C. HIDDEN PARAMETERS
The parameters in this section are separated from the Direct Access parameters because they are
infrequently changed and should not be changed by the operator. The parameters are listed in:
TABLE 4-2
To enable access to Hidden Parameters, follow the sequence described below.
1. Turn power off, if it is on, then wait until the display goes blank.
2. Press the
key and the
key simultaneously. Keep pressed then,
3. Turn power on. A series of "***" will appear on the display. They will slowly dissapear.
4. Release the keys then press the
key before all the stars dissapear.
5. Press the
key repeatedly, until the first hidden parameter group (****SPEEDS) is dis
played. Note that 4 stars (*) as described in section "A".
6. Parameters may then be changed by following the procedure described under
DIRECT ACCESS PARAMETERS (Page 4-1).

RPM
RPM
TRIM/POS
MAXIMUM
Machine speed during the position trim cycle.
If *** Tgl switch "position" is set to w/ramp the "trm/pos"
speed affects the slope of the ramp. If "no ramp" is
selected, position speed is constant and can be changed
by the "trim/pos" parameter.
Maximum sewing machine speed. The speed cannot go
higher than 3500 times the pulley ratio.

****MISCELLANEOUS
HYSTERESIS
PF DUTY
The amount the pedal has to be moved when going from
one direction to the other before the speed changes.
Average voltage applied to Pr. Ft. solenoid. The voltage
should be high enough to keep the solenoid energized
without overheating.

Direction of motor rotation viewed from pulley.
Select position with ramp or position at constant speed.
Maximum speed until eye is uncovered.
Set to enable only on machine with trimmer safety sw. If
enabled, machine will not run unless safety switch is
properly connected.
Defines operation of safety switch. If "CLS" machine
starts only when the switch is closed. If "OPN" machine
starts only when the switch is open.
