Click on below YouTube links for procedures: 


Intermittent communication issues will be experienced if low voltage data/communication cables do not have adequate spacing between them. See below Technical Bulletin A01/16 Data/Comms and 240 Volt cable routing 



To prevent intermittent communication issues with Multiple cooler installations 

  • Ensure communication cables are installed in series as per the below
  • Ensure dip switch on last cooler is set to the "ON" position as per the below

Note! To accurately diagnose faults on Seeley products, we recommend that Service Technicians use a wall controller on a short test lead at the cooler. This way the functions of the cooler, as well as the diagnostics LED's can be immediately observed in relation to the commands issued by the controller.

Communication cable description - PVC sheathed 6 core 7/0.16mm (26awg) copper wires - low resistance

Termination plug end - Plug 6 pin Farnell 781-289


When dealing with communication issues Technicians should have an RJ connector Crimp tool as well as the RJ12 6P6C connectors.

 

Make sure the crimping tool is capable of terminating the two different types of cables used on Seeley products.
