Fault Time
If the pressure in the counterbalance goes out of tolerance due to a leak or
any other reason, a countdown starts. The module will try to bring the
pressure back into tolerance before the countdown expires. If it cannot
correct the pressure, the press will be stopped. The fault time is the
countdown in seconds. Suggested value is 20 seconds.
Transducer Full Scale This value depends on the full scale rating of the pressure transducer
being used. All pressure transducers must have a 4 to 20 milliamp output.
The “Transducer Full Scale” is the pressure that the transducer is reading
when its output is 20 milliamps. It is suggested that the full scale rating of
the transducer be at least two times the maximum air pressure rating of the
counterbalance. Since counterbalance air pressure is not constant and
increases as the slide approaches bottom dead center, a transducer rating
of at least two times maximum air pressure is suggested.

Figure 4-5 Cushion Configuration
There are several parameters that must be configured in this screen. The editing cursor indicates
which parameter is currently selected. Softkey 1 (the uppermost vertical softkey) will change its
description based on the parameter and, when pressed, allows the currently selected parameter to
