NOTE
If the transmitter searches the Field Wireless
Network for long time at low ambient
temperature condition, sometimes error “AL.70
LOWBAT” is displayed on the Integral Indicator.
Even though using new batteries, it can occur. It
occurs because of battery characteristics.
After joining to the Field Wireless Network, this
error will be cleared within one hour if battery has
no failure.
6.5 Shutting Down The
Transmitter
When shut down the transmitter, remove the battery
pack or set the transmitter to deep sleep mode by
the Device Configuration Tool.
NOTE
Whenever shutting down the transmitter for a
long period, detach the transmitter (diaphragm
seals) from the tank
•
Refer to subsection 8.4.4 “Replacing the
Battery Pack” for the battery pack removing.
•
When storing the instrument with a battery
pack inserted, it is recommended to put the
instrument into deep sleep mode to conserve
battery power. For details on how to switch to
deep sleep mode, refer to subsection 7.3.16
“Switching to the Deep Sleep Mode”.
6.6 Venting or Draining
Transmitter Process-
Detector Section
If condensate (or gas) collects in the transmitter
process-detector section, the measured pressure
may be in error. If it is not possible to configure the
piping for self draining (or self-venting) operation,
you will need to loosen the drain (vent) screw on the
flushing connection ring to completely drain (vent)
any stagnated liquid (gas).
However, since draining condensate or bleeding off
gas gives the pressure measurement disturbance,
this should not be done when the loop is in
operation.
