Introduction

Small panel display unit and wind speed sensor with prealarm and alarm. With 20 mm digits (0.8” display unit). Ideal in conjunction with the Anemo4403 sensor.
Adaptable to a wide range of anemometer sensors. Pre-alarm (ALARM1) and Alarm (ALARM2). Designed for mounting on a 72 x 36 panel, such as in electrical cabinets.
Especially designed for construction cranes.
For installation on DIN RAIL see model WM44-DRM.

Features
DISPLAY:
 Wind data displayed with two 20 mm digits.
2 alarm indicator LEDs enabled “AL1 and AL2”.
Wind speed in km/h and mph.
Programming in kilometres/hour ( km/h) or in miles/hour (mph). P01
You can switch between km/h and mph at any time by pressing “Select”, a user accessible button.

ALARMS:
 The alarm is triggered when the programmed value is reached or surpassed and it has includes a delay to prevent false alarms due to short gusts.
The alarm is disabled when the wind speed drops below the programmed value and provided this condition persists for a minimum period.
When ALARM 2 is enabled ALARM 1 is disabled.
When ALARM 2 is enabled, the reading on the display will blink,
as a warning.		 Alarms can be programmed for the following: trigger values,
intermittent or continuous, interlocked (only alarm2).

The alarm outputs are through voltage-free relay contacts.
Choice between: on contact open or on contact close.

Possibility of alarm interlock 2. With the alarm disabled when the unit’s power supply is cut off.

ANEMOMETER SENSORS:
 Suitable for a wide range of sensors:

Power supply sensors: 20 V or 10 VDC, from the unit itself.

types : 3-wire and 2-wire (see examples on faceplate connections from the unit itself).

We RECOMMEND pairing the unit with our Anemo4403 model.

PRESET USER PROGRAM CONFIGURATION.
 In addition to user-programmed another, alternative programming can be saved in memory. This can be retrieved any time by going to the program step. P00 option 4.
