6.1 Preparation for Starting
Operation
This section describes the operation procedure
for the EJX118B as shown in Figure 6.1 when
measuring liquid level in a closed tank, and
EJX438B as shown in Figure 6.2 when measuring
pressure in a 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 6.4 “Connecting to
the Field Wireless Network”.

Pressure Measurement
(a) Confirm that there is no leak in the connecting
part of each diaphragm seal mounting flange.
(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 8.4.4 and 8.4.5.
Battery case is installed in the transmitter when
shipped from the factory, however, batteries are
sold separately and not included.
(c) Using the device configuration tool, confirm
that the transmitter is operating properly. Check
parameter values or change the setpoints as
necessary.
Integral Indicator’s indication can be used to
confirm that the transmitter is operating properly.
For details on how to confirm, refer to subsection
7.4 “Self-Diagnostics”.
ISA100 devices display self-diagnostic information
in an easy-to-understand manner using four
categories (Check function, Maintenance required,
Failure, and Off specification) according to NAMUR
NE107*.
