3. Load measurement complete signal (Examples for caulking)
Shown on the left is an example for checking
a caulking load using the timer "b" contacts
from the press timer for press fitting
operations. Please make sure to design the
circuit so that the timer contact is reset at the
upper end of the press' stroke. Make sure to
install noise suppressers across the coil of the
solenoid valve that drives the press, and the
timer contacts used for driving the press. No
noise suppresser is required between
terminals
③
and
④
.
This is useful for checking a caulking load
and to construct a destructive test system
using a press stop. Enter a signal while the
press is rising.
＊
Make sure you only use this arrangement
in the peak load mode.
4. Use the comparison results for outputting signals
This circuit sounds a buzzer to let the
operator know that an NG occurred. Make
sure to use a buzzer that can handle 20 mA
of current, or less.
Example: Model"EB2136" made by
Matsushita Electric Works, Ltd.
This circuit can be used to stop the
movement of the hydraulic press instantly
when an NG occurs, or in an emergency.
