SQ SeriesTimer - Sequencing
Connection:
The SQ Series is available with either three (SQ3) or
four (SQ4) outputs and an adjustable or xed time
delay. The time delay period is the same for each
output. This makes the SQ ideal for applications
like dust collection, automatic lubrication, air
drying, lighting displays, merchandising displays,
duty cycling, and energy management.
Operation (Sequencing):
Upon application of input voltage, Load 1 energizes for
the selected ON time delay. At the end of this ON time
delay, Load 1 de-energizes and Load 2 immediately
energizes starting another ON time delay. At the end
of this ON time delay, Load 2 de-energizes and Load 3
immediately energizes. At the end of the ON time delay
for Load 3 (Load 4 for 4 output devices), Load 1 re-
energizes and the cycle repeats. The sequential operation
continues as long as input voltage is applied.
Reset: Removing and re-applying input voltage resets the
sequence to the Load 1 ON time delay.
