[Analog electrical indicating instruments shall be in accordance with ANSI
C39.1 with semiflush mounting. Panel-mounted instruments shall [be the
manufacturer's standard][have 100-deg scales] with an accuracy of not less
than 2 percent. The instrument's operating temperature range shall be -20
to +65 degree C -4 to +150 deg F.]
[Electronic indicating instruments shall be 100 percent solid state,
state-of-the-art, microprocessor controlled to provide all specified
functions. Control, logic, and function devices shall be compatible as a
system, sealed, dust and water tight, and shall utilize modular components
with metal housings and digital instrumentation. An interface module shall
be provided to decode serial link data from the electronic panel and
translate alarm, fault, and status conditions to a set of relay contacts.
Instrument accuracy shall be not less than 2 percent for unit mounted
devices, and 1 percent for control room, panel mounted devices, throughout
a temperature range of -20 to +65 deg C -4 to +150 deg F. Data display
shall utilize LED or back-lit LCD. Additionally, the display shall provide
indication of cycle programming and diagnostic codes for troubleshooting.
Numeral height shall be [13 mm 0.5 inch] [[_____] mm inch].]
2.15.3
Parameter Display
Continuous indication of the tachometer, lubricating-oil pressure, and
safety system parameters shall be provided. A momentary switch shall be
specified for other panels.

BASE
**************************************************************************
NOTES: The diesel-engine pump drive can be equipped
so that it has its own base, or it can be on an
integral base with the pump and speed reducer. With
an integral base, coordination with the other
equipment specifications and the use of the
statement, "suitable holes for anchor bolts", should
be included in the plans and specifications.
Coordinate with the subparagraph VIBRATION ISOLATION
AND SEISMIC RESTRAINTS under paragraph SPECIAL
LIMITATIONS.
**************************************************************************
The base shall be constructed of structural steel. The base shall be
designed to rigidly support the engine, ensure permanent alignment of all
rotating parts, be arranged to provide easy access to allow changing of
lube-oil, and ensure that alignment is maintained during shipping and
normal operation. The base shall not permit skidding in any direction
during installation and shall withstand and mitigate the effects of
synchronous vibration of the engine and pump. The base shall be provided
with [suitable holes for anchor bolts] [[_____] mm inch diameter holes for
anchor bolts]. The entire engine assembly shall be capable of withstanding
the load imposed by earthquake forces.
2.17
MOTORS
Electric motors shall conform to the requirements of NEMA MG 1. Motors
shall have sealed ball bearings and a maximum speed of 1,800 rpm. Motors
shall have drip-proof frames; alternating current motors larger than 373 W
1/2 Hp shall be of the squirrel-cage induction type for operation on
