Chapter 2. Error Codes
E5: Amplitude Error
Problem:
The signal amplitude exceeds the limits programmed in the
SETUP-SIGNAL
submenu of the
User
Program
.
Cause:
Solid or liquid particulates may be present in the flowcell. Poor coupling for clamp-on transducers.
Action:
Refer to Chapter 3,
Diagnostics
, to correct any flowcell problems.
E6: Cycle Skip, Acceleration
Problem:
The acceleration exceeds the limits programmed in the
SETUP-SIGNAL
submenu of the
User Program
.
Cause:
This condition is usually caused by poor flow conditions or improper transducer alignment.
Action:
Refer to Chapter 3,
Diagnostics
, to correct any flowcell and/or transducer problems.
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 <600 ohms for the
Slot 0
analog outputs or is <1000 ohms for an analog
outputs option card in
Slot 1
.
E8: Analog In Error
Problem:
This message indicates a temperature input error.
Cause:
The temperature exceeds the specified limits for the analog/RTD inputs option card or no input device is
connected.
Action:
Check the temperature transmitter and the connecting cable. Refer to Chapter 1,
Calibration
, and
recalibrate the analog/RTD inputs option card.
E9: Totalizer Overflow
Problem:
The totalizers are unable to keep up with the total accumulated flow signals.
Cause:
The programmed units/pulse value is too small.
Action:
Select a larger number of units/pulse value.
E13: Volumetric Overflow
Problem:
This error code message indicates that the present measurement exceeds the range of the meter.
Cause:
A 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
MGAL/M
instead of
GAL/M
in the
Channel-System
menu. See Chapter 2,
Initial Setup
, of
the
Startup Guide
for instructions.
