Fault Time If the pressure in a counterbalance, cushion, or hydraulic overload system goes

out of tolerance due to a leak or any other reason, a countdown starts. The control

will try to bring the pressure back into tolerance before the countdown expires. If

it can not correct the pressure, the press will be stopped. The fault time is the

countdown in seconds. Suggested value is 20 seconds.

Tolerance This is the amount by which the system will allow the pressure to vary and still be

considered “good”. For instance if tolerance is 2, then a setting of 30 psi will be

considered “At Pressure” from 28 to 32 psi. Suggested setting is 2.

Transducer Type This value depends on the kind of pressure transducer used on the system. Table

4.1 gives the transducer type number to use with various transducers. Contact

Link for others. Note that the used pressure range is typically half the actual

pressure range of the transducer. This allows the transducers to better survive

pressure shocks that may occur in operation.

Valve Type This parameter only appears when a hydraulic overload is being configured.

For hydraulic overloads controlled with “0-10Volt Out” proportional voltage,

refer to table 4.2 for the proper control type based on the servo-valve used to

control the system.
