LINK Systems OmniLink 5000 - Manual (Page 43)

April 12, 2012 Manual Version 1.1 5.7
Fault If the air system detects an error it will be reported on this line. A fault occurs
when a hardware or firmware problem is diagnosed by the system. See section 6
for a list of fault messages and their meanings.
Status The current status of the air system. Status messages indicate what the system is
doing in the normal course of its operation. See section 6 for a list of status
messages and their meanings.
Section 5.2.1 Air System On, Manual, and Off Settings
An air system can be set in the configuration menu to modes of “ON”, “MAN” (manual), or “OFF”.
The operator can not change this mode setting in the operation screen but the setting is reported on the
top line after the air system name for operator information. The ON setting is the normal setting for
each air system.
The mode setting affects the air system in the following ways:
“ON” Jobs that are recalled from memory will automatically take the air system to the
pressure stored in the job.
“MAN” (manual) The air pressure will not automatically change when a job is recalled. The
pressure or force setpoint can still be changed by manually entering a desired
pressure setpoint.
“OFF” The air pressure will not automatically change when a job is recalled. The
OmniLink 5000 will not control the air pressure in any way. For units equipped
with an integrated valve with manual fallback, the manual side will be engaged
and pressure can be adjusted through a manual regulator.
Section 5.2.2 Pressure and Force Setpoints
Pressure can be set in one of two ways. First, if the air system was correctly configured, the desired
force which the pressure is to create can be entered in the “Force Setpoint” row on the air pressure
screen. Second, if preferred, the desired air pressure in psi may be entered into the “pressure setpoint”
row.
For counterbalances, the “Die Weight Set” is the weight of the upper die that attaches to the slide. (The
counterbalance must also offset the weight of the press slide, but since this is a constant accounted for
when the system is configured, only the upper die weight need be entered). The upper die weight, which
is required by OSHA to be stamped on the die, can be entered in the force setpoint row.
For cushions, the “Cush Force Set” is the amount of “push” that is exerted by the air pressure times the
cylinder area.
For hydraulic overloads, the “Press Trip Set” is the value, usually in tons, at which you wish the
hydraulic overload system to trip.
Note that pressure, die weight, cushion force, and trip points are restricted items as defined in section 2.
