Configure the Auxiliary input to show the readings for the attached
sensor. In addition to the default setting of ±10 V, up to five custom
sensors can be configured and selected for the Auxiliary input
channels.
To configure custom sensors:
1. Select one of the five custom sensors.
2. When the sensor has not been configured, push  (Edit) to
access the configuration screen.
3. Use the configuration screen to specify a name, sensor type, unit,
gain, and offset. Confirm the settings with
 (Back).
4. Select the sensor for the Auxiliary input with .
The configuration includes name, sensor type, unit, gain and offset:
• Change the Name from Custom1...5 to any clear identification of
the sensor with up to 16 characters.
• Select the Sensor Type from a list that includes 0-1 V, 0-10 V,
4-20 mA, and other.
Use the 0-1 V and 0-10 V settings for sensors with a voltage
output directly connected to the Aux input. The commonly
used sensors that provide an output current of 4-20 mA can
be used. In this case, an external resistor parallel to the Aux
input (+) and Aux input (-) is required. A resistor value of 50 Ω
is recommended. Resistor values >500 Ω are not supported.
The resistor value is entered in the sensor configuration dialog
and is a convenient method for configuration of the sensor
measurement range.
• Use up to 8 characters to configure the measurement Unit of the
parameter.
• Configure the gain and offset. For sensor types 0-1 V, 0-10 V, and
4-20 mA, the Gain and Offset are automatically calculated with
the measurement range of the sensor. In the Minimum field, enter
the measurement value that the sensor supplies on the output, 0 V
for 0-1 V and 0-10 V sensors or 4 mA for 4-20 mA sensors. In the
Maximum field, enter the measurement value when the sensor
supplies 1 V for 1 V sensors, 10 V for 10 V sensors, or 20 mA for
20 mA sensors.
For all other sensors types, use Other. For this sensor type use a gain
and offset.
Example 1:
Temperature sensor ABC123
Measurement range: -30 °C to 70 °C
Output: 0-10 V
The configuration for this sensor looks like this:
- Name: Change the name from Custom1 to ABC123 (°C)
- Sensor Type: Select 0-10 V
- Unit: Change Unit1 to °C
- Minimum: Enter -30
- Maximum: Enter 70
