Chapter C - SERVICE MODE
n 62
This service mode displays the horizontal position of the foot control pedal. The display range
is from -255 to 255. The display must be 0 (zero) when the pedal is in the middle (rest posi-
tion). Moving the pedal sideways ±6mm should still produce 0 (zero) on the display. Bringing
the pedal to about 5mm from the left side extreme (mechanical stop) should show -255 on the
display. Likewise bringing the pedal 5 mm from the right extreme should show 255 on the dis-
play. Pushing the pedal down during this test should not change the display more than ± 15%.
Perform the foot control calibration as described in 2.6 "Calibrating foot control" on page H-15
if the above described cannot be achieved.
n 63
This service mode displays the vertical position of the foot control pedal. The display range is
-100 to 100. Pushing the pedal down changes the display sign (positive/negative). Both
extremes (pedal idle / pedal pushed down) should be symmetrical within 20%. Typical idle
value is 50 to 80. Perform the foot control calibration as described in 2.6 "Calibrating foot con-
trol" on page H-15 if the above described cannot be achieved.
n 64
This service mode shows the direct signal of pedal position (left side sensor). When the pedal
is in the middle (rest) position the number should be in the range 3000 to 7000. The sensor
plate under the foot control PCB is too far from the PCB if the number is smaller than 3000.
During this condition it could be impossible to properly calibrate the foot control. The proper
distance between the plate and the bottom surface of the PCB is 0.5 mm (± 0.1 mm). Under
no circumstances should the plate be allowed to come in contact with the PCB.
n 65
This service mode shows the direct signal of pedal position (right side sensor). See explana-
tion above for details.
n.66
This service mode can be used to select the foot control pedal instrument control mode.
Mode 0 is normal pedal operation (default). The instruments are controlled with horizontal
movement of the pedal.
In mode 1 the instruments are controlled with vertical movement of the pedal. Instrument
spray is switched on and off by moving the pedal to the left. The manual chip blow is activated
by moving the pedal to the right. Other functions work normally. Note that this feature is
recommended to be used only with a new type foot control pedal (from foot control serial
number 813542).
In mode 2 the instruments are controlled with horizontal movement of the pedal, and the
reversing of the micromotor rotation is done with foot control as follows. To operate the
micromotor normally (in a clockwise direction) push the pedal to the left. To reverse the
direction of rotation push the pedal to the right. Note, that the reverse rotation of micromotor
key does not function in this mode.
