NOTE
The Controller and enclosure must be
connected to earth ground.
For ordinary locations when entry is required to
operate the equipment, the cabinet should be
a dead-front construction and 16-gauge cold-
rolled steel. The door lock system shall accept
different keys for entry. An Authorized Persons
key and a Person-in-charge key will allow entry
into the cabinet. The cabinet should contain a
window to view the Controller’s text display and
LED indicators.
NOTE
For any selected enclosure, the
enclosure must conform to all applicable
regulations and requirements.
NOTE
The Trouble signal must be located in an
area where it is likely to be heard.
Classified locations require the appropriate
hazardous rated enclosure. It is recommended
that operators/switches be installed in the
enclosure. This avoids the need to declassify
the area in order to operate the Controller.
Regulations require that key switches be
installed for certain operations. An appropriate
window should be part of the enclosure in order
to allow an operator to view the text display and
LED indicators.
NOTE
If an enclosure does not have a keyed
entry, a special tool is required to gain
entry into an enclosure.
Det-Tronics offers several approved (FM/CSA/
ATEX/CE) hazardous area enclosures that have
Eagle Quantum Premier equipment installed in
the enclosure. Contact Det-Tronics for further
information.
MOUNTING
The Controller is designed for direct panel
mounting or DIN rail (optional) mounting. See
“Specifications” section of this manual for
mounting dimensions.
NOTE
Clips for DIN rail mounting are available,
but must be specified at the time of
ordering.
NOTE
A minimum clearance of 4 inches
between the Controller and nearby
equipment is required to provide room
for wiring and ventilation.
SERIAL INTERFACE BOARD
A Serial Interface Board is available for the
EQP Controller. See Figures 3-8A and 3-9 for
details on the electrical connections.
ETHERNET INTERFACE BOARD
An Ethernet Interface Board is available for the
EQP Controller. See Figures 3-8B and 3-9 for
details on the electrical connections.
WIRING
Power Wiring
CAUTION
Input voltage at the Controller must be 18
Vdc minimum to ensure proper operation.
It is important to consider both the wire gauge
and the distance from the Controller to the
power supply. As the distance between the
Controller and the power supply increases,
so must the diameter of the power wiring in
order to maintain a minimum of 18 Vdc at the
Controller.
IMPORTANT
To ensure proper operation of devices,
the voltage input to the device
(measured at the device) must be within
the range indicated for that device in the
"Specications" section of this manual.
Electrical Connections
Figure 3-8 shows the location of wiring
connectors on the Controller module. Figure
3-9 identifies individual terminals.
Connector P1, Terminals 1 to 4 —
24 Vdc Input Power
Connect the power supply to terminals 1 and
2 of the Controller. Terminals 3 and 4 must also
be connected to power.
