In this case, you would choose

the Resistance (ohms) Custom

option.

Another example would be that

of a Pressure Sensor. In Figure

50, the chart shows a Pressure

value that corresponds to a Volt-

age Value.

Figure 50

In this case, you would choose

the Voltage (V) Custom option.

If your data sheet does not come

with a chart, but rather gives

you an equation to use, you

will need to calculate the input

values based on the equation

variables.

2) Choose a Pull-up Value.

The values available are 10K

ohm, 1K ohm, or None. To help

determine which pull-up value

to use, refer to the following

rule of thumb:

-3 wire sensors: None

-2 or 1 wire sensors: 1K or 10K

If for example your sensor is a

single wire Temperature sensor,

and is rated as 1K @ 25C, you

would want to use a 1K pull-up.

You want to match your pull-

up value as close to the sensor

rating as possible.

3) Set the alert value according

to your speciﬁ c sensor.

Depending on the sensor, the

alert value will be either a maxi-

mum or a minimum value.

For example, if you have a pres-

sure sensor, and you want the

CTS to alert you when the sen-

sor reads greater than or equal

to 90 psi, set up the values as

shown:

1 2 ... 25 26 27 28 29 30 31 32 33 34 35 36
