Greetings!

 

  Looks like we've survived another North East Winter...  Hopefully everybody's budgets aren't too damaged from all of the snow removal costs this year.
  I recommend during your next weekly generator test, that you pay attention to the engine temperature, before the start, as well as how long the engine cranks before it starts.  This unusually cold winter has taken a real toll on block heaters and batteries.  These are the two most important items to ensure that your equipment starts and accepts the building load in 10 seconds.  If there is any doubt, just give us a call....

 

Sincerely,

 JEFF.SIG

Battery Failures

"More common than you think" 

 

Unlike your car battery, the battery on your Emergency Genrator System needs to be treated a little differently.  Due to the nature of a generator system, it is vital that the engine-start-batteries be under a constant charge to ensure that they work when needed.  Normally, you would believe that having a constantly charged battery is a good thing...  However, this "necessary" charging is also what causes the lead in the battery to break down and collect at the bottom of the battery.  This build-up can cause the individual plates to short out and decrease the cranking capacity as more and more lead drops off of the plates.
  
This constant charge also causes the sulfuric acid to boil off and eventually leave a void of explosive hydrogen gas inside the molded case of the battery.  All this gas needs is a small spark to ignite a hydrogen EXPLOSION that is followed by a shower of sulfuric acid and lead shrapnel.

  
In light of the fact that the State of NJDEP is enforcing a "NO AUTO EXERCISE" mandate, the potential for injury of an unskilled attendant is huge!
  
Please! Please! Please! Take every precaution to avoid personal injury.  If you are a skilled technician you can check the individual battery cells for acid level - if you are an untrained attendant performing a weekly test - do your best to position yourself away from the engine batteries when you call the unit to start.batt.explosion2

 

If you are concerned that you may not be performing your weekly tests in a proper manner, please feel free to ask one of our technicians to walk you through the proper pre-start and start sequence to help avoid injury.  Lastly, keep in mind that R&J offers the new GEN+ system that will eliminate all of these concerns.

Engine Heater Failure

"The difference between starting and not starting" 

 

We spoil our cars with a 20 minute "warm-up" in the driveway before we take it out on a cold winter day, but we ask our generator to start at a moments notice and take an "uphill load" in under 10 seconds. The best thing we can do for the engine is to keep it as warm as possible before it starts.  By doing this, the unit will start faster, respond quicker and provide more stable output voltage as a result.  If you have an engine heater that resembles the picture below, there's a good chance that it's not working or soon won't be.  A good habit is to feel the engine block or heater hose prior to starting the machine to see if the engine temperature is warm (70 - 90 deg.)

*As always - turn the system off whenever your hands are in an area of rotating parts - Unit starts without warning and can cause injury or death if not handled properly.
