Automatic Shutdown Feature
The ACT2000 has a self-protective shutdown feature. The ACT2000 will
shutdown if:
•
Any two motor winding temperatures exceed 135
°
C for ten (10)
seconds or more (130
°
C for 60 seconds )
•
The electronics temperature exceeds 115
°
C for 10 seconds or
more (100
°
C for 15 seconds )
Note: The POSITION and MOTOR CURRENT feedback signals
will both be set to 0 mA when the current to the actuator
motor is removed.
WARNING
Property Damage and Injury Hazard – If the motor windings exceed
135
°
C (130
°
C ) or the electronics exceed 115
°
C (100
°
C ), the MCE will shut down power to the motor and electronics
thereby allowing the actuator to move with load. Touching the
actuator may result in serious burn injury
