Corrective measures
 Select higher switch
cabinet-
Select temperature
setpoint.
 Inspect the switch
cabinet for leaks.
 Move components near
the air intake and outlet
further away in order to
prevent an air short
circuit. (The cold air is
diverted directly to the air
inlet by components.)
 Check the settings of the
cooling unit.
 Clean the heat
exchanger fins
(internal/external).
 Evaporator fan
check (internally) for
function.
 Check the refrigeration
circuit for escaping
refrigerant or leaks.
 If necessary, install a
cooling unit with a higher
cooling capacity.
 Replace Sensor 3 or the
controller circuit board
according to the unit
type.
