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 ∆p max 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 ∆p min 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 ∆p max 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 ∆p max 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

page 7 and section 5.3 "Setting parameters".
5.2 Display and setting elements
This LED flashes if one of the following alarms is triggered:
∆p min alarm
Differential pressure has fallen below the set ∆p min alarm switch point (in the case of the ∆p
control device function) or has exceeded it (in the case of the ∆p monitor device function).
∆p max alarm (the set ∆p max alarm switch point has been exceeded)
