specified performance, all sensor wires shall be of identical type and length just as with a 3-wire
sensor connection.
2-wire sensors may also be connected; performance in this case will degrade because of the
wires` resistance.
Refer to the controller installation guide for detailed installation instructions.
11. The controller temperature inputs measure values that are slightly higher or lower than the
nominal input range (Input Over/Under-range respectively).
Note that when input Overflow, Underflow or a connection fault occurs, it is indicated in the
corresponding I/O Status tag (refer to the UniLogic
input LED (see LED Indications), while the input value is registered as follows:
Fault Type
Overflow
Underflow
Connection fault
12. For temperature measurement, the value is represented in 0.1° units. For example, a temperature
of 12.3° is represented as 123 at the Value tag.
13. The overall accuracy for thermocouples is a combination of the per-sensor specified accuracy and
the thermocouple cold junction error specification.
14. Sensor connection fault check is active by default for temperature, resistance and mV
measurements. This may interfere with some test equipment like RTD, thermocouple, resistance
and voltage simulators and thus may induce reading errors or cause malfunction of the test
equipment and/or the controller.
In order to interoperate correctly with such equipment, you may set the Disable Fault Detection
I/O tag. This will disable connection fault check for all inputs.
Note that when this tag is set, the controller will not check, or report, connection faults; thus, the
reading in such case is unpredictable.
15. Life expectancy of the relay contacts depends on the application that they are used in. The
product's installation guide provides procedures for using the contacts with long cables or with
inductive loads.
16. Outputs O0 and O1 can be configured as either normal digital outputs or as PWM outputs. PWM
outputs specifications apply only when outputs are configured as PWM outputs.
17. The controller analog outputs are able to output values that are slightly higher or lower (if
applicable) than the nominal output range (Output Over/Under-range respectively).
18. This refers to the CONFIRM button on the controller USB Actions; press it if the indication requires.
