Chapter 3. Sensors

name and/or connections diagram under the sensor menu to determine the correct slot position for the
sensor input card. There will be numbers appearing at the end of the sensor name like PC 1.1 or PC

1.2. A designation of 1.2 indicates the sensor input card is located in slot #2, whereas a designation of
1.3 indicates slot #3. If the numbers which appear begin with 5 (e.g. PC 5.1), then it means the sensor

input card is located in slot #1 of the expansion module. The slot position in which the sensor input
card is located can also be verified by going to the connections diagram under the sensor menu as
described in the Connections section of this manual.
