CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) DIP switches: Check the output range selector setting.
3) Power input: Check the power input voltage.
4) Input: Check voltage across the terminal A – B with a
sensitive voltmeter (With 20°C or 68°F, approx. 110mV
with Pt 100, approx. 55mV with Pt 50 Ω).
If RTD wires are broken, the output goes over 100% (be-
low 0% with downscale) due to burnout function. Con-
firm the status indicator LED pattern and check lead-
wires in such a case.
5) Output: Check that the load resistance meets the de-
scribed specifications.
6) Status indicator LED: Check that it blinks in a regular
pattern.
