Trouble-shooting

Unfortunately, error messages on the system cannot be completely ruled out. However, most errors can be rectified with a few simple steps. In order to interpret the error message correctly, we have created an overview of possible error descriptions, their causes and solutions for troubleshooting.

	Error description	Cause	Troubleshooting
1	System does not start, no display on the front foil	Power cord not plugged in	Plug in power cable
		Fuses not inserted or defective	Check fuses and replace if necessary
		No voltage on the socket used	Check fuses
		Power switch to Off position	Switch on power switch
		Incorrect mains voltage	Check mains voltage
		Three-phase network without neutral	Check mains connection
2	Plant does not start, warning signal audible, turbine fault lights up	Turbine failure / malfunction	Switch off the system and contact the manufacturer or national representative.
	Filter saturation indicator lights (green + yellow + red)	Filter completely saturated	With the aid of the filter status display (depending on the system type), decide which filter must be changed and reorder replacement filters
	Fault temperature lights	Temperature problem	Switch off the system and allow it to cool down. Check ambient temperature and suction hose (clogged, length/cross-section), restart system, if the error occurs again, contact manufacturer or national representative.
3	System does not start, Run/ Standby button flashes	Plant is in standby	Press the Run/Standby button
3	System does not start, Run/ Standby button flashes	Interface incorrectly wired Attention! Interface partly only optionally available!	Check interface Pin 7 = + Pin 8 = - If there is a bridge between pin 9 and pin 10, the remote control is dominant, switch the system to Run via remote control.
4	System running, yellow warning flashes, Filter saturation indicator lights up (green + yellow).	Filter partially saturated (depending on the type of plant, the affected filter is also displayed in yellow).	Green area - filter saturation O.K. Yellow area - reorder replacement filter Red area - filter fully saturated - replace
5	Speed cannot be changed on the system	Remote control connected, Speed control from external (Pin 14,15) Attention Interface partly only optionally available!	Speed control from external is dominant before the speed set manually on the device.
6	Speed can be adjusted via the Interface not change	Speed adjustment on the unit dominant Attention Interface partly only optionally available!	Speed control from external is dominant before the speed set manually on the device.
7	No / little suction power, Filter saturation indicator shows no Filter change	Intake line clogged, defective, kinked or not plugged on	Clean or replace the suction line
		Suction power not set correctly	Increase the suction power at the speed controller (front) or remote control.
		Motor / control defective	Contact country representative
8	System runs unsteadily or vibrates strongly	Engine mount defective	Replace motor or contact national representative
8	System runs unsteadily or vibrates strongly	Impurities on the impeller of the motor	Check the filter for leaks, if necessary contact the national representative.
