Page 12 Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Configuration Concept As a refrigeration contractor or a planning engineer you often have the problem to get the right cold storage controller that fits perfectly to your application. By using the TKP3130 this problem is no longer the issue, since this controller is designed to be universal. Its ‘free c o n f i g u r a b l e’ concept enables you to use it for almost all refrigeration applications.
PAGE 13
Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Page 13 Heating function Temperature sensors Two control sensors can be assigned to each circuit. If one of them gets warmer than setpoint plus hysteresis then cooling starts. Cooling doesn’t stop until both have achieved the setpoint. Cooling Cooling is controlled by switching the output relay. In case of power loss or controller defects the contacts must switch in a position which is safe for the application.
PAGE 14
Page 14 Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Temperature Alarm Any over- or undertemperature condition results in a temperature alarm which causes the normally energized alarm relay to de-energize. Hereby the N/O-contacts open and the N/C-contacts close. To avoid an alarm for short irregular conditions there is a delay time („warning delay“, setpoint page). The alarm condition is indicated by a LED at the front of the controller.
PAGE 15
Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Page 15 Analog Output Control Characteristic setpointdeviation The TKP / TKC contains an analog output which can be used for regulation or to provide a remote display with an actual value image. The signal is available as a DC-Voltage or a DC-Current-Signal.
PAGE 16
Page 16 Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Defrost The controller allows several, different defrost methods. This methods are available for each of the 4 possible control circuits, that means it is possible to assign 4 defrost relays. This relay output(s) then control an electric heater or fan for defrosting the evaporator(s). A defrost cycle can be initiated by different ways.
PAGE 17
Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Page 17 Intelligent Defrost (adaptive defrost) for walk-ins (TKP/TKC x140 only) Using this new defrost method is very easy: Targets Defrost too soon will squander energy by using too much heat-energy and defrosted too late will squander energy by decreasing the power factor of the refrigeration plant.

Evaporators can be de-iced already at temperatures from 2°C by forced air. When cooling stops, fans are turning on until ice and frost are melted.
PAGE 19
Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Page 19 Evaporator Fan Control For one or all of the 4 circuits it is possible to assign a relay for the evaporator fan. The fan control depends on the following parameters: • „cooling mode“ (mode page) The fan is controlled from the N/O-contact in refrigeration mode and from the N/C-contact in freezing mode. cooling mode= refrigeration refrig. relay fan relay refrig.
PAGE 20
Page 20 Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Roller Blind control Frame Heater control Selecting the „roller blind“ function on the assignment page activates the relay output for opening and closing the roller blind(s) automatically. A defrost overrides this function and opens the roller blind(s) for the defrost period.

Technical Manual Cold Storage Controllers TKP / TKC x130 - x140 Page 21 Adding controller units to extend cold storages If one controller unit has not enough ressources to control a cold storage, you can add one or more units. The necessary communication is made by the digital inputs. Each of the digital inputs can be assigned to the following jobs: Refrigeration Lock (avtive low): The refrigeration function of the controller unit will be stopped as long as 0Vare connected to the control input.

For this duty ELREHA has developed E-LINK, a transmission protocol, which will be transmitted on a two-wire bussystem based on the RS-485-Standard. With E-LINK, up to 78 controllers can be assembled. Each controller in a network has its individual adress („adress in netwk“, mode page).
