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. 23: Function of the electronic controller
The Standard-Controller (SC) has an indicator unit with a green LED light (1). Different switch cabinet temperature setpoints and
upper limit temperatures 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 and upper limit temperatures are set by the DIP-switch (5), see
chapter "Setting the DIP-switch", Page 40.
• 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 match the specified technical data, see chapter
"Technical data", Page 24.
