Generator Monitoring Information

FleetZOOM FZ300 Generator Monitor

Banks, hospitals, data centers, commercial buildings and municipal water and wastewater pumping stations all depend on reliable power for their operation. When utility power fails, commercial standby power generators provide backup power to many types of essential enterprises. A FleetZOOM emergency generator monitor ties into the generator control panel which provides settings for the mode of the generator. Electronics inside the generator control automatically start the generator when power fails. Once the generator has reached operating RPM and the generator control unit determines the unit is "ready to load," the automatic transfer switch will disconnect the building's load from the utility power grid and connect generator power to the building.

Most generator installations include a remote annunciator panel that displays the status of the generator and generator switch. Signals displayed on the remote annunciator can be monitored remotely with the FleetZOOM FZ300 equipment monitoring unit. In some cases, such as hospitals and other public facilities the NFPA and fire code mandate the use of a generator annunciator panel visible to a staffed location inside the building which serves as their remote generator monitor. Because power is critical to many operations, a backup generator monitor and continuous real-time status and alarm information from the generator is a necessity for a business or enterprise to function. Facilities managers directly benefit from the FleetZOOM generator monitor for their standby generators with improved reliability, reduced generator maintenance costs and fewer issues with backup power.

Commercial standby generators vary in size, but generally, large enterprise backup power generators range from 100 kW to 2MW, with 200 kW to 500 kW being the most common. Larger backup power requirements are met by generator paralleling. With a paralleled power generation system, multiple generators are synchronized at the generator control. They are wired together (in parallel) so their power output can be multiplied. It only takes two generators to create a paralleled system, but systems with up to eight generators are common for large data centers. The FleetZOOM FZ300 genset monitor can be tied together with both the generator annunciator and the network control that manages the paralleled generators. Paralleled generator systems are complex so continuous status monitoring by facility maintenance personnel is essential to reliable operation.

Monitoring of Power Generators from FleetZOOM

Although most of these larger gensets are Diesel generators, natural gas is used at some installations. Natural gas does not provide as much energy from combustion as Diesel, therefore the same size engine operating on natural gas will not be able to provide as much power output as the Diesel generator. An FZ300 used as a Diesel generator monitor works the same as the natural gas version, but FleetZOOM devices used for Diesel generator monitoring can also report fuel level if a level transducer is installed, or report low fuel through use of a digital input if a low fuel level switch is installed in the fuel tank.

Preventative maintenance for gensets is another important reliability and longevity boosting practice for generators. Most local generator service companies offer preventative maintenance agreements, or PMAs for generator maintenance. These agreements are a big part of any good generator management program, and are tailored to each generator application and involve scheduling oil changes based on generator run time and the time between oil and filter changes. Other maintenance, such as Diesel fuel treatment, emissions testing, load testing and scheduled engine maintenance are often included. Centralized monitoring of service intervals with automatic reminders, based on both run time and calendar date, are important components of the generator monitoring system offered by FleetZOOM. Coordinating these services is especially beneficial for mobile generators where the FleetZOOM FZ330 can be used for generator tracking. Savvy generator owners often request that their generator service company incorporate generator remote monitoring service into their preventative maintenance agreements.

Due to the size of the engines used in typical commercial backup gensets, a large generator battery is required. In fact, most of the larger gensets require multiple banks of generator batteries to start the genset. If the batteries are not in top form, the generator will fail to start. This happens more frequently than some facility managers would like to admit. Emergency generator monitoring systems like the FleetZOOM FZ300 will watch the generator batteries which are essential for reliable starting of the genset when it is needed. This degree of standby generator monitoring goes beyond simple voltage monitoring. Ideally the monitoring of the batteries should be done continuously, but specifically while the generator is starting, so a determination can be made by an intelligent remote monitoring unit of battery strength. With genset monitoring, generator maintenance personnel can be notified at the first sign of weakness during engine cranking so the batteries can be replaced if needed. It's amazing that typical backup generator systems costing hundreds of thousands of dollars fail to meet the needs of their owners simply because batteries are not properly maintained, but this is a common failure point in emergency power systems. Monitoring battery status 24x7 is essential to reliable standby power availability that is ready for utilization at any given moment. An emergency generator remote monitor like the FleetZOOM FZ300 will cover the batteries, status, power, and report any alarms should they occur.

FleetZOOM Remote Annunciator Panel Monitoring

Maintaining warm engine coolant and oil temperature for standby generators while the engine is off is essential for their reliable fast loading in emergency situations. Most people understand that high coolant temperature when it comes to your car is a bad thing, but on a standby generator, low coolant temperature is equally as bad because in some cases the generator won't be able to start fast enough to take over the emergency load within the amount of time it was designed to do. Low coolant temperature is a key fault to watch for on gensets and you'll usually find that signal shown prominently on the generator remote annunciator. Most standby generators have a block heater powered from utility line power. This block heater keeps the entire engine block, including coolant and oil, at an elevated temperature so the engine can be utilized at full rated load within seconds after starting. If the block heater fails, the engine will endure much greater mechanical wear during startup, causing more costly overhauls, and even worse, there is an increased chance the generator won't start fast enough to meet the needs of the emergency power load. The FleetZOOM remote generator monitoring system immediately notifies generator operators about these overcrank or "fail to start" conditions. In most generator installations a low coolant temperature alarm is displayed on the generator monitoring panel and notifies generator operators when the block heater has failed and no longer maintains the engine block at elevated temperature. This is another important status signal that a real time, continuous generator monitoring system that FleetZOOM provides keeps tabs on, and immediately notifies generator maintenance personnel of the issue.

The use of a standby generator monitor adds more life to power generation equipment and reduces maintenance costs. A complete standby generator installation is a complex system, both in terms of mechanical and electrical components. Common preventable, or easily corrected, problems include low fuel level, dead or weak batteries, block heater failure, leaving the generator in manual start or "not in auto" mode. All of these conditions can be continuously monitored with the FleetZOOM wireless generator monitoring kit. If any of them occur, alarm generator maintenance personnel immediately are alerted so problems can be addressed before the generator needs to provide backup power. With the web based generator monitoring software that is part of FleetZOOM service, generator owners can keep tabs on their generators in real time, 24x7x365.

With so many preventable and easily resolved issues that impact standby generator reliability, it makes sense for genset owners to utilize wireless generator monitoring. FleetZOOM provides a complete system for the remote monitoring of generators that provides continuous real time monitoring and instant notifications at the first hint of a problem with your genset.

FZ300 Generator Monitoring System Hardware

The FleetZOOM FZ300 remote terminal unit (RTU) is a compact cellular transceiver for monitoring generators that sends live data to the generator monitoring web portal, providing real-time status and alarms.

The FZ300 features 14 digital inputs that are connected to dry contacts (relays) on the generator control or other interface. In addition to alarming on status changes, the system keeps track of generator run time and engine start events, providing remote annunciation of generator set status.

The FZ300 monitors the voltage of the generator's cranking batteries which enables the system to alarm on low battery conditions.

No software to buy, install or maintain; all mapping and data features are accessible over the FleetZOOM monitoring web site from any computer with Internet access.

Proactive service reminders are automatically generated and sent as equipment reaches service intervals based on run-time. Service logs and manuals available over the monitoring web site reduce paperwork and automate record keeping while providing up to the minute service records for all of your monitored equipment.
