6.1 ON DELAY
On delay functions as follows: When the timer is first powered, the delay begins with the relay
deenergized. When the delay expires, the relay energizes and stays energized until power is
removed from the timer. The unit is then ready for the next operation. The on delay function is
considered "self triggering" and the "T" (trigger) terminal is not used. If the unit is unpowered
and repowered before the delay expires, the time restarts without the relay energizing.
To call up the on delay mode, Dip Switch 2 must be turned on (it is factory set off).
This is an additional step to having set Dip Switches 3 and 4 on. This makes the unit self
triggering as it "looks" for an open circuit between "T" and "+". If Dip Switch 2 is left off, you
will get the somewhat different mode described in the next section.
