Tim ing Mode
Initial Dielectric Strength
Recycle tim ing – First delay period begins when input voltage is applied.
At the end of the first delay, or “off” period, the relay will operate and the
second delay, or “on” period, begins. When the second delay period
ends, the relay de-energizes. This recycling sequence will continue until in-
put voltage is removed. When input voltage is removed, the relay will de-
energize.
