7. Wiring Examples
1) Signal controlled by switches.
Power (120 or 240V AC) is sent to terminal 9 and 10.The external reset (RST)
and pause (PAU) switch should be momentary type. They are needed only 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 reset key/switch is
released or input (TTL) signal is from low to high. 3) Timer display stops
