Macurco GD Operation Manual
tYYY
t001 Missing Sensor (At Power Up only)
At each power-up it checks if that ABC is disabled. If it is not disabled it will try to set it to
t002 disable. If it fails it will trigger trouble t002.
t004 EEPROM bad checksum.
t008 Modbus communication error (during normal operation).
t010 Bad EEPROM
t020 Bad Factory calibration.
t040 Never Factory calibrated.
t080 Bad pressure during factory calibration
t100 Under range. Reading is under -100ppm for more than 15 seconds
t200 Sensor Expired
t400 Trouble Pressure Sensor
t800 Board not tested
NOTE: For trouble codes over 080 the display will alternate between t_1 and t00 for t100 and between t_2 and t00
for t200.
If the error mode repeats frequently, check for continuous power and proper voltage. If power is not the problem
and a unit has repeating error conditions, it may need to be returned to Macurco for service, per these User
Instructions.
If the error mode indicates "Sensor expired" see the Sensor Life Reset section of these User Instructions.

5.2 Sensor Poisons

The gas sensor in the detector is designed with extreme sensitivity to the environment. As a result, the sensing
function may be deteriorated if it is exposed to silicones, such as the common oil and lubricants with silicon
compounds used as additives in machinery, halogen compounds, which are used in fire extinguishers and Freon
used in refrigerants, organo-metallic compounds, sulfur compounds, chlorine compounds, acetylene, olefins or high
concentrations of combustible gas.

5.3 End-of-Life Signal

The GD-6 has a long life, non-replaceable catalytic bead sensor. Five (5) years after the GD-6 is installed the sensor
end-of-life signal will be activated indicating that the GD-6 has reached the end of its typical usable life. The end-of-
life signal will cause an error code t200 "Sensor expired". See Error Codes section. The end-of-life signal can be
silenced for 48 hours by pressing the "ENTER/TEST" button or by temporarily dropping power to the unit. The end-
of-life signal provides the user an opportunity to test and/or calibrate the sensor assuring that it is still performing
within acceptable parameters though the sensor is nearing the end of its expected life. The silence function will
continue to be available for 29 days after the GD-6 initiates the initial end-of-life signal. After this 29-day period the
GD-6 can no longer be silenced and the sensor must be calibrated and the sensor life reset or the GD-6 detector
replaced.
