USER’S MANUAL
1. INTRODUCTION
This manual is a guide to the correct use of the display VA-1.
This set has been specially designed to accomplish with the ITC “MIE-AEM-2” regulation for lifting and
maintenance equipment, referring to tower cranes in constructions or other applications.
This device reads through the RS485 cable the information sent by the ITOWA anemometer and it
has been designed to display the instant speed of wind (fig 1). When the wind reaches 50 km/h, the
display activates one relay (AV) and the notice led (Aviso). When the wind reaches 70 km/h, the
display activates one relay (AL) and the warning led (Alarma). (Figure 3 and Figure 1 respectively)
A connection RS485 to an anemometrical sensor ITOWA is allowed, by realizing an initial test. This
means that all the displays are connected and all the relays are activated during 4 seconds. The
connection type will be automatically selected (RS485 or Sensor). In case it did not detect any
connection during 12 seconds, the message failure “Er. 6” (see attached table of display messages)
would appear and the relays of notice AV (aviso) and warning AL (alarma) would be activated.
Whenever there is a wrong connection or a break of any cables of the sensor, the display shows
message “Er 5” (see attached table of display messages) and the notice AV relay blinks.

6. RECYCLING
INFORMATION FOR THE PROPER MANAGEMENT OF ELECTRIC AND ELECTRONIC
DEVICES (RAEE)
The equipment’s refuses should never be mixed with general refuses. These refuses can be
delivered, without any extra cost, to the centers of refuse collection. For further information, please
contact your local authorities.
To recycle an electronic device separately from the general refuses avoids possible negative
consequences for the environment. Furthermore, it allows a proper recycling process for all the
pieces.
This implies both energy and resources saving.
This symbol is marked in all products. It highlights both the obligation to collaborate with the
refuse collection and the warning of not using traditional containers for the elimination of the products.
