WARNING:
The Atrato is designed to be powered from either USB or external DC power.
When connected to both supplies, there is potential for damage to the flow meter
from ground loops or direct shorting of any non-isolated power supplies. The user
must ensure the 0V from the USB and the negative terminal of the DC supply are not
at different voltages, by correct earthing or isolation.
The Atrato can be programmed using the USB connection via a computer.
The Atrato can operate solely on USB power via the computer or a high quality USB2 power
supply (e.g. RS 9076255 5V 5W supply), the meter display will function, as will the relay and
pulse outputs (require target power).
For full functionality, including the analog outputs, 15-24VDC external power is required.
The unit will work with systems from Windows XP onwards.
The maximum connector cable size is 2.5mm (22-14AWG); for ease of assembly we
recommend 1mm maximum. Care should be taken when terminating the wires as the
conductors should be stripped to 4 to 5mm maximum and the wire ends must be pushed fully
into the connector before tightening. These cables pass through a slot cut in the aluminium
housing. Please ensure that no bare conductors are in contact with the surface of the
connector strip prior to closing the housing.
NOTE:
The Titan Interface Software allows the user to test the outputs from the flow meter.
