Section 6.1.2 Operator Station Selects
These inputs define the active operator stations for Single Stroke, Continuous, Automatic Single Stroke,
Continuous on Demand, and Maintain Continuous modes. They may define the stations for Inch, Timed
Inch, and Setup/Stop Time Test modes if the control has been configured to use these stations. An open
input (0 volts) selects the station to be active, and an input of +24 volts de-selects the station. A stroke
may not be initiated until all active operator station buttons are pressed, and all inactive stations de-
energized. The press control generates an immediate stop if any inactive station is pressed. The input
labeled "Operator Station #4 Control Type" configures operator station #4 as either Palm Buttons or a
Foot Switch. An input of +24 volts indicates that station #4 is being operated with palm buttons, and 0
volts indicates a foot switch. This input must be a permanent strap on the input card installed when the
press control is configured. Appropriate Warnings must alert the operators as to how this station
functions. If configured as a Foot Switch and the station #4 select line is +24 volts, all other operator
stations must be inactive. The Foot Switch functions only in Single Stroke and Maintain Continuous
modes.
Section 6.1.3 Prior Action Setup Buttons
The Continuous, Automatic Single Stroke, Continuous on Demand, and Maintain Continuous modes
require the correct setup button be pressed before stroking can be initiated. The setup button must be held
closed (+24 volts) for approximately 1/2 second, at which time the press control will allow 6 seconds for
stroke initiation to take place. If all active operator station run buttons are not pressed in the allocated
time, the press control will automatically time out the setup action. The mode can not be setup again until
all operator buttons and setup buttons are released.
Section 6.1.4 Top Stops
A low level (input open) on these inputs cause the press control to stop the next time crankshaft angle
reaches the top of the stroke, if any occur while the press is stroking. They prevent the machine from
being started anywhere in the stroke, until they are cleared (returned to +24 volt).
Section 6.1.5 Emergency Stops
A low level (input open) on these inputs cause the press control to stop immediately, and prevent stroke
initiation until they are cleared (returned to +24 volt). Emergency stop button contact 1 and contact 2
inputs are intended to be wired to the same switch. These inputs must track each other within an
allowable time or a fault is generated. Master Stop input #48 is shown as an emergency stop because it
causes the press control to initiate an immediate stop but not open the LMC relay. A separate contact on
the master stop button is used to remove 120 vac power to the motor start circuit.
Section 6.1.6 Master Stops
A low level (input open) on these inputs cause the press control to stop immediately. In addition they
cause the press control to turn off the LMC Relay output and prevent stroke initiation until they are
cleared (returned to +24 volt).
