Page 20: Gas Alarm Conditions & Advice
Gas Alarm conditions & Advice: If the current gas concentration reading meets or exceeds either alarm set points, the transmitter alarm function activates. When the alarm condition no longer exists, the transmitter exits alarm mode and enters normal mode operation. The Oxygen Low and/or High gas alarm set points are user settable for either enrichment and/or deficiency alarm as desired. -
Page 21: Fault Alarm Conditions & Advice
Fault Alarm conditions & Advice: In the event of a fault alarm condition, the fault alarm triggers activating the connected field device. The transmitter indicates the type of fault condition occurred. Under the fault alarm condition, the fault alarm is activated. Table: 06 Fault conditions Fault... -
Page 22: Calibration
Calibration Guidelines: ➢ Calibration accuracy is never better than the calibration gas accuracy. We recommend a premium grade calibration gas. Do not use gas cylinder beyond its expiration date. ➢ Calibrate the sensor after the installation and the new sensor before use. - Page 23 to shift the cursor to the next position. When none of the digit is blinking, key K2 is used to execute the password. CALIBRAT After entering the correct password (0001), MODE LCD/OLED shows this prompt. It means now it is in calibration mode.
