E EKSRDS1A
Control and pump unit for solar systems
4PW56033-1
3.7 FlowSensor (optional)
• During installation be aware of the flow direction of the measurement instruments.
• The FlowSensor and the measuring section must not be overheated by welding and soldering work on
the plant. Only fit the measuring section after this work.
• Tighten the screwed fittings after final installation of the measuring section.
The FlowSensor EKSFLP12A (Page 9, Fig 2-6 ), available as an accessory, is
a measurement instrument that records the flow volume in the solar panels
and the feed temperature. The measurement range of the FlowSensor
EKSFLP12A is between 0 and 12 l/min (flow volume) and 0 to 120 °C (feed
temperature).
The measured values are shown on the control unit EKSR3PA display. The
control system EKSR3PA automatically sets the appropriate flow rate when
the system is in operation by regulating the speed of the solar panel circulation
pump.
1. Slide the swivel nut (2) and the cutting ring (1) over the pipe adapter (3)
at the outlet of the FlowSensor (4).
2. Push the pre-assembled FlowSensor (4) onto the flow connection of the
control unit EKSR3PA and tighten the swivel nut (2).
3. Lay the FlowSensor cable (5) between FlowSensor (4) and the control
unit EKSR3PA.
4. Connect FlowSensor cable (5) to FlowSensor (4) and to the control
system printed circuit board edge at position FLS (4-pin, see Fig 3-10).
