Extending Upper Limit
Another important feature on all new boards shipped after 7/15/14 is the ability to set an extended
upper limit for the relay. This feature allows the user to set the emergency stop function higher than the
original high point of the loop, thus increasing the amount of top-loop max feed time and minimizing
nuisance stoppage. To use this feature, press the S2 and S3 buttons simultaneously. This causes the unit
to enter a near relay setup mode, indicated by LEDs above S2 and S3 turning on. Place an object at the
new near point you would like to set, and press S2 and S3 together a second time. The LEDs above the
buttons should go out. To cancel the near relay set-up, press the S1 button, returning the unit to normal
parameters. Ensure that the lockout jumper (W1) is in place before you attempt to use this feature.
Offset
Offset bias is available and useful in some
situations. The graph at right explains what happens
when offset is employed. The standard control
signal is shown in blue in the foreground. Behind it,
the red shows the output of the CS-5000nwhen 25%
offset is implemented. Here, the output of the
control jumps to 2.5 VDC when the loop crosses the
long loop limit into the control range. The
discontinuity in the output may be useful when the
follower machinery must start rapidly. Since the
working slope is reduced, this feature is frequently
chosen in stamping operations with long feed
progressions. Feed 'wow' is reduced.
To set up offset, set DIP switches 1-3 in position to
implement the desired amount of offset. See the key
below. Using CSWin, offset as large as 50% may be
set.
