INTRODUCTION
The WM44-SS Wind speed Display, is a device with high
accuracy with 2 programmable threshold output. It is
particularly designed to work with ANEMO4403 but it can
work also with a huge range of anemometer.

The device can be easy mounted on a front door of electric
panel.
Specially developed for the tower crane sector.

2 programmable thresholds (ALLARM 1 and ALLARME 2).

FEATURES
PANEL VIEW:

Selectable alarm type : intermittent, continuous, latched..

2 digit LED display (20 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 (Km/h or Mph).
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)

The activation of ALARM 2, deactivates ALARM 1

RECOMMENDED working with our Anemo 4403 sensor device

When ALARM 2 is on , the displays reading flashes to
warn the operator of imminent danger.

USER PREDEFINED INSTALLING CONFIGURATION
Apart from user programmed parameters, you can save
another alternative configuration, and you can recover it as
many times you want, going back to P01 program step
(option 4).
