Important
You must open the device to set the supply voltage and change the battery.
Changes should therefore be made before installation. Otherwise, you would
have to remove the MP85A process controller from the support rail.
6.1 Changing the supply voltage for active sensors
Use switch S1 to select either an internal 5 V supply or an external 24 V supply
(10 … 30 V
DC
, nominal 24 V
DC
) as the supply voltage for active sensors. The
factory setting is 5V internal sensor supply voltage.
To set switch S1, proceed as shown in Fig. 6.1.
