2. Intruduction
1. The MCRP 054 weather monitoring unit is used to control the
operation of actuators in the MCR-PROLIGHT and MCR P
vents or in ventilation windows which should be closed in wind or rain.
2. To the weather monitoring unit smoke exhaust control units,
ventilation control units or electromechanical actuators powered by
230 V or 24 V voltage.
3. The closing signal is generated on the basis of readings from a WM1
wind sensor and the RS1/RS2 rain sensor.
4. Output: the device has four switches which are activated in the event
of wind/rain or when mains voltage is lost. The switch remains
activated for a pre-set time after the rain/wind has ceased.
5. The value of rain intensity which activates the alarm can be adjusted
by the user (drizzle – heavy rain).
6. The value of wind force which activates the alarm can be adjusted by
the user - from a gentle breeze (about 5 m/s) to a gale (about 15 m/s).
7. Additional input for a vent position sensor (the circuit is closed when
the vents are open) makes it possible to optically control the vent
status.
8. The device is equipped with the optical signals to indicate the
following status:
•
230V~ power supply green LED
•
“Wind” alarm red LED
•
“Rain” alarm red LED
•
“Vent open” signal amber LED
9. The device is equipped with the wind speed indicator – a line indicator
consisting of 7 amber LEDs and one red LED (for wind speeds over
15 m/s).
10. Wall-mounted plastic housing, H x W X D: 180 x 180 x 75 mm;
protection class IP54, colour: light grey (~RAL 7035), leads outlets
either on top or at the rear of the housing.
11. It is possible to connect the weather monitoring unit to a remote
control module which contains optical indicators and potentiometers
for setting the desired sensitivity of the wind/rain sensors.
