LINK Systems OmniLink II Press Automation Control - Manual (Page 90)

August 30, 2002 Manual Version 1.0 5.7
Section 5.2.5 Auxiliary Equipment Messages
The OmniLink II Press Automation Control makes optional provision to wire inputs to its parallel port
on the back of the operator terminal from the intelligent controller (such as a PLC) of auxiliary
equipment so that diagnostic messages from auxiliary equipment can be displayed on the brake monitor
screen of the operator terminal. The messages are entered in the configuration menu as detailed in
Section 4.2.5. When this option is used the messages appear under the Auxiliary Equipment Messages
legend on the Brake Monitor and Diagnostic screen.
Section 5.2.6 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. The only reasons for the stop of press stroking that the OmniLink II Press Automation Control
can display under Reason for the Last Stop are those for stops that it initiates. Because it monitors the
voltage to the valve that controls the clutch and brake, the OmniLink knows each time the press stops
stroking. If it initiated the stop, the reason that it initiated the stop will be displayed. Stops that are not
the result of the OmniLink will result in a display of “Non-OmniLink II Stop” under Reason for the
last stop.
Additional information concerning press stops is archived in the Event Log. See Section 5.2.8.
Section 5.2.7 Present Running Status
The Present Running Status message indicates in English (or Spanish) any current condition of the
OmniLink II Press Automation Control that results in a stop output to the press control and
prevents stroking. Any condition that prevents stroke initiation is displayed as long as it exists. If no
stop condition exists, an “OK” message indicates that only the correct run buttons are required to
initiate the stroke.
The OmniLink II Press Automation Control cannot show any reason why the stroke may not be initiated
caused by the press control or other equipment.
Section 5.2.8 Diagnostics
Additional OmniLink diagnostics are available through the DIAGNOS softkey. Pressing the DIAGNOS
softkey will result in the main Diagnostic screen appearing as shown in Figure 5.4. This screen shows:
• The states of the four outputs available on the R/D-Brake Monitor Module, including the two
module PLS outputs.
• The state of the two inputs for the R/D-Brake Monitor Module, including the optional input to
indicate whether the press control is in a setup or production mode is shown.
• The state of the output relays that provide stop signals to the press control.
• Raw analog input signal information from the R2D decoder and the optional speed input, analog
speed output and % Motor Load input.
