Troubleshooting and error rectification
Cause
Power cable is not connected
Fuse is not installed or defective
Used electric socket doesn't provide any voltage
Power switch in off position
Incorrect mains supply voltage
Three-phase network without neutral conductor
Turbine malfunction / failure
Filter fully saturated
Temperature problem
System is in standby mode
Incorrect wiring of the interface
Attention: In part the interface is only available as an
option!
Filter partially saturated (depending on the type of system,
the filter affected is displayed in yellow)
Remote control collected, external speed control (pins
14+15)
Attention: In part the interface is only available as an
option!
System speed control is dominant
Attention: In part the interface is only available as an
option!
Clogged, defective, kinked or unconnected intake piping
Incorrectly set extraction performance
Defective motor / control system
Defective motor bearing
Remove impurities from the motor fan wheel

Remedy
Connect power cable
Check the fuses and replace them if required (Figure 2 Item 8)
Check the circuit breakers
Turn on the power switch
Check supply voltage
Check the connection to mains power supply
Turn off the system and contact the manufacturer or your regional
TBH sales team
Decide by means of the filter status indicator (depending on the
type of system), which filter needs to be replaced and order a
replacement filter.
Shut down the system and let it cool down. Check ambient
temperature and extraction hose (clogged, length/profile), restart
the system. In case the error remains unsolved, please contact the
manufacturer or your regional TBH sales team
Push the run/standby button
Check interface
Pin 7 = +
Pin 8 = -
In case there is a jumper between the pins 9 and 10, the remote
control is dominant; use remote control to switch the system into
run mode
Green – filter saturation is O.K.
Yellow – order replacement filters
Red – filter fully saturated; replace it
External speed control is dominant and has priority over manual
adjustment of the rotational speed
External speed control is dominant and has priority over manual
adjustment of the rotational speed
Clean or replace intake piping
Increase extraction performance using the speed controller (front)
or the remote control
Contact your regional TBH sales team
Replace motor or contact regional TBH sales team
Check filter for leakiness and contact your regional TBH sales team
if necessary
