Selection of operation mode #

There is an operation mode selection switch “SA2” on the operation panel. By changing the position of the switch, the following operations can be carried out on the machine:

Adjustment (turn the “SA2” switch to the “SA2-3” position)

Press the “SB6” and “SB7” buttons on the operation station with both hands at the same time, the ram can make a rapid downward movement, and the ram stops at the speed change point.

At this time, the foot switch “S1” can be used to continue the operation, and the ram moves down to the bottom dead center at the working speed.

Note:

• Before the ram reaches the speed change point, if one of the two-handed operation buttons (SB6, SB7) is released, the ram will return immediately. To restart, you must release the other button, and then press the two buttons at the same time.
• Once the ram has passed the speed change point, release the foot switch “S1” and the ram will stop immediately. Re operating the foot switch “S1” will make the ram continue to go down.

Cycle hand and foot operation (turn the “SA2” switch to the “SA2-4” position)

Press the “SB6” and “SB7” buttons on the operation station with both hands at the same time, the ram will move downward quickly, and the slider will stop at the speed change point.

Change the foot switch “S1” operation, the ram moves down to the lower dead center at the working speed, and automatically returns to the upper dead center after the lower dead center stops for a certain time, and the slider movement stops.

Note:

• When the ram does not reach the shift point, if one of the two-hand operation buttons (SB6, SB7) is released, the ram will immediately return to the top dead center. In order to restart, the other button must be released, and then press the two buttons at the same time
• Once the slider has changed speed, release the foot switch “S1” and the ram will stop immediately. Re operating the foot switch “S1” will continue to move the ram downward.
• Press any one of the emergency stop buttons “SB1-SB3” to stop the return movement.

Cycle manual operation (turn the “SA2” switch to the “SA2-1” position)

Press the “SB6” and “SB7” buttons on the operation station with both hands at the same time, and the ram will make a rapid downward movement. When the ram moves to the speed change point, it will automatically turn to the lower dead center, and automatically return to the upper dead center after the lower dead center stays for a certain time, and the ram movement stops.

Cycle foot operation (turn the “SA2” switch to the “SA2-22” position)

Pedal down switch “S1”, and its ram movement is the same as above.
