PDX DCEO Qualification Card

Define the following terms: Standby Generator

A secondary power source available if utility power experiences faults/inconsistencies/failure

Define the following terms as it relates to the Generator: Stop Mode

A manual mode that emergency stops the generator without a cool-down period

Define what the EMCP is and its importance to the generator

Electronic Modular Control Panel. Provides the interface for controlling the generator.

Discuss how the battery system works

The batteries are for the starter motor, to get the generator running. The battery system has 2 12 VDC batteries wired in series which are in parallel to 2 12 VDC batteries wired in series. This results in 4 batteries total.

Discuss how to verify that the enclosure louvers are operating as designed

During generator confidence tests, a visual inspection during the initial ramp up and the cool down of the generator will show the functionality of the louvers (opening and closing).

Discuss how to verify whether air filters are healthy or require replacing

There is a differential pressure gauge on top of the filters that will show a red indicator when the differential pressure has surpassed a preferred ratio, thus showing that the filters need changing.

Discuss normal operating parameters of a generator under load

Coolant temperature (<208 F)

oil pressure (>40 psi)

speed (1795-1805 RPM)

frequency (59-61 Hz)

amperage (0 A if unloaded)

voltage (475-485 V).

Discuss the different ways to switch the generator to the off position

Press "Stop" On the EMCP, Press E-stop, Open output CB. AMCOP > Mode selector > Manual > Generator start > OFF

Discuss the expected indications and response to the following casualties: Excessive exhaust smoke

If the line-up is on generator than the EOT should leave the generator as is. It is more important to keep the customers service operational and let the generator overheat. Amazon may have to pay an environmental fine and/or pay to fix/replace a generator but the customer comes first. If found during gen run exercises, escalate, stop gen exercise for that generator and engage the Gen team.

Discuss the expected indications and response to the following casualties: Fuel/oil/coolant spill

Indications are fuel/oil/coolant in an unwanted location. Using a Spill Response Kit and associated PPE: Stop the spread (apply drain covers and barriers). Stop potential ignition sources. If possible, isolate the source. Clean up the spill.

Discuss the expected indications and response to the following casualties: Generator output breaker tripping

-If generator is not carrying load, escalate. -If generator is carrying load, verify loads (racks and mechanical) transfer to alternate power supply. For sites equipped with a USB catcher system, verify Deadbus timer is fulfilled and ATC transfers load to 480V Catcher. Once load stability has been validated, escalate.

Discuss the expected indications and response to the following casualties: Generator high engine temperature

Escalate to On-all Manager, call the FOC and get a TT cut, notify Gen team. Await permissions for actions or until qualified engineer/ tech arrives on site to assess.

Discuss the expected indications and response to the following casualties: Generator low oil pressure

Escalate to On-all Manager, call the FOC and get a TT cut, notify Gen team. Await permissions for actions or until qualified engineer/ tech arrives on site to assess.

Discuss the expected indications and response to the following casualties: Generator low voltage output.

Basler relay will read low voltage (10% discrepancy) and will perform an open transition back to utility or put the line-up on battery if utility is unavailable at which point DCEO could put the entire line-up on catcher via the ATC 600 to prevent exhausting all battery power.

Discuss the expected indications and response to the following casualties: Generator low water jacket temperature

Indications are a low coolant temperature alarm. Escalate and contact the Gen Team for support.

Additional inspections: Verify heater is functioning and coolant is flowing. If heater is off or coolant isn't flowing, verify breaker positions (power panel and customer panel) are closed. Verify heater contact is operating normally. Inspect all associated wiring for damage or indications of electrical fire. If there are signs of an electrical fire, open associated breakers to secure power.

Discuss the expected indications and response to the following casualties: Over crank condition

Escalate to On-all Manager, call the FOC and get a TT cut, notify Gen team. Await permissions for actions or until qualified engineer/ tech arrives on site to assess.

Discuss the expected indications and response to the following casualties: Generator over speed condition.

Escalate to On-all Manager, call the FOC and get a TT cut, notify Gen team. Await permissions for actions or until qualified engineer/ tech arrives on site to assess.

Discuss the expected indications and response to the following casualties: PLC/AMCOP failure

The system will maintain current configuration and will be unable to provide automated response.

Discuss the expected indications and response to the following casualties: USB main generator breaker failing to close when commanded

AMCOP will go into AUTOFAIL.

If utility is available, load retransferred to Utility. Verify loads (racks and mechanical) are operating normally. Reset AUTOFAIL.

If utility is unavailable, verify loads (racks and mechanical) transfer to alternate power supply.

For sites equipped with a USB catcher system, verify Deadbus timer is fulfilled and ATC transfers load to 480V Catcher. Once load stability has been validated, escalate.

Discuss the expected indications and response to the following casualties: USB main generator breaker failing to open when commanded

AMCOP will go into AUTOFAIL.

If generator is available, load remains on generator. Verify loads (racks and mechanical) are operating normally. Reset AUTOFAIL.

If generator is unavailable, verify loads (racks and mechanical) transfer to alternate power supply.

For sites equipped with a USB catcher system, verify Deadbus timer is fulfilled and ATC transfers load to 480V Catcher. Once load stability has been validated, escalate.
