Relays, Extended Upper Limit

When the set-up is complete, the near and far relays toggle at the respective near and far set points.

The relays operate in a fail-safe manner. Specifically, the NEAR relay is ON unless the near limit is

encroached. The FAR relay is ON unless the target drops below the far limit.

In feed applications, it is sometimes useful to move the near relay's activation point above the top of

the control range. The near relay is used to stop the leader process when the feed device isn't keeping

up. If the full 10VDC or 20mA signal is required to synchronize the feeder with the process, nuisance

trips transpire.

To use this feature, press the S2 and S3 buttons simultaneously. The lights above these buttons turn

ON. Place a target where the desired near relay trip should occur. Press the S2 and S3 buttons

simultaneously again. The LEDs above the buttons will go out, and the near limit will have moved to

the new location.

Program Lock Out

As previously mentioned, the W1 jumper must be in place to manually program the system. When it is

removed, programming the system manually is not possible. This may be useful in plants where only

authorized personal are allowed access to machinery set-up.
