Page 4: General Description
EC3020 General description General description The EC3020 controller is used for the fully automatic monitoring and control of single or duplex cylinders for exchange cylinder systems, whereby the filter cylinders have to be regularly exchanged. The basic controller parameters can be changed at any time; the programmed values are not lost in the event of a power failure. -
Page 5: Step "Service Filter 1", "Standby Filter 1
EC3020 General description Step "Service Filter 1”, “Standby filter 1” Filter cylinder 1 produces demineralised during “Service filter 1”. As an option, it is possible to regulate the Service valve by 1 or 2 level switches. If 1 level switch is set, the Service valve is opened after a delay, which can be programmed. -
Page 6: Step "No Service
EC3020 General description The following values are monitored Conductivity under the minimum limit value (only if the service valve is opened) The maximum conductivity limit value (from version 1.01.02 only if the service valve is opened). Inlet tank low level Inlet tank high level Step "No Service”... -

Page 10: Alarm
EC3020 Alarm Alarm If the alarm relay is activated, it can be deactivated by pressing the external key. Although this deactivates the relay, the message is still shown in the LCD display. Press the key again to remove the message. -
Page 11: Exchange Cylinder
EC3020 Alarm Exchange cylinder 1 Exchange Cylinder 1 This message appears if filter 1 has produced water with too high conductivity and the filter cylinder needs to be exchanged. The message is not programmable and is always transmitted to the alarm relay. -
Page 12: Exchange Cylinder 1+2
EC3020 Alarm Exchange cylinder 1 +2 Exchange Cylinder 1+2 This message appears if both filters shortly after one another produce water with too high conductivity and the cylinders of these filters need to be exchanged. When switching on the system by hand, filter 1 will be engaged first. -
Page 13: Input Functions
EC3020 Input functions Input functions The inputs ‘storage tank empty’ (EM), ‘storage tank full’ (FU) and ‘Alarm reset’ (IN) are included as standard. Tank full / Tank empty The input functions ‘Tank full’ (FU) and ‘Tank empty’ (EM) are used for the automatic filling of a storage tank. - Page 14 EC3020 Input functions Conductivity probe The connection for the conductivity probe is indicated by ‘CC’. The measurement range of the conductivity probe depends on the cell constant. The cell constant can be programmed in step 2.1. Also, it is possible to set the minimum and maximum limit values with a programmable delay time.

Page 15: Output Functions
EC3020 Output functions Output functions The outputs ‘Service valve 1’ (IV), ’Service valve 2’ (PU) and ‘Alarm’ (AL) are included as standard. Service valve 1 Service valve 1 is opened if the first filter is activated and, possibly dependent on one or more level switches, demineralised water must be produced. - Page 16 EC3020 Changing and calling up the basic parameters Changing and calling up the basic parameters On taking the controller into operation, the operating values of the reverse osmosis system are set by entering the basic parameters. These values can be changed at any time, but will not be lost in the event of a power failure.
- Page 17 EC3020 Changing and calling up the basic parameters 1. Language Step no.: Nl E The language can be set in the step. 2. Number of filters Step no.: No. of filters 2 Enter the number of filters installed in the system.
- Page 18 EC3020 Changing and calling up the basic parameters can erroneously result in very low conductivity values. For monitoring purposes, a limit value of 0.0 to 999 μS/cm can be entered. Step no.: Delay After a programmed delay time of 1 to 9999 seconds, a drop below the limit value will result in the error message ‘Value CD Min below the limit value’...
- Page 19 EC3020 Changing and calling up the basic parameters 4. Temperature Step no.: Temperature 25°C By entering the water temperature, the indicated conductivity value can be compensated to allow for the current temperature. The conductivity measurement is based on a water temperature of 25 °C. In case of a higher or lower temperature, this can be compensated by hand.
- Page 20 EC3020 Changing and calling up the basic parameters 6. Level switches Step no.: Level switch Refilling of the storage tank is controlled with the aid of level switches. Level switch = 1 : The storage tank is immediately refilled if the level of the water drops below full. A maximum quantity is always available.
- Page 21 EC3020 Changing and calling up the basic parameters 7. Alarm Step no.: MI-PF- In this step, you can program the events that will activate the alarm relay (“-“ = not activated, “|“= activated). = minimum conductivity = power failure Step no.: Rel.energ.

- Page 23 EC3020 Connection terminals Installation and commissioning General Installation and commissioning of the control system may only be carried out by trained specialists who are familiar with these operating instructions and the applicable regulations on safe working practices and accident prevention. The instructions given in this manual must always be observed and followed.
- Page 24 EC3020 Connection terminals It is not permitted to connect the potential-free relays with a combination of 230 VAC and extra low voltage. Some external relays, magnetic switches, solenoid valves, etc. can cause unwanted interference pulses when switched off. For this reason, it is recommended that the components mentioned should be equipped with a so-called RC network in advance.
