Because the limit switch is used to start the examine period, it is
harder to tell if it is stuck in one position or the other. If the optional
IN-CYCLE program is installed, the Die Sentry provides a MODE of
OPERATION that requires any TIMED or CAM MODE limit
switches to be seen in both states (ON and OFF) on every press
cycle. To do this, the IN-CYCLE input must be wired to provide a
pulse every time the press completes a cycle. Refer to the section
of Operating the Die Sentry for more information on how to put the
Die Sentry into this Mode of Operation. If no checking is required
and the 50 part setup limit is not desired, the IN-CYCLE input need
not be connected.
DIE SENTRY OPERATION
This section deals specifically with using and programming a Die
Sentry. The front panel of the Die Sentry is described in detail first,
followed by general operation information.
The FRONT PANEL
A - Probe Status Area:
The Probe Status Area indicates the
current status of the five available probes. The first column of green
lights indicates that a given probe is ACTIVE. The second column
(Yellow lights) indicates that a limit switch for a given probe is
ACTIVE. The third column (Red Lights) indicates any probe faults.
For information on the operation of the probes, refer to the section
on PROBE THEORY.
B - Probe Selector Lights:
These lights display which probe is
currently being displayed or set.
C - Probe TIME/MODE Window:
The probe TIME/MODE window
is used to display the last time for the currently selected probe
when the key switch is in the RUN position. When the key switch is
in the SET position, the probe TIME/MODE window will display the
MODE or TIME setting for the currently selected probe.
D - SELECT Button:
This button is used to select a probe for
displaying or setting. The currently selected probe is indicated by
the probe selector lights. Pressing the SELECT button will step
through the probe one at a time.
E - ARROW Buttons:
The ARROW Buttons are used to select the
proper probe operating mode or to set the probe TIME settings.
F - RESET Button:
This button is used to reset any probe errors
that occur.
G - KEY SWITCH:
The key switch is used to switch between
SETUP Mode and RUN Mode. These modes are discussed under
Modes of Operation.
