Revised 1/99 TPC-2 TIMER Manual #50-05
Spike Time
The TPC-2 Control Unit offers a SPIKE voltage of 48VDC for a duration of from 000.1
to 025.5 milliseconds. The TPC-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.
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 desired CHANNEL button until the LED to the left of SPIKE TIME is
illuminated.
2. Depress the DIGIT button the necessary number of times until the desired
programming granularity is selected (the desired place-holder digit is flashing).
3. Rotate the VALUE knob until the desired SPIKE TIME value is selected.
4. Displayed values range from 000.1 to 025.5 These numbers are expressed in
milliseconds.
NOTE: SPIKE TIME is accessible only when EVENT1 is selected for each CHANNEL.
All other EVENTs (2 through 4) in that CHANNEL’s program use the same SPIKE
TIME value.
Clearing Programmed Information
The TPC-2 Control Unit offers a simple means of reverting all program parameters (i.e.
all SYSTEM parameters and all CHANNEL parameters in all Programs), with the
exception of SPIKE TIME, TRIG MODE and TIME RANGE, to their factory pre-set
values.
1. Turn off the input power to the TPC-2 Control Unit by toggling the power switch in the
lower left corner of the Display Panel to the “O” (OFF) position.
2. Simultaneously depress the SYSTEM and DIGIT buttons while toggling the TPC-2
power switch to the “
” (ON) position. All parameters are now reset to factory pre-set
values.
