The section consists of a rotary heat exchanger and driving mechanism. The casing has got an inspection panel en-
abling access to the rotor's driving mechanism.
The hygroscopic heat exchangers may have got a tray installed under the exchanger, located within the AHU frame
free space, with a connector leading to the operational side of the AHU.
The driving mechanism consists of a belt transmission, electric motor and motor base with self-adjusting belt tension-
ing function.
The electric motor is delivered with a 0,37kW; 1×230V/3×230V; 50Hz inverter.
The internal AHUs are equipped with Danfoss FC51 inverters and external AHUs are equipped with LG IC5 inverters.
Below you can find inverter settings for the 0÷10V signal control from an external source for both inverter types.
Wiring of inverters according to their respective OMMs.
If the AHU has been delivered together with the Klimor control system, do not use these settings. Please use infor-
mation provided in corresponding control system OMMs.

*/ Once this parameter is set to function [2] the PRESS HAND START message appear in the display. When the HAND START button on the control
panel is pressed, the converter proceeds with the auto matching.
When the auto matching is complete, press OK on the control panel and the parameter is automatically set to [0] value. Now you can proceed with the
programming.
