The Production Cycle Timer
Owners Manual
If you are using a 12VDC photo-eye or proximity sensor, the PCT can supply up to ½ amp of power to the sensor.
Be careful when connecting the +12VDC output to your sensor. If the sensor draws too much current, the fuse
(F1) soldered to the PCT board will blow to protect the PCT power supply.
Example logic input wiring is shown in the diagram below. Keep in mind, that for your application, you may chose
to not use some of the logic inputs. The minimum requirement is one switch or sensor that is used to activate one
of the count inputs each time a unit of production is completed. All of the other inputs (HOLD, T-RST, B-RST)
functionality can be replicated by pressing buttons on the PCT keypad.
Connecting the HOLD input to GND pauses the ACTUAL timer. Connecting the T-RST input to GND resets the
actual timer to the programmed goal cycle time. Connecting the B-RST input to GND resets the ACTUAL timer to
the programmed goal cycle time. Connecting any of the CNT inputs to GND resets the actual timer to the
programmed goal cycle time.
