function is rising-edge triggered. The logic signal should normally be at high
level. The function starts when the signal goes from low to high. If you have an
inverted logic signal, you need to connect a NPN transistor between terminal
and COM; add 10Kohm resistor to the gate for signal input.
7. Terminal 2 is reserved for customized applications.
Note for terminal 3, 4, and 5. The function of all these terminals is
accomplished by the rising phase of control signal. If the control signal is from
a momentary NO switch that is connected to the terminal, the action starts
when switch is released (from close to open). When the control signal is from
another digital device, the action starts when voltage goes from low to high.
5. How to Set the Timer and Relay Delay Time T1/T2
Press "SET" key momentarily, T1 will show up at the top display. Use Up and
Down key to set the value. Press SET again to set the T2 (only for delayed
interval or cycle mode). Press SET key confirm the setting and exit the timer
setting mode.
When adjusting the time, each time the Up or Down key is pressed, the value
will increase by one unit. But if you press and hold it, the value will continuously
increase, as the holding time increases, the speed of number increasing will
accelerate. You can use this feature for large number increment. When the
number is getting close to desired value, release the key. Then, press it
momentarily for fine setting adjustment.
6. Programming
Press SET key for 3 seconds to enter programming mode. For each parameter
setting, use up/down key to select different programming values. Press SET
key to confirm and move on to next parameter. See Figure 3 for the procedure.
For the definition of each programming value, see following section.

Definition of Programming Values
Func, timer operating function mode.
SdL (single delay): relay turns on at the beginning of relay delay time T1
(OFDL); relay turns on at the end of relay delay time T1 (ONDL). It will not
change until the timer is reset or repowered again. In Single Delay ON mode, a
special parameter for stop function, STOP will show up in the parameter menu.
For details please refer to note1 below.
dint (delayed interval): relay turns on at the end of T1 time delay then off at the
end of T2 time delay (OFDL); relay turns off at the end of T1 time delay then on
at the end of T2 time delay (ONDL). There is no repeat.
CYCL (cycle): repeat relay on and off in cycle. Relay turns on at the end of T1
time delay then off at the end of T2 time delay (OFDL); relay turns off at the
end of T1 time delay then on at the end of T2 time delay (ONDL). It will repeat
this cycle until power is off.
T1 or T2, timer range.
S: 0.01 s ~ 99.99 s.
M:S: 1 s ~ 99 m 59 s.
M: 1 m ~ 9999 m.
H:M: 1 m ~ 99 h 59 m.
tdir, timing direction.
up: counting up.
dn: counting down.
OUT, relay output mode.
OFDL (off delay): relay will be on at the start of timer and off when time reach
the set point.
ONDL (on delay): relay will stay off at the start of timer and on when time reach
the set.
RUN, timer starting run mode.
PU (power up): timer starts when powered up.
rSt (reset): timer starts when reset button is pressed and released
Note 1: Running the single delayed on mode.
When running the Single Delay On mode, depending on the applications, user
may want the relay to stay at off (initial state), or, stay on (final state) when the
operation is interrupted by stop function. Here are two examples. A) Some user
uses the timer to turn on a buzzer at the end of a process for notification
purpose. He wants to be able to disable the buzzer (change to initial state) by
simply pushing a button once he acknowledged the notification. B) Some user
wants to delay the process of turning on an oven. But sometimes, he may want
to cancel the delay (change to the final state) to start the oven by pushing the
stop key. In order to satisfy these two conflict requirements, a special
parameter for stop function, STOP will show up in the parameter menu when
both ONDL (on delay) and SDL (single delay) are selected, STOP can be
selected as 0 (default) or 1. When it is set to 0, during the delay, stop signal will
set relay to the final state (pulled-in). When it is set to 1, during the delay, stop
signal will set the relay to the initial state (dropped-out). When the time delay is
finished and relay pulled in, user can reset the relay to the initial state by
sending a stop signal, regardless of the STOP setting.
