Example 3

Intention:

You want to trigger the pre-programmed 3-tone gong signal (factory-preset G21) by an external key.

The functioning of the 4-tone gong signal has to be maintained.

Summary

1. To include the reproduction of the 3-tone gong signal in the existing configuration, you have to

program a suitable control sequence (e. g. S05). The sequence is also about to trigger an external

control-lamp for the time, the gong signal gets reproduced. This example utilizes the identical relay

contact 4 of the port A (=A4) that is already in use for the 4-tone signal.

2. The unused input of the pre-gong signal (e.g. B4) has been connected to the start-key (page 30). It

has to be programmed in the trigger menu to activate the above sequence (S05).

Step By Step Programming

Enter the password for the user level 3 on the display,

using the four cursor keys (page 10) and confirm your

action with the "ok"-button.

If you have entered the correct password,

the display briefly shows this message and

then returns to the main menu.

Creating a procedure, the 3-tone gong signal G21 has to be included into a sequence (page 23). The

sequence-preset S 25 is chosen as the root-preset for further programming (page 39).

After pressing the indicated cursor key five times, the

sequence menu appears on the display. Confirm your

selection by pressing the "ok"-button.

Pressing the soft key "ok" once again shows a menu that

lets you select a sequence-preset.

The blinking cursor is positioned at the "0" in the

display's bottom line.

Press the indicated cursor key repeatedly until "S 25" is

selected. Press the soft key "yes" to load the sequence

preset S 25 (root-sequence).

Since the procedure has to be changed in accordance to

the new requirements, you have to select its listing by

pressing the "ok" key.

The first step (step 1) of the S 25 listing is displayed,

which stays unchanged (relay contact A1 can be utilized

to turn the system's power on).

Pressing the indicated cursor key displays step 2 which

stays unchanged (release-input A1 of the electro

acoustic system ready?).

Pressing the indicated cursor key displays step 3 which

stays unchanged (relay contact B4 for music off).
