2-3
DigitalFlow™ GC868 Service Manual (1 and 2-Channel)
2.8 E6: Cycle Skip,
Accel.
Problem:
The acceleration exceeds the limits programmed in the SETUP submenu
of the User Program.
Cause:
This condition is usually caused by poor flow conditions or improper
transducer spacing.
Action:
Refer to Chapter 3, Diagnostics, to correct any flowcell and/or
transducer problems.
2.9 E7: Analog Out
Error
Problem:
The current in the analog output circuit exceeds the limits for the analog
output port.
Cause:
The output load exceeds the specified limits for the analog output port.
Action:
Make sure the output load is <550 ohms for the Slot 0 analog outputs or
is <1000 ohms for an analog outputs option card (slots 1-6).
2.10 E8: Temp In
Problem:
This message indicates a temperature input error.
Cause:
The temperature exceeds the specified limits for the analog inputs
option card.
Action:
Check the temperature transmitter and the connecting cable. Refer to
Chapter 1, Calibration, and recalibrate the analog inputs on the option
card.
2.11 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.
2.12 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.
2.13 E11: Not Used
This error code message is not currently in use.
2.14 E12: Not Used
This error code message is not currently in use.
2.15 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.
2.16 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.
