A beer recipe requires three different hops to be boiled for different time.

1 oz Hop A. boiling for 60 minutes.

1 oz Hop B, boiling for 30 minutes.

1 oz Hop C, boiling for 1 minute

We want the buzzer connected to the timer relay to run for 10 seconds when it is the time to add Hop B

and Hop C. The buzzer will also be on for 10 seconds when the 60 minutes boiling of hop A is finished

Set nE = 3, Ad =10, T1=60, T2=30, T3=1.

6. Terminal Assignment.

Figure 2. Back terminal assignments

Power for the timer needs to be connected to between terminal 9 and 10. The voltage should be 24V

AC/DC. No polarity needed for 24V DC power supply.

Terminal 7 and 8 are for relay output. Terminal 7 and 8 are Normally-open (NO) contacts. When the

relay is energized (or when the OUT LED is on), terminal 8 connects to terminal 7. The relay is a "dry

switch" that does not provide power by itself. Please see the wiring example below.

Terminal 5 is the start terminal that has the same function as the START key in the front panel. Terminal

4 is the mute terminal that function the same as the "^/MUT" key in the front panel. Terminal 3 is the

reset terminal that function the same as the "V/RST" key in the front panel. Terminal 1 and 2 are the

common contacts of the terminal 3/4/5. There are two ways to operate terminal 3, 4 and 5.

1) Connecting a normally open (NO) momentary push button switch between the terminal (3, 4 or 5) to

the COM (1 or 2). Please note, the function starts when you release (or open) the button of the switch,

not when you press down the switch.

2) Connecting 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 or 2). Please note, the 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.
