Section 4.2.7 Reason For The Last Stop
Diagnostic information is provided to show the reason the press stops. Once a stroke is initiated, the first
stopping action is latched and displayed. This is done to capture transient conditions that may return to their
proper state after the press stops. This information remains latched until press stops again.
Additional information concerning press stops is archived in the Event Log. See Section 4.2.9.4.
Section 4.2.8 Present Running Status
Diagnostic information is provided to show any reason why the stroke may not be initiated. This information
follows the present conditions of the inputs. Any input that prevents stroke initiation is displayed as long as
it exists. If no stop condition exists, a "Ready To Stroke" message indicates that only the correct run buttons
are required to initiate the stroke.
Since the press control contains two microprocessors that make independent decisions about stop conditions,
the diagnostic area allows room for messages from channel A and channel B. If both channels report the same
event, the message is displayed on one line with no channel designation. If different stop conditions are
reported, each message is prefixed with "CH A" or "CH B".
Section 4.2.9 Diagnostics
Additional press control diagnostics are available through the DIAGNOS softkey. Upon entry, the Input
Diagnostic menu is automatically selected.
Section 4.2.9.1 Input Diagnostics
Figure 4.3 shows the input diagnostic screen. Each input is displayed with a number, description, and state.
The state indicates the voltage level (HI=+24 volts, LO=0 volts), and is shown for both channel A and
channel B separately. They are displayed in groups of eight and the operator can page through all inputs by
using the NEXT GROUP softkey. The input number will start back at one after all groups have been shown
or if the VIEW INPUTS softkey is pressed. The total number of inputs displayed is forty-eight for a standard
control or seventy-two if configured for the third input card. The third input card is available only when the
extended card rack is provided.
