1 Safety instructions
When connected to the mains, the RM-DPC Micro FP differential pressure monitor is live and poses an
electrical hazard. Device failure, serious or even fatal injuries may occur as a result of improper installa-
tion of the connected equipment. In addition to the general safety regulations for equipment in industrial
electrical installations therefore, pay particular attention to the following points:
- The device may only be installed by qualified experts, in accordance with the provisions of
IEC 364, DIN VDE 0105 for electrical equipment.
- All applicable laws, conditions, rules and regulations governing the setting up of electrical equipment
must be observed in respect of the installation site.
- Equipment with protection rating IP00 without covers may only be configured by authorised expert
staff when disconnected and whilst observing the local safety and accident prevention regulations.
The RM-DPC Micro FP may only be operated in the permitted operating area.
Switch off the mains supply before replacing the differential pressure monitor or any compo-
nents connected to it. Otherwise the equipment may be damaged.
2 Equipment specification
The devices in the SensorLine RM-DPC Micro FP series are differential pressure controllers designed for
use in robust, industrial environments. They are used for measuring, visualising and controlling non-
aggressive, gaseous media in the excess pressure and insufficient pressure ranges.
All necessary functions can be configured and displayed simply using a text display with two-key menu
control. In operating mode, the text display shows the differential pressure in variable physical sizes. The
status messages ON / SERVICE / ALARM are also indicated by LEDs.
In addition to the controller functions for differential pressure, the software can also be used to allocate a
two-position controller (∆p controller), a differential pressure monitor and a time function. The full scale
output for the measured differential pressure can be set by the parameter 12 "dP range". The anlog out-
put signal is automatically adjusted to the set full scale output.
