Duty Cycling Program #:
Specifi es the number of the program you are currently editing. The
ECC/WCC II has 5 duty cycle programs.
Program is: ____ segments
Choose how many segments you would like to set up for the duty
cycling duration. There is a maximum of 12 segments for a duty
cycle program. When a “v” (lower case v) has been input under a
segment, the item will be off at this point for the amount of time
entered above.
of: ____ minutes each
A user entered value specifying the time interval of each segment.
You may input a value of 1 to 60 minutes in this fi eld.
Currently in segment #:
This area automatically displays which segment the duty cycling
program is currently in.
Item:
Enter Global Binary values which will be duty cycled by this
program. You may enter up to twelve items per program. Only
Binary Global values may be used in this program.
To cause equipment to be turned off when the binary globals are
turned off, use the binary globals listed on this screen to control
the schedule of equipment. For example, if you want to duty cycle
a bathroom exhaust fan, then you should control the bathroom
exhaust fan based on a time clock mode which selects its “ON”
schedule by a binary global as outlined below:
Enter a week schedule which corresponds to the
schedule of the exhaust fan. For example, if you want
the exhaust fan to be duty cycled from 8:00 am to 5:00
pm M-F and off the rest of the time, you would create
a week schedule that is “ON” from 8:00 am to 5:00 pm
M-F.
Create a binary global which is “ON” whenever the
corresponding week schedule is ON.
Input the global binary on a time clock screen as the
binary input that selects the schedule. A portion of the
time clock screen is shown below:
Contact is: CLOSED in “On” Schedule
Selected by: GB6
When GB6 is ON, the contact on the satellite controller is
closed, and the exhaust fan is on. When GB6 is OFF, the
contact opens which causes the exhaust fan to go off. The
exhaust fan will be duty-cycled along with the binary global.
