2-4 Error Codes and Screen Messages
E9: Press In
Problem:
This message indicates a pressure input error.
Cause:
The pressure exceeds the specified limits for the analog
inputs option card.
Action:
Check the pressure transmitter and the connecting cable.
Refer to Chapter 1,
Calibration , and recalibrate the
analog inputs on the option card.
E10: Special Input
Problem:
This message indicates a special input error.
Cause:
The special input exceeds the specified limits for the
analog inputs option card.
Action:
Check the special transmitter and the connecting cable.
Refer to Chapter 1,
Calibration , and recalibrate the
analog inputs on the option card.
E11: Not Used
This error code message is not currently in use.
E12: Not Used
This error code message is not currently in use.
E13: Over Range
Problem:
This error code message indicates that the present
measurement exceeds the capacity of the meter.
Cause:
An internal mathematical overflow has occurred in either
the volumetric or mass flow calculations.
Action:
Select larger measurement units or a shorter time interval
for the current measurement parameter. For example,
choose
KSCF/M
instead of
SCF/M
. See the Startup Guide
for instructions.
E14: Totals Overflow
Problem:
The totalizers are unable to keep up with the total flow
signals.
Cause:
The programmed units/pulse value is too small.
Action:
Select a larger number of units/pulse value.
E15: Equation Limit
Problem:
The steam measurement may not be within 1% accuracy.
Cause:
The temperature or pressure reading is outside the
accuracy specification of the GC868 steam equations.
Action:
Adjust the pressure reading to within the range of
139.9685 kPa to 2242.9435 kPa (20.8717 to 326.4482
psi), or the temperature reading to within the range of
373.1500°K to 810.9278°K (100 to 212°F).
