Software-Varities

In consequence of further development of the hardware and the 

different mounting forms the listed types differ a little bit.
At present, controllers are delivered with a software version 7.xx 

(add. info on the label: Rev.P). Some of the described functions 

are not available or different in older versions. Controllers of the TKC series 

can only delivered with software version 2.35.

The differences:

•  Connection of a Remote Display: 

  Only from Vers. 4.03 resp. 6.00 and only at the rail types "TKP".

•  Error message "Hard" ,generated if the internal battery has low voltage:  

  Vers. 6.xx only.

•  Default value of the digital input 3 assigment is not "controller OFF",    

  but "- - -": From Vers. 6.02 only.

•  Intelligent Defrost: Only available with TKP/TKC x140 types.

•  Data storage and real time clock see technical data

 CONNECTION INFORMATION & SAFETY INSTRUCTIONS

Product warranty does not cover damage caused by failure 

to comply with these operating instructions! Nor will ELREHA 

be held liable for any personal injury or damage to property 

caused by improper handling or failure to observe the safety 

instructions and recommendations contained in this or any 

other ELREHA supplied document related to this product! 

This manual contains additional safety instructions throughout 

the functional description. Please pay close attention to these 

instructions!

TO AVOID RISK TO HEALTH OR POSSIBLE LOSS OF 

LIFE, DO NOT OPERATE IF: 

• The device has visible damage or doesn't work

• After a long storage period under unfavourable conditions

• The device is heavily soiled or wet

• When shipped under inadequate conditions
• Never use this product in equipment or systems that are  

  intended to be used in applications or under circumstances  

  that may affect human life. For applications requiring 

  extremely high reliability, please contact the manufacturer 

  before use.
• 

This product may only be used in the applications  

  described on page 1.
•  Electrical installation and placement into service  

  must be performed by qualified personnel only. 

• 

 To avoid the risk of Electrical Shock, all ‘PE’ terminals   

  must be connected to ground. Without adequately  

  grounding the unit, the internal noise filter will not work,  

  which can cause faulty readings, or inaccurate displayed  

  values to occur. 

• 

 Never operate the device without the supplied 

  enclosure. 
• To prevent electrical shock, the device may only be

  operated in a closed control cabinet or control box.
•  Be sure to observe all local, state, or federal safety  

  regulations in the location that the unit is installed.

•  Before installation, verify that the control specifications  

  suit the application details. Damage may occur if the unit  

  is operated outside of its specified limitations. 

  Examples:

  - Supply voltage (printed on the type label).

  - Environmental limits for temperature/humidity. 

  -  Maximum current rating for the relays. 

 

• Do not install sensor cables in parallel to high current  

  cables. Shielding must be connected to PE at the end  

  close to the controller. If not, inductive interferences may  

  occur. The wire gauge should be no less than 0,5mm².
•  Mounting the controller close to power relays is not

  recommended, due to the risk of strong electro-magnetic  

  interference, which can cause the unit to malfunction!
•  Ensure that the interface wiring meets all the necessary 

  requirements.
• All used temperature sensors must be identical. Never  

  use different types at the same time. This will not work.

Cleaning

 

The use of a dry, lint-free cloth is sufficient to clean the product. 

Never use liquids or acidic fluids!  Risk of damage!
