INSTALLATION
The Controller has been thoroughly inspected
and tested prior to shipment from the factory.
Nevertheless, it is recommended that the instrument
be re-checked prior to installation. Upon receipt,
inspect the outside of the enclosure to make sure
there are no obvious signs of shipping damage.
Loosen the screws on the enclosure lid and open
the front panel. Visually inspect the interior of the
enclosure for loose wires or components that may
have become dislodged during shipment.
The Controller should be centrally located in the
facility (preferably outside of the mechanical room)
and should be easily accessible for visual monitoring
and servicing. This is the "split architecture design"
for safety of the operator. Dirt, grease, and oils can
adversely affect the operation of the Controller. This
Controller should be installed out of direct sunlight in
a clean, dry area that is not subject to temperature or
humidity extremes. Installation in a mechanical room
is acceptable provided reasonable environmental
conditions exist. If there is a question, consider
installing the unit outside of the mechanical room in a
cleaner area of the facility.
The Controller should be installed plumb and level
and securely fastened to a rigid mounting surface.
The enclosure utilizes four mounting holes designed
for #6 (or M3.5 or M4) pan head fasteners (included).
Mounting holes are located in the four corners of
the enclosure, accessed by opening the front panel.
Install and adjust the screws as necessary to hold the
unit securely against the mounting surface.
The Controller enclosure features M20 two cable
glands that are intended for power entry. If conduit
is preferred simply remove one of the M20 glands
and install a suitable ½" conduit adapter. Locate the
AC power and Ground on the power input terminal
block. Secure the incoming AC power neutral (white/
blue) and live (black/brown) and ground wires to the
appropriate terminals using a screwdriver on the press
to release tabs as shown below.
The Controller is connected to Hansen gas detectors
using a shielded twisted pair instrument cable
(Belden 3106A or equivalent). The maximum distance
between the furthest gas detector and the Controller
is 1000 feet (1372 m) when only using MODBUS
communications. The available distance is less when
using the Controller as the power supply for gas
detectors. The total power available for gas detectors
is 51W. Careful attention to voltage drop over distance
with a suitable wire gauge employed is also required.
Use any of the remaining cable glands to gain access
to the interior of the unit. The RS-485 communication
wiring between the gas detector and the Controller
must be connected in the following manner:
1. Locate the RS-485 connector in the gas detector.
2. Connect one lead of a twisted shielded pair to the
"B" connection point; note the wire color.
3. Connect the second wire to the "A" connection
point; note the wire color.
4. Connect the ground to the "GND" connection point
5. Connect the shield or drain wire to the "SH"
connection point.
Locate the RS-485 connectors in the Controller. The
left RS-485 connector is for downstream "child"
devices (includes a dedicated shield position) and the
right RS-485 connector is used to connect to "parent"
devices upline, such as building management controls.
A second RS485 connector allows a Building
Management System (BMS) to communicate with the
Controller via MODBUS protocol. The connection is
established using a shielded twisted pair cable such
as Belden 3106A. Use any of the remaining service
cable glands to gain access to the interior of the
Controller. Locate the RS485 upline connector, secure
the wire leads to the connector in the orientation
as displayed on the board. Check to make sure the
polarity matches the wiring to the BMS. The shield
connection should only be grounded at the BMS
device and should not be connected at the controller.
