Error Condition / Description / Corrective Action
Temperature Out of Range
Either the temperature zone is 2 degrees over the set point, or the temperature zone has
been disabled.
Corrective Action:
From the User Interface, check the Temperature Measure (Meas) and Setpoint (Set) values to
see if the Meas value is ≥ the Set value. Refer to "Starting the ta7000R in the Warm-Up Cycle"
in Chapter 2.
Vsig Out of Range (Lamp OFF ?)
During the Warm-up cycle the analyzer performs a system test of the RGD lamp. If the RGD
lamp is not within operating range this error will be displayed.
Corrective Action:
Check the support gases, and then perform the Warm-up procedure. Refer to "Starting the
ta7000R in the Warm-Up Cycle" in Chapter 2.
Carrier Pressure Out of Range
External carrier pressure is not within specified limits.
Corrective Action:
• Verify the external carrier pressure supply; adjust the pressure if necessary.
• Check the Carrier Gas tank to ensure there is an adequate supply.
Analog Signal Zeroing Error
The instrument has failed to Zero the detectors analog signal.
Corrective Action:
Contact AMETEK Service or qualified service representative for troubleshooting assistance.
Vsig Minimum Voltage Limit
This fault will occur if the RGD detector does not have the minimum Vsig (1000 mv) for proper
analysis. Typical Values are 1750–2250. Vsig cannot be above 2500.
Corrective Action:
Incorrect values could indicate that the RGD lamp is defective or has degraded due to normal
usage.
Calib Pressure Out of Range
Calibration gas pressure is not within normal operating range.
Corrective Action:
• Check the Calibration Gas requirements in the Specifications chapter, and check the Cali-
bration Gas tank to ensure there is an adequate supply.
• Adjust the pressure if necessary.
