04 INSTALLATION AND CONNECTION
This unit should only be installed by a qualified technician. Inspect the motor bearings for proper operation prior to installation.
Do not install the fan on an unstable surface. First install the device on the application, than connect the protective earth!
The method of fixing stated is not to depend on the use of adhesives since they are not considered to be a reliable fixing means.
The fan is primarily constructed for installation with rotor on bottom or with shaft in horizontal. For other possibilities please contact for manufacturer's
support.
Ensure that the air-gap between the fan impeller and the stationary housing is constant. Distortion due to an uneven surface of basis may lead to a fan
failure. Air-gap between blade and cone-inlet (housing) should be of min. 3 mm.
Fan must be fixed to stationary housing 4x M8 at 90° on diameter 700mm as indicated on enclosed technical drawing. Use screws with property class
of 8.8. Secure all threaded joints with e.g. Loctite or by using self-locking screws.
The system manufacturer or the machine builder is responsible that the inherent installation and security information are harmonized with the valid
standards and guidelines (ex. EN 13857). To prevent dangerous situation and possible injuries the height and the diameter of inlet cone must be
appropriate dimensions.
Main electrical installation must be protected against short circuit with e.g. circuit breaker: max.16A, 400Vac, Type B and installation must be
constructed properly according to valid national directives.
Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
The fan is intended only to be connected to the fixed wiring or application’s circuit. An all-pole separating switch which must be incorporated to wiring
must disconnect also the fan.
This product can cause a d.c. current in the protective earthing conductor. Where a residual current-operated protective device (RCD) or monitoring
(RCM) device is used for protection in case of direct or indirect contact, only an RCD or RCM of Type B+ is allowed on the supply side of this product
and recommended sensitivity is 300mA with short time delayed intervention.
The electrical connection must correspond to the enclosed connection diagram.
Recommended cable for power supply and alarm-relay contact is an ordinary PVC cable acc. to IEC 60227-5 (eg. H05V2V2-F, 4G 1 mm²), no longer
than 2m, outer diameter 4.5 - 9.5mm. Power supply cable could include also additional leads for alarm circuit. Recommended cable for control circuit is
an ordinary PVC cable (eg. H05VV-F, 5X 0,5 mm²) , no longer than 2m, outer diameter 4.5 - 9.5mm and must be sufficient separated from the supply
circuit.
Ends of stranded wires needs to be provided with insulated ferrule (pin). Easier way to connect wires to the terminals if you use a screwdriver of
2.5x0.4mm dimensions to press the spring of terminal first and then insert the wire into the WAGO PUSH-WIRE® terminal. A screwdriver of 2.5x0.4mm
is necessary tool to remove conductor from the terminal.
Fan performed with terminal box is as supplied fitted with a sealing plug in the cable glands as a preventive against ingress of water or moisture inside
the terminal box. If the cable is not installed through the cable gland, sealing plug must remain in the gland!
Secure connection cable to the fan guard grill or to the motor holder with cable fasteners so that the water flows away from the cable and cable gland.
Try to maintain as much distance between supply and control cable as possible (recommended distance > 5cm).
Cable-end of the fan must be connected in a dry environment to prevent that water penetrate through cable into motor housing.
Where the fan is installed in shaft-horizontal position, the cable exit on the motor must be in down position.
Before putting into operation, check the resistance of protective-earth circuit of the entire application. Cross-sectional area and material of PE conductor
may be the same as cross-sectional of phase conductor or see guide regarding PE conductor : standard EN 61800-5-1.
A second protective earthing conductor must be installed to ensure requirements of standard "EN 61800-5-1 , 4.3.5.5.2 Touch current in case of failure
of protective earthing conductor ". For that purpose an additional M4 of 12mm depth hole or additional PE terminal is provided on motor housing and
marked with PE symbol. More information about dimensions of second PE conductor please find in guidelines of mentioned EN or equivalent standard
(a cross-section of second Cu conductor should never be less than 2.5mm
2
).

05 SPEED CONTROL
Rotation speed of a variable speed fan can be controlled by various signals:
- Linear voltage input (0-10V) or current input (4-20mA) or PWM input (PWM duty cycle 0-100%).
- MODBUS RTU protocol (Additional information are in documentation "Hidria EC Modbus parameters" and on www.modbus.org.
- Slave control output.
Linear voltage input is the most common and it is described below. The current input is also widely used, where long cables are necessary. PWM input
is used for electromagnetic noisy environments. PWM signal must be in square form with polarity the same as for linear voltage input (see connection
diagram). PWM duty cycle 0-100% correspond to 0-10V linear voltage input if the amplitude of the PWM voltage is Vp=10V. Amplitude of PWM signal
must not exceed 12Vp.
LINEAR VOLTAGE INPUT:
Linear input is factory adjusted to fit the customer’s sensor or other speed control reference. The input characteristic can be factory adjusted in terms of
increasing input sensitivity or attenuation.
For example: An air-cooled condenser is using a pressure sensor 0-20Bar => 0-10V, but the highest system pressure reached at maximum load is
16Bar => 8V. For optimal operation of the application the fan mounted on a condenser should run at max speed at 8V of input control voltage. In order
to achieve that, we need to adjust the input characteristic in a way the picture shows.

In order to prevent cycling from standby to run mode or run to standby
mode a small hysteresis is implemented. The default value is
approximately 200mV.
Hysteresis can be factory-adjusted in order to achieve customer
requirements.
Speed of a fan increases linearly with input voltage.
The fan operates in two different modes:
0-1.2 V…… Standby or stop mode
1.2-10 V….. Run mode
1.0-1.2V .....Hysteresis
Linear voltage input (0-10V DC) can be used as 0 (4)-20mA current
input with an additional resistor of 500 Ohms between GND and 0-10V
connection.

06 PUTTING INTO OPERATION
Before first start you should check:
a. Appropriate installation and electrical connection, especially resistance of the protective-earth (PE) circuit (max. 100mΩ).
b. If safety equipment is in place and motor protection device is in function.
c. If the impeller can rotate freely once the unit is mounted and the right direction of rotation is assured.
Only if all dangerous situations are excluded, the fan may be put into operation!
Switch ON the power supply.
Switch ON the device via the control signal and apply the speed setting voltage/signal and check the direction of the rotation and the smoothness of
running.
07 DIAGNOSTICS & TROUBLESHOOTING
Fan does not start or run - alarm rele status OPEN or FLASHES:
Possible causes: missing power (no line voltage), low voltage (under 320V), extremely thermally or mechanically overloaded or fan failure (short circuit
of electronic or windings).
Check line voltage, check value and polarity of control signal, check that rotor is free to rotate.
Fan does not start or run - alarm rele status CLOSE:
Possible causes: missing or inadequate control signal.
Check value and polarity of control signal.
Fan runs with half of desired speed - alarm rele status CLOSE:
Possible causes: Low supply voltage, inadequate control signal or fan overheating.
Check line voltage, check control signal, check temperature and sufficient airflow of cooling air or loss of motor cooling.
Attention !
In the event of fan failure is detected (short/open in circuit of electronics/windings), never try to repair the fan, but replace it with new one or return it to
the manufacturer for repair or replacement.
08 PROTECTIVE FEATURES
Short-circuit protection:
The motor and electronic has no protection functions against short circuit. Short-circuit protection must be provided with an external means - for
example with using a circuit breaker of max. 3x16A / 400V type B.
Locked-rotor protection:
As soon the rotor is blocked, the motor is switched off electronically. After de-blocking, the motor will restart automatically.
Mains under voltage:
If mains voltage falls below the nominal value the motor will keep running with degraded performance. Below 340V, the motor will be switched off
electronically in stand-by mode. When mains voltage returns to correct value, the motor will restart automatically.
In the specific case, the undervoltage protection may switch off the fan to stand-by mode, for example, fan running or testing at high pressure drop and
low voltage.
Over temperature protection:
Internally connected thermal overload protector to protect electronic and motor against over temperature.
