SCOPE
This Project Standard and Specification covers requirements for
machine andauxiliary system instrumentation and panels for
compressors and drivers. It alsodelineates the responsibilities of
the machinery vendor and the purchaser insupplying the
instrumentation.
Starting group panels are not covered by this Project Standard
and Specification.These are panels furnished on the machinery or
base plate by machinery
vendors with steam and gas turbines and gas engines to permit
starting ofauxiliaries and bringing the unit to minimum governor
speed.
DEFINITIONS AND TERMINOLOGY
Control house panels - panels in the main control house which
are used foroverall process operation.
Locally mounted instruments - those which are mounted on or near
themachinery, primarily on piping, but not on panels, and include
switches,thermocouples, and gages.
Local panels - those which provide mounting for all indicating
instruments andcontrollers for process and auxiliary system
variables which the operator requiresfor placing the machine in
process service.
DESIGN
1. Tables 1 through 6 list the instrumentation to be supplied,
the mountinglocation, and delineate the purchasers and vendors
areas of responsibility.Table 7 identifies the abbreviations used
herein.
2. Panels. One panel section shall be provided by the contractor
for each
compressor service. Space may be required for readout
instrumentationsupplied by the machinery vendor.
3. The purchaser shall specify the manufacturer and model for
the standardinstruments to be supplied by machinery vendors. To the
maximum extentpossible, they shall be the same as used in the rest
of the plant.
4. Upon instrument air or electrical power failure, regulating
devices includinggovernors shall fail in a position which insures
continued safe operation of thecompressor and driver. The design
shall provide the operator with the optionof a manual shutdown.

5. Speed governors for drivers shall be provided with a manual
speedadjustment for use during startup or a utility
interruption.
6. Group alarms. The local panel alarms on each compressor
service(compressor, gear, driver) shall actuate common alarms in
the control houseto call the (Control House) operators attention to
an alarm condition at themachine. One common annunciator shall be
furnished for the protectivesystem. Another common annunciator
shall be furnished for the remainingprealarms and alarm only
conditions. The prealarm/alarm only annunciatorshall have a realarm
feature that will permit any subsequent, but different,alarm to
annunciate and be acknowledged as soon as the previous alarm
hasbeen acknowledged. The local annunciator display must retain all
alarmconditions until cleared, independent of common alarm status.
A separateacknowledge and lamp test button shall be provided with
the localannunciator.
7. When specified instrumentation designated as located on the
local panel mayselectively or totally be located or duplicated on
the control house panel.
