2301A APPLICATIONS
The 2301A Load Sharing and Speed Controls are designed for u in electric generator systems where multi-unit load sharing is desired. 2301A controls may be ud with diel, gas or gasoline proportional to the fuel tting needed to attain the desired speed/load. Position feedback from the actuator is not required. The 2301A controls are compatible with Woodward SPM-A Synchronizers,
SPECIFICATIONS
Power Supply
High 90–150 Vdc or 88–132 Vac, 12 W, Low voltage of 75 Vdc
(60
Vac) and high voltage of 200 Vdc (140 Vac) for up to 5
minutes
Low 20–40 Vdc, 12 W--After power-up, a supply voltage as low
as
10 Vdc or as high as 77 Vdc for up to 5 minutes
Control Characteristics
Steady State ±1/4 of 1% of rated speed
.Within ±5% of rated load with speed ttings matched
Load Sensing
90–240 Vac, 45–66 Hz; maximum load: 3 VA per pha
3–7 A at full load; maximum load: 1 VA
Speed Ranges (switch lectable) • 500–1500 Hz • 1000–3000 Hz
• 2000–6000 Hz • 4000–12000 Hz
1–30 Vac; maximum load: 1 at 1 • 0–200 mA, 30–40 Ω• 0–400 mA, 30–40 Ω
• 0–20 mA, 0–600 Ω, or • 0–200 mA, 60–80 Ω for
tandem actuators Adjustments
.Sets engine speed over specified range. External remote input accessible.
Sets engine idle speed at 30%–100% of rated speed
Idle to rated speed: 0–10 cond acceleration time
Rated to idle speed: 0–10 cond deceleration time with
通行证申请书special decel ramp. (Rated to idle is instantaneous without
special ramp.)
Start 25%–100% of specified maximum actuator current.
Start fuel limit cannot be ud with rever-acting controls. Gain, Ret, Sets dynamic respon. Adjustable to accommodate die
l or gas engines, or turbine systems.
Provides calibration of the ba load level on an individual
generator or the load sharing feature when two or more
generators are paralleled. Provides 0%–10% reduction in reference speed between no
load and full load for ba load conditions.
Options
-5 to +5 Vdc for ±3% speed change or-1.5 to +1.5 Vdc for ±1% speed change; maximum load: 100W

The minimum-fuel signal is an optional means for a normal
shutdown. Opening an external contact in ries with terminal 17 and th
e control’s dc switch power will nd a minimum-fuel signal to the actuator. The droop contact is wired in ries with the auxiliary circuit
breaker contact and terminal 14, and the control’s dc switch
power. Isochronous operation is lected when both the droop contact and the auxiliary circuit breaker contact are clod. Failed Speed Signal Override..An external contact to override the failed speed protective
circuit when required for start-up.
Idle/An external contact to accelerate from idle to rated speed when the contact is clod. Rated-to-idle ramp is available only on
special 2301A controls.
