MODE 0 LATCH OUTPUTS AT PRESETS, MANUAL RESET TO ZERO, TIME
STOPS AT PRESET 2 (INSTANTANEOUS & TIME DELAY
CONTACT, TIME UP)
In this mode, as the unit times up from zero, output 1 will latch
on when preset 1 is reached and output 2 will latch on when preset
2 is reached. The unit will stop timing when preset 2 is reached.
This mode also has an input tracking feature (INSTANTANEOUS CONTACT)
where if preset 1 is set to zero, output 1 will turn on when the input is activated,
and it will turn off when the input is deactivated. (Output 2 is the TIME
DELAY CONTACT.) When a manual reset✰occurs, the unit will Reset to
Zero and the outputs, if latched on, will unlatch.
To use as an INSTANTANEOUS AND TIME DELAY CONTACT timer,
set preset 1 value to zero and set preset 2 value to the desired delay value.
When “RUN” is at a low level, time will increment and output 1 will be
activated. Output 2 (TIME DELAY CONTACT) will activate when preset 2 is
reached. To recycle use 1) reset, or 2) set the power-up reset switch to enable,
then remove and reapply input power.
MODE 1 LATCH OUTPUTS AT PRESETS, MANUAL RESET TO ZERO, TIME
CONTINUES AT PRESET 2 (INSTANTANEOUS & TIME DELAY
CONTACT, TIME UP)
In this mode, as the unit times up from zero, output 1 will latch
on when preset 1 is reached, and output 2 will latch on when preset
2 is reached. Time will continue to accumulate after preset 2 is
reached. This mode also has a input tracking feature (INSTANTANEOUS
CONTACT) where if preset 1 is set to zero, output 1 will turn on when the
input is activated, and it will turn off when the input is deactivated. (Output 2
is the TIME DELAY CONTACT.) When manual reset✰occurs, the unit will
Reset to Zero, and the outputs, if latched on, will unlatch.
To use as an INSTANTANEOUS AND TIME DELAY CONTACT timer,
follow the description under Mode 0.
MODE 2 OUTPUT 1 TURN OFF AT PRESET 2, LATCH OUTPUT 2 AT PRESET
2, MANUAL RESET TO ZERO, TIME STOPS AT PRESET 2
(INTERVAL, TIME UP)
In this mode, as the unit times up from zero, output 1 will turn
on when preset 1 is reached. When preset 2 is reached, output 2 will
turn on and output 1 will turn off. Output 2 will remain latched on
until a manual reset occurs, and the unit will stop timing when preset 2 is
reached. This mode also has an input tracking feature where if preset 1 is set to
zero, output 1 will turn on when the input is activated, and it will turn off when
the input is deactivated. (After preset 2 is reached, output 1 will turn off and
stay off, regardless of the input condition, until a manual reset✰occurs.) When
a manual reset✰occurs, the unit will Reset to Zero and the outputs, if latched
on, will unlatch.
To use as an INTERVAL timer, set preset 1 value to zero and set preset 2
value to the desired delay value. When “RUN” is at a low level, time will
increment and output 1 will be activated. Output 1 will deactivate (regardless
of the input condition) when preset 2 (TIME DELAY VALUE) is reached. To
recycle use 1) reset, or 2) set the power-up reset switch to enable, then remove
and reapply input power.
MODE 3 OUTPUT 1 TURN OFF AT PRESET 2, LATCH OUTPUT 2 AT PRESET
2, MANUAL RESET TO ZERO, TIME CONTINUES AT PRESET 2
(INTERVAL, TIME UP)
In this mode, as the unit times up from zero, output 1 will turn
on when preset 1 is reached. When preset 2 is reached, output 2 will
turn on and output 1 will turn off. Output 2 will remain latched on
until a manual reset occurs, and the unit will continue to accumulate time after
preset 2 is reached. This mode also has an input tracking feature where if preset
1 is set to zero, output 1 will turn on when the input is activated, and it will turn
off when the input is deactivated. (After preset 2 is reached, output 1 will turn
off and stay off, regardless of the input condition, until a manual reset occurs.)
When manual reset✰occurs, the unit will Reset to Zero, and the outputs, if
latched on, will unlatch.
To use as an INTERVAL timer, follow the description under Mode 2
MODE 4 TIMED OUTPUTS AT PRESETS, MANUAL RESET TO ZERO, TIME
STOPS AT PRESET 2
In this mode, as the unit times up from zero, output 1 will turn
on when preset 1 is reached, and output 2 will turn on when preset
2 is reached. The outputs will turn off after their respective
programmed time values have occurred. Also, the unit will stop timing when
preset 2 is reached. When a manual reset✰occurs, the unit will Reset to Zero.
Manual reset✰will terminate the timed output, if the outputs are still turned on.
MODE 5 TIMED OUTPUTS AT PRESETS, AUTOMATIC RESET TO ZERO
AFTER TIMED OUTPUT 2 ✝(TWO LOBE OFF/ON RECYCLING,
TIME UP)
In this mode, as the unit times up from zero, output 1 will turn
on when preset 1 is reached and output 2 will turn on when preset
2 is reached. The outputs will turn off after their respective
programmed time values have occurred. Also at the end of timed output 2, the
unit will automatically Reset to Zero and start the cycle over. Manual reset✰
will turn off both outputs, if turned on, and reset the time to zero.
When used as an OFF/ON RECYCLING timer, the total cycle time is equal
to the sum of the preset 2 value and the programmed timed output 2 value. The
first lobe of the cycle will use output 1. The first ON delay value is equal to the
programmed timed output 1 value.✝✝ The second lobe of the cycle will use
output 2. The second ON delay is equal to the programmed timed output 2
value.✝✝ When “RUN” is at a low level, time will increment. Output 1 (first
ON delay) will activate when preset 1 is reached, and output 2 (second ON
delay) will activate when preset 2 is reached. The unit will recycle at the end
of timed output 2.
MODE 6 TIMED OUTPUTS AT PRESETS, AUTOMATIC RESET TO ZERO AT
PRESET 2 ✝(TWO LOBE OFF/ON RECYCLING, TIME UP)
In this mode, as the unit times up from zero, output 1 will turn
on when preset 1 is reached and output 2 will turn on when preset
2 is reached. The outputs will turn off after their respective
programmed time values have occurred. Also when preset 2 is reached, the unit
will automatically reset the time to zero and start the cycle over. (Output 2 will
remain on until its time value has occurred.) Manual reset✰will turn off both
outputs, if still turned on, and reset the time to zero.
When used as an OFF/ON RECYCLING timer, the total cycle time is equal
to the preset 2 value. The first lobe of the cycle will use output 1. The first ON
delay is equal to the programmed timed output 1 value.✝✝ The second lobe of
the cycle will use output 2. The second ON delay is equal to the programmed
timed output 2 value.✝✝ When “RUN” is at a low level, time will increment.
Output 1 (first ON delay) will activate when preset 1 is reached, and output 2
(second ON delay) will activate when preset 2 is reached. The unit will recycle
at the beginning of timed output 2.
MODE 7 OUTPUT 1 TURN OFF AT PRESET 2, TIMED OUTPUT 2 AT PRESET
2, AUTOMATIC RESET TO ZERO AFTER TIMED OUTPUT 2 ✝
(INSTANTANEOUS & TWO LOBE OFF/ON RECYCLING, TIME UP)
In this mode, as the unit times up from zero, output 1 will turn
on when preset 1 is reached. When preset 2 is reached, output 2 will
turn on and output 1 will turn off. Output 2 will turn off after its
programmed time value has occurred. At the end of timed output 2, the unit
will automatically Reset to Zero and start the cycle over. This mode also has an
input tracking feature (INSTANTANEOUS CONTACT) where if preset 1 is set
to zero, output 1 will turn on when the input is activated, and off when the input
is deactivated. (After preset 2 is reached, output 1 will turn off and stay off,
regardless of the input condition until a reset occurs.) Manual reset✰will turn
off both outputs, if turned on, and reset the time to zero.
When used as an OFF/ON RECYCLING timer, the total cycle time is equal
to the sum of the preset 2 value and the programmed timed output 2 value. The
first lobe of the cycle will use output 1. The first ON delay is equal to the
difference between preset 1 and preset 2 values (this is because output 1 will
turn off at preset 2). The second lobe of the cycle will use output 2. The second
ON delay is equal to the programmed timed output 2 value.✝✝ When “RUN” is
at a low level, time will increment. Output 1 (first ON delay) will activate when
preset 1 is reached, and output 2 (second ON delay) will activate when preset
2 is reached (output 1 will deactivate when preset 2 is reached). The unit will
recycle at the end of timed output 2.
✰- Manual reset, either by front panel reset (if enabled) or remote reset, is
always active, and will override any condition or state of the timer.
✝- The timed output value must be less than the value required to time from
the reset condition to the preset point. Otherwise, the output will appear to
be latched on.
✝✝ - The maximum ON delay is 99.99 seconds.
