If the jumper wire shown in each
diagram is replaced by a resistor,
delay time will be added to that
which is produced by an internal
fixed resistor on fixed time models
(code F) or any setting on screwdriver
adjustable models. See timing resistance
chart above. Relay will not operate without
a jumper or resistor. Also see note 1.
