1. Manual Set-Up

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.
