2-Wire C.L. Sensor Setup
The 2-Wire C.L. (Current Loop) (Type A) Sensor Setup function allows you to enter information about 2-Wire C.L.
(Type A) Sensors installed at your site. You must enter data individually for each sensor.
Selecting the 2-Wire C.L. Sensor Setup Function
To select 2-Wire C.L. Sensor Setup, press FUNCTION until you see the message:
Press STEP to continue.
2-Wire C.L. Sensor Configuration
If necessary, press STEP until you see the message:
Use this display to tell the system which sensor positions on a module are connected to 2-Wire C.L. sensors.
NOTE: If 2-Wire C.L. sensors are not installed, this function is not available.
HOW THE SYSTEM CONFIGURES 2-WIRE C.L. SENSORS
If 2-Wire C. L. sensors are installed, the system recognizes the presence and module slot locations of Type A
Interface Modules. The system also establishes a module number based on the slot location. For example, if
modules are installed in slots #3 and #6, the module in slot #3 automatically becomes module #1 and the module
in slot #6 becomes module #2.
As you specify which sensor positions on a module are connected to 2-Wire C.L. sensors, the system establishes
a number for each sensor. For example, if there is a 2-Wire C.L. sensor in positions 3 and 5 of module 1, the
sensor in position 3 becomes C3 and the sensor in position 5 becomes C5.
To indicate that a 2-Wire C.L. sensor position is connected, choose the number corresponding to that position. For
example, if the position is 3, choose 3 for the position. To indicate that a position is not connected, choose X for
that position.
SPECIFYING 2-WIRE C.L. SENSOR POSITIONS
To specify whether the first position is connected, press CHANGE until the correct choice appears (1 if the
position is connected, X if it is not). Press the Right Arrow key to move to position 2 and press CHANGE again
until the correct choice appears. Repeat these steps until you have correctly specified all sensor positions. When
you have entered a choice for all positions, press ENTER to confirm your entry. The system displays the following
message:
