Manual control of output
The EKE 347 controller is used for regulation of
the liquid level in:
• Pump reservoirs
• Separators
• Intermediate coolers
• Economisers
• Condensers
• Receivers
The controller is communicating with a
transmitter that continuously measures the
liquid level in the actual reservoir.
By comparing the measured value with the
level setpoint entered by the customer, the
controller dictates the valve to increase or de-
crease the liquid flow to or from the reservoir.
•
Limitation of Opening degree possible
•
ON/OFF operation with hysteresis
•
Programming menu with 3 access levels
and separate passwords
•
Connection to other EKE 347 controllers
possible
•
Wired remote display possible
•
BUS communication:
- CAN Bus (Danfoss internal only)
- MODBUS RTU RS485 for communica-
tion with e.g. PLC
