The SKOPE Factory pre-programmed Cold Key has the capability of instantly changing programme configurations. A Cold Key may also be used to introduce a customised program to meet a specific customer requirement.

  • Page 27: Diagnostics

    Diagnostics If the SKOPE electronic controller has a suspected fault, care must be taken to ensure accurate diagnosis. The controller has various programmable parameters that effect operation such as time delay and defrost modes. Any suspected failure must be double checked. Confirm all wiring and terminations are correct. Check that the probe resistance is correct and replace any faulty components.

  • Page 29: Replacing The Controller

    1. The electronic controller can NOT be interchanged with a standard Carel ir33 controller. 2. The electronic controller is universal and suitable for all SKOPE applications. Each controller is programmed for a specific product group making it non- interchangeable between product groups. The Carel ir33 controller is being gradually phased in to replace a variety of controllers including obsolete Dixell controllers.
