5.3 Function Input Pins

5.3.1 Overview

To use a Function Input pin (9, 10, 11 or 21), connect it to the DGND (pin 19) momen-

tarily. This can be accomplished by a push button switch, relay contact closure, or

PLC output.

Usually, the Function Input pins perform the default actions described in the “System

Connector Pinout” on page 36. However, a SensoCode program running on a Mathe-

matics Virtual Channel may replace these default actions. Consult the Customer

Information Sheet included with your instrument for details.

5.3.2 Example

For example, assume that you wish to use Function Input #3 to tare all channels in the

instrument simultaneously. Connect a push-button switch as shown below.
