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 (∆pcontroller), 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.

More connections

Signal cables may not be run parallel to power cables.

Tighten all cable glands in use to ensure that the cables are properly enclosed and that protec-

tion rating IP-66 is guaranteed.

Cable glands that are not in use must be closed or replaced with blank plugs.

5 Step-by-step settings

5.1 Function in delivery status

The functions of a differential pressure dependent two-position controller and a differential pressure mon-

itor are active on delivery.

Two-position controller: If the increasing differential pressure exceeds the ∆pmax switch point (factory

setting: 900 Pa), relay contact 12, 13 closes and contact 11, 12 opens (see point on page 5). If the

decreasing differential pressure falls below the ∆pmin switch point (factory setting: 700 Pa), relay contact

12, 13 opens and contact 11, 12 closes.

Differential pressure monitoring: If the increasing differential pressure exceeds the ∆pmax alarm

switch point (factory setting: 1800 Pa), relay contact 18, 19 closes and contact 17, 18 opens (see point 

on page 5). If the differential pressure falls below the ∆pmax alarm switch point, relay contact 18, 19

opens and contact 17, 18 closes.

If another function is required or you want to activate additional functions, then you must change the pa-

rameter settings of the RM-DPC Micro FP. For more on this refer to points +"Configuration keys" on

page 7 and section 5.3 "Setting parameters".

5.2 Display and setting elements

"Alarm" LED

This LED flashes if one of the following alarms is triggered:

∆pmin alarm

Differential pressure has fallen below the set ∆pmin alarm switch point (in the case of the ∆p

control device function) or has exceeded it (in the case of the ∆pmonitor device function).

∆pmax alarm (the set ∆pmax alarm switch point has been exceeded)

RM-DPC Micro FP Documentation

RDN 10000531 7 13.05.2013

"Service" LED

This LED flashes if the set number of service hours has elapsed. This LED goes out when the

service hours counter is reset to 0 hrs. In order to do this, Parameter 10 "Maintenance

acknowledge ?" must be configured to "Yes".

"ON" LED

The "ON" LED is lit if supply voltage is present.

Configuration keys

Selecting a parameter:

Press and hold for more than 3 seconds. Then press

briefly to scroll up, or

to scroll down,

until you see the required parameter in the display.

Setting the parameter value:

Once you have selected a parameter, press

and hold for more than 3 seconds. Then press

briefly to scroll up, or

to scroll down,

until you see the required parameter in the display. Then press

and hold for more than 3 seconds to save the configured value.

Then, if necessary, press

briefly to scroll up, or

to scroll down,

and select additional parameters to configure or check.

Returning to "Operation" mode:

Press briefly.

The program automatically returns to "Operation" mode if no button is pressed in over

one minute.

Cancelling the parameter setting:

Press briefly. Then press

again briefly to return to "Operation" mode.
