INTRODUCTION
This easy to program microprocessor-based time switch provides
flexible 24-hour, 7 day or full year load control. Its unique
“self-prompting” feature simplifies programming by leading you
through with flashing prompts. The LEDs on the left side flash
and indicators in the digital display light while you are
programming to identify information that needs to be entered.
SET UP information must be entered first, followed by the
PROGRAM information. PROGRAM is used to set the switching
times of the loads controlled by the time switch. Switching times
can be programmed in any combination of:
LED DISPLAY
The red LED display prompts and indicates data as it is entered in
SET UP and PROGRAM. The display indicates current time in the
RUN mode. Note the dual captions above and below the display.
RESET
Operation begins with RESET, followed by data entry with the
keypad. Pressing RESET initializes the time switch by testing and
clearing the working memory and turning off all circuit loads.
(Pressing RESET during programming will cause all data just
entered to be lost.) To clear all existing program and setup data,
press and hold the CLEAR key, then press and release RESET.
Continue to hold CLEAR until RESET appears in the display.
Fixed–Switch ON times and/or Switch OFF times that are based
on a user-selected time of day and can only be changed by
reprogramming.
RUN/SET
Pulse–The same as fixed times except the ON or OFF operation
occurs only for a short duration (1 to 127 sec.) as required for bell
ringing, signal control or the operation of latching relays.
You must have this switch in the SET position to enter, review or
clear data. When you have finished, slide the switch to RUN to
automatically save the data into non-volatile memory. If entering a
large number of set points, you may wish to periodically move the
slide switch to RUN to save your data. Return to SET after SAVE
disappears from the display and continue programming. If a power
outage occurs and you are in SET, all data not saved will be lost.
The data is permanently stored unless the memory is deliberately
erased (by pressing RESET while holding down the CLEAR key).
Data can only be modified by the user. In the event of power
failure the non-volatile memory holds the data even if the battery
backup should fail. When moving this switch to RUN, the
message SAVE briefly appears in the display. When moved to
SET the message RECALL appears briefly.
Interval–The same as Pulse times except for a longer duration
(from 1 min. minimum up to 6 days, 23 hrs., 59 min.).
Interval and Pulse also allow programming for a user selectable
override.
Astro–Based on the changing times of sunset and sunrise.
Before proceeding with programming:
• Read the instructions on pgs. 3–17
• Review the programming example on pgs. 17–19
• Complete the charts on pgs. 20–23
• Install time switch, connect ground wire as shown on pgs. 26–28
• Complete wiring by referencing examples on pgs. 29–32
While programming be sure to assign the various switch times to
the appropriate loads with the Enable switch (2 circuit models
only). When you are finished, the REV (Review) key allows you to
check the program before leaving the installation.

RUN
SET
Data entry falls into the two categories shown on the front panel:
SET UP and PROGRAM.
Next Generation

KEYPAD
SET UP
SET UP is performed once during
installation to set the internal CLOCK, ASTRO (sunrise/sunset)
times and HOLIDAY references. After entering and okaying the
ASTRO Zone, the timer will display calculated “center of time
zone” times when prompting for sunrise and sunset entries. You
may OK these, enter actual sunrise/sunset times or enter offset
times for early or late ASTRO operation. Sunrise time must be
before noon; sunset time must be after noon. Sunset must not be
within 5 hours of sunrise. Both sunrise and sunset must be
entered, even if only one is used for switching. If neither is
required, you may skip ahead by pressing HLDY or PROG keys.
(See map pp. 24–25 for details.) Holidays are entered with 2-digit
reference numbers; a chart for recording the date(s) is located on
page 22. Leap years are preset through the year 2094.
PROGRAM
PROGRAM is used for entering or
changing the switching schedule for loads wired into the time
switch. You can program circuits separately or concurrently. Each
entry affects loads whose Enable switches are in the enable
position at the time of data entry (2 circuit models only). The
time switch is shipped in a 12-hr. AM/PM mode; you can change
to 24-hr. by removing a jumper on the circuit board (see Special
Instructions). It can store a minimum of 400 events, depending
on the data type entered.
The time switch prompts you through SET UP and PROGRAM
with LEDs that advance after each entry. There are five important
points to remember:
1) The RUN/SET switch must be in the SET position to enter,
review or change data.
2) You must press “OK” after each entry, before starting the next.
3) You must press AM or PM after entering time (unless
programming Sunrise and Sunset or in 24-hour mode).
4) When in PROGRAM you must select the loads you want to
control with the Enable switches (2 circuit models only).
5) RUN/SET switch must be returned to RUN position to enable
automatic control and to save changes to data.

WKND and ALL (for all 7 days) greatly speeds the process.
The keypad keys are only functional when the RUN/SET switch is
in the SET position. Pressing keys when in the RUN position will
cause a message to scroll, explaining the function of that key. Press
any key once to stop any of the scrolling error or help messages.
AM
PM
PULSE
INTVL
ASTRO
You must press AM or PM after entering time data (except Sunrise
or Sunset) unless in 24-hr. mode. Programming fixed times for
ON and OFF events does not require PULSE, INTVL or ASTRO
keys. Multiple ONs or OFFs can be entered by pressing OK
without programming the alternate OFF or ON. Multiple OFF
times are frequently used to “sweep” off loads which have been
manually switched on after normal occupancy hours.
PULSE and INTVL (Interval) are length-of-time based options.
Maximum Pulse is 127 sec.; minimum is 1 sec. Maximum Interval
is 6 days, 23 hrs., 59 min.; minimum is 1 min. To program Pulses
or Intervals, press the PULSE or INTVL key after entering a Switch
On or Switch Off time; then enter the required duration and press
OK. Note after ON Pulses or Intervals have timed out the load
will be OFF, and after OFF Pulses or Intervals have timed out the
load will be ON, regardless of the load state prior to the start of
the Pulse or Interval. The INTVL and PULSE keys include a
temporary override function with a maximum length of 6 days, 23
hrs. and 59 min. for the interval or 127 seconds for the pulse. To
program an interval or pulse for override, select SET, enable the
circuit, press PROG, press INTVL
or PULSE (without selecting a
day), key in the interval or pulse
Next Generation

duration, then press OK. Remember INTVL or PULSE override
is initiated on demand via the keypad and is not based on a day
and time, as is normal INTVL or PULSE. To initiate an override
interval or pulse first set the RUN/SET switch to RUN and set the
switch for the desired load to Enable, then press the ON/OFF key
for the load you wish to override. The green load indicator flashes
during the interval or pulse to show override selection. At the end
of an override interval or override pulse, the load and green LED
will turn off, unless a programmed ON event has occurred during
the override time period. This allows the override interval to be
used as an “early ON” as well as a “late OFF” override after
normal hours of operation without interfering with normal
scheduled ON/OFF times.
The load will respond to any subsequent program schedules. You
may also initiate an override interval or pulse by pressing and
holding the INTVL key, then pressing the ON/OFF key for the
Enabled circuit you wish to override. This allows an override to be
started without turning off a load that is already on. This is useful
for HID lighting applications where even a brief turn off will
cause loss of lighting for several minutes. Note that override can
only be set for an interval or pulse, not both.
An override interval or pulse may be ended early only by pushing
the ON/OFF key or by a power interruption. Thus, a
programmed OFF event will not end an override interval or pulse.
At the same time, any ON or OFF events which occurred during
the override period will be in effect at the completion of the
override time period. This allows applications such as a
programmed ON time of 8:00 A.M. with a 2 hour interval
override initiation at 7:30 A.M. At 9:30 A.M., after the two hour
override, the lights will remain ON since during the override
period they were programmed to switch ON (at 8:00 A.M.).
The override pulses are precise to-the-second whereas override
interval duration is the program duration ± 30 seconds, dependent
on the instant in time when the override was initiated.
ASTRO is pressed (instead of a time entry) after selecting a day
or day group if you want switching to occur at Sunrise and/or
Sunset. If ASTRO is pressed during the “Switch On” prompt, the
timer prompts for sunset. If ASTRO is pressed during the “Switch
Off” prompt, the timer prompts for sunrise. For applications
requiring an ON event at sunrise and/or an OFF event at sunset,
press AM or PM respectively to toggle the sunrise/sunset prompts.
Interval programming may be used to extend the “Switch On”
and “Switch Off” times of ASTRO schedules. This is useful when
some circuits require differing offsets from the ASTRO ON/OFF
times that were entered during SET UP. To use this feature, enter
the earliest required ASTRO ON/OFF times during SET UP,
then use intervals of various durations to delay the ON/OFF times
as required. Specifically, use an ON interval to delay an ASTRO
turn OFF time and use an OFF interval to delay an ASTRO turn
ON time. Refer to the “Programming Examples” booklet for
detailed instructions. To program ASTRO switching with a Pulse or
Interval, press ASTRO, then PULSE or INTVL, followed by entering
a pulse or interval duration. . .all before OK is pressed.
(Clock adjustment for Daylight Savings Time (DST) is automatic;
see Special Instructions for override if DST adjustment is not
required, such as in Arizona, Hawaii and parts of Indiana. The
clock time will be adjusted by 1 hour on the first Sunday of April
and the last Sunday of October at 2:00 A.M. Due to unexpected
results, it is recommended you do not attempt programming from
12:00 midnight to 2:00 A.M. on these two days.)

categories. Press PROG to select a new day/day group when
programming of a selected day/day group is complete, or to skip
Astro and/or Holiday prompts during SET UP.
PROG
REV
SET UP
HLDY
REV (Review) allows you to check SET UP or PROGRAM data.
The holidays will review in chronological order regardless of the
order in which they were entered. CLEAR is used during Review
to delete displayed data if changes are required.
The Holiday (HLDY) feature allows the timer to follow special
schedules on selected days or periods of days, based on the date
instead of the usual 7 days of the week. Although Holiday
schedules are normally used to modify or suspend regular weekly
switching activity on actual holidays, the Holiday feature also
allows a variety of special scheduling options that are not satisfied
by the 7-day repeating schedule. See Programming Examples
supplement for details. Each holiday may be one day long or as
many days as necessary. Although each has a reference number
(1–99) that you assign, Holidays occur and review in chronological order, so the order of the reference numbers does not matter.
HLDY (Holiday) allows you to set up or review Holiday data. If a
holiday is a single day, press OK when prompted for the Stop
date, or enter the same date. Holiday scheduling applies to both
circuits of 2 circuit models. If you need to switch loads on a holiday, press PROGRAM, press HLDY, enter the reference number
1–99 for that holiday, then press OK. Program the holiday load
schedule just as you would any day or day group. If you do not
program switching times for holidays, the loads will be inactive
during the holiday period; all loads will remain in the state they
were at 11:59 P.M. on the day preceding the start of the holiday.
You may program Off events at 12:00 A.M. on holidays to
guarantee loads are off during holidays. Note the Stop date is
the last day the loads will be inactive or under special program
control. The following day the loads will resume normal
scheduling beginning at 12:00 A.M. Press PROG to exit the
holiday mode after entering the last holiday.
8
Holiday schedules and dates will remain in timer memory until
deliberately cleared. For those Holidays whose dates vary from
year to year, you must manually revise the start and stop dates (in
SET UP review) annually. Holidays may not be programmed to
end before their start date and must end by Dec. 31. During days
when the timer is following a Holiday schedule the “REF#” LED
will blink to indicate that Holiday scheduling is in effect.
The OK key must be pressed after
each complete entry; pressing it
advances you to the next data prompt. The OK key is similar to
an Enter key. After okaying a switching time, the timer automatically prompts for the alternate switching activity; i.e. Off after
On, On after Off (except after a pulse or interval entry). Pressing
the OK key without making another switching time entry alternates the On/Off prompt, allowing a succession of Off or On
events. OK is the final step after programming all steps and
enabling circuits for each switching time/type.
OK
CLEAR
COPY
HELP
CLEAR clears the last digit entered; additional digits are cleared
from the display each time CLEAR is pressed. CLEAR is also used
to clear an error code or message and return the display to the
same data that appeared before attempting to OK the data.
While in Review pressing CLEAR deletes the displayed data from
the program for the load(s) selected with Enable. Press REV to
continue Review.
COPY allows you to use the same schedule for groups of days
other than those available on the keypad (WKDYs, WKNDs or
ALL). Simply press COPY after entering a schedule for a specific
day, and at the DAY prompt key in the day you wish to copy to,
then press OK. You may also copy a day that was previously
programmed by pressing that day’s key, pressing the OK key, then
the COPY key. The display will show the selected day followed by
COPY. Now key in the day you wish to copy to and press OK to
confirm. Select and OK additional copy to days as required.
Four rules need to be followed when using COPY:
1) You cannot copy to a day that
has already been programmed.
Next Generation
9
2) You cannot copy from a day which has already been copied to.
3) You cannot copy to or from a day group.
4) The COPY feature copies the programmed schedules of all the
circuits of the copy from day to the corresponding circuits of
the copy to day regardless of the positions of the circuit Enable
switches. Individual circuit schedules may not be copied
independently (2 circuit models only).
HELP provides help messages specific to each step in SET UP and
PROGRAM. If you make an error, it will be indicated in the LED
display with an error code. (See Error Messages at the back of this
booklet, or press HELP to scroll the message across the display.)
Pressing any key or allowing the message to finish returns the
display to the condition before the error was made.
LOAD CONTROLS
There are two controls and an LED indicator
Enable
for each load. Enable/Disable activates
automatic switching of the load by the time
ON/OFF
switch, enables the override function in RUN
Disable
mode and selects circuits being programmed in
SET mode.
The ON/OFF key manually switches the load independently of
the time switch and cancels any previously initiated activity,
including PULSEs, INTVLs (Intervals) or override intervals and
override pulses. If an override interval or pulse has been
programmed, pressing the ON/OFF key of a circuit that is
Enabled will initiate that override. In order to manually switch the
load ON or OFF in this situation, you must slide the
Enable/Disable switch to Disable, press the ON/OFF key, then
return the slide switch to Enable in order to allow the time switch
to follow subsequent set points. The ON/OFF key does not
interfere with events that occur after its use. The ON/OFF keys
and LEDs will operate the loads and indicate status regardless of
the position of the RUN/SET switch.
The green LED is ON when the normally open contacts are
closed. Typical wiring methods will mean that the green LED is
ON when the load is ON. Verify this by trial and error if in
doubt. If the circuit is on due to an override interval or pulse, the
green LED will be flashing.
When timer power is restored after a power interruption, all loads
will initially be OFF. The timer then restores any enabled loads to
their programmed status as of mid-night (12:00 AM) of the
present day. For this reason, for ON periods that include
midnight, if load operation is desired immediately after power
restoration, use a redundant ON set point at each affected
midnight (12:00 AM) to guarantee predictable catch-up. Using
this same technique is recommended when Astro ON periods
include midnight.
If both loads are scheduled to turn ON (2 circuit models only),
the soft start feature will turn circuit 2 ON 15 sec. after circuit 1.
Therefore, it is generally advisable to put lighting loads on circuit
1 to hasten turn-on after power is restored. All same-scheduled
loads turn OFF simultaneously at the scheduled time. If a soft
start is not desired, program those loads using interval or pulse.
If a soft start other than the factory setting of 15 seconds is desired
press SET UP; and the date will be displayed. Then press
PULSE: SS (for Soft Start) appears in the left two displays with
3 dashes in the rightmost displays. Enter the soft start desired
by keying in a number from 1 to 127 seconds, and then press OK.
This new soft start allows you to lengthen or shorten the
15-second soft start and will affect all available circuits.
Loads that are operated by pulses (such as latching contactors)
may not be restored to the expected condition if any ON/OFF
pulses occurred during the power interruption. Consider using
fixed ON/OFF schedules in conjunction with either self-clearing
contactors or contactors adapted for “two wire control”.

INSTRUCTIONS FOR REVIEWING/REVISING DATA
REVIEW PROCEDURE
• Place the RUN/SET switch in the SET position to review.
• You must review Clock info (date, time), Astro and
Holiday dates in SET UP mode.
• You must review all load activity (Fixed times, Astro times, Pulse
operations, Interval operations and special “Holiday” load
activities) in PROGRAM mode.
• In PROGRAM, select only one load at a time using the
Enable switch (2 circuit models only). If both circuits are
enabled, you will only see switch activities common to both.
REVIEW CLOCK, CALENDAR, ASTRO DATA AND
HOLIDAY DATES
To initiate review, press SET UP (the date is displayed), then press
REV (Review). Continue to press REV for each program you wish
to review. SET UP stops after the time is displayed if no Astro
information has been entered, allowing you to enter Astro data
(Zone, Sunrise and Sunset). If Astro information has been entered,
pressing REV after reviewing the Sunset time will cause the message
“End of Review” to be displayed. Review will then automatically
advance to HOLIDAY, allowing you to select a specific holiday
reference # (01–99) for review. If you want to review all holiday
dates, press REV without selecting a reference number, and the
first holiday reference # will appear. (This will not necessarily be
reference #1 since holidays review in chronological order
beginning January 1st). Continue to press REV to walk through
the Ref # and the Start and Stop dates for each holiday until “End
of Review” is displayed. For single day holidays, Start and Stop
dates will be the same. Note that Astro sunrise and sunset times
are re-calculated daily by the timer and will differ from times
entered or reviewed on a previous date.
REVISE SET UP DATA
To revise or delete displayed information during Set Up Review,
simply press CLEAR. When reviewing Astro Sunrise and Sunset
times, you may need to press CLEAR more than one time since
each operation deletes only one digit. You can then immediately
make the revision. Be sure to press OK to enter the new data.
Note that after any revisions to the sunrise Astro time, the sunset
Astro time must be re-entered and okayed. Press REV to continue
the review.
REVIEW PROGRAM
• Be sure to select one load at a time (2 circuit models only).
Failing to do so will allow you to only review switching activities
which are common to both circuits. In other words, if both are
enabled and are both programmed to come On at 8:00 A.M.,
but Off at different times, the 8:00 A.M. On time will be the
only set point shown in Review. You must be in the
PROGRAM mode in order to review the programmed load
activities.
• In the PROGRAM mode, you can review switching activities
regardless of whether you programmed them as Fixed Times,
Astro Times, Pulse Switching or Interval Switching. Special
Holiday load activities or interval overrides are also reviewed in
Program.
REVIEW WEEK LONG SWITCHING ACTIVITIES
The normal load switching schedule is a composite of all
applicable individual day schedules, day group schedules and
copied days.The week long review feature allows this composite
schedule to be easily reviewed; by simply pressing the REV key
repeatedly, without first selecting a day, the timer will step thru all
scheduled switching times chronologically, beginning at 12:00
A.M. Sunday, or by pressing the REV key once, then pressing the
OK key, the timer will automatically step thru each scheduled
switching time, displaying each time for about 2 seconds. Press the
OK key to pause auto review. Press the OK key again to resume
auto review; or press the REV key to continue review manually.
The scheduled switching times may only be reviewed, not cleared
during week long review. Follow the steps below for individual
day/day group review if any scheduled events need to be cleared.
Next Generation

13
REVIEW INDIVIDUAL DAY, DAY GROUP, OR
COPIED ACTIVITIES
• Press PROG, then press the day key (SUN/1 through SAT/7) or
the day group key (wkDY/8, wkND/9 or ALL/0) to select the
day or day group to review.
NOTE: If you have entered data as a day group and attempt to
review any of the days individually, the message “End of Review”
will be displayed. This is because you must review data just as it
was entered, in this example, as a day group.
• Press REV, at which point the colon will disappear. Press REV
again to review the first programmed switch time. The associated
Switch On or Switch Off LED will be lit.
• Press REV again to review the next activity. If a switching time
includes a pulse or interval when you press REV, the length of
the pulse or interval will be displayed and the LED for PULSE
or INTVL will be lit. Continue to press REV until “End of
Review” is displayed. The display now prompts for a new day or
day group selection. Repeat the steps above for each circuit
individually.
• To automatically review a day or day group, press PROG, select
a day (SUN/1 thru SAT/7) or day group (wkDY/8, wkND/9 or
ALL/0), press REV, then press OK. If desired, press OK again to
pause auto review; press OK again to resume review, or press
REV to continue reviewing manually.
• If a day was copied from, you may review all days it was copied
to by selecting the copy from day, pressing OK, pressing COPY,
then pressing REV. For example, display might show 1 COPY
2 meaning that the day 1 schedule has been copied to day 2.
Push REV more times to review additional copy to days. If a day
is a copy, you may determine the day it was copied from by
selecting the day then pressing REV twice. A message will scroll
indicating the day it was copied from.
• Individual day review is not recommended for verifying
predicted operation of the timer because, since the actual
schedule is the composite of days, day groups, and copied days,
all of these would need to be reviewed, then manually combined,
to know the actual schedule for a given day. For example, if the
weekday (8) day group has scheduled activity, but no individual
weekdays (Monday thru Friday) have scheduled activity,
reviewing Monday only would immediately give the "End of
Review"message, indicating no activity, yet there will be activity
on Monday due to the weekday (8) day group schedule.
Therefore, always use the week long review feature for final
verification of the complete schedule.
NOTE: The effect of Holiday schedules cannot be seen during
week long review, so in addition to week long review, all Holidays
should also be reviewed to accurately predict the timer's operation.
REVIEW SPECIAL HOLIDAY SWITCHING
ACTIVITIES
To review special holiday switching activities, press PROG then
HLDY. Next enter the holiday reference number (01 to 99) for
the holiday activities you wish to review. Press OK, then press
REV, at which point the colon will disappear from the display.
Press REV again to display the first switching activity. Continue to
press REV while observing the LED prompts and program times
and/or Pulse and Interval times until “End of Review” is
displayed. Automatic review can also be used by pressing PROG,
HLDY, then entering the Holiday reference #, OK, REV, then
OK. If desired, press OK key to pause and resume auto review.
REVIEW OVERRIDE INTERVAL/OVERRIDE PULSE
OPERATION
• Press PROG and do not select a day or day group.
• Press INTVL. The interval duration in days, hours and minutes
as programmed will be displayed.
• Press PULSE. The pulse duration in seconds as programmed will
be displayed.
• When reviewing data, the appropriate Enable switch must be
used, one switch at a time.
REVISE PROGRAM DATA
When revising program data, make note of the following:
• RUN/SET switch must be in SET position
• Data is revised by causing it to be displayed during Review,
deleting it with the CLEAR key, and then replacing it with new
data, if desired.
Next Generation
14
15
• Program data may not be revised during week long review. You
must revise the data by reviewing the appropriate individual
day, day group, or "copied from" day.
• During automatic review, the OK key must be used to pause
the display before the displayed data can be deleted.
• After any program data is cleared, review is terminated. The
timer is now in the program mode for the selected day,
anticipating a new entry. You may make the new entry, restart
review, or return to RUN position.
• It is recommended that you repeat the "week long review" after
any revisions are complete to verify that all revisions were
implemented as desired.
To revise or delete displayed information during Program Review,
simply press CLEAR. You can then immediately make the revision
desired. Be sure to press OK to enter the new data. Press REV to
restart the review. Note that you can delete a Pulse or Interval
option from any Switch On or Switch Off time by pressing
CLEAR when the time is displayed during Review. You must reenter, then OK the Switch On or Switch Off time, even if it has
not changed. Likewise, you may add a Pulse or Interval to a
Switch On or Switch Off time by pressing CLEAR when the time
is displayed. You must re-enter the time, press PULSE or INTVL,
enter the length of Pulse or Interval, then press OK.
• To delete a holiday# (and thus its Start/Stop dates) that has
never had any scheduled On/Off times: Press SET UP, then
HLDY, then the Holiday #, then REV, then CLEAR. If the
display shows "__", the Holiday has been deleted. If "ERR 22"
shows, this Holiday has, or once had, a schedule. If so, press any
key to clear the error message then follow the steps below.
• To delete a holiday# (and thus its Start/Stop dates) when the
holiday has or once had scheduled On/Off times: Enable any
circuit, press PROG, then HLDY, then the Holiday #, then
REV. The selected Holiday # will show. Press CLEAR; the timer
will scroll a message asking if you are sure you want to delete the
Holiday schedule. After the message stops and the Holiday # is
re-displayed, press CLEAR to delete it. Now press SET UP, then
HLDY, then the Holiday #, then REV, then CLEAR. The
holiday is now completely deleted.
REVISE/DELETE HOLIDAY SCHEDULES AND
DATES
• To revise holiday Start/Stop dates: Press SET UP, then HLDY,
then the Holiday # (if known), then REV. The selected Holiday
# will show. Press REV again; the START date will show.
Pressing CLEAR will delete the START and STOP dates. Enter
the new START date, then OK. Enter the new STOP date, then
OK.
• To revise holiday schedules: Press PROG, then HLDY, then the
Holiday #. Press REV until the time that requires revision is
displayed. Press CLEAR to delete the displayed time. Enter and
OK a new time if desired.

TROUBLE SHOOTING
WARNING: Connect 24VAC 60 Hz only to 24V Timer Power
Terminals.
Problem
Solution(s)
Display Does
Not Light
• Make sure flat cable is properly plugged into the
rear of the logic module. Refer to “Re-installing
logic module” in Special Instructions. If connector will not install easily, check for bent pins.
• On multi-volt models make sure the voltage
selector jumper is correctly installed and that
matching voltage is present at timer power
terminals. On 24V models make sure 24VAC
is present at timer power terminals.
Loads Not
Switching
• Check wiring. Note the load contacts are
isolated to allow you to switch loads with a
voltage different than the timer power. You may
have forgotten to add the appropriate connections required to power the load contacts.
See wiring examples.
• Check to ensure all breakers or disconnects
have been reset.
• Make sure load switches are in Enable position
for automatic switching.
• After a power interruption all loads will be Off
and will “catch up” to the present programmed
state as of midnight of the present day. Schedules
that turn On one day, then Off one or more
days later, need a redundant switch On time at
12:00 A.M. Loads that are operated by pulses
(such as latching contactors) may not be restored
to the expected condition if any On/Off pulses
occurred during the power interruption.
Consider using fixed On/Off schedules in
conjunction with either self-clearing contactors
or contactors adapted for “two wire control”.
See “Load Controls” for details.
• Make sure the SET/RUN switch is set to RUN.

shown above. Do not mix solid and stranded wires under the same
terminal.

Problem
Load Switches
at Incorrect
Time
Solution(s)
• NOTE: Override intervals or pulses are not
ended by scheduled OFF events; they can
only be ended by timing out, power
interruptions, or by pressing the ON/OFF
key. At the termination of an override
interval or pulse, the load may be ON or
OFF. The load will remain ON only if an
ON set point has occurred during the
override interval or override pulse.
• Review SET UP to see if timer could be
following a holiday program with no
scheduled activity.
• Using the REV function, check program
times against the times you entered in the
chart.
• Review SET UP or observe the flashing
“Holiday REF #” light to see if the timer is
following a holiday schedule. Holiday dates
and schedules from the prior year do not
automatically clear or adjust. They must be
manually revised or removed annually.
• When using pulse or interval “ON” programming, the load will switch ON at the
scheduled time and OFF at that time, plus
the pulse or interval duration. For “OFF”
pulses or intervals the load will switch OFF at
the scheduled time, and ON at that time plus
the pulse or interval duration, even if the load
was not ON before the start of the “OFF”
pulse or interval.
• This timer provides an automatic 15 sec.
delay between circuits 1 and 2 when
programmed to switch at the same On time
(2 circuit models only). Use the Interval or
Pulse features to eliminate if required.
Problem
Solution(s)
NOTE: ASTRO switching times change daily
according to changing Sunrise and Sunset
Consider fixed times with this in mind, e.g. a
fixed OFF intended to end an Astro ON
would be ignored if sunset moves beyond the
fixed OFF time. The fixed event should be
scheduled to occur outside the range of the
Astro event, or an Astro Pulse should be
considered.
NOTE: Override intervals or pulses are not
ended by scheduled OFF events; they can only
be ended by timing out, power interruptions,
or by pressing the ON/OFF key. At the
termination of an override interval or pulse, the
load may be ON or OFF. The load will remain
ON only if an ON set point has occurred
during the override interval or override pulse.

Problem
Timer Ignores
Pushbuttons
Solution(s)
• Processor is “locked up”. Press and release
RESET key while holding down the
CLEAR key. Release CLEAR when “reset”
appears in display. If no improvement, remove
and restore AC power and battery, then re-try.
Difficulty in
Programming
• The two most common mistakes are forgetting
to press AM or PM after each time entry and
forgetting to select a load with the Enable
switch. You cannot program switch times
(PROGRAM) unless you select a load using the
Enable switches. Pressing the HELP key
when an error (ERR--) message appears will
explain the error and may offer
recommended action.
Override
• An interval or pulse duration must have been
Interval or Pulse previously programmed (check by pressing
Won’t Start
INTVL or PULSE key in SET mode without
selecting a day) and the circuit must be
Enabled.
Interval

During
Programming
• After any Pulse or Interval entry, the Switch
On or Switch Off LED does not alternate,
since most Pulse or Interval applications
require only ON or OFF. Press OK without a
time entry to alternate the Switch On/Off
display if required.
Problem
Some
Switching
Times Don’t
Show During
Review
Solution(s)
• All review should be done with only one
circuit enabled at a time (2 circuit models
only). If both circuits are enabled, only events
common to both will show during review. To
see all possible scheduled events, the week long
review should be used. Events programmed via
Day Group or Copy Day methods will not
show when reviewing individual days or vice
versa.
Difficulty in
• When using pulsed output for switching a
Programming/
latching relay or contactor without “selfReviewing On/ clearing” contacts, one circuit is dedicated to
Off Latching
the load Turn On Pulse and the other to the
Pulse
Turn Off Pulse (2 circuit models only). The
or
pulses are created by turning the respective
Output to
circuits On momentarily (1 to 2 sec.).
Latching
Therefore all events must be programmed and
Contactor
will review as On Pulses. The On time(s) of
Remains On
the controlled load will be shown as On Pulses
After an Off
for one circuit and the Off time(s) will review
Pulse
as On Pulses for the other circuit. Note: Using
the manual On/Off keys to switch this type of
contactor On or Off will not provide the expected
result and may cause damage to the contactor
coil. For this application an external Momentary
Pushbutton must be added for both circuits.
