actuators have a maximum ambient operating temperature

rating of 65°C.

3c. Check duty cycle (frequency of operation). See above for

details.

3d. Ensure that actuator is not continuously stalled.

3e. Ensure that all wiring connections are secure.

Problem 4:

Motor runs continuously in spring return direction

after actuator output shaft has stopped.

Instructions:

4a. Adjust spring return side travel cam/switch so that the

cam trips the switch before the shaft stops motion.

turn.

Instructions:

solenoid.

Note:

Standard Surepowr actuators are manufactured with thermal

overload protectors in series with the motor common. Should

any of the above problems cause the protector to open, it will

automatically reset when the motor temperature is lowered to a

safe level.
