These tests are intended to verifycompliance with production requirements of the standard for leakage. The test is to be conducted before painting the tank by applying an internal air pressure and using soap suds, or equivalent material, for the detection of leaks. For a horizontal or rectangular tank, the test gauge pressure is to be not less than 3 psi (21 kPa). If a leak should be detected during production testing, the leak shall be repaired. Tanks shall be retested until zero leaks are apparent during two (2) successive test periods. A record of the manufacturer’s testing shall be permanently maintained and available to the end user or customer.

C. The installing contractor shall test the system during start-up to assure the return pump system will move fuel overflow back to the source tank or to a collection system.

1. 1” NPT engine supply

2. 1” NPT engine return

3. NPT fitting for emergency vent, sized per the requirements o f NFPA 30

4. 1” NPT overflow.

5. 2“ NPT normal vent

6. 4 'A” square inspection port below electrical controls

Emergency vent cap shall be spring-pressure operated. Opening Pressure shall be 0.5 psig; full opening pressure 2.5 psig. Flow rate shall be marked on top o f each vent.

2.3 DESIGN REQUIREMENTS

A. Fuel Day Tank Control, Alarm and Status Display

1. The microprocessor-based electronic control module (ECM) shall be specified for controlof non-redundant pump operation. Where power is needed for the operation o f the fuel transfer pumps to deliver fuel to a generator set day tank, the pumps shall be connected to the legally required standby power system. The ECM shall receive a signal from a single electrical analog float sensor. The ECM shall be provided with the following indications: fuel level, alarm, function, and existing warning and shutdown conditions and be located within a Type 1 zinc-plated enclosure for indoor use. The lamps shall be high-intensity LED type. The lamp condition shall be clearly apparent under bright room lighting conditions. All warnings shall be provided with normally open and normally closed, dry contacts for remote annunciation (3 amps @ 120 VAC).

B. The following alarm, shutdown and status conditions are required as a minimum:

Fuel Level Display

a. Full - 100% Green LED Indicator

b. 95% - Green LED Indicator

c. 85% - Green LED Indicator

d. 75% - Yellow LED Indicator

e. 50% - Yellow LED Indicator

f. 25% - Yellow LED Indicator



g- 10% - Yellow LED Indicator

h. Empty - 6% - Red LED Indicator

Alarm Display

a. High Fuel - 106% or greater of Capacity

b. Low Fuel - 62% of Capacity

c. Critical Low Fuel - 6% of Capacity

d. Fuel within Containment

e. ECM Functional - Tank Fault

3. Function Display

a. Power on — This button activates the ECM after the Off button has beendepressed. On any initial power up condition, after a power outage, the ECM shall be in an on condition.

4. Remote Contact Connections

a. Tank Fault (ECM Functional)/Fuel in Containment (Shared)/Loss of Power

b. Critical High Fuel - 106% or greater of capacity

c. Pump Running Option — Indicating supply pump is in operation

d. High Fuel — 106% of capacity

e. Low Fuel — 62% of capacity

f. Critical Low Fuel — 6% of capacity

5. Mode

a. On - Power available to ECM

b. Off - Turns off power within ECM

c. Test - Shall force supply pump(s) to operate at time of start-up to verify overflow return pump is properly operating.

6. Start-up test switch shall test contacts for high, low, critical low, ECM functional and containment switch to assure wiring of remote contacts is correct.

7. Critical high-level automatic discrete shutoff switch shall stop supply pump delivery to the fuel day tank at the tank critical high liquid level. The critical high-level fuel switch shall be hard-wired to override any other alarms or signals received by the ECM.

2.4 PUMP OPERATION

C. For non-redundant pump operation, a single supply pump shall provide a minimum of 17 feet of vertical lift at sea level and shall activate when fuel level decreases to 87% of capacity and shall stop at 100% tank full. The single pump shall be sized to accommodate the Emergency/Standby Power System Generator Set and supplied as a 2 GPM pump with 1/3 HP, 115 VAC, 1 phase 60 Hz, thermally protected motor.

D. Return pump system shall be supplied when the Main Fuel Tank has a fuel pick up point that is higher than the fuel day tank overflow. The return pump operation shall be designed for



automatic unattended operation when the day tank level exceeds 110% of its normal capacity. The return pump shall be activated by a separate, critical high level switch. The return pump shall exceed the delivery capacity of the fuel supply to the fuel day tank. The ECM is hardwired to override any other indications given by the controller.

2.5 FUEL CONTAINMENT

A. The fuel day tank shall include a welded steel containment basin to prevent escape of fuel in theevent of a tank rupture, sized at a minimum of 150% of the tank capacity. The basin shall be primed and finish painted.

1. The containment tank shall consist of a welded heavy gauge steel structure. The containment tank shall feature a welded steel top with an emergency pressure relief vent as shown on drawing and sized per the requirements of NFPA 30 and UL 142 / ULC S601. Emergency vent cap shall be spring-pressure operated. Opening pressure shall be 0.5 psig; full opening pressure shall be 2.5 psig. Limits shall be marked on top of each vent. Leak detection switch shall be wired into the electronic control module (ECM). This will shut down the supply pump and motor in case of a fuel leak into the containment basin.
