AUMA MATIC Operation Instructions
AUMA Actuators, Inc. USA
Test Run
•
Switch selector switch to local position. If local control is not supplied, refer to electrical drawing for reference
to local operation.
•
Turn control switch or operate push-button in either open or close direction.
•
If actuator fails to operate, access the interface board by removing cover and checking to see if the following
LEDS are illuminated. An LED that is on signals a fault.
V14 LED
•
Motor (line power) phasing is incorrect. Reverse U1 and W1 at field connection terminals (3Ø only) or there
may be a loss of phase. Check incoming 3Ø power.
V15 LED
•
Torque switch is tripped. Check torque switch settings. Declutch actuator and manually move to a different
position to ensure smooth operation.
V14 and V15
•
Thermal switch in motor is tripped. Feel motor, and if hot, wait until it cools down, and try operation again. If
motor continues to overheat or motor is cool and thermal switch is tripped, consult factory.
•
Optional overload relay is tripped. Standard version is set in auto reset mode. The manual reset is located
on top of the overload which can be accessed by removing the circuit board assembly.
If LED’s Are Not Illuminated, But Actuator Will Not Operate:
•
No line power.
— Check for loose connection.
— Check for correct voltage at terminals U1, V1 and W1.
— Check for correct capacitor connection (1Ø).
•
Field jumpers are not correct.
