3.0 Motor protection 2 has
triggered!
Frequency converter of the extract-air fan notifies a malfunc-
tion.
➯ Check the frequency converter and the thermal contact
or resistor of the motor.
3.1 Motor protection 1 has
triggered!
The frequency converter of the supply-air fan has notified a
fault.
➯ check the frequency converter and the thermal contact
or resistor of the motor.
3.2 Analog input 1 No input signal at the sensor input of the supply-air fan.
➯
Check the 2-10V signal of the sensor, ensure that no 0-10V
sensor is connected.
3.3 Analog input 2 There is no input signal at the sensor input of the extract-air fan.
Ü Check the signal of the 2-10V sensor and ensure that no 0-
10V sensor is connected.
3.6 Setpoint Volume flow 1 A valid setpoint for the supply-air volume flow is not available.
➯ Specify setpoint.
3.7 Setpoint Volume flow 2 No valid setpoint for the extract-air volume flow available.
➯
Specify setpoint.
3.8 Sensor volume flow 1 A valid actual value for the supply-air volume flow is not
available.
➯ Check sensor signal and range.
3.9 Sensor volume flow 2 A valid actual value for the extract air-volume flow is not
available.
➯ Check sensor signal and range.
3.10 Pressure setpoint 1 A valid setpoint for the supply air pressure is not available.
➯
Specify setpoint.
3.11 Pressure setpoint 2 A valid setpoint for the extract-air pressure is not available.
➯
Specify setpoint.
3.12 Pressure value 1 A valid actual value for the supply-air pressure is not available.
➯ Check sensor signal and range.
3.13 Pressure value 2 A valid actual value for the extract-air pressure is not available.
➯ Check sensor signal and range.
3.14 MATRIX.EXT Energy
recovery missing
The circuit board MATRIX.EXT for the control of the energy
recovery cannot be addressed.
Ü Check voltage supply, bus address, and function selector
switch.
3.15 MATRIX.EXT-FU mis-
sing
The circuit board MATRIX.EXT for the control of the frequency
inverter cannot be addressed.
Ü Check voltage supply, bus address, and function selector
switch.
3.16 Adiabatic cooling A controller reports that the measured value of the ERS inlet
temperature is missing or the Al 5 inlet is deactivated.
3.17 Adiabatic cooling A controller reports a communication failure between controller
and extender-module with adiabatic cooling function
(humidifier)
3.18 Adiabatic cooling A controller reports that the measured value of the ERS inlet
humidity is missing or the Al 6 inlet is deactivated.
