GFK-0825F Chapter 5 Station Configuration 5-63
5
Enter the high span value for the channel. This is the actual voltage in millivolts to be scaled to the
high engineering units value.

Next, enter the actual voltage in millivolts to be scaled to the low engineering units value.

Span values are 16 signed integers ranging from -10,000 to 10,000. After entering the low span
value for the input, press the F4 (enter) key. Enter a high span value for the same input.

Alarm Limits
The next screen is used to set the low alarm limit for the channel in engineering units.

Each input channel can have a low alarm limit and a high alarm limit. Alarm limits can be set
anywhere over the dynamic range of the signal. The range for each is -32,767 to +32,767. The high
alarm limit must be greater than the low alarm limit. If alarm reporting is not wanted, alarm limits
can be set beyond the dynamic range of the signal so they will never be activated.
After entering the Low Alarm Limit, press the F4 (enter) key. Then enter the High Alarm Limit for
the channel.

That completes the configuration steps for one input channel on the 16-Point Grouped Analog
Voltage Input module. Continue as described above to configure the rest of the inputs.
