Display Turned "Off - Macurco CX-6 Manuel D'instructions

Macurco CX-xx Manual (Rev-1.0) Eng
Clean Air – The CX-xx will flash between the current concentration of CO ppm and the current concentration of NO
ppm. The CO reading will start with a "C" and the NO
Fan Relay Level – When either the CO or NO
"Frd" period has elapsed, the display will flash between "FAn" and the current concentration of gases. The
sequence of display when the Fan Relay is activated is: "Fan", CO ("CXXX") reading, NO
Alarm Relay Level – When either the CO or NO
between "ALr" and the current concentration of gases. The sequence of display when the Alarm Relay is activated is:
"ALr", CO Reading ("CXXX"), NO
"On".
Trouble – When the device is in a trouble state, the display will display the "t" Error code (t001 for example) and the
Alarm Relay will activate. If the Trouble Fan Setting is enabled, the Fan Relay will activate. See Section 5.1.2 Trouble
Codes and Section 4.5.14 Select Trouble Fan Setting – "tFS"
NOTE: Trouble states related to the CO and NO
exists for the CO or NO sensor only, the display will alternate between the trouble code for the sensor in the
2
trouble state and the gas reading for the sensor in the normal state.
Calibration Due – When the Calibration Period functionality is enabled and the detector is within 1 month of the
calibration period, the Calibration Due message will be displayed. Calibration Due is indicated by "CdUE" (for CO
Sensor) and "ndUE" (for NO
will be "CdUE", CO reading, "ndUE", NO
Calibration Due is resolved only with a successful field calibration.
NOTE: If a Fan or Alarm Relay is activated during Calibration Due, 'Fan' or 'ALr' will be appended at the end of the
display sequence for calibration due.

4.3 Display turned "Off"

With the display ("dSP") setting turned "OFF", the detector will operate as follows:
Clean Air –The display does not show the CO or NO
Fan Relay Level – When the CO or NO
period has elapsed, the display will continuously show "FAn".
Alarm Relay Level – The display does not show the CO or NO
relay is activated. The buzzer will sound indicating "Alarm" if the buzzer is turned "On".
Trouble –When the device is in a trouble state, the display will display the "t" Error code (t001 for example) and the
Alarm Relay will activate. If the Trouble Fan Setting is enabled, the Fan relay will switch activating the relay. See
Section 5.1.2 Trouble Codes and Section 4.5.14 Select Trouble Fan Setting – "tFS".
Calibration Due – When the Calibration Period functionality is enabled and the detector is within 1 month of the
calibration period, the Calibration Due message will be displayed. Calibration Due is indicated by "CdUE" (for CO
Sensor) and "ndUE" (for NO
will be "CdUE", "ndUE".
