Maintenance
Maintenance Modes
When the User Interface Maintenance Modes screen is selected, the
current Model 3095FT operation mode is indicated by the filled bullet
(see Figure 4-26).
To change to a different mode, select the desired mode, then select Ok.
Changing between maintenance modes typically takes 20 seconds to
complete.
The standard operation mode is “On-line Normal Operation.” When the
transmitter is in this mode, the audit trail data and the current
configuration can be read from the transmitter, but sending a
configuration to the transmitter and all sensor trim maintenance tasks
are prevented.
NOTE
All maintenance and configuration tasks, except On-Line Maintenance
Modes, are prevented when the WP (write protect) switch is set to ON.
See Page 2-4 to change this switch to OFF.
When the transmitter is in any of the four maintenance modes, sending
a configuration file and performing sensor trim maintenance tasks are
allowed. On-line maintenance is typically used when gas is flowing in
the line, while off-line maintenance is typically used when the gas flow
has stopped.
When the transmitter is placed into “Off-line Maintenance,” an event
log is generated, and all Model 3095FT flow calculations and logging
activities stop.
In addition, before the Model 3095FT User Interface Software places
the transmitter into off-line maintenance, a message is displayed.
