Installation
Site Selection and Mounting
The instrument is designed for wall mounting. The instrument should
be mounted at eye level and be easily accessible for operation and
service. Recommended mounting screws are M8 (5/16”) fasteners for
the instrument enclosure.
It is critical that the instrument be mounted as close as possible
to the sampling point to ensure a quick response time (within 2
to 3 meters (6 to 10 feet) of the sampling point).
Air Sentinel III Controller
The AccUView LED Ex will not function without proper air purging of
the enclosure. The Air Sentinel III Controller governs the power. See
Ekectrical Connections section.
Air Dryer/Filter
For proper operation, dry clean air must be supplied to the AccUView
LED Ex at pressures between 5.5 and 7 bar (80 to 101.5 PSI). The
dryer comes with fittings suitable for use with 6mm tubing. If using the
supplied fittings for installation, ensure that a proper thread sealant is
used.
Plumbing & Air Connections

The instrument is equipped to be plumbed using 6mm OD copper
or stainless steel tubing for the sample water inlet, drain and air. The
fittings are swagging type connections.
The emergency drain is not equipped for a connection.
Pressurized System
The AccUView LED Ex comes standard with a pressure regulator. The
regulator is rated for use up to 1380 kPa (200 PSI) and will lower the
pressure down to a pressure more suitable for use in the AccUView
LED Ex. If inlet pressures can exceed 325 kPa (47 PSI) use appropriate
tubing to connect to the AccUView LED Ex.
Electrical Connections
All of the electrical connections to the instrument are made at the
DIN rail connector. The connections are labeled beside the terminal
block and are self-descriptive. Please follow all local and government
recommendations and methods for installation of electrical connections
to and between the instrument and other peripheral devices.
Plugs are inserted into the 4-20mA/RS-485 cable bulkheads when
shipped to ensure a watertight seal. These plugs can be removed and
discarded when connecting to either of these connections.
The power cable bulkhead will accept cable diameters from 5.8mm
(.23”) up to 10mm (.395”). All terminals are designed to accept wires
in the range of 14 to 28 AWG. All wires should be stripped to a length
of 6mm (.25”). A strain relief strap is provided to reduce tension on the
power terminals.
It is the user’s responsibility to ensure that the water and air tight seal
is maintained after the connection has been wired for operation. If any
of the glands are not tightened properly around a cable or plug, the
ratings of the instrument will be jeopardized and there is a possibility of
creating a shock hazard.
