 Failure Messages / Failure Memory / Failure Codes

All failures will be stored with date and time of their appearance. To display this messages, 2 pages 

exist:

-  The "

Actual failures page

" contains all current failures in a short form. To make more than one  

  current failure visible, use the 'up/down'-keys. If a sensor is short or broken, this message also  

  appears on the actual value display.

-  The "

Historic failures

" page contains the last 

15

 failures with date and time of their appearance.

 Display of actual values and states

All actual values are shown on the '

actual values

page.

Display of the temperatures

' display their actual value in 

the range of -50 ... +100°C. At the same time, the 

display shows the functions which are assigned to 

the sensor.

 

Sensor  corrections  can  be  made  by  editing 

each  individual  sensor  reading.  The  resulting 

correction factors are listed on the mode page 

(

corr sensor 1-6

).

Setpoints:

The  active  day 

or night setpoints 

are  indicated  on 

the display by „->“ 

and „<-“.

Information about delay times

On the actual values page you will find all remaining 

delay times, so it is easy to verify the points in 

time when specific functions must start.

Status Displays

Temperature Sensors

There are two types of temperature sensors which 

can be used: 

-  

TF 201

, PTC sensor (2000 ohms@25°C), 

  !! not 3130/1 !!

-  

TF 501

, PT1000 sensor (1000 ohms@0°C)

  The type must be preset by '

sensor

' (mode 

  page).

'Standard Display' - Function

After switching on the controller, the display will 

indicate the 'Standard Display' after some seconds 

(in case of a failure it will display the actual failure). 

factory set is the actual value of probe 1.

This will also displayed if you have selected any 

parameter and you haven’t touch a button for more 

than 3 minutes. If you think that it is suggestive to 

show any sensor value as permanent parameter, 

do the following:
Change permanent parameter
-  Select the parameter you want to have as 

  'Standard Display'

-  Press "

" and "

 " simultaneaously.

  The display becomes dark for a moment, after  

  that the selected parameter will be shown as  

  the "standard display".

 Configuration Concept

The TKx controllers series has a ´

free configu-

rable concept

', that means all in/outputs have no 

fixed functions. All inputs and outputs (

6 relays, 6 

sensors, 4 digital (OC)-inputs, 1 analog output

) can 

be configured to work with any integrated control 

functions or all of the 4 control circuits.

Sensors

Each sensor is able to fulfill up to 3 functions at the 

same time (function sensor X a, function sensor X 

b, function sensor X c, X = sensor no.). 

e.g.:

1.  control sensor and alarm sensor simultaneous-

ly

2.  control sensor and defrost sensor simultaneous-

ly, e.g to control a    

 

chiller 

cabinet at the air outlet.  

Virtual Sensors

Up to 6 probes can be combined to a "virtual" sen-

sor, which allows an average determination with 

adjustable quantifying.

Digital Inputs (OptoCoupler Inputs)

Each digital input can be assigned to one of the 

possible functions.

Relay Outputs

Each relay can be used to control one of the possible 

functions. The same function can even be allocated 

to multiple relays.

Parameters

Parameters  of  functions  which  are  not  assigned 

will not appear in the parameter pages to improve 

survey.

Assignment

The function of each input and output can be preset 

on the 'assignment page'. The assignment can be 

done by the keys or via interface.

Example of a configuration for a freezer with 3 

evaporators:
