INTRODUCTION

VRT600 SERIES

ATTENTION:

Read the manual carefully before starting to use the control unit. Keep the instructions for future reference.

Do not open the device, touching any internal components can cause electric shock. Contact with 110-240 Volts
AC can be fatal. To reduce the risk of electric shock, do not dismantle the back of the device for any reason. Moreover its
opening would void the warranty. B

efore connecting the device to the power supply, make sure that all the

connections are correct.

Always disconnect the unit from the supply before any cabling modification.

Any intervention on the equipment must be entrusted to a qualified repair engineer

Failure to comply with these instructions can cause damages, fires or electric shock, and possible serious injuries!

POWER SUPPLY

The VRT600 series can be supplied by 230Vac 50/60Hz o a 12Vac –Vcc, depending on the model purchased.
Before using it, make sure the power cable is not damaged, kinked or pinched. Do not tamper with the power cable. Never
disconnect the unit by pulling the cable, avoid touching the pins. Do not carry out any connecting/disconnecting with wet
hands. To disconnect the device, do not use objects such as levers. Immediately disconnect the device if you smell burning
or see any smoke: contact technical service.

LIQUIDS

Do not expose the equipment to splashes or drops, do not position it in places with humidity exceeding 90% and never touch
with wet or humid hands during storms. If any liquid penetrates the control unit, disconnect it immediately and contact
technical service.

CLEANING

Disconnect the power cable before cleaning the control unit, use a dry cloth to dust it, without any solvent or detergents, and
compressed air.

OBJECTS

Never insert any objects into the cracks of the control unit. If this happens, disconnect the control unit and
contact an engineer.

USE RESERVED TO QUALIFIED PERSONNEL

The purchased goods are a sophisticated electronic device that is totally unsuitable to be used by non-qualified personnel.
Any intervention must be carried out by a specialist engineer.

ACCESSORIES

The use of non-original accessories or spare parts might damage the unit and endanger users' safety. In the event of faults,
contact technical service.

LOCATION

Install the control unit indoors, in a place protected from water splashes and sun rays. Do not place near heat sources
exceeding the parameters stated in this manual. Position on a stable surface, far from any possible vibrations. Position the
unit as far as possible from any intense magnetic fields.

REPAIRS

Do not open the control unit. For any fault, always use qualified personnel. The opening of the control unit and/or the removal
of the series identifying label entails the automatic forfeiture of the warranty. The Warranty seal is applied to all devices, any
attempt to open the unit would break the seal and cause the consequent automatic forfeiture of the warranty.

POWER SUPPLY

The VRT600 control unit must be supplied with 230Vac

10% 50/60Hz. The VRT600 - U

control unit must be supplied with 12 Vac - Vdc 50/60Hz.

According to the model purchased, check the connection diagrams on pages 9 and 10.

A variation in the network voltage of over 10% might cause alarms because of the current variation in the load.

If the electrical system is affected by harmonic frequencies, alarm warnings might be triggered because of the
consequent variation in the current absorbed by the motors.

It is good practice to make sure that the level of system harmonics is not such as to cause malfunction or damages to
all the connected electrical and electronic instruments, in compliance with the regulations in force for the type of
system.

OPERATION

When switched on, the device carries out a LAMP TEST and is set either in REMOTE or LOCAL mode, according to
how it was set before being switched off.

In REMOTE mode the fans are activated when contact 52-53 closes, which must be connected to the FAN contact of
the temperature control unit.

In LOCAL mode the fans are activated by pressing the <START-STOP> button. The status of operation is stored in
case of power failure.

HOW TO CHECK THE ALARM STATUS

−

Running LED OFF:

no ventilation activation control

−

Running LED ON:

REMOTE or LOCAL ventilation activation

−

Over- and under-current LEDs OFF:

motor operating correctly

−

Over-current LED ON:

motor stopped due to over-current

−

Under-current LED ON:

motor working + under-current alarm signal

−

Under-current LED flashing:

motor disconnected while auto-tuning

−

Over-current LED ON:

motor consumption >5.5A (immediate trip without any delay)

−

All LEDs flashing:

corrupted memory error (ech); press reset and repeat the programming procedure

N.B.:

A motor in a state of alarm or the interruption of supply to the device make contacts 8-9 of the FAULT relay close.

HOW TO RESET A MOTOR IN ALARM

To reset an alarm due to under-current or over-current, press the RESET button after carrying out the necessary
checks and any repairs might be required.

OPERATION WITH BAR 400 OR 600

The 400 and 600 bars are fitted with low current variation motors in case of a motor block.

To optimise the operation

of the VRT600 control unit with these bars, we recommend the alarm threshold is programmed at 5%.

IMPORTANT NOTE: if an existing control unit must be replaced with a new one, to guarantee its
correct and safe operation, all the connecting terminals must be replaced with the new terminals supplied, on
condition the brand of the new terminals is different from the one of the previously installed ones.

To perform the "automatic calibration" all motors

must be connected as per final configuration.

At the START the motors are

switched ON for 60 seconds, the

CAL LED flashes and LEDs 0-5-10-

20-30 light up in sequence.

When the calibration is completed, the

control unit resets and goes

into REMOTE mode

N.B.: any connection or programming errors might cause fan malfunctions.

ATTENTION:

We recommend you check the control unit before starting the device.

The default parameters set by TECSYSTEM might not suit your requirements.

Programming the device is the end user’s responsibility: the set alarm thresholds and the enabled functions
described in this manual must be checked (by a specialized technician) referring them to the application and
system characteristics on which the control unit is installed.

PROGRAMMING

TROUBLESHOOTING

CAUSES AND SOLUTIONS

The control unit does not switch on and the supply to
terminals 40-42 is correct.

Check that: the connector is correctly inserted into its housing,
the wires are tightened, there is no evidence of burning on the
connectors. Disconnect the power supply, carry out the above
and reconnect.

M1-M2-M3-M4-M5-M6 over-current red LED ON

Check the condition of the fans and replace any faulty ones. Re-
program the device.

M1-M2-M3-M4-M5-M6 under-current yellow LED ON

Check the condition of the fans, the cables and the supply.
Re-program the device.

All the LEDs are flashing

Memory error, press RESET and repeat the programming
procedure.

All the LEDs are ON

Likely microcontroller fault, return the device to Tecsystem for
repair.

Contact

TECSYSTEM Technical Department if the problem persists.
