Unpacking and Preparation
4.1
Unpacking and Inspection
Carefully unpack the units and retain the packaging to return equipment for
servicing or repair. If the equipment is damaged in any way, return it to ENVEA
(see the reverse of this manual) in its original packaging.
No responsibility for damage resulting from the use of non-approved packaging
will be accepted.
NOTE
Ensure all items and accessories specified are present. If not,
contact ENVEA or your local ENVEA representative.

Network Layouts
Standard Systems
Connect a single ENVEA sensor directly to a Standard Controller for a standard,
single-channel system
.
PRO Systems
Connect multiple sensors to the ProController either using network spurs or by
daisy-chaining the sensors. For medium to large systems, it is best to place the
control unit(s) in the network centre to minimize voltage drop along cable runs.
For large systems, you may need to boost power using a PSU Repeater (power
supply unit; see
on page 7 for details).

Prerequisites and Guidelines
4.3.1
Location Requirements
When selecting a mounting location for the sensor, the following should be
considered for optimum performance.
1.
Mount in the longest, straightest, unrestricted duct available.
2.
Ensure correct sensor grounding (see the section below).
3.
Avoid excessive vibration. Excessive vibration will affect sensor readings.
4.
Ambient or radiating temperatures in the vicinity of the mounting location
must not exceed 50 °C (122 °F).
Refer to the Installation Notes (TN004) for more details (see
SECTION
4.3.2
Cabling and Cable Routing
Where the network includes a network spur, the two cables between the sensor
and spur and the spur and control unit are of the same type (comprising four
cores with an overall screen, see
on page 8). When routing cables,
observe the following:
•
Ensure the cable sheath fully penetrates the cable entry gland.
•
Fit blanking plugs to unused cable entry glands.
•
Ensure cable entry glands are tightened to the cable.
