Manual 26659
ProAct P-Series FL Position Controller
Woodward
17
The ProAct P-Series FL requires a voltage source of (18 to 32) V (dc), with a
current capacity of at least:
15 A for the Model II
15 A for the Model III
20 A for the model IV
If a battery is used for operating power, an alternator or other battery-charging
device is necessary to maintain a stable supply voltage.
Special care must be taken when wiring the ProAct P-Series FL.
Figure 2-4. Correct and Incorrect Wiring to Power Supply
To withstand an engine start when actuator power is from the starting batteries,
the actuator will work with a supply voltage as low as 8 V (dc). However, the
actuator will not function completely within specifications. During the low voltage,
the ProAct P-Series FL will NOT meet the transient response times or the
maximum torque output.
Voltage range
Normal operation: (18 to 32) V (dc)
Transient/starting: (8 to 40) V (dc) for 1 minute
The ProAct must be fused:
Model II: 15 A fast blow
Model III: 20 A fast blow
Model IV: 25 A fast blow
The input power must be fused. Failure to fuse the ProAct P-Series
FL
could, under exceptional circumstances, lead to personal injury,
damage to the control valve, or explosion.
Wire Requirements:
For battery connections (+Bat and –Bat):
Model II: 1.0 mm²/16 AWG for distances up to 8 meters
Model III: 1.0 mm²/16 AWG for distances up to 5 meters
Model IV: 1.0 mm²/16 AWG for distances up to 4 meters
