pushing a button once he acknowledged the notification. B) Some users want
to delay the process of turning on an oven. But sometimes, they 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.
7. Wiring Examples
1) Signal controlled by external switches.
In the timer, power (120 or 240V AC) is sent to terminal 9 and 10.The external
reset (RST) and pause (PAU) switch should be momentary type. These keys
are only needed if you want to control the timer remotely. Otherwise, you can
use the front keys on the timer. These switches can also be replaced with a
control signal from computer or other control devices. The alarm speaker
used in this example is also optional. It is to show how to wire the output.
You can substitute it with any output such as a coffee grinder. The output
terminals (#6, 7 and 8) are from a "C form" internal relay. It is a dry switch that
does not provide the power by itself. In this case, the alarm is powered by the
120VAC. The external switch connected to the alarm is for disabling the sound
if needed.

8. Timing Diagrams
Following diagrams show relay output ON/OFF time under different relay
output modes and operating function modes. Please note: 1) "RUN" is set to
"rSt" in following examples, powering up to start the timer is not discussed here.
2) Timer starts counting from the moment when the reset key/switch is
released or input (TTL) signal is from low to high. 3) The timer display stops
counting as soon as stop key/switch is pressed (from high to low), but relay
output will only be triggered when stop key/switch is released (from low to high).
