Det-Tronics EA2100CG Eagle 2000 Communication Gateway - Manual (Page 38)

CALIBRATION ALGORITHM E
(Type Codes 23 and 24)
1. Apply the zero input (4 ma).
2. Activate the reed switch or input 1 on the communica-
tion module. (See Figure 33.) The red LED blinks at a
2 Hz rate while the reed switch or input 1 is closed.
3. After the reed switch has been closed for 3 sec-
onds, the calibrate LED on the communication mod-
ule flashes at a 1 Hz rate, indicating that the calibra-
tion has begun. The calibrate bit in the communica-
tion module status word is set.
4. The communication module records the uncalibrat-
ed value in the calibration log and calibrates the
zero value. The calibrate LED goes on steady.
5. When the LED has been on steady for at least 3
seconds, the calibrate LED turns off and the cali-
brate bit in the status word is reset.
If the calibration is not completed within 12 minutes, the
previous calibration values are restored and the calibra-
tion is logged as aborted. The calibrate LED flashes at
a 4 Hz rate, the calibrate bit in the status word is reset
and the calibration fault bit is set.
CALIBRATION ALGORITHM F
(Type Codes 15 to 22)
Normal Calibration
1. Activate the reed switch on the communication
module. (See Figure 29.) The red LED blinks at a 2
Hz rate while the reed switch is closed.
2. After the reed switch has been closed for 3 sec-
onds, the calibrate LED on the communication mod-
ule flashes at a 1 Hz rate, indicating that it is ready
for the zero input. The calibrate bit in the communi-
cation module status word is set.
3. Apply the zero input (4 ma).
4. Activate the reed switch on the communication
module. The red LED will blink at a 2 Hz rate while
the reed switch is closed.
5. After the reed switch has been closed for 3 sec-
onds, the communication module records the uncal-
ibrated value in the calibration log and calibrates
the zero value. The calibrate LED goes on steady.
6. Apply the span input.
7. The calibrate LED blinks at a 1 Hz rate when the
input increases.
8. Activate the reed switch on the communication
module. The red LED blinks at a 2 Hz rate while the
reed switch is closed.
9. The communication module records the uncalibrat-
ed value in the calibration log and calibrates the
span value.
10. The calibrate LED goes on steady.
11. Remove the span input and return the analog input
to normal.
12. Activate the reed switch on the communication
module. The red LED blinks at a 2 Hz rate for 3
seconds while the reed switch is closed.
13. The calibration is complete. The calibrate LED
turns off and the calibrate bit in the status word is
reset.
If the calibration is not completed within 12 minutes, the
previous calibration values are restored and the calibra-
tion is logged as aborted. The calibrate LED flashes at
a 4 Hz rate, the calibrate bit in the status word is reset
and the calibration fault bit is set.
