MEP-7xxx Direct-Coupled Actuators (up to 320 in-lb.) 10 Applications Guide, AN1113A Rev. D
Rotation in Wrong Direction
• For tri-state models, check the CW/CCW wiring.
• For proportional models, check the position of
the direction switch (Switch 2). See Configura -
tion on page 9 .
• For fail-safe operation, check the Fail-Safe Direc-
tion switch. See Configuration on page 9 .
Stroke Range Is Wrong
• Use and/or check position of the HMO-4536
adjustable end stop kit.
• On proportional models, check the auto-map-
ping. See Configuration on page 9 .
• Check the voltage from the controller or thermo-
stat.
Wiring Issues
• For master/slave wiring, see Master/Slave Wir -
ing on page 7 .
• Check for correct wiring for the application.
• Check the wiring at the connected devices.
• Use a voltmeter and ohmmeter to check the
terminals for expected values.
• See Tips for Connecting 24-Volt Power Applica -
tion Note (AN0604D) .
NOTE: Wiring must be adequate to avoid exces -
sive voltage drop on long runs! Allow
plenty of “cushion” in measurements. A
meter may be too slow to register tran -
sient dips or peaks during startup.
