through I.11. The brake control board of the controller opens a solid-state relay contact for the
normal stop signal to the press control.
STOP MAIN MOTOR FAULT (OUTPUT):
The stop main motor fault signal from the controller to the press control requests an emergency
stop condition. The press control then stops the main motor, sets the flywheel brake, sets the
friction brake and removes the enable signal. The controller is placed in the fault mode and sets
the eddy current brake to help stop the press. The brake control board of the CES controller
opens a solid-state relay contact (LED On) for the stop motor fault signal to the press control.
This signifies a 100 Level Fault.
STOP NOW FAULT (OUTPUT):
The stop now fault signal is an output from the controller. It indicates a second level of
emergency stop in which the press control is to immediately remove the enable and set the
friction brake the software programs the reference to zero which applies the eddy current brake to
help stop the press. The brake control board of the controller opens a solid-state relay contact
(LED On) for the stop now fault signal to the press control. This signifies a 200 Level Fault.
STOP-ON-TOP FAULT:
The stop-on-top fault signal directs the control to complete the present cycle, and then execute a
normal stop-on-top, after which the controller is in the fault mode. The brake control board of the
CES controller opens a solid-state relay contact (LED On) for the stop-on-top fault signal to the
press control. This signifies a 300 Level Fault.
CONTROL FAILURE FAULT (OUTPUT):
The control failure fault is generated by either of two conditions. One is when the main
microprocessor watchdog timer senses a microprocessor failure. The other is when the
secondary clutch brake controller faults. The brake control board of the controller opens a solid-
state relay contact (LED On) for the control failure fault signal to the press control. Either failure
means loss of control, so this is treated as a stop now 200 Level fault.
CLUTCH ON (OUTPUT SIGNAL):
The clutch on output is a 115-volt output (voltage provided by the press control). This signal
allows the press control to monitor the run state of the controller.
The contactor is activated by the following conditions:
Brake contactor is ON
Enables are present
No fault is present
Clutch contactor ON signal is present
Note: if the brake contactor drops out or clutch ON is removed, The clutch contactor will drop out
after the timed brake delay timer or if the press control drops the control clutch on signal. .
9.3 PRESS CONTROL INTERFACE - SERIAL PORT
The serial interface assembly makes it possible for the controller to communicate with another
microprocessor or a main computer. This communication link is an RS-422 assembly that is connected to
Terminals 91 through 94. It can be utilized to set references (i.e., speeds and angles) and to
communicate diagnostic information, faults, etc. See next section for detailed Information.
