WCC3.EXE SCREEN DESCRIPTIONS
Duty Cycle Screen
NOTE: 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:
1. 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.
2. Create a binary global which is “ON” whenever the
corresponding week schedule is ON.
3. 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.
