1.2 Control Room Environment
This section describes environmental conditions of the control room to operate the
system safely, and stably over a long period of time.
It is recommended that user have the control room environment assessment. For the
assessment, contact Yokogawa if necessary.
Temperature and Humidity Limits
SEE
ALSO
See “Table of Equipment Installation Specications” in this section, for the temperatures and humidity limits for
operating and storing this equipment.
When bringing the equipment into a location where allowable operating temperature is set
from another location where the temperature exceeds the allowable operating range, following
precautions are necessary:
• The equipment should reach the ambient temperature according to the requirements for the
temperature change rate, keeping it unpacked from its case. At that time, be careful not to
let condensation form on the equipment.
• Once the equipment reaches the allowable operating temperature range, leave it for about
three hours before operation.
Under normal operation, the rate of change of ambient temperatures should be within 10°C/h. All
the equipment should be kept out of direct sunlight.
Condensation
Prevent condensation. If condensation occurs, or its trace is found on the control room, contact
Yokogawa.

See “Section 2.3 Storage” for more information.
Vibration
Vibration in the control room should be limited as follows:
• For vibration frequency up to 8.4 Hz: Limit displacement amplitude to 1.75 mm or less.
• For vibration frequency over 8.4 Hz: Limit acceleration to 4.9 m/s
2
or less.
The following is the relationship of the vibration frequency, displacement amplitude, and
acceleration:
