ATTENTION
Damage to the unit
Operation without the unit cover prevents sufficient air supply to the condenser and restricts the intended cooling function.
• Only operate the cooling unit with the unit cover in place.
Fig. 18: Electronic control function
The Standard-Controller (SC) has an indicator unit with a green LED light (1). Different switch cabinet temperature setpoints as
well as upper temperature limits can be set with the DIP-switch (5). The green LED light (1) flashes when an error occurs.
• Switch on the power supply to the cooling unit after completing the assembly and installation work.
• The cooling unit (2) starts operation and the LED light (1) of the indicator unit switches to green continuous light. The
units run continuously after applying the supply voltage and closing the door.
• The cooling unit (2) is equipped with an electronic controller. A temperature sensor (4) measures the temperature of the
sucked in interior switch cabinet air (3).
• The different switch cabinet temperature setpoints are determined by the DIP-switch (5), see section "Setting the DIP-
switch", Page 34.
• Exceeding or dropping below the lower and upper temperature limit leads to tripping of the fault indication (6).
• The green LED light flashes when there is a fault indication.
• In the Standard-Controller (SC) system messages or error information can only be read out by the USB adapter,
configuration software
NOTE
• The ambient conditions and switch cabinet interior temperatures must correspond to the prescribed technical data,
see section "Technical data", Page 20.
