Woodward EPG Electrically Powered Governor Models 512/524 and 1712/1724

Woodward EPG Electrically Powered Governor Models 512/524 and 1712/1724

The EPG is used to control the speed of diesel, gas, and gasoline engines. It can
also control the speed of gas turbines. Installation of EPG actuators is simple
because they require neither mechanical drive nor hydraulic supply.
The EPG handles prime movers with mechanical loads and generator loads
equally well. Generator sets which will be paralleled, however, require additional
appropriate switch gear, current and potential transformers, and the Woodward
Generator Load Sensor.
An EPG is a three-component system, requiring a magnetic pickup, speed
control, and actuator.
A battery charger must be used to keep the battery charged. Maximum steady
state current consumption is 4 A for the 12-volt models (512/1712), and 3 A for
the 24-volt models (524/1724).

Product Service Options 18144100983
The following factory options are available for servicing Woodward equipment,
based on the standard Woodward Product and Service Warranty (5-01-1205)
that is in effect at the time the product is purchased from Woodward or the
service is performed:
• Replacement/Exchange (24-hour service)
• Flat Rate Repair
• Flat Rate Remanufacture
If you are experiencing problems with installation or unsatisfactory performance
of an installed system, the following options are available:
• Consult the troubleshooting guide in the manual.
• Contact Woodward technical assistance (see “How to Contact Woodward”
later in this chapter) and discuss your problem. In most cases, your problem
can be resolved over the phone. If not, you can select which course of
action you wish to pursue based on the available services listed in this
section.

Replacement/Exchange
Replacement/Exchange is a premium program designed for the user who is in
need of immediate service. It allows you to request and receive a like-new
replacement unit in minimum time (usually within 24 hours of the request),
providing a suitable unit is available at the time of the request, thereby
minimizing costly downtime. This is also a flat rate structured program and
includes the full standard Woodward product warranty (Woodward Product and
Service Warranty 5-01-1205).
This option allows you to call in the event of an unexpected outage, or in
advance of a scheduled outage, to request a replacement control unit. If the unit
is available at the time of the call, it can usually be shipped out within 24 hours.
You replace your field control unit with the like-new replacement and return the
field unit to the Woodward facility as explained below (see “Returning Equipment
for Repair” later in this chapter).
Charges for the Replacement/Exchange service are based on a flat rate plus
shipping expenses. You are invoiced the flat rate replacement/exchange charge
plus a core charge at the time the replacement unit is shipped. If the core (field
unit) is returned to Woodward within 60 days, Woodward will issue a credit for
the core charge. [The core charge is the average difference between the flat rate
replacement/exchange charge and the current list price of a new unit.]
