Description
The controller makes it possible to control directly actuated axial fans with AC or DC motors (50 or 60 Hz) using an algorithm that changes the speed, if necessary, based upon the entered target value and pressure and temperature data. Thanks to the latest technology and optimised software, the pressure can be controlled by entering temperature values. The display functions as a manometer at the same time. The controller consists of two parts:
Electronics with EPROM and power board for installation in a control cabinet or separate housing
Operator panel with communication display for installation in the control cab door
ATTENTION:
The operator panel is NOT included and must be ordered as a separate accessory (EDV number 297.4504).
Operation is possible without the operator panel!
Operation and programming of the control is performed exclusively via the available operator interface. The display shows a text explanation for each of the inputs and a standard display indicates more precise information about the current operational status of the controller. It is possible to use the controller WITHOUT the operator panel. Advantages of the operator panel include:
- Plain text display of all programming processes
- Directly show the pressure ratios in the refrigeration circuit in °C
- Display the set target value (SET)
- Display the current power supplied to the fan in %

- Programmable refrigerant (material characteristics are programmed)
- Clear and concise operational display
- Direct pressure and condensation temperature control (can be used as HP manometer)
- ADR 80 and ADR230 for DC and AC
- ADR 70 and ADR 80 to 8A loadable per phase
- ADR 230 to 23A loadable per phase
- Start fans at 100% when initiating control. Regulation at a reduced value for 0-10 seconds can be entered
- Configurable minimum and maximum power from 0-100%
- Hysteresis to avoid motor clocking near limit values
- Configurable proportionality band dependent on control period start and end
- Two pressure transducers can be connected (ADR 80 & 230). Control action is based on the transducer returning the highest pressure
- Automatic determination of input voltage, i.e. AC or DC.
- Contact for bridging the controller and fan function at 100%
- Automatic control and monitoring of the cosj and adjustment of electrical controller to the value
- Display can be removed once programming and configuration is complete. This helps prevent changes being made by unauthorised persons.
