INTRODUCTION

VRT200

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 230 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.

Before 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 VRT200 series can be supplied by 230Vac 50/60Hz .
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.

ELECTRICAL CONNECTIONS

VRT200

POWER SUPPLY

The VRT200 control unit must be supplied with 230Vac

10% 50/60Hz, 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

−

Over- and under-current LEDs ON + overtemp aux stop:

overtemperature alarm

−

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, over-current, overtemp-aux, 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 VRT200 control unit with these bars, we recommend the alarm threshold is programmed at 5%.

OPERATION WITH FANS NOT TECSYSTEM

The proper functioning of the VRT unit is guaranteed only for: fans with current absorption between 250mA
(IN MAX 20%) or 300mA (IN MAX 30%) and 5A , single phase, single speed and power variation is not
greater than ± 10%.

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.

for automatic calibration CAL LED

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

VRT200

The Product purchased is covered by the manufacturer's or seller's warranty at the terms and conditions set forth in
the "Tecsystem s.r.l's General Conditions of Sale", available at www.tecsystem.it and / or in the purchase agreement.
The warranty is considered valid only when the product is damaged by causes attributable to TECSYSTEM
srl, such as manufacturing or components defects.
The warranty is invalid if the Product proves to have been tampered with / modified, incorrectly connected,
because of voltages outside the limits, non-compliance with the assembly and use technical data, as described in
this instruction manual.
The warranty is always ex Corsico as stated in the "General Conditions of Sale".

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 or M2 over-current red LED ON

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

M1 or M2 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.
