5.3 PROPORTIONING TIME
Ideal Setting
The Proportional Time setting determines the cycle rate of the
output device. In the interest of long contact life, this should be the
slowest (longest setting) possible if mechanical relay output is
being used. Otherwise there is no disadvantage in using faster
settings. Refer to Figure 5-4.
