The Cycle Timer
Owners Manual
2.2 Basic Operation Example
The following example assumes that the PCT is set to the default minutes mode.
Widget Co. the worlds leading manufacturer of widgets wishes to pace the widget production process, so they
purchase a PCT with the red / yellow stack light option. A whisker switch is installed on the production line to
detect completed widgets and connected to one of the PCT CNT inputs. For this basic install, the HOLD logic
input will not be used, instead it will be the line supervisors responsibility to reset the PCT at the start of the day,
and hold the PCT during breaks using the PCT keypad.
The goal cycle time for each widget is thirty seven minutes. If a cycle time overage occurs, the stack light should
illuminate yellow for three minutes, and then red for five minutes, and then flash red.
To summarize, for the Widget Co. factory, the PCT registers need to be set as follows:
GOAL
=
0037
(GOAL cycle time is 37 minutes)
YELLOW TIME =
0003
(The stack light should be yellow for the first three minutes of overage)
RED TIME
=
0005
(The stack light should be red for the next five minutes of overage)
To set the GOAL register, press the
[F1]
key once to select the GOAL register. Use the
[+]
keys to select a goal
cycle time of 0037 minutes. Then press the
[F4]
key to apply the new GOAL setting.
To set the YELLOW TIME (
YEL
) register, press the
[F1]
key twice to select the YELLOW TIME (
YEL
) register.
Then use the
[+]
keys to select a yellow time of 0003 minutes. Then press the
[F4]
key to apply the new YELLOW
TIME (
YEL
) setting.
To set the RED TIME (
RED
) register, press the
[F1]
key three times to select the RED TIME (
RED
) register. Use
the
[+]
keys to select a red time of 0005 minutes. Then press the
[F4]
key to apply the new RED TIME (
RED
)
setting.
At the start of the day, the line supervisor should press the
[TOP]
key to reset the timer to the programmed goal
cycle time, and then press the
[RUN]
key to start the timer.
As each widget is completed, the widget triggers the whisker switch, which sends a pulse to the PCT resetting the
timer back to the programmed goal cycle time.
When the employees go on break, the line supervisor should press the
[HOLD]
key to pause the timer during the
break. When the employees return from break, the line supervisor should press the
[RUN]
key to release the
timer from hold, allowing it to resume automatically timing down.
At the end of the shift, the line supervisor should press the
[HOLD]
key to pause the timer.
