| 115 VAC motor is
an enclosed, permanent split capacitor induction type. The motor
is equipped with a thermal overload device that opens and resets automatically.
Standard motor requires 28-33 mfd
capacitor supplies by either the customer, or Duff-Norton at extra cost,
for loads up to 250 pounds. High speed motors require a 64-72 mfd
capacitor, also available from Duff-Norton. A capacitor box is
available on AC models only. |
|
220 VAC motor is
totally enclosed, permanent split capacitor induction type.
Load/no-load speeds are approximately equal. Equipped with thermal
overload device that opens and resets automatically. Standard
motor requires 10 mfd
440VAC, 60/50Hz metalized polypropylene capacitor supplied by
Duff-Norton. |
|
Controls
are also available for these actuator models as follows: |
- Control Package BAC -1 for 6420 Series
- Control Package BAC -2 for 7420 Series
|
|
Additional
Notes |
- Some actuator surface temperatures may reach
230°F at or near maximum allowable duty cycle.
- Do not operate actuator before
setting limit switches.
- Position hooded vent to prevent
moisture and dirt from entering the actuator.
- Actuators are not recommended for
applications where the unit can be jammed. Examples of jamming
include over traveling the limit switches and jamming the nut and
screw internally at the extreme ends of stroke, or driving the
actuator against an immovable object causing the actuator to
overload severely.
