L:\wpb_\wpb_emp1\W1200.13\p.m. Project #1\SECTION 16201-Indoor Generator and ATS.doc

A. Provide unit to shunt trip the remote main breaker and prohibit engine start

or run. The excitation voltage for the shunt trip shall come from the DC

battery circuit. See the drawings.

1. Shunt trip the main remote breaker. Provide contacts on main

breaker to remove excitation voltage.

2. Shunt trip the mainline circuit breaker. Provide contacts on main

line breaker to remove excitation voltage.

3. Stop engine and prohibit restart.

3. Lock out generator and allow reset via the engine control panel.

2.12 DAY TANK

A. Provide frame-mounted day tank with a minimum volume for 2-hour fuel

supply at 100% base-load operation.

B. Provide continuous day tank level control probe arranged to monitor fuel

level in percentage of volume. Probe shall be designed to control high-

level/return pump on, high-high level/system shut-down, and low-level

level.

C. Provide 1” day tank supply flow control manifold connection to the

existing diesel supply system. Manifold shall contain at a minimum one

(1) normally closed solenoid valve that shall open when the tank demands

fuel, isolation ball valves for the solenoid, by-pass tee with ball valve,

basket type strainer, and flow switch. Piping shall be schedule 40, ASTM

Grade A-53 black steel pipe. Threaded fittings and unions will not be

accepted.

D. Provide tank mounted fuel return pump capable of pumping against the

static head in the fuel tank and return line. In no case shall the minimum

capacity be less than 10 GPM at 50 psig when operating with diesel fuel.

E. Provide factory assembled “packaged” duplex fuel oil pump set per

generator and engine manufacturer’s recommendation and specification.

F. The control strategy for the day tank demand system, fuel return pump,

and fuel supply pumps shall be microprocessor-based, shall have sufficient

I/O to accomplish all necessary control functions, and may be integrated

into the Generator Control Panel.
