2.4.5 Accumulation of condensate
NOTE
Condensate flowing back into the switch cabinet can damage the electronic components
Internal temperatures below the dewpoint or damaged switch cabinet seals cause excessive accumulation of
condensate.
 Regular inspection of the seals assures protection against heavy condensate accumulation.
 Installation of a door contact switch reduces the accumulation of condensate when the switch cabinet is
open.
If the evaporator cools down, condensate can accumulate. In order to prevent damage to the switch cabinet and
the cooling units, the condensate is removed. The integrated condensate evaporator releases the condensate to
the environment. For safety reasons, there is a drain port with drain hose on the condensate evaporator.
 Accumulating condensate is collected by a condensate collecting bottle. It is available as an accessory.
 In case of questions about the cooling units or accessories and spare part orders, always specify the serial
number; see Spare part
2.4.6 Energy-saving mode
Cooling units with Multi-Controller (MC) are equipped with energy-saving mode. Therefore, it has a second TS2
temperature sensor (1), which is installed externally on the cooling unit. The TS2 temperature sensor (1) monitors
the switch cabinet interior temperature.
•
In the condition as supplied, energy-saving mode is activated when cooling operation is not activated for 30
minutes. The LCD then displays energy function "EN",
• If the switch cabinet interior temperature increases above the adjusted temperature setpoint during active
operation, a cooling command is sent and energy saving mode is interrupted.
• Cooling mode remains active until the temperature setpoint, minus hysteresis, has been reached. Energy-
saving mode always activates 30 minutes after the temperature setpoint is reached.
• If the temperature setpoint is undercut by the external TS2 temperature sensor (1) in energy-saving mode, the
evaporator fan (internal) switches off. The temperature setpoint is measured minus hysteresis.
• If the external TS2 temperature sensor (1) detects a temperature that exceeds the temperature setpoint, the
evaporator fan (internal) switches on. The value of the temperature setpoint is measured plus hysteresis.
• If no fault occurs, the fault indication output is closed in energy saving mode.
