"Programmable Cycle Timer" (PCT) feature provides the option to program the control to perform seven independently timed tasks. The output from the timers is called "PCT Outputs". The tasks will be automatically activated or deactivated during the week.The PCT feature is useful in situations that involve paralleling two or more generators. The PCT feature is useful in situations that require that the generators automatically share the duty of supplying power for a load throughout the week.The use of the PCT will allow each generator set to be programmed to start and stop at preset times. The preset times are used to meet the needs of various situations.The following scenario is one example of a PCT application. If a standby generator set does not have access to a utility supply in order to power a trickle charger, then the PCT can be preset to start and stop for 1 hour per week. The running time for the generator set will then be able to keep the generator start battery charged.
The use of a transfer switch is required in order to ensure that the generator sets are not stopped while providing power to the load.
The PCT feature consists of seven independent timers. The set points that are shown below are for "PCT 1". Each timer has the following set points:Programmable Cycle Timer 1, Activation Day of the Week - The timer set point permits independent selection of each day, Sunday through Saturday, that the timer will activate.Programmable Cycle Timer 1, Activation of the start time - The timer set point determines the time of day, in hours and minutes, that the timer will activate.Programmable Cycle Timer 1, Active Time - The timer set point determines the duration, in hours and minutes, for which the timer will be active. This set point can be set for up to 24 hours.Programmable Cycle Timer 1, Output 1 Activation Configuration - The timer set point determines whether the PCT first output will be activated when this timer is active.Programmable Cycle Timer 1, Output 2 Activation Configuration - The timer set point determines whether the PCT second output will be activated when the timer is active.Outputs
Internal Outputs
The PCT has two internal outputs. The two internal outputs must not be confused with the physical outputs of the control. The internal outputs are connected internally to the control module.In the standard configuration, "PCT Output 1" is connected to a "Remote Initiate" command. "PCT Output 2" is connected to digital selector 6 in order to control relay output 8 if there is a need.
