• Two connections are provided for connection of the collective fault signal. They are marked with the item
designation SK; see
• The fault signaling contact is potential-free.
 Ensure that the contact is loaded with a maximum of 230V, 1 A.
4 Operation
4.1 General functions
NOTE
Danger of damage to the cooling unit
Operation without the unit cover prevents the adequate supply of air to the condenser and limits the intended
heating function.
➢ Only operate the cooling unit with the unit cover installed.
The standard controller (SC) has a display unit with a green LED light (1). With the
DIP switch (5), various switch cabinet temperature setpoints and upper limit temperatures can be adjusted. If an
error occurs, the green LED light (1) blinks.
•
Once assembly and installation work is completed, switch on the power supply to the cooling unit.
•
The cooling unit (2) starts its operation and the LED light (1) of the display unit illuminates green continuously.
• After the supply voltage has been connected and the door is closed, the units run continuously.
• The cooling unit (2) is equipped with an electronic control unit. A temperature sensor (4) detects the
temperature of the air sucked in from the interior of the switch cabinet (3).
• The various switch cabinet temperature setpoints and upper limit temperatures are specified with the
• DIP switch (5); see table
• If the upper or lower limit temperature is exceeded or undercut, a fault indication is triggered (6).
• The green LED light blinks for a fault indication.
• With the standard controller (SC), the readout of system messages or error information is only possible via the
USB adapter, ECoolPLANT 2.X configuration software, with USB driver software.
 The ambient conditions and switch cabinet interior temperatures must correspond to the prescribed technical
data; see Technical data.
 The ambient temperature must be less than 55°C; see
