Percentage Timer Relay Output

OPERATION

When voltage is applied to the input, the internal relay energizes and

the ON time(T1) begins. Upon completion of the ON time, the relay

de-energizes and the OFF time (T2) begins. At the completion of the

OFF time, one ON/OFF cycle is completed. This cycling action continues

until voltage is removed from the input. The ON/OFF ratio is adjustable

from 0 to 100 percent of time base. 0% is OFF; 100% is ON. Reset is

accomplished by interrupting the input voltage.
