2.3 Electric connections
The Orion owmeter has been designed to be connected to ARAG devices (computers, screens,
displays) but can also be connected to equipment made by other manufacturers as long as they
are designed for owmeters of this typology.
ARAG is not liable for damage to the system, persons, animals or things caused by
incorrect or inadequate installation of the owmeter.
In the event of damage to the owmeter, caused by incorrect or unsuitable assembly,
any form of guarantee is automatically rendered null and void.
The connections of the Orion owmeter on devices not provided by ARAG are indicated in tables
3a and 3b.
There are two different types of owmeter connectors:
STANDARD CONNECTOR (ORION Code 462xAAxxxxx)
Colour Position Connection
Black 1GND
Red 2+12 VDC
Green 3Signal
(square wave)
DEUTSCH®CONNECTOR (ORION Code 4622AB61717)
Colour Position Connection
Green 1Signal
(square wave)
Black 2GND
Red 3+12 VDC
2.4 Hydraulic connections
For connection to the system, use appropriate ttings (Ref. ARAG General catalogue).
Avoid bends and constrictions before connections and on tubes.
Regarding connections, use tubes and ttings properly sized for the operating pressure of
the system.
The tightening of hose tails should be made with special metal clamps ensuring perfect
sealing even at high pressures.
The connection by means of threaded ttings should be done taking operating pressure
into account.
CAUTION: For the implementation on already operating systems it is necessary to
follow all safety rules described herein. System assembly and start-up must be carried out
by expert personnel according to the safety rules so as to ensure the same safety level of
the system the owmeter is going to be installed in.
