7. Operation
7.1 Preparation for Starting
Operation
The EJX210B ange mounted differential pressure
transmitter measures the levels or densities of
liquids. This section describes the operation
procedure for the EJX210B as shown in Figure 7.1
when measuring a liquid level in an open tank.
NOTE
It is required to set security and network
information to enable the transmitter to be
connected to the Field Wireless Network. For
more details, refer to section 7.4 “Connecting to
the Field Wireless Network”.
(a) Conrm that there is no leak in the connecting
part of the transmitter mounting ange.
Remove the plastic dust cap placed in the
process connector (low pressure side).
(b) Insert batteries into the battery case, and install
to the transmitter. To insert batteries into the
battery case, be careful to polarity of batteries
and battery case. For details of Installation of
battery, refer to section 9.4.6 and 9.4.7.
Battery case is installed in the transmitter when
shipped from the factory, however, batteries are
sold separately and not included.
(c) Using the eld wireless conguration tool or
the device conguration tool, conrm that
the transmitter is operating properly. Check
parameter values or change the setpoints as
necessary.
Integral Indicator’s indication can be used
to conrm that the transmitter is operating
properly. For details on how to conrm, refer to
subsection 8.4 “Self-Diagnostics.”
ISA100 devices display self-diagnostic information
in an easy-to-understand manner using four
categories (Check function, Maintenance required,
Failure, and Off specication) according to NAMUR
NE107*.

NOTE
If any of the above errors are indicated on the
display of the integral indicator or the device
conguration tool, refer to subsection 9.5.3 for
corrective action.
■ Verify and Change Transmitter Parameter
Setting and Values
The parameters related to the following items are
minimum required to be set for operation, and set at
factory as specied in order. Conrm or change the
parameters if needed.
