6.3
Ctr-Bal Vented -Stop A pressure setpoint of 0 was entered for a counterbalance. The dump valve is
left open in this condition. Unlike a cushion, this is considered a stop
condition.
Hyd Overload Tripped The hydraulic overload operation screen will display this message when the
press hydraulic overload system is tripped.
Waiting for Top The hydraulic overload system is waiting for the press to reach the top of the
stroke before it adjusts the hydraulic overload setting.
LMC is Out The Link Master Control relay is disengaged for some reason (possibly an
error at the control). No air adjustment may be made while the LMC is
tripped.
Section 6.4 Slide Adjust “Fault” Messages
None No errors present.
Up and Down Reversed The “Up” relay has been connected to the “Down” side of the motor starter
and vice versa. The system checks position when moving the slide and
generates this message if it goes in the opposite direction from that intended.
Slide Did Not Move If the slide does not move within approximately 2 sec this error will be
generated. Possible causes are counterbalance pressure so far off that the slide
adjust motor cannot overcome it, wiring problems, starter overloads, a
picofuse blown on the slide adjust module, or other mechanical failures.
Slide Adj. Sw. Fail Slide adjust switch failure. If the main 5000 control reports to the auto-setup
card that the slide adjust switch is ON but no AC voltage is detected at the
slide adjust relays this error will be generated. It is also generated if the 5000
reports slide adjust switch OFF but the auto-setup module does see AC
voltage at the relays.
Up Relay Open The “Up” solid state relay on the slide adjust module failed open. Indicates a
hardware failure of the relay.
Up Relay Shorted The “Up” solid state relay on the slide adjust module failed shorted. Indicates
a hardware failure of the relay.
Down Relay Open The “Down” solid state relay on the slide adjust module failed open. Indicates
a hardware failure of the relay.
Down Relay Shorted The “Down” solid state relay on the slide adjust module failed shorted.
Indicates a hardware failure of the relay.
Lock Relay Open The “Lock” solid state relay on the slide adjust module failed open. Indicates
