CHAPTER 2
GENERAL NOTES
2.0 Qualification of staff
Maintenance and installation work must be carried out only by an approved
electrician.
The QT150T should not to be used by children and persons with reduced physical,
mental or sensory capacities, without proper practical experience or expertise,
unless they are controlled or instructed on the product operation by the person(s)
responsible for their safety. Children should not play with the device. Cleaning and
maintenance must not be carried out by children without supervision.
2.1
Touch protection
The QT150T is supplied with a standard suction side protective grid. Depending on
the installation conditions protection against accidental contact on the discharge side
may also be required. Appropriate protective grids are available as an accessory.
According to the installation method (for instance installation in ventilation canals or
covered aggregates) fans are already protected and in such cases they do not need
a protective grid. It should be noted that the operator is responsible for compliance
with the current requirements and is liable for accidents.
2.2 Motor protection
The QT150B has an energy saving maintenance free EC Motor with high efficiency.
The motor is equipped with a thermal contact, wired in series, which automatically
switches on/off after cooling.
If the motor is blocked there will be an attempt to restart it every 3 seconds.
To start the motor a certain rotor position is required. If it doesn’t detect it, it outputs
pulses to the rotor in order to reach this position. This may take a few seconds.

FUNCTION
4.0
Function description
1. Switch-on delay
The fan turns on only after the set delay time (0, 45, 90, 120 sec.). By mutual
activation the light function can be switched on for a short time without fan coming on
stream. Turn on delay performs only after coming to a complete stop of the fan.
When switching between current stages – ignore applicable switch on delay. By
mutual activation of both stages, turn on delay can be considered only when time
function is activated on both stages.
2. Push button operation
If there is no switch on delay (DIP 1 / 2 off / off) activated, then switch inputs 1 or 2
can be controlled by a push button. For this relevant stage time function should be
activated.
The button must be pressed for more than 0.5 seconds. As soon as the stage will be
activated by the push button, the corresponding stage will switch off itself at the end
of the run on time.
3. Shut down
By switching off the current stage the fan will turn off only after the set lag time has
elapsed. The length of the run on time can be adjusted (6, 10, 15, 21 minutes).
When switching between the stages, the run on time will be ignored. By mutual shut
down of the both stages, the run on time will be considered only when time function
will be activated on both stages.
4. Intermittent operation
The fan can be set at adjustable intervals to perform automatically. The intervals can
be adjusted (0, 8, 12, 24 hours). During the interval mode adjusted post run time
corresponds to the duration of the cycle. Intermittent operation starts after the last
turn off. The required ventilation is the overriding importance for the intermittent
operation. In the interim required ventilation, started interval time will reset and
restart after the shutdown.
CHAPTER 5
CLEANING /
DISMANTLING
5.0 Cleaning
Safety instructions listed in Chapter 1.2 should be observed!
