2) AUXILIARY POWER SUPPLY
The VRT200 has 2 power supply inputs: the first gives power supply only to the unit and it
has a small capacity (5VA max.), the second gives power supply to the fan motors, therefore it has to be connected with the appropriate power supply. The lack of the first power
supply input excludes every functioning both of the unit and of the fans, even if we have
voltage on the second input.
3) FUNCTIONING
When the unit turns on it makes a LAMP TEST and it goes in REMOTE mode. In this way
the fans are activated by the remote input contacts closure.
•
HOW TO START THE FANS BY THE PANEL
To start the motors in local mode push the button LOCAL/REMOTE in order to set up the
LOCAL mode (led LOCAL ON and led REMOTE OFF); push now the button “START/
STOP” in order to activate or disactivate the motors.
At the end of these phases in LOCAL mode, push again the button LOCAL/REMOTE in
order to make the unit works in normal conditions (REMOTE mode)
•
HOW TO START THE FANS BY REMOTE
Fans are activated when ENABLE input is driven by FAN contact (10-11) of the unit T154.
•
Push the button L.T. in order to make the LAMP TEST.
•
HOW TO MAKE A REGENERATION OF A MOTOR IN TRIP
To restart a turned off motor after an over/under current alarm, press RESET push button
after having carried out the due inspection and possible repairs.
•
HOW TO CHECK THE MOTORS

NOTE:
Led In on: correct working of the motor
Led >In on: motor alarm and stop for max. current
Led <In on: motor alarm and stop for min. current
The alarm conditions of a motor or the lack of auxiliary power supply in the meter
cause the closing of contacts 8-9 of ALARM/FAULT relay

NOTES
The led showing the highest admitted absorbed current variation (±%) is flashing.

Choice of the
data item to be
programmed
Load the highest admitted current variation
as percentage value (5%, 10%) with respect
to the rated value In.

Confirmation of
chosen
data item

Motors start for
automatic
calibration
To execute the automatic calibration, all the
motors have to be connected with
a definitive configuration.
START: motors are ON for 90 seconds,
CAL led is fixed while STATUS section leds
are flashing.
When the calibration is over, the
motors turn off and CAL led
is flashing again.

6) WARRANTY
The series “VRT” units are under warranty for 12 months from the delivery date signed on
the unit.
The warranty is recognised when the unit breaks down due to some causes chargeable to
TECSYSTEM srl such as production faults or insufficient calibration.
The warranty is not valid if the unit has been tampered or when it has been damaged by a
wrong voltage supply beyond the highest working limits (220Vac). The warranty is not valid
if the unit should be burnt out by too high transient voltage peaks. In this case TECSYSTEM srl is not answerable for damages caused by faulted or defective units. All the delivery
expenses (there and back) of the unit must be paid by the Customer.
In case of dispute, the qualified FORUM is the one of Milan.
Warranty is always EXW our company in Corsico (incomterms 2000).

7) FAN MOTOR CONNECTION
Motors must be DIRECTLY connected to VRT200, since it gives PHASE and NEUTRAL to
each motor.
