Sensor Mapping
The ITLS and ITLSC1D2 models provide the owner
with customizable sensor mapping. This becomes a
very powerful and desirable feature when the owner
needs added flexibility in controlling the circuit outputs
beyond the standard single sensor input.
1. Sensor Mapping is the assignment of one or more
Sensor Inputs to one or more output circuits.
Sensor (Input) Mapping is accessed via the Sensor
Mapping Menu.
Sensor Mapping
Ambient or Line Sensing, Single Sensor
A single sensor (RTD) may be mapped (or linked) to
multiple output circuits. This allows several circuits to
be controlled by a single sensor.
Minimum, Maximum, Averaging
Several sensors may be mapped to a single output cir-
cuit. This allows a single circuit to be controlled by the
minimum, or the maximum or the average temperature
of all of the sensors mapped to that output circuit. This
may be desirable on long runs or zones which realize
varying temperatures or weather conditions at different
times of the day.
This does not apply when only 1 Input/Circuit selection
is made from the Order Table.
Multiple Sensor Mapping
A single sensor may be used independently or com-
bined with other sensors to control more than one cir-
cuit.
For Example:
The average temperature of Sensors 1, 3 and 5
is used to control Circuit 1 while simultaneously
the maximum Temperature of Sensor 3, 4 and 5 is
used to control Circuit 2.
Combining Sensing Types
The owner may need to have multiple line and/or am-
bient sensing control scenarios occurring simultane-
ously.
For example, these may be occurring simultaneously:
1. Circuits 1, 2, 3, 4, and 5 are all controlled by a single
RTD (Sensor 1) that is sensing the ambient temper-
ature (Ambient Sensing)
2. Circuit 6 is controlled by Sensor Input 2 which is
strapped to a process pipe. (Line Sensing)
Sensor mapping is accomplished within the Sensor
Mapping Menu. See Figure 8.
