Servo Alarm 10. Clear the Alarm
Servo is stuck 1. Remove the servo unit which is connected to
port #. Do not remove the servo cable.
2. Perform a servo calibration (see chapter Servo
Calibration) and check that the servo unit shaft is
rotating. (Ignore alarm SERVO # no end stop
detected)
3. Check the rotation of the interceptor shaft. The
shaft should be able to be rotated 100°. If less
than 100° something is blocking the stroke. If the
shaft can be rotated more, then the interceptor
parts must be checked.
4. See chapter Checking the shaft torque. If higher
than 12 Nm, the interceptor unit must be
checked, cleaned or re-installed. Do not proceed
until the interceptor shaft torque is below 12
Nm.
5. Mount the servo unit to the interceptor.
6. On the control panel, navigate to the calibration
menu and start calibration of the servo units.
7. Restart the system.
Servo temperature high The servo unit is very hot and has stopped. When
cooled down, remove the servo unit and check the shaft
torque.
Make sure that the servo unit has good ventilation.
Restart system when temperature normal.
Servo communication error Servo unit is connected but a communication error has
been detected. Check if the cables are damaged.
Servo high voltage Servo unit has stopped. The voltage is above 32 Volts.
Make sure that the system voltage is below 32 Volts.
Servo low voltage Servo unit has stopped. The voltage is below 11 Volts.
Make sure that the system voltage is above 11 Volts.
Servo is not connected 1. Check that the servo # is connected to the RCU
# port.
2. Check if the cable is damaged or unconnected to
port #.
Servo high current Servo unit has stopped due to electronic failure. Press
Restart System.
Servo internal error Press Restart System.
Servo rmware error Press Restart System.
Servo encoder error Servo position sensor failed. Electrical connections of
the encoder connector inside the servo unit must be
checked by an authorized Humphree Service Technician.
