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”.
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
for each load. Enable/Disable activates
automatic switching of the load by the time
switch, enables the override function in RUN
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.
