6.2 Zero-gain Adjustment
IMPORTANT
After performing zero-gain adjustment, do not
power off the transmitter immediately. Turning off
the power within 30 seconds resets the zero-
gain adjustment value to the value before the
adjustment.
Furthermore, setting the sensor type
automatically resets the zero-gain adjustment
value to the factory setting
When the preparation for starting operation is
completed, perform a zero-gain adjustment as
necessary.
This transmitter is fully calibrated at the factory and
basically re-cablibration is not necessary; however,
users can make the zero-gain adjustment.
The zero-gain adjustment of this transmitter can be
performed by the following steps.
1) Apply the lower limit of process temperature
to the sensor. Set the lower limit temperature
using the device configuration tool.
2) Apply the upper limit of process temperature
to the sensor. Set the upper limit temperature
using the device configuration tool.
The zero-gain adjustment should be performed
when the input to the temperature sensor is
stabilized.
For details on the zero-gain adjustment, refer to
subsection 7.3.13 Input calibration.
6.3 Starting Operation
Ensure that the installation, the wiring, the network
connection, and the action of the transmitter are
correct before starting operation.
IMPORTANT
Close the terminal box cover and the amplifier
cover. Screw each cover in tightly until it will not
turn further.
6.4 Connecting to the Field
Wireless Network
■ Preparation work prior to connecting to a
field wireless network
This transmitter does not need to be connected
with a physical wire. Instead of physical wiring, it
is necessary to set the field wireless devices to
communicate with before installing the transmitter.
This procedure is called a provisioning.
This transmitter supports provisioning via infrared
communication using a provisioning device and
can be securely connected to a network. If the
provisioning information is not set, the transmitter
cannot be connected to the field wireless network.
Provisioning:
Provisioning is work to set the security and
network information to enable the transmitter
to be connected to the field wireless network.
This transmitter supports a provisioning method
using infrared communication.
For details on provisioning using a provisioning
device, connecting to a field wireless network and
the setting procedure, refer to the User’s Manual,
FieldMate Versatile Device Management Wizard
(IM 01R01A01-01E), YFGW710 Field Wireless
Integrated Gateway (IM 01W01F01-01EN), and
YFGW410 Field Wireless Management Station (IM
01W02D01-01EN).
