5. OPERATION
The MicroLink system has built-in counters, job
information storage, diagnostics, and auxiliary
equipment communications. The screen shown in
Figure 5.1 is the main options screen for the
MicroLink system. This screen is the starting
point for going to any of the system screens. The
chart in Figure 2.2 shows the connections between
screens. This chapter describes the operation of
the counters and the job information storage and
recall. The access code system is explained in
Chapter 6 and the diagnostic features are covered
in Chapter 7. The auxiliary equipment
communications are explained in the separate
Feed Interface Manual and the MultiSet system is
covered in the separate MultiSet manual.
Figure 5.1: Main Options Screen
5.1 Counters
The MicroLink system uses an input to indicate
the top of the stroke. This “
Top ” input is used by
the system to count strokes of the press. The
“
Counter ” screen is reached by pressing the soft
key next to the “ Counter ” label on the main
screen. After this soft key is pressed the screen
will look similar to Figure 5.2.
This screen has five counters that can have three
properties. The “
Quantity ” is the number of
strokes that the press has made. The “ Limit ” for a
counter is the quantity at which the MicroLink
system will assert its top stop relay. This will stop
production when the required number of parts
have been made.
The stop condition will be output in one of two
ways. If there are no air adjust board or no air
adjust and slide adjust boards installed, the stop
relay in the MicroLink terminal will be used to
signal the stop. The wiring of this relay is
described in Section 3.2. If there is an air adjust
board or an air adjust and slide adjust board
installed, the Top Stop relays whose contacts are
accessible on the terminal strip located on the
back access cover will be used to signal the stop.
Figure 5.2: MicroLink Counters Screen
The “ State ” of the counter determines whether the
quantity will be updated when a press stroke is
made. If the state is set to
“On” then the counter
increases normally, but if the state is “Off” then the
counter does not change.
The current quantity of any counter, except the
stroke counter, can be set to zero by pressing the
Clear Counter soft key.
The Clear Tripped soft key only appears when a
counter has reached its limit. This soft key will
reset the counters that have reached their limits
and that are in the
“On” state. Pressing this soft
key also removes the stop output for the counter
limit, which allows the press to be returned to
production
The limit, quantity, and state parameters can be
changed with the RUN/PROG key or an access
code (depending on access code set up). This
allows the supervisor to control who can change
these parameters. Use the arrow keys on the
keypad to position the blinking cursor on the item
that you wish to change and press the appropriate
