Configuration Level - PMA Digital 280 Mode D'emploi

CONFIGURATION LEVEL

In the Configuration Level, the indicator can be matched to the measurement task by
means of a 12-digit Configuration Code.The Code is displayed in three 4-digit Configu-
ration Words Con1, Con2 and Con3 (display alternates between symbol and value):

Ü Only with resistive sensors
* NO = Normally open: relay is energized on alarm
NC = Normally closed: relay is de-energized on alarm and opens the contact.
Ö Measured values below 400°C are outside the specified accuracy!
ä Only relevant for thermocouples and Pt 100.
# If measurement is below -99,9 °C, the decimal point must be adjusted to dP = 0.
< Always acts on LED for L1, also if the "Relay" option is not fitted.

Example for the adjustment of Configuration Word Con1: 0200 :
0200 means: Display in °C, input circuit monitor acts upscale / Pt 100 in 3-wire connection, range =
-200...650 / Relay is de-energized on sensor break, no measurement value alarm!
+ If the type of input signal is re-configured, all range-dependent parameters must be
matched to the new measurement range! ( r Deleting; page 12)

Pressing keys I and D changes the value of Con1 (the
longer, the faster). Pressing M stores the setting and Con2 is
displayed.
