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 (4), various switch cabinet temperature setpoints and upper limit temperatures can be adjusted. If an
error occurs, the green LED light (1) blinks.
•
If assembly and installation work are completed, switch on the power supply to the cooling unit.
•
The cooling unit 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.
Exception: Energy-saving mode and antifreeze option.
•
The cooling unit (2) is equipped with an electronic control unit. A temperature sensor (5) 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 (4); see DIP switch.
•
If the upper or lower limit temperature is exceeded or undercut, a fault indication is triggered (6).
•
The green LED light (1) 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 ECoolPLANT software 2.X is available for download free of charge on the website:
https://www.pfannenberg.com/.
 The corresponding operating manual for the ECoolPLANT software is available HERE and from My
Pfannenberg.
 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
