FUNCTION SEQUENCE AND LED FUNCTION DISPLAY

Three function display LED’s are provided to give a visualisation of the function sequence during start-
up of the cooler. The top LED (red) indicates that the temperature set by the ECP automatic control
electronics has been exceeded or has not been reached. The central green LED shows that the cooler
is operating. The bottom red function display LED gives an alarm if the temperature falls too low.




Switching the cooler on

As soon as there is a mains voltage, the top red LED lights up. This
indicates that the temperature of the cooler is above +8°C.





Normal operation

After around 20 minutes the cooler has been cooled down to a
temperature below +8°C. The top red LED goes out.

The status collector alarm contacts are deactivated and control the
automatic external release for gas measurement.

The central green LED is alternately switched on and off by the ECP
automatic control electronics in a load-dependent cycle. The cooler is
ready to use.

CLOSING DOWN

N O T E !

The area in which the cooler is situated when not in use must be
kept free of frost at all times!



If the cooler unit is putting out of action for a short time no particular measures need to be taken.

We recommended sweeping the cooler with inert gas or ambient air while the unit is putting out of
action for a longer time. Condensate has to be removed completely from the cooler.

W A R N I N G !




Aggressive condensate is possible.
Wear protective glasses and proper protective clothing!
