Incorrect temperatures
could be the result of the following:
• Values such as -9999.9 in the case of a sensor short circuit or 9999.9 in the case of a sensor
lead break may not be the result of a material or termination error. Is the correct sensor type
selected in the input menu (KTY, PT1000, RAS, GBS, etc.)?
• A sensor can also be checked without a tester simply by swapping the sensor that is proba
-
bly faulty with one that works at the terminal strip and checking the temperature display. If
the error is reproduced, the problem is the sensor. However, if the problem remains on the
same input of the device, the fault is either due to the sensor type setting or the input itself is
faulty (such as faulty surge protection).
Table of resistances of various sensor types
If the sensor is faulty, note the sensor type when replacing. While it is possible to use a different type
of sensor, the parameters for that input also have to be set to suit the type of sensor used.
The current standard type used by Technische Alternative is PT1000.
KTY (2 kΩ) was the standard type until 2010/2011.
Manual switching of an output not possible:
• Ensure that output 6 is generally potential-free and therefore does not carry live voltage. Aux
-
iliary relay outputs may also be potential-free. It is thus only possible to directly switch a 230
V consumer when the appropriate wiring has been implemented.
• If it is not possible to switch the output ON or OFF in manual mode, a message may be active
at that moment which switches the corresponding output dominantly ON or OFF (red frame
around the output symbol; indication of the message in the upper status bar). Subject to pro
-
gramming and user status, manual mode is not possible in this case.
Troubleshooting – hardware
In a clear case of a hardware fault, please return the device to your retailer or the manufacturer for
repair. In this case it is essential to include a fault description with the device (simply stating "the de
-
vice does not work, please repair" is insufficient). Processing is accelerated if an RMA number is re
-
quested via our homepage www.ta.co.at.The defect must be clarified with our technical support
beforehand.
