CAUTION:
If unit has not been energized for several months, apply operating
voltage for 20 minutes prior to initial time delay.
Users should thoroughly review the technical data before selecting a product part
number. It is recommended that user also seek out the pertinent approvals files of
the agencies/laboratories and review them to ensure the product meets the
requirements for a given application.
Timing Modes
True Off-Delay – Upon application of operating voltage (min. 100ms),
output relay contacts transfer. When operating voltage is removed, the
time delay period is initiated. At the end of the delay period, output relay
contacts release. If operating voltage is reapplied prior to expiration of the
delay period, the delay will be cancelled and output relay contacts will
remain transferred.
