Decimal Alarm
Bit Value Type Alarm Condition / Description and Suggested Corrective Action
4 16 Fault f: Probe temperature too low
The Heated Acid Gas Sample Probe temperature is below its Too Cold setpoint.
This alarm may occur during a cold start, but will clear after the temperature zone
has stabilized within its normal operating range.
Note: This alarm is used only by analyzers equipped with (and controlling) the
optional Heated Acid Gas Sample Probe.
Corrective Action:
• From the Temperature Control dialog box, check the Probe Setpoint and
Too Cold setpoint.
Take appropriate safety precautions, open the Lower Enclosure, and:
• Check the heater control circuit:
Check fuse F3 on the AC Distribution board (see Figure 6-14). Replace if
necessary.
• Check the Probe RTD – inside the Probe Heater Assembly – for a short or an
open circuit. Contact AMETEK to verify operation before removing this
component.
Refer to the Heated Acid Gas Sample Probe Installation and Maintenance
Guide for a maintenance procedure to replace this part.
5 32 Fault f: Probe temperature too high
The Heated Acid Gas Sample Probe temperature is above its Too Hot setpoint.
Note: This alarm is used only by analyzers equipped with (and controlling) the
optional Heated Acid Gas Sample Probe.
Corrective Action:
• From the Temperature Control dialog box, check the Probe Setpoint and
Too Hot setpoint.
• Check the ambient temperature around the analyzer; if it is higher than the
Too Hot setpoint, adjust the surrounding temperature to within the Probe
measuring range (see “Temperature Control” in Chapter 4).
Take appropriate safety precautions, open the Lower Enclosure, and:
• Check the heater control circuit:
Check fuse F3 on the AC Distribution board (see Figure 6-14). Replace if
necessary.
• Check the Probe RTD – inside the Probe Heater Assembly – for a short or an
open circuit. Contact AMETEK to verify operation before removing this
component.
