The Production Cycle Timer
Owners Manual
2.0 Basic Operation
Place the PCT front panel back on the box and apply power to the unit. When the PCT powers up, it first restores
GOAL, ACTUAL, and other register values from backed up memory. If the PCT’s backed up memory has expired
then all PCT registers are reset to default values.
Every PCT is operated at the factory for 24 hours before shipping the unit to the customer. Therefore it is very
likely that when the PCT starts up, the GOAL and ACTUAL values that were on the PCT when it was packed at
the factory will be restored.
The rightmost decimal point of the GOAL field flashes when the timer is running
The
[TOP]
button on the keypad resets the ACTUAL timer to the programmed goal cycle time. The
[BOT]
button
resets the ACTUAL timer to the programmed goal cycle time. The
[HOLD]
button pauses the timer. The
[RUN]
button cancels the operator request to pause the time.
The
[F1]
,
[+]
, and
[F4]
buttons are used to adjust PCT registers, which is covered in the next section.
2.1 Adjusting Register Values
The PCT has three registers that can be adjusted from the operator keypad on the front panel. GOAL TIME,
YELLOW TIME, and RED TIME. All three registers can range from 0 to 9999 minutes if the PCT is in minutes
mode, or 0 to 9999 hours if the PCT is in hours mode. (Hours mode is selected by turning switch SW2.4 ON.)
To adjust any PCT register, first use the
[F1]
key to select the register. Each press of the
[F1]
key selects the
next register for adjustment until finally rotating back to normal operating mode.
To select a register for editing, press the
[F1]
key. The first time the
[F1]
key is pressed, the GOAL TIME register
is selected for editing. The second time the
[F1]
key is pressed, the YELLOW TIME register is selected for
editing. The third time the
[F1]
key is pressed, the RED TIME register is selected for editing. The fourth time the
[F1]
key is pressed, register editing is canceled and the PCT returns to displaying the goal and actual times.
After selecting a PCT register, use the
[+]
keys to adjust the digits. The leftmost
[+]
key adjusts the leftmost digit
of the register value. The rightmost
[+]
key adjusts the rightmost digit of the register value.
Once the desired new register value is displayed on the PCT, press the
[F4]
key to enter the adjustment and
return the PCT to normal operating mode. If the
[F4]
key is not pressed, the adjustment will not take effect.
There is a timeout on adjusting PCT registers, if no
[+]
keys are pressed for 10 seconds, the PCT will
automatically cancel the adjustment and return to normal operating mode and the register will remain unchanged.
