7. Operation
7.1 Preparation for Starting
Operation
This section describes the operation procedure for
the EJX530B as shown in figure 7.1.
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”.
NOTE
Check that the process pressure tap valves,
drain valves, and stop valves are closed.
(a) Follow the procedures below to introduce
process pressure into the impulse piping and
transmitter.
1) Open the tap valve (main valve) to fill the
impulse piping with process fluid.
2) Gradually open the stop valve to introduce
process fluid into the transmitter pressure-
detector section.
3) Confirm that there is no pressure leak in
the impulse piping, transmitter, or other
components.
(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 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 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
specification) according to NAMUR NE107*
* NAMUR NE107 “Self-Monitoring and Diagnosis of Field
Devices”
