3.7 Programmable Cycle Timer (PCT) (PowerWizard 2.1)
The Programmable Cycle Timer (PCT) feature allows the operator to program times when two independent tasks, called PCT
outputs, will be activated or deactivated automatically during the week.
This is useful for cases where two or more generating sets are required to automatically share the duty of supplying a load
throughout the week. Using a programmable cycle timer, each generating set can be programmed to start and stop at pre-set
times. The cooperation of a transfer switch is required to ensure that the generating sets are not stopped on load.
Programmable Cycle Timer can also be used in cases where a standby generating set does not have access to a utility supply to
power a trickle charger. The Programmable Cycle Timer can be used to run the generating set for an hour a week to keep the
battery well charged.
The PCT feature consists of seven independent timers. Each timer has the following setpoints (setpoints shown are for PCT #1):
Day of the Week – This permits independent selection of each day (0 = Sun, 6 = Sat) that the timer will activate
•
Start Time – The time of day (in hours and minutes) that the timer will activate
•
Run For - The duration (in hours and minutes) for which the timer will be active (up to 24 hours)
•
Output #1 Active (or Inactive) – Determines the first output will be activated (or not) when this timer is active
•
Output #2 Active (or Inactive) – Determines the second output will be activated (or not) when this timer is active.
•
Output #1 is used to run the generating set. Output #2 can be used to drive relay output 8. Please see the Relay Outputs section
for more information.
3.7.1 PCT Status
The status of the PCTs can be found within the menu structure at:
MAIN MENU > CONTROL > PROG CYCLE TIMER:
The top row displays the seven PCTs (#1 to #7)
•
The middle row is for OUTPUT #1
•
The bottom row is for OUTPUT #2
•
3.7.2 Controlling The outputs
The status of each output is indicated by a 1, 0 or - in the “PROG CYCLE” column under #1 to #7”
“1” The PCT is configured and currently driving the output.
“0” The PCT is configured but not currently driving the output.
“-” The PCT has not been configured:
3.7.3 PCT example:
PCT #1 is enabled - Output 1 is not selected. Output 2 is selected but is currently inactive.
•
PCT #7 is enabled – Output 1 is selected but currently is inactive. Output 2 is not selected.
•
PCT #2 to PCT#6 are disabled. They will not activate Output 1 or Output 2.
