Event is to occur. Press the ON/OFF button to select an ON or
OFF set point. Note that if momentary output has been selected
for either OUTPUT 1 or 2 only ON set points will be displayed.
Press the ENTER button to enter that set point for the selected
day. Note that the ON or OFF indicator stops flashing only after
pressing ENTER. If this set point is to occur for other days of the
week, simply press the DAY button to select the next day then
ENTER. Repeat for any additional days. Note that this allows you
to utilize one set point for any or all days of the week. A total of 20
set points are provided allowing up to 140 operations each week
(20 set points X 7 days = 140 operations). Repeat this procedure
for as many of the 20 set points as required. Attempts to enter
additional set points (beyond 20) will cause "F:UL" to appear in
the display.
TO OVERRIDE PROGRAM: Program can be overridden at any
time by selecting the MANUAL position. Program set points will
be maintained but will not operate the controlled load(s)
automatically.
TO REVIEW PROGRAM SET POINTS: Place the right selector
in the PROGRAM mode. Place the left selector in OUTPUT 1 or
OUTPUT2 mode. The display will show all zeros if there are no
set points programmed or will show the first programmed set
point and a programmed time with an ON or OFF depending on
whether the time which appears is an ON set point or an OFF set

point. Note that only ON set points will appear if the momentary
pulse feature has been selected. Pressing the ENTER button will
advance the display to the next set point in chronological order. In
other words, the next set point on Sunday or the set point on
Monday (day 2) will appear. Pressing the ENTER first button after
the last set point has been displayed will cause "E: nd" to appear
in the display. Further operation of the ENTER button will repeat
the review cycle.
TO ADD OR DELETE SET POINTS: Press the HOUR and/or
MINUTE buttons to change the time displayed to show the new
time you wish to add, then press the ENTER pushbutton. To
remove a programmed time, press the ON/OFF button two times.
When this is done, the set point displayed will be removed and
the display will show all dashes.
TO OPERATE TIMER
After programming is complete, move the selector switches to the
CLK and AUTO positions. The time switch will follow the
scheduled program but will not immediately "catch up" to the
presently programmed load condition; the time switch will "catch
up" at the next scheduled ON or OFF setpoint. If necessary, press
the ON/OFF button to turn the load on or off.
CORRECTIVE ACTION
Check battery and replace if necessary.
Replace battery within 30 days.
Reposition slide switch into detent or "wiggle" until
display is corrected. If display does not correct,
contact or return to factory for service.
Press the recessed reset switch and hold for
approximately 5 seconds.
Electrical noise interference is highly unlikely
since the electronic circuitry and the power
supply are completely isolated. The installation
of surge suppressors (metal oxide varistors-
MOVS) across terminals 3/4 & 5/6
will help to reduce electrical noise generated
at the switching contacts.
Be sure MANUAL./AUTO is in the AUTO
position.
Check program - place the OUTPUT
Selector in the OUTPUT 1 or OUTPUT 2
mode and press the ENTER button to review
all twenty Be sure power is applied to the
line terminals in order to power the load.
Note that the output contacts are isolated from
the timer power(terminals 1 and 2).
This allows the timer to switch various
loads from 24 volts through 277 volts.
