CONTROL CABLE

Control cable should be shielded. Keep control cable distance

min 200 mm from mains and motor cable.

CONTROL SIGNALS

Fan is started with potential free switch connected between

terminals 12 and 18. The circuit voltage is 24 VDC. AUTO-mode

should be selected from operation panel.

Speed reference can be given from with 0…10 V signal

connected in terminals 53(+) and 55(-). Alarm signal is availa-

ble in relay1 (terminals 01, 02 and 03).

Running indication is available in relay 2 (terminals 04,

05 and 06).

Single speed operation:

Set constant speed reference (rpm) in parameter 411.

Only external start signal is needed.

Two speed operation:

Lower speed reference (rpm) is set in parameter 411 and

higher speed reference (rpm) in parameter 319. Lower speed

is activated with start signal (terminals 12-18). Higher speed is

activated by closing terminals 12-29. Speed controller can be

controlled via Modbus RTU. RS-485 cable is connected to the

terminals 68 (P), 69 (N) and 61 (COM). If speed controller is last

unit in line, it should be terminated by setting switch S801 in

ON position. Modbus operation is described in speed controller

operation instructions.

START UP AND FUNCTIONAL TESTING

After power up test check motor rotation:

Set speed controller to Hand on mode from operation panel.

Motor will start to the minimum or speed set in operation panel.

To change the direction of rotation:

• Remove power to the speed controller and wait for power to

discharge.

• Reverse the connection of any two of the three motor cables

on the motor or frequency converter side of the connection.

When direction of rotation is right set speed controller to Auto

on mode. Then speed controller will follow control signals.

PARAMETERS

Speed controller parameters are set at the factory providing

for optimal performance of fan and motor. This includes motor

parameters, ramp times, starting and stopping methods and

speed limitations. Changing of these parameters may result

in unstable operation or motor won’t start. Original parameter

values can be downloaded from operation panel in case of

losing them.

SUPPLY CABLE

Mount mains supply to terminals L1, L2 and L3 and ground

wires to earth terminal and tighten.

Short circuit protection:

The speed controller must be protected against shortcircuit to

avoid electrical or fire hazard. The fuses mentioned below are

recommended to use to protect service personnel and equip-

ment in case of an internal failure in the speed controller. Speed

controller provides full short circuit protection in case of a short

circuit on the motor output.

Over current protection:

Provide overload protection to avoid fire hazard due to over-

heating of the cables in the installation. The speed controller

is equipped with an internal over-current protection that can

be used for upstream overload protection (UL-applications

excluded). See par. 4-18

Current Limit. Moreover, fuses or circuit breakers can be used

to provide the over-current protection in the installation. Over-

current protection must always be carried out according to

national regulations.

Leakage Current (>3,5mA)

EN/IEC61800-5-1 (Power Drive System Product Standard)

requires special care if the leakage current exceeds 3,5 mA.

Earth grounding must be reinforced in one of the following

ways:

• Earth ground wire of at least 10 mm2

• Two separate earth ground wires both complying with the

dimensioning rules

Isolation switch

All speed controllers may be used with an isolated input sour-

ce as well as with ground reference power lines.

RECOMMENDED PRE-FUSES

MOTOR CABLE

Motor and speed controller is delivered with 3,5 m long motor

cable. If it should be replaced with longer one or disconnected

at the other end.

Following rules should be meet and considered:

• Motor cable should be shielded type.

• Shield should be grounded 360° at both ends of cable.

• Motor cable should be no longer than 20 meters.

• Motor is connected to star inside the motor.

ALARMS AND WARNINGS

If alarm or warning messages appear, consult speed controller

operating manual in place fault messages and troubleshooting.

Protection and Features:

• Electronic thermal motor protection against overload.

• Temperature monitoring of the heatsink ensures that the

speed controller trips if the temperature reaches 95 °C ± 5 °C.

An overload temperature cannot be reset until the tempera-

ture of the heatsink is below 70 °C ± 5 °C. The speed controller

has an auto derating function to avoid it's heatsink reaching

95 °C.

• The speed controller is protected against short-circuits on

motor terminals U, V, W.

• If a mains phase is missing, the speed controller trips or

issues a warning (depending on the load).

• Monitoring of the intermediate circuit voltage ensures that

the speed controller trips if the intermediate circuit voltage is

too low or too high.

• The speed controller is protected against earth faults on

motor terminals U, V, W.

MAINTENANCE

Inspect the motor regularly and keep it clean. Especially impor-

tant is to keep the ventilation inlets clean.

If the motor protection is activated: The cause of the mal-

function must be investigated and corrected before starting the

motor again; motor failure, temporary overload or wrong set

values in the protection device.

BEARINGS

Most fans and motors are equipped with permanently lubricated

bearings. As a guideline the expected lifetimes is 40 000 h.

Type of bearing is to be found on the marking on the motor.

If there is a need for changing bearings contact Fläkt Woods

for instructions.values in the protection device.

FREQUENCY CONVERTER

BEARINGS

1. The frequency converter must be disconnected from mains

if repair work is to be carried out.

Check that the mains supply has been disconnected and

that the necessary time has passed before removing motor

and mains plugs.

2. The [STOP/RESET] key on the LCP of the frequency converter

does not disconnect the equipment from mains and is thus

not to be used as a safety switch.

3. Correct protective earthing of the equipment must be estab-

lished, the user must be protected against supply voltage and

the motor must be protected against overload in accordance

with applicable national and local regulations.

4. The earth leakage currents are higher than 3.5 mA.

5. Protection against motor overload is set by 1-90 Motor

Thermal Protection. If this function is desired, set 1-90 Motor

Thermal Protection to data value [ETR trip] (default value) or

data value [ETR warning].

Note: The function is initialized at 1.16 x rated motor current

and rated motor frequency.

For the North American market: The ETR functions provide

class 20 motor overload protection in accordance with NEC.

6. Do not remove the plugs for the motor and mains supply

while the frequency converter is connected to mains. Check

that the mains supply has been disconnected and that the

necessary time has passed before removing motor and

mains plugs.

7. Please note that the frequency converter has more voltage

inputs than L1, L2 and L3, when load sharing (linking of DC

intermediate circuit) and external 24 V DC have been installed.

Check that all voltage inputs have been disconnected and

that the necessary time has passed before commencing

repair work.

Warning!

Speed controller tries to restart the motor after

alarm so the fan may start automatically.

Warning!

The voltage of the frequency converter is

dangerous whenever connected to mains.

Incorrect installation of the motor, frequency

converter or fieldbus may cause death,

serious personal injury or damage to the

equipment.

Consequently, the instructions in this manual,

as well as national and local rules and safety

regulations, must be complied with.

start. Consequently, the stop key [STOP/RESET] must

always be activated; following which data can be modi-

fied.

3. A motor that has been stopped may start if faults occur

in the electronics of the frequency converter, or if a

temporary overload or a fault in the supply mains or

the motor connection ceases.

Warning!

Touching the electrical parts may be fatal

- even after the equipment has been discon-

nected from mains.

Also make sure that other voltage inputs have been discon-

nected, such as external 24 V DC, load sharing (linkage of

DC intermediate circuit), as well as the motor connection

for kinetic back up. Refer to the Operating Instructions for

further safety guidelines.

Warning!

The frequency converter DC link capacitors

remain charged after power has been discon-

nected. To avoid an electrical shock hazard, disconnect

the frequency converter from the mains before carrying

out maintenance. Wait at least as follows before doing

service on the frequency converter:
