INTRODUCTION
The WM44-P wind speed and alarm unit, combine a
highly accurate indicator with dual set point alarm relays.
Specially designed to work with 4403 3-cup rotor, it’s also
compatible with most common wind sensors.
This instrument can be easily mounted in any instrument
panel, cabinet doors, and various industrial enclosures.
Specially developed for the tower crane sector.
Two programmable set points (ALARM1 & ALARM2).
FEATURES
PANEL VIEW:
Selectable alarm type : intermittent, continuous, latched..
3 digit LED display (14 mm digit height).
The alarm relays are equipped with free-voltage contacts
2 LED alarm status indicator (AL1 & AL2)
Each output relay, can be normally energized or deenergized at tripping
LED speed unit indicator (Mph or Km/h)
Press the “select” button on the unit to switch between a
readout in Mph or Km/h
Each set point, offers a user adjustable time delay to
determine when the relay should operate after the set point
has been exceeded so if the wind speed drops below the set
point speed before the time delay expires, then the alarm
relay will not be activated
When the wind speed falls and remains below the alarm set
point also for a brief period of time, the alarms will be
deactivated
In the latching mode, the alarm 2 relay energizes when
the wind speed set point is exceeded and remains
energized until the equipment is switched off
ANEMOMETRIC SENSORS:
Compatible with most common wind sensors:
Sensor power supply: 20V or 10Vdc
Type : 3 or 2 wires (see the wiring diagram)
RECOMMENDED working with our Anemo 4403 sensor
device
The activation of ALARM 2, deactivates ALARM 1
USER PREDEFINED INSTALLING CONFIGURATION
When ALARM 2 is on , the displays reading flashes to warn the
operator of imminent danger.
Apart from user programmed parameters, you can save
another alternative configuration, and you can recover it
as many times you want, going back to P00 program step
(option 4).
