◎Start conditions: Press start signal should be input. (Only when safety one process is in activation
※1
)
Press upper limit should be input. (Start lamplights up)
Press hold (hold lamp), measurement start (sensor CUT), measurement end (sensor END), external and emergency stop
should not be input.
Previous alarm should be reset. (Restart permission)
※1: At the time of die matching operation, linked with the input of press start signal, the main electromagnetic valve is
operated.
◎Operation flow (mode 1 to 7)
Press start is input → Press Main electromagnetic valve is activated (ON) → Press ram descends → Press upper limit
signal is OFF → Descending continues → Press hold is ON
※2
→ Electromagnetic valve for press lower speed is
activated (ON)
※3
→ Die contacts with product → Operated in each mode
※4
→ Return conditions in each mode are
completed → Operation of electromagnetic valve for main/lower speed ends (OFF) → Press ram ascends → Zero point
return → One cycle operation is completed
※2: If press start signal is OFF prior to the input of press hold, electromagnetic valve stops the operation, and press ram
returns to zero point.
※3: When press hold is input, even If press start signal is OFF, ram continues to descend.
(Hold): Regarding electromagnetic valve for main/lower speed, operation is kept.
※4: Mode 1: Pressurizing is carried out until reaching to the set load value
Mode 2: Pressurizing is carried out until timer operation is completed. (Timer operation starts by receiving press hold
signal)
Mode 3: After achieving setting load value, pressurizing is carried out until timer operation is completed.
Mode 4: After external signal is input, pressurizing is carried out until timer operation is completed.
Mode 5: After measurement end signal is input, pressurizing is carried out until timer operation is completed.
Mode 6: After measurement end signal and external signal are input, pressurizing is carried out until timer operation is
completed.
Mode 7: After measurement end signal is input, pressurizing is carried out until reaching to the set load value.
◎ Flow of the operation (mode 9)
Press start is input → Load measurement starts → Measurement end signal is input → Load display is fixed → Comparison
judgment → Relay output (this is continued until reset is operated)
◎Table of alarm display
If alarm sounds while press operation is ongoing (during the operation of main electromagnetic valve), press ram stops
descending (pressurizing) and returns to zero point.
Alarm 0: Load value NG
This is displayed when load value for comparison judgment does not comply with upper/lower limit value which was
previously established. Lamp for HI (high) or LO (low) lights up and relay output is carried out. Relay output continues
until reset operation is carried out.
Alarm 1: Emergency stop input
This is displayed when emergency stop is input by ram returning to the zero point (main electromagnetic valve is operating)
after press start is input. Lamps for HI (high) and LO (low) simultaneously light up and relay output is carried out. Relay
output continues until reset operation is carried out.
Alarm 2: Cycle time error operation (cycle-over)
This is an internal timer. (Initial value: 10 seconds.) This operates after press start is input. This is displayed when the
internal timer operation completes before operation in each mode is completed. Lamps for HI (high) and LO (low)
