4. Terminal Assignment

Figure 2. Terminal assignment of JSL-73C-24.

Details:

1). Power for the timer needs to be connected to terminal 9 and 10. The

voltage should be in the range from 90 to 260 VAC.

2). Terminals 6, 7, and 8 are for relay output. Terminals 6 and 7 are a normally-

closed (NC) contact pair. Terminals 7 and 8 are a normally-open (NO) contact

pair. Terminal 7 is their common pin. The relay is a "dry switch" that does not

provide power by itself. Please see the wiring examples in Section 9.

3).

Terminal 5 is the start terminal that has the same function as the START

key on the front panel.

Please see a note at the end this section.

4). Terminal 4 is the pause/mute terminal that function the same as the

"^/MUT" key on the front panel.

5). Terminal 3

is the reset terminal that function the same as the "V/RST" key in

the front

panel.

6). Terminal 1 is the common contact for the terminal 3/4/5. Terminal 2 is

unassigned. There are two ways to operate terminal 3, 4 and 5:

6.a) Connecting a normally open (NO) momentary push button switch between

the terminal (3, 4 or 5) to the COM (1). Please note, the function starts when

you release (or open) the button of the switch, not when you press down the

switch.

6.b)

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). 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 10 kohm resistor to the gate for signal input.

5. Operation and Parameters

In JSL-73C-24 timer, an event is defined as an action of adding an ingredient

at a specific time point during the wort boiling process. An event timer starts

from the moment that the ingredient is being added to the wort; it stops when

the wort-boiling process comes to an end. There can be multiple events during

the wort-boiling process. Each event should have a different starting time point,

but they all end at the same time, which is when the boiling process ends.

2018.10

The top display window will show the remaining time before the next event, i.e.,

when the next ingredient should be added to the wort. The lower window will

show the remaining time to the end of the wort-boiling process. The alarm relay

will pull in when a new event timer starts or when all events end.

Please see Figure 3 for a schematic diagram showing the relationship between

multiple events and the alarm relay status.

Figure 3. A schematic diagram of how the event timers and the relay work on

JSL-73C-24 timer.

A special case of the timer is to set it as a stopwatch. In this case, each

window will show a count-up timer. There is no ending point and the relay won't

pull in. The timer showed in the top window can be re-started while the timer in

the bottom window is still running. The details can be found in section 5.2.

5.1) nE, the total number of events. An event can be associated with an activity

such has adding hops or special ingredients. Each event has its own timer. nE

can be set to a number from 1 to 9. The output relay will pull in at the beginning

of all events except the first event, and at the end of the entire boiling process.

So nE is equal to the total number of times you want the buzzer to ring. For

example, if you only add hops at the very beginning of the boiling process, and
