To resolve fluctuating ∆p (differential pressure) values in the RECO EasyLine RM-216 C, check and adjust hose connections and set different values for ∆p control. This helps stabilize the ∆p readings and ensures proper cycle operation.

@BABLY KUMARI MAHATO
The output signal value ( 4-20 mA) has fluctuations only not the actual dp value... the display has almost stable dp value but the output current is fluctuating.

RM-216 C.10 Easy Line Documentation 1 Safety instructions The filter control system RM-216 C when connected to the mains poses an electrical hazard. Device failure, serious or even fatal injuries may occur as a result of improper installation of the connected equipment.
RM-216 C.10 Easy Line Documentation 3 Assembly 4 “Step by step” installation Supply voltage connection A separate power supply unit is recommended for the operation of the filter controller with extra low voltage. The unit can be operated with a supply voltage of 24 V DC, if no expansion modules are connected and if the electric cables (minimum cross-section: 0.75 mm²) to the solenoid valves are shorter than 10 meters long.

RM-216 C.10 Easy Line Documentation DTC mode 1 The down time cleaning is started via the contact connected on input E1 and E2. If the fan is switched off, the contact on E1, E2 must open. DTC mode 2 The down time cleaning is only started via the contact connected to input E1 and E2 if the differential pressure has exceeded the value ∆p DTC max during operation.
RM-216 C.10 Easy Line Documentation DTC mode 3 The down time cleaning is started when the differential pressure falls below the value ∆p DTC min, after the value ∆p DTC max has first been exceeded. The signal on input E1, E2 is ignored. 6.4 Cleaning via start/stop input (external ∆p switch) If the cleaning is controlled via an external ∆p switch, the isolated contact on the ∆p switch must be connected to the start/stop input D1, D2 (terminals 12, 13).
