Description 0-10 V Outlet; Status Signal - M&C PMA Series Instruction Manual

13.3.6

DESCRIPTION 0-10 V OUTLET


0-10 V always correspond to 100 % O

For a load of > 100 KOhm

Linear from -0.5 V to 11 V
General evaluation of the 0-10 V signal:
Measuring Range
Lower deviation
The connection happens at the 9-pole D-sub-connector X4. (see figure 6 and 7)

STATUS SIGNAL

The status signal contains a collective fault message:

Power supply error, voltage breakdown

Flow min. fault

Flow max. fault (can be switched off: JP3)

Light source short circuit/line breakage

Selection switch defective

Transmitter temperature < 45 °C/> 60 °C (can be switched off: JP8/JP7, 2+3 on, 1+2 off)

Coupling state (can be switched off: JP6, 2+3 off, 1+2 on)

Fault High/Fault Low (connectible: JP14/JP12). Measuring range lower deviation and exceedance
more than +3.125 % resp. -4.375 %
An allocation of the existing failures is possible via 12 internal LED's on the main board (see figure 12). The board
becomes visible after removing the cover plate. To do this remove the two screws in the lid.
The status signal is accessible via a potential free switching contact (status contact) as well at X1 (D-sub 25-
pole) as also at X4 (D-sub 9-pole) (see figure 6 and 7).
