjust the machine and molds.
On the situation of semi-automatic, just put the hands run button, then can finished the produce in one time.
Hands run button must put at the same time, and the time can’t be more than 0.5 second, then the machine can working in right way.
Please check electrical Schematic diagram.

3）Other actions
Emergency stop: In case of emergency status, Operator can click Emergency stop button to stop machine immediately.
4) Electric interlocking and electrical protection device
Main power circuit adopts automatic switch short circuit protection, motor with thermal relay overload protection, control circuit adopts high marks broken small circuit breaker short circuit protection.
Every electrical device has reliable grounding device for special purpose, to ensure safety.
Security and Protection Device
1. Button of Emergency Stop
In case of emergency status, click the Emergency stop button, machine will stop working immediately.
2. Button of Hands Operation
To operate the machine with left and right hands at the same time, the hands limit of synchronization time is 0.5 to 1S
3. Security Sensor Device
There is a security sensor device in front of operation table to protect operator. In the period of machine working, insert your body into security sensor, the machine will be stop and return RAM automatic.
4. Overload protection
Pressure of pressure sensor can be displayed on the TPC. In case of pressure overload 24.7 Mpa, machine stop working automatic, and light alarm with three-color light. To ensure the machine work normal, restart the power of machine.
5. Protection net
To ensure the security of operator, there are a maintenance platform with protection net mounded at the sides of machine.
c-frame hydraulic press Machine Lifting and Installation

Diagram-6 Power cable connection
Notes:
Please change the connection order of L1 L2 and L3 in case of motor running direction is Counterclockwise.
Notice of Machine Test
- Ensure the oil box is clean and all the screw of and screw boltare tight.
- Please clean the oil box before inject hydraulic oil if there is some impurity and water in it. Otherwise, inject hydraulic oil is forbidden.
- Open the oil cover in the back of host machine and inject anti-wear hydraulic oil#46 (about 200kg).Stop injecting when the oil reach the red graduation.
- Check the run direction of fan, ensure it’s run in clockwisedirection and without block. Check the run direction of motor to ensure it running in clockwise direction too. Please start to operation machine one mintues later,after motor run correct.
- Don’t keep the hydraulic system under full pressure status for a long time, to avoid hydraulic components damaged when hydraulic oil in high temperature for a long time.

Maintenance of c-frame hydraulic press Machine
- Clean the oil box and change the oil per 6 month Don’t change the oil less than 6 months at the first time and second hands oil can be used again after filtration.
- The used rule of hydraulic oil(#46): hydraulic oil must be filtered before used, the capacityof hydraulic oil must reach the indicate place and it’s temperature must keep in [5º, 45º].
- Pressure gage must be authenticate per 6 months.
- Machine long-term disabled, each should be exposed machined surfaces cleaned and oiled.
- The max. pressure is 100T (23MPa) +1T, too large pressure to make the column eccentric strain or other undesirable phenomena occur.
Instruction of Operating Safety
- The operator must understand the structure and features of machine very well, otherwise not be allowed to start the machine.
- Stop machine immediately when c-frame hydraulic press machine has a serious oil spill or work abnormal (action is not reliable, noise, vibration, etc.). and analyze the causes and troubleshoot, Don’t running the machine enforced in justification sickstatus.
- Don’t use the machine in overload pressure status.
- Don’t overload the max. stroke and dies close height must more than 200mm.
- Don’t adjust and repair the mold in work area when the c-frame hydraulic press machine is running. Before installation of mold, open the cylinder to the maximum to the top, locking safety hydraulic cylinder to prevent the slider fall out by themselves to cause personal injury.
Set Technical Parameter (Important)
1.After finish cable connection, please check them again and ensure everything is correct. When oil box is on the top of the host machine, please upper the oil pumping and oil drum at a suitableposition to inject the hydraulic oil. Check the oil capacity in oil tank level display meter, view the oil temperature at the same time.
2.Power on the breaker in electrical box, close the door of electrical box and rotate switch(the left one below) on to power on position.
3.Click button operation panel to run oil pump and start and stop pump immediately. Check running direction of motor, it must be a clockwise direction. Otherwise, please correct it with change the electric phase.
