4.2.7 IF THE MODULE DOES NOT DISPLAY THE CORRECT %PPM 1. Power cycle the unit. 2. Recalibrate the sensor. 4.2.8 IF THE DISPLAY SHOWS ‘F’ – SENSOR MISSING OR BAD SENSOR 1. Power down the unit. 2. Open the enclosure and unplug the sensor assembly from the transmitter board. 3. Plug the sensor back into the transmitter board carefully and ensure a secure fit. 4. Check all other connections. 5. Power up the unit. 4.2.9 IF THE MODULE SHOWS “***CALIBRATION REQUIRED***” 1. Calibrate the module. 4.2.10 IF THE DISPLAY SHOWS ‘H’ (OR L) THEN THE LOCAL HIGH OR LOW ALARM IS ACTIVE 4.2.11 IF THE DISPLAY SHOWS “M” – NOT CALIBRATED 1. Calibrate the module. 4.2.12 IF THE DISPLAY SHOWS “C” – CALIBRATION MODE 1. Complete calibration and exit to operating mode. 4.2.13 IF THE DISPLAY SHOWS “S” – SENTRY CONNECTION 1. Check connections with Sentry Controller 4.2.14 DIAGNOSTIC LEDS LED 1 = 1 Hz Heartbeat normal, 2 Hz Panic Error 2 = Computation process 3 = 1 Hz Heartbeat normal 4 = HART or Sentry comms activity Page: 28 Model 5100-XX-IT Toxic Gas Sensor Module 8.
