Battery Faults and Alarms
To clear a battery fault or alarm, check battery voltage and replace the battery if necessary.
For information about accessing and replacing the battery, refer to Section 12.6.2.
11.5.6
Fault and Alarm Pulse Outputs
The meter can provide a pulse output when a fault or alarm is present. This feature is configurable in the
Volume Configuration
screen of the Dresser MeterWare software. To display the
Volume Configuration
screen, select the
Configuration
screen in the MeterWare software, and then click
Volume
(refer to the
Dresser MeterWare Software Manual
).
Pulse Output 1 and Pulse
Output 2 provide a Form A (Normally Open) pulse when ‘Fault’ is selected for
the output. Form A fault/alarm pulses can be configured to either send a single latched pulse or a
continuous pulse string when they occur (refer to the
Dresser MeterWare Software Manual
). A pulse
output is provided every thirty (30) seconds when a fault or alarm is present. The pulse width is selectable
as 50, 150, or 250 ms.
Unlike the other two (2) pulse outputs, Pulse Output 3 is a dedicated Form B (Normally Closed) switch and
is configured for a 500 ms pulse. There are only two settings for the pulse output:
When a fault of any kind is present:
•
The pulse outputs for Compensated and Non-Compensated Volume do not pulse out.
•
Any pulse output configured to be a fault pulse functions as an alarm/fault pulse output.
If an alarm is present, all pulse outputs continue to perform as configured.
If the 10C25 meter is configured to use the Fixed Temperature Under Fault function and a Temperature
Fault occurs, the Compensated and Non-Compensated Volumes:
•
Continue to increment and be displayed on the LCD screen.
•
Are logged in the Logged Data Reports.
If the 10C25 meter is not configured to use the Fixed Temperature Under Fault function and a
Temperature Fault occurs:
•
Non-Compensated Volume only continues to be logged in the Non-Compensated Volume Under Fault
register.
•
NCVOLFLT
displays on the LCD screen (if the Non-Compensated Volume Under Fault parameter is
enabled at time of unit configuration).

Logging Features
The meter records information for the Data Logs and Audit Logs to store information about the activity
and settings for the meter. These logs are stored in non-volatile memory and are maintained during a
power failure. These logs can be downloaded for reference.
