The limp home aspect of this alarm ensures that the cooler continues to operate with limited disruption to
the end user. The refrigeration system will operate - cooling the products - while a service engineer visit is
scheduled.
The table below describes how the ems100 Nexo controls the cooler during this time and what the end
user will see:
Audio alarm Display
Audible alarm sounds for ten seconds every compressor cycle
(compressor switches ON or OFF) - if the buzzer is enabled.
In Ready mode
In Saving mode
While the controller displays the above, the controller is managing the compressor and the fans:
` The compressor cycles fteen (15) minutes o, then ve (5) minutes on.
` The fan switches on with the compressor on cycle, then cycles when the compressor is in the
o cycle as set by the FCO (fan cycle on) and FCF (fan cycle o) parameters.
The fault clears and normal operation resumes when one of the following occurs:
` The appliance sensor temperature reaches SP (set point)
` The power is cycled to the controller - restarting the Ct (refrigeration system failure) timer
once the compressor switches on.
` The Down button is pressed.
