1. Notes on Handling
The YVP110 advanced valve positioner is fully
factory-tested upon shipment. When the YVP110 is
delivered, visually check that no damage occured
during the shipment.
1.1 Nameplate
The model name and configuration are indicated
on the nameplate. Verify that the configuration
indicated in the “Model and Suffix Code” in Chapter
7 is in compliance with the specifications written on
the order sheet.

1.2 Transport
To prevent damage while in transit, leave the
positioner in the original shipping container until it
reaches the installation site.
1.3 Storage
When an extended storage period is expected,
observe the following precautions:
(1) If at all possible, store the positioner in factory-
shipped condition, that is, in the original
shipping container.
(2) Choose a storage location that satisfies the
following requirements.
• A location that is not exposed to rain or water.
• A location subject to a minimum of vibration or
impact.
• The following temperature and humidity range
is recommended. Ordinary temperature and
humidity (25°C, 65%) are preferable.
Temperature: –40 to 85°C
Humidity: 5 to 100% RH (at 40°C)
(3) The performance of the positioner may be
impaired if stored in an area exposed to direct
rain and water.
To avoid damage to the positioner, install it
immediately after removal from the shipping
container. Follow wiring instructions in this
manual.
1.4 Choosing the Installation
Location
Although the advanced valve positioner is
designed to operate in a vigorous environment,
to maintain stability and accuracy, the following is
recommended:
(1) Ambient Temperature
It is preferable not to expose the instrument
to extreme temperatures or temperature
fluctuations. If the instrument is exposed to
radiation heat a thermal protection system and
appropriate ventilation is recommended.
(2) Environmental Requirements
Do not allow the positioner to be installed
in a location that is exposed to corrosive
atmospheric conditions. When using the
positioner in a corrosive environment, ensure
the location is well ventilated. The unit and its
wiring should be protected from exposure to
rainwater.
(3) Impact and Vibration
It is recommended that the positioner is
installed in a location that is subject to a
minimum amount of impact and vibration.
1.5 Use of a Transceiver
Although the positioner is designed to resist
influence from high frequency noise, use of a
transceiver in the vicinity of installation may cause
problems. Installing the transmitter in an area free
from high frequency noise (RFI) is recommended.
