4.
Activate the reed switch. The red LED will blink at a
2 Hz rate for 3 seconds while the reed switch is
closed.
5.
After the reed switch has been closed for 3
seconds, the communication module records the
uncalibrated value in the calibration log and
calibrates the zero value. The calibrate LED goes
on steady.
6.
Apply the calibration gas.
7.
The calibrate LED blinks at a 1 Hz rate when the
input increases.
8.
Activate the reed switch. The red LED blinks at a 2
Hz rate while the reed switch is closed.
9.
The communication module records the
uncalibrated value in the calibration log and
calibrates the span value after the reed switch is on
for 3 seconds.
10. The calibrate LED goes on steady.
11. Remove the span gas and return the analog input to
normal.
12. Activate the reed switch. 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.
If the calibration is not completed within 12 minutes, the
previous calibration values are restored and the
calibration is logged as aborted. The calibrate LED
flashes at a 4 Hz rate.
Sensor Replacement
WARNING
The hazardous area must be de-classified prior to
removing a junction box cover with power applied.
1.
Open the junction box cover and press the sensor
replacement switch.
2.
The calibrate LED on the communication module
flashes at a 1 Hz rate, indicating it is ready for the
zero input.
3.
Replace the sensor and apply the zero input (4 ma).
4.
Activate the reed switch. The red LED blinks at a 2
Hz rate for 3 seconds while the reed switch is
closed.
5.
The communication module records the
uncalibrated value in position one of the calibration
log and calibrates the zero value. The calibrate
LED goes on steady.
6.
Apply the calibration gas.
7.
The calibrate LED blinks at a 1 Hz rate when the
input increases.
8.
Activate the reed switch. The red LED blinks at a 2
Hz rate for 3 seconds while the reed switch is
closed.
9.
The communication module records the
uncalibrated value in the first register of the
calibration log and calibrates the span value.
10. The calibrate LED goes on steady.
11. Remove the span gas and return the analog input to
normal.
12. Activate the reed switch. 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.
