Unitronics UIS-04PTN User Manual page 12

Notes:
1. The UIS-04PTN and UIS-04PTKN measures values that are slightly higher or lower than the nominal
input range (i.e. 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 help for details) as well as by the respective
input LED (see LED Indications), while the input value is registered as follows:
Fault Type
Overflow
Underflow
Connection fault
2. The UIS-04PTN and UIS-04PTKN inherently supports 3-wire sensors.
4-wire sensors may be connected by utilizing 3 of the sensor wires; in-order to achieve the
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 UIS-04PTN and UIS-04PTKN installation guide for detailed installation instructions.
3. 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.
4. Step response and update time are independent of the number of inputs that are used.
5. See LED Indications Table above for description of the relevant indications. Note that the
diagnostics results are also indicated in the I/O tags and can be observed through the UniApps™
or the online state of the UniLogic™.
6. Sensor connection fault check is active by default for both temperature and resistance
measurements.
7. Sensor connection fault check may interfere with some test equipment like resistance/RTD
simulators and thus may induce reading errors or cause malfunction of the test equipment and/or
the UIS-04PTN and UIS-04PTKN.
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 UIS-04PTN and UIS-04PTKN will not check, or report, connection
faults; thus, the reading in such case is unpredictable.
