Dancer Applications
Symptom
No output.
Output full on or full
off.
Output does not
increase during
stop time.
Dancer arm hunting
during stopping.
Remote meter not
working.
Possible Cause
No DC power.
Fuse blown.
Output wires open circuit.
Jumper not installed
between 20 and 21.
DFP or DFP-2 sensor not
wired properly or wires
shorted.
Dancer not calibrated.
DFC-A in PID mode and
RUN/STOP switch is not
wired properly.
RUN/STOP switch not
connected or not wired
properly.
STOP MULTiplier
potentiometer not set
properly.
STOP MULTiplier is being
used.
Incorrect type of meter.
Meter wires shorted or
open.
Solution or Diagnostic
Verify incoming power is the correct
voltage.
Output wires shorted together or
shorted to ground.
Verify output voltage or current at the
receiving device.
Install jumper between terminals 20
and 21.
Verify DFP or DFP-2 sensor is wired
properly and follow the calibration
procedure in section 5.3.
Voltage between terminals 24 and 26
should be 10 vdc.
Voltage between terminals 25 and 26
should change as the DFP or DFP-2
is moved through its travel.
Follow the calibration procedure in
section 5.3.
Verify RUN/STOP switch wiring. PID
mode needs a RUN/STOP switch for
proper operation.
Verify RUN/STOP switch wiring.
Turn STOP MULT potentiometer
clockwise to increase the stopping
torque.
Turn STOP MULT potentiometer
counter clockwise to decrease the
hunting during stopping.
Meter should be a current meter with
1 ma full scale and no more than
500 ohm resistance.
Disconnect meter wiring at the DFC-
A and check for proper meter
resistance between the wires.
