ORM SeriesTimer - Delay-on-Make
Connection:
L1 N/L2
The ORM Series features open PC board
construction for reduced cost. It has isolated,
10A, DPDT relay contacts and all connections are
0.25 in (6.35 mm) male quick connect terminals.
The time delay may be ordered as factory xed,
onboard knob, or external adjustment. Time delays
from 0.05 - 300 seconds.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until voltage is removed.
Reset: Removing input voltage resets the time delay
and output.
For more information see:
Appendix A, pages 156-164 for function descriptions
and diagrams.
Appendix B, page 165, Figure 11 for dimensional drawing.
