1. Depress the desired CHANNEL button until the LED to the left of STITCH is
illuminated.
2. Depress the DIGIT button until the desired programming granularity is selected.
3. Rotate the VALUE knob until the desired STITCH value is selected.
4. Displayed values range from 00.00 to 05.00 inches in 0.05 inch increments.
The diagram below illustrates the STITCH function and its relationship with LINE, GAP
and SPIKE TIME.

Spike Time

The DPC-2 Control Unit offers a SPIKE voltage of 48VDC for a duration of from 000.1
to 025.5 milliseconds. The DPC-2 Drive output then settles to a 16VDC holding voltage
for the duration of the LINE or STITCH. This feature is provided to enable quicker Glue
Valve actuation when necessary. This parameter is only accessible from EVENT 1 of the
CHANNEL pattern program.
CAUTION: Assure the Glue Valve is designed to handle input voltages of 48VDC
for short time periods prior to employing this feature. Failure to do so may shorten
the life of the Glue Valve's solenoid or coil.
1. Depress the appropriate CHANNEL button until the LED to the left of EVENT is
illuminated. Rotate the VALUE button until 1 is displayed.
2. Depress the desired CHANNEL button until the LED to the left of SPIKE TIME
is illuminated.
3. Depress the DIGIT button until the desired programming granularity is selected.
4. Rotate the VALUE knob until the desired SPIKE TIME value is selected.
