OPERATION
7.1 Preparation for Starting
Operation
The EJX210A flange mounted differential pressure
transmitter measures the levels or densities of liquids.
This section describes the operation procedure for the
EJX210A as shown in Figure 7.1 when measuring a
liquid level in an open tank.
(a) Confirm that there is no leak in the connecting part
of the transmitter mounting flange.
Remove the plastic dust cap placed in the process
connector (low pressure side).
(b) Turn ON power and connect the communicator.
Open the terminal box cover and connect the
communicator to the and – terminals.
(c) Using the communicator, confirm that the transmit-
ter is operating properly. Check parameter values or
change the setpoints as necessary.
See IM 01C25T03-01E (BRAIN communication) or
IM 01C25T01-01E (HART communication) for
communicator operation. If the transmitter is
equipped with an integral indicator, its indication
can be used to confirm that the transmitter is
operating properly.
