and reactive voltage droop is not required, use one of the following
methods to eliminate the effect of the parallel operation transformer
within the voltage regulator.
- Install a unit/parallel switch across the current transformer
secondary, and close switch during single generator operation.
- Set the voltage droop resistor R4 to its minimum droop position.
- Where the generator will be operating singly, install a jumper across
terminals CT? and CT1.
UFL circuit 50/60 and 400 Hz selector J1: The underfrequency limit
components or V/Hz components are located on the voltage regulator
circuit board (see Figure 9). Parts comprising the UFL or V/Hz
components are shown in Figure 11. A jumper wire J1 eliminates the
effect of resistor R57. Removing the jumper J1 places R57 in the circuit.
60 or 400 Hz operation: Make certain the jumper wire is installed across
area marked J1. Wire is mounted on component side of circuit board and
ends of jumper wire are soldered on foil side of the circuit board.
50 Hz operation: Make certain the jumper wire is removed from across
area marked J1. Remove J1 by cutting each end of the jumper wire.
Voltage regulator fuse: The voltage regulator contains a 15 A normal
blow fuse in the voltage regulator input power circuit (see Fig. 1, 2
and 3). In applications where voltage regulator power requirements are
reduced, as when used with small generators where excitation is less than
given, a smaller fuse may be used. Never install a fuse larger than 15 A
and never install a delay-type fuse.
Accessory items: Accessory items provided with the generator system
must be connected as shown on the wiring diagram provided with the
generator set and the accessory item drawing or instruction. Observe
the precautions and general procedures that follow when connecting
accessory items.
Voltage shutdown (engine idle switch): The system can be equipped with
a switch to allow removal of excitation in an emergency or when the
prime mover must be operated at reduced speeds. This switch must be
placed in the input power line to the regulator (terminal P1 or P2).
Field circuit breaker: The ? eld circuit breaker must be of the type that
has separate terminals for the thermal element and the contacts.
The circuit breaker thermal element receives heat from either the ? eld
current or generator line current. Where it is heated by ? eld current, the
thermal element connects between the voltage regulator output and the exciter ? eld. Where it is heated by generator line current, the thermal
element connects to a current transformer located in one of the generator
load lines.
Auto/manual voltage control: The auto/manual voltage control option
includes the components described below. Connect the auto/manual
voltage control module as shown on the wiring diagram provided with
the generator.
- Three-position selector switch: When this switch is set to the AUTO,
power is fed across the switch contacts to the regulator input power
terminal P1 and P2. When the switch is set to MAN, power is fed
across the switch contacts to the manual voltage control circuit
recti? ers. OFF position opens input power to both the voltage
regulator and the manual voltage control recti? ers.
- Manual voltage control circuit: The manual voltage control circuit
consists of a full wave recti? er assembly and a manual voltage
control variac. The manual voltage control variac controls generator
output whenever the generator set is operated in the manual voltage
control mode of operation.
