“Boot Program
Corrupt” The boot program failed its’ validity check. If this is not cleared by turning
the unit off and back on, then the unit needs to be sent to Link for repair.
“Boot Version
Mismatch” The boot information block reported a different version for the boot program
than reported by the boot program itself. If this is not cleared by turning the
unit off and back on, then the unit needs to be sent to Link for repair.
“Main Program
Corrupt” The main program failed its’ validity check. If this is not cleared by turning
the unit off and back on, then the unit needs to be sent to Link for repair.
“Module in Boot
Mode” Module is in a special boot mode. This should only be seen when the module
is being programmed from a program update card.
“One or More
Channel Errors” One or more channels have an error. This message is most often seen when a
tonnage alarm is active.
“Press Running At
Startup” The press was already running (clutch engaged) when the module powered up
and before it could get any of its settings. This is usually the result of a loss of
power to the module while the press is running.
“No Resolver Info” No resolver information (for the crankshaft angle) was received from the press
control or brake monitor for an excessive length of time. This is usually the
result of an intermittent connection of the high speed bus wiring.
“Total Alarm” A “total alarm” has been tripped. See section 3.2.5.6 for information on total
alarms.
“Reference Shorted” The strain gage reference voltage (nominally 10 volts) is below the acceptable
value. This is almost always due to a shorted reference line (labeled “R” on
the strain gage connector) on one of the strain gages. Disconnect all strain
gages and press the RESET FAULT softkey to reset the error. If the message
does not reset then there is an internal fault on the module and it needs to be
returned to Link for repair. If it does reset, plug the strain gages back in one
at a time to determine which gage is causing the problem. With the strain
gage unplugged, the normal resistance between the reference and common
(“R” and “C”) of the gage (not the module) is approximately 350 ohms.
“24 Volts Shorted” The +24 volt line for powering external sensors (with the 5100-8C option) is
drawing excessive current. If unplugging this connection does not allow the
condition to be reset, then there is an internal fault on the module and it needs
to be returned to Link for repair.
Communication
Failure The operator terminal has lost communications with the tonnage monitor
module. This could be because of a loss of power to the module, a wiring
problem with the high speed bus cable, or a hardware failure of the tonnage
monitor module or operator terminal.
