5 Description IV Smart
5.1 Intended use of all IV Smart versions
• The fans are intended for installation in underground and above-ground parking structures, to facilitate ventilation
and cold smoke extraction.
• For optimum operation, the jet fan must be suspended horizontally from the ceiling in such a position that intake and
outlet are unobstructed.
• The fan is suitable for conveying clean air.
5.2 Incorrect use
Incorrect use refers mainly to using the fan in another way to that described. The following examples are incorrect
and hazardous:
• Conveying of explosive and combustible media
• Conveying of aggressive media
• Installation outside
• Operation in an explosive atmosphere

5.6 Information on the effects of CO on humans
Warning
This CO control unit is designed to protect people from the acute effects of carbon monoxide. It cannot
prevent the chronic effects of carbon monoxide exposure. The CO control unit can not fully protect people at
special risk, such as those with particular medical conditions. In cases of doubt, consult a doctor.
The table below sets out the symptoms, the corresponding CO concentrations and lengths of time that a person needs
to be exposed to this concentration until symptoms occur.

8.3.1 Fan speed specification
The minimum fan speed can be set via a potentiometer in the range from 20 % to 40 %. The potentiometer is only ac-
cessible once the housing cover has been removed. The fan speed increases proportionately to the CO concentration
until the maximum speed at 50 ppm. If a fault is detected, the fans operate at maximum speed in order to remove any
raised CO concentrations in the air. The following table provides information about the control unit's speed specifica-
tions to the fans.

8.4 Protecting the motor
Note:
In fans equipped with an EC motor, there is no additional motor protection needed. The motor protection is
integrated in the electronics of the motor.
Important
Damage to motor due to overcurrent, overload or short circiut.
♦Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault
occurs, the motor cannot switch on again automatically after it has cooled down.
♦Motor lines and temperature monitor lines should be laid separately on principle.
♦Without thermal protection: Use a motor protection switch!
9 Commissioning
Warranty claims can only be made if commissioning work is carried out correctly and written evidence thereof is
provided.
Safety information
♦Observe 2 Important safety information, page 1
Preconditions
♦Installation and electrical connection have been
correctly performed.
♦Before switching the fan on, check for externally
visible damage and ensure that the protective
equipment functions properly.
♦Inlet and outlet are free.
♦Cable glands are tight.
♦Safety devices have been fitted.

Tests
Do the tests requested in the commissioning report (15 Commissioning Report, page 15)
9.1 Tests when activated EC CO version
9.1.1 Function test
A function test is carried out once the voltage supply is connected, with the displays, the potential-free contact and the
fans being switched on briefly. The control unit has been installed correctly if the power display lights up permanently,
the CO alarm and fault display goes out after 2 seconds and the audible display does the same after 1 second. The po-
tential-free contact must tighten after 1 second and therefore establish a connection between X7.2 and X7.3. In addi-
tion, no faults must be displayed after around 15 seconds. In the Chapter 9.1.3 Visual and audible display, page 11 the
meaning of the different signal types are explained.
9.1.2 Warm-up time
Once the operating voltage has been connected, the control unit is in a warm-up state for around 6.5 minutes. During
this time, no CO measurements are carried out and no CO alarms are triggered. To ensure basic ventilation and to re-
move any raised CO concentrations in the air, the fans are controlled at a minimum speed. The warm-up time is needed
to give the CO sensor enough time for the CO measuring transducer's warm-up phase. Once the warm-up time has
elapsed, the control unit switches to its normal operating state (ready) and CO analysis takes place.
9.1.3 Visual and audible display
The table below distinguishes between the displays based on the control unit's four operating modes.

11.2 Alarm and fault handling Carbon monoxide control unit
The control unit continuously monitors the sensor's function, as well as the function of the fans. The following sub-
points describe the the meaning of the fault and CO-Alarm display and the way in which they should be responded to.
11.2.1 Thresholds for fault displays
The control unit distinguishes between two fault types, which are specified in more detail in the table below.

3. If the alarm triggers again after 24 hours, repeat
steps 1-2 and call the emergency gas services
(please check you have their number now) and if
necessary notify the relevant gas fitter.

11.3 Maintenance
Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is
provided.
We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are
specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning,
replacing defective components or other corrective measures. For traceability reasons, a maintenance plan must be
created which documents the work carried out. This must be created by the operator. If the operating conditions are
"extreme", the maintenance intervals must be reduced so that maintenance is carried out more frequently. Examples
of extreme operating conditions:
• Durable ambient temperature > 30 ºC or < -10 ºC, or temperature fluctuations > 20 K
