Using the PCT, each genset can be programmed to start and stop at pre-set times. The PCT is capable of handling a seven-day sequence with seven independent starts happening one or more times each week. The timing of these start/stop cycles may be programmed in advance, either locally or via the service tool.
For example, if a standby set does not have access to a utility supply to power a trickle charger, the PCT can be set for an hour a week to keep the battery charged.
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 - This set point permits independent selection of each day, Sunday through Saturday, that the timer will activate. All seven days can be selected, if desired.
Programmable Cycle Timer 1, Activation Start Time - This set point determines the time of day, in hours and minutes, that the timer will activate.
Programmable Cycle Timer 1, Active Time - This 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 first output of the Programmable Cycle Timer will be activated when this timer is active and will allow the genset to start if in Auto.
Programmable Cycle Timer 1, Output 2 Activation Configuration - The second output of the Programmable Cycle Timer will be activated when this timer is active. Output 2 can be assigned to a programmable output for connection to an external device. This external device can be used to control a load bank, transfer switch, or other device.
The PCT has two internal outputs. Do not confuse the internal outputs with the physical outputs of the control. These outputs are connected internally to the control module. In the standard configuration, PCT output 1 is connected to a remote initiate command. Output 2 is customer configurable via a discrete output. This allows the operator to configure a timed relay for external connectivity.
Note: Note: The outputs of all seven timers are tied together in an "OR" fashion. This means that if any one, or more, timer is activated, then any output will activate (depending on programming).

The status of each output is indicated by a "1", "0", or "-" in the "PROG CYCLE" column under 1 through 7. Refer to Illustration 1.
The following is an explanation of the outputs as shown in Illustration 1.
- A number one (1) means that this PCT is driving that output to be true
- A number zero (0) means that this PCT is NOT driving this output true now, but, this output is programmed to be true at another time.
- A dash (-) means that this PCT is NOT programmed to activate this output.
The following is an explanation of the outputs as shown in Illustration 1.
- PCT 1 is inactive on output 1. Output 2 is not enabled and will never activate, as programmed.
- PCT 3 is active on output 1, and inactive on output 2.
- PCT 5 is NOT enabled and will never activate, as programmed, on output 1. Output 2 is active.
- PCT 2, PCT 4, PCT 6, and PCT 7 are disabled. They never activate output 1 or output 2, as programmed.
To select a specific programmable cycle timer, press the left key and right key until the desired PCT is within the selection box and then press the "OK" key.
