Time Delay Adjustments
Set point 1 may be equipped with time delay adjustments. Both on delay and off delay are
one turn pots.
On Delay: Length of time that set point must be satisfied before the output relay reacts.
Off Delay: Length of time that process must be below set point before the output relay reacts.
Adjustment pot fully CCW = 0 second delay
Adjustment pot fully CW = 30 second delay (approximate)

Output Relay Wiring
Before connecting the output relay to external devices, determine which failsafe mode is
best suited for the sensing level. Refer to the continuity chart to the right when connecting
to the relay terminal strip.
LO mode: When the set point is satisfied, the relay turns on. When process level falls below
the set point, the relay turns off and remains off until the set pint is once again satisfied.
HI mode: When the set point is satisfied, the relay turns off. When process level falls below
the set point, the relay turns on and remains on until set point is once again satisfied.
