REPLACING THE SENSOR ELEMENT
The Hansen Gas Detectors come with a pre-calibrated
sensor elements which maintain the sensor’s gas
type and calibration information. Replacement
sensor elements come pre-calibrated as well for the
refrigerant type and calibration level. To replace the
gas detector’s sensor element:
1. Power-down the gas detector.
2. Using a 5/32” (4mm) hex key/ allen wrench (not
included), remove the lid and disconnect the
ribbon cable from the sensor element.
3. Remove installed sensor element from lid by
holding onto the housing and turning counter
clockwise 90°. Take care not to apply excessive
force to the sensor element’s circuit board. When
the square tab of the sensor housing is aligned
with the lock icon, firmly pull the module to
remove it from the housing.
4. Install the new sensor element by aligning the
square tab with the lock icon before firmly
pressing it into the enclosure. Taking care not to
apply excessive force to the sensor element’s
circuit board, rotate the sensor element clockwise
90° (or until the triangle icon aligns with the lock
icon on the lid).
5. Connect the ribbon cable (to the sensor element
and transmitter) and close the lid.
6. Ensure gasket is aligned correctly and tighten
the lid using the supplied hardware in an “X”
pattern. Tightening torque should be limited to
hand tight and should be uniform.
7. Power-up the gas detector.
8. After start-up sequence has finished, check
sensor response (bump test).
RESET SYSTEM TO FACTORY DEFAULT
SETTINGS
To reset system to factory defaults, remove lid and
hold TACT#1 and TACT#2 simultaneously for 30
seconds. Instrument will restart to confirm factory reset.
Alarm Delay
A time delay for the operation of the relay and alarm
horn can be adjusted.
Alarm Buzzer
Alarm Buzzer can be reconfigured to up to 15 minute
delay. Alarm Buzzer is >72dB at 4 default factory
setting is enabbled, with option to disable
BLUETOOTH INSTRUCTIONS
The Hansen Gas Detector has a Bluetooth® feature to
allow a smartphone to communicate with the individual
detector. This feature allows the user to confirm the
target gas, the target gas level, log the sensor readings,
and initiate calibration/bump tests. To start this option,
user would need to download the Hansen Gas Detector
App from either Google Play Store or Apple Store.
SENSOR SETUP
In order to utilize the Bluetooth® option, sensors will
need to be setup individually thru the APP. To do this:
1. Enable Bluetooth® discovery by tapping MAG#1
for 1-second. After 10-seconds, device will indicate
that it is discoverable with audible heartbeat until
it has been paired, discovery has timed-out or has
been cancelled
2. Launch the Hansen Gas Detector APP and click the
Bluetooth® icon at the bottom of the screen to
initiate a scan
