Det-Tronics EA2100CG Eagle 2000 Communication Gateway - Manual (Page 9)

OUTPUTS—
Digital communication, transformer isolated (78.5
Kbps). Calibrated 0 to 4095 digital output corresponds
to 0 to full scale current input from transmitter. Twelve
discrete points of status and diagnostic information are
also sent to the gateway. One SPDT sealed relay, rated
5 amperes resistive at 30 vdc, is used for remote annun-
ciation, response or reset of external devices.
POWER CONSUMPTION—
60 ma maximum during normal operation with relay
energized or during star tup (does not include
detector/transmitter power).
TEMPERATURE RANGE—
Operating: –40°F to +167°F (–40°C to +75°C).
Storage: –67°F to +185°F (–55°C to +85°C).
SHIPPING WEIGHT (Approximate)—
2.2 lb (1.0 kg).
DIMENSIONS—
See Figure 6.
DESCRIPTION
The Eagle Communication Module consists of a terminal
wiring board and a printed circuit board containing the
communication circuitry, mounted inside a water-tight,
explosion-proof aluminum junction box.
ADDRESSABILITY
Module identification (up to 250 nodes) is accomplished
by setting switches on an eight position DIP switch
located on the communication module circuit board.
STATUS LEDs
Three LEDs are located at the center of the communica-
tion module circuit board. (The cover must be removed
from the junction box in order to view the LEDs.)
The green LED serves as a power-on indicator and is
illuminated whenever power is applied. During normal
operation, only the green LED is on.
The red LED is used to indicate a calibration, power-up,
fault or alarm condition. The flashing rate of the red
LED indicates the following conditions:
Power-up = Pulsed at a 0.5 Hz rate
Calibration = Pulsed at a 1 Hz rate or on steady
Fault = Pulsed at a 4 Hz rate
Alarm = Illuminated continuously.
The red LED indicates the various steps of the calibra-
tion process. When the calibration begins, the red LED
flashes at a 1 Hz rate. When the zero part of the cali-
bration is completed, the LED is on steady. The span
gas is then applied to the sensor, the sensor input
increases, and the LED flashes at a 1 Hz rate. When
the span part of the calibration is completed, the LED is
again on steady. When the calibration gas is removed
and the sensor signal returns to below 4%, the calibra-
tion is complete and the LED turns off.
When power is applied to the system, the red LED flash-
es at a 1/2 Hz rate until the sensor signal is within 4% of
full scale for 10 seconds or 5 minutes has elapsed,
whichever comes first.
If the communication module has not been configured,
the red LED blinks at the 4 Hz rate.
The amber LED comes on when the service switch is
pressed. (Pressing the service switch will not affect nor-
mal operation.) The amber LED is provided for factory
diagnostic purposes and is not for use in the field.
Illumination of the amber LED normally indicates a fail-
ure in the communication chip. Replacement of the
communication module circuit board is required.
