  • Page 11 This value can be increased if necessary. The capacity can similarly be limited so that the compressor cannot deliver 100% capacity. It is not normally necessary to limit this max. capacity. Refrigeration No refrigeration AK-PC 560 Manual RS8GE202 © Danfoss 01-2016...
  • Page 12 If the entire condenser capacity is to be controlled by a frequency converter, AK-PC 560 must send an analog signal about the required capacity (“c29” = 9). The signal varies from 0 to 10 V. Signal and capacity have the following context.

    To ensure that the fans are ‘exercised’ a test will be carried out every 24 hours to check whether all relays have been in operation. The relays that have not been used will now be activated for 30 seconds, but with a pause of one hour between individual relays. Manual RS8GE202 © Danfoss 01-2016 AK-PC 560...
