Connect a DC logic signal (TTL or CMOS or voltage in the range from 3 to
30 VDC) between the terminal (3, 4 or 5) to the COM (1). Please note, the
function is rising-edge triggered. The logic signal should normally be at a 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 the
terminal and COM; add 10Kohm resistor to the gate for signal input.
See
Figure 6 for details.
7. Terminal 2 is reserved for customized applications.
Note for terminal 3, 4, and 5.
These terminals are activated by the rising
phase of control signal. If the control signal is from a NO switch that is
connected to the terminal, the action starts when the switch is released (from
close to open). When the control signal is received from an external device, the
action starts as the voltage goes from low to high.
5. How to Set the Timer and Relay Delay Time T1/T2
Press “SET” key momentarily,
and 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 to 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 key is held, 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. Press it momentarily for fine
setting adjustment.

Press the SET key for 3 seconds to enter programming mode. To reach
individual parameter settings, use up/down key to select different programming
values. Press the 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 Parameters
Func, timer operating function mode.
Available options are:
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.
Available options are:
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.
H:
1 h ~ 9999 h.
D:H:
1 h ~ 99 d 23h.
tdir, timing direction.
Available options are:
up
: counting up.
dn
: counting down.
PoM, power-on memory setting.
Available options are:
After a loss of power, this timer can be set to either reset when power is
restored, or continue running from the point of power outage.
ON
: After a loss of power, this unit will continue running from the point of power
outage when power is restored.
OFF
: After a loss of power, this unit will be reset when power is restored.
OUT, relay output mode.
Available options are:
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.
Available options are:
PU
(power up): When timer is powered up, timer will start counting.
rSt
(reset): When reset button is pressed and released, timer will start counting.
Note 1
: Running the single delayed on mode.
When running the Single Delay On mode, depending on the applications, users
may want the relay to stay at off (initial state), or stay on (final state) when the
operation is interrupted by stop function. 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
