Troubleshooting and solutions depending on the equipment
[3]
1. How to determine the cause and resolve trouble based on the detected error display of the
AE-200/AE-50/EW-50
The following shows the details, causes, and solutions for the error codes of errors detected at the detection source by the
AE-200/AE-50/EW-50.
First confirm that there is no mistake for each setting.
*
The detection address displayed on the error monitor and in the error history is the address of the controller that detected the error.
Description and method of
Error code
detection
Version combination error
Error detected when the
versions of the
AE-200/AE-50/EW-50
are not a compatible
0092
combination for the
apportioned electricity
billing function.
System configuration
change warning
Error detected when the
apportioned data is not
restored when the
AE-200/AE-50/EW-50
0093
is replaced while the
apportioned electricity
billing function of the
AE-200 is enabled.
"Charge" license not
registered
Error detected when a
license is not registered to
any of the
AE-200/AE-50/EW-50
0094
while the apportioned
electricity billing function is
enabled for an AE-200
without an apportioned
electricity billing function
license.
Warning - possibility of
damaged metering device
Error detected when the
state of the
measurement value of
the meter not counting
up continues for at least
three days even though
the operation amount of
the air-conditioning units
is being counted up
while the apportioned
0095
electricity billing function
of the AE-200 is
enabled.
Cause
1)
The apportioned electricity billing
function of the AE-200 has been
enabled but the AE-50/EW-50 is a
version that is not supported (version
earlier than 7.23) by the apportioned
electricity billing function.
1)
The AE-200 and AE-50/EW-50 back
up each other's data with the
apportioned electricity billing function
of the AE-200, but the backup data
no longer matches after the
AE-200/AE-50/EW-50 was replaced.
1)
With the apportioned electricity billing
function of the AE-200, the "Charge"
license needs to be registered to all
the AE-50/EW-50 under the control
of the AE-200, but there is equipment
to which it is not registered.
1)
There is a wiring connection failure
between the electricity meter and PI
controller. (When a PI controller is
used)
2)
There is a wiring connection failure
between the electricity meter and the
built-in PI of the AE-50/EW-50.
(When meter pulse input (PI) of the
AE-50/EW-50 is used)
3)
There is an error with communication
between the PI controller and
AE-50/EW-50.
4)
An electricity meter with pulse output
of 10 kWh/pulse or higher is being
used.
5)
The carried-over data was not
cleared after the time period of the
unit price was deleted.

Check procedure and remedy
The apportioned electricity billing function of
the AE-200 does not operate while this error
code is displayed.
Update the AE-50/EW-50 to Ver.7.23 or
later.
Note: The equipment recovers from the error
and then data collection resumes after
a maximum of 30 minutes elapse.
For how to update the software, refer to "VIII
[1] AE-200/AE-50/EW-50 update
procedure."
To prevent a loss of backup data, the
apportioned electricity billing function of the
AE-200 does not operate while this error
code is displayed. Perform an apportioned
data restore for the new
AE-200/AE-50/EW-50.
Note: The equipment recovers from the error
and then data collection resumes after
a maximum of 30 minutes elapse.
For how to restore apportioned data, refer to
AE-200 Instruction Book (Apportioned
Electricity Billing Function).
The apportioned electricity billing function of
the AE-200 does not operate while this error
code is displayed.
Register the "Charge" license to all the
AE-50/EW-50 under the control of the
AE-200.
Causes 1 to 3) Check the wiring connections
to ensure there is no
connection mistake or
broken/disconnected wire.
Cause 4) If an electricity meter with a large
pulse output such as 10 kWh/pulse
is used, three days or longer may
be required to add one pulse
depending on the operating
conditions of the air-conditioning
units. If changing the pulse output
of the electricity meter is possible,
change it to a value such as 1
kWh/pulse.
Cause 5) Perform the carried-over data
clearing process for the deleted
unit price.
For how to clear the carried-over
data, refer to AE-200 Instruction
Book (Apportioned Electricity
Billing Function).
Note: The equipment recovers from the error
and then data collection resumes after
a maximum of 30 minutes elapse.
