Special functions

Menu “7. Special functions” is used to set basic

items and expanded functions.

The menu is closed by pressing “esc” or select-

ing “Exit special functions”.

7. - Special functions

Caution

Other than the time all settings may

only be made by a specialist.

This menu contains the settings for the speed controlled output V1.

7.2. -

Signal V1

7.2.1. -

Type of Ventilator

The type of speed controlled ventilator must be entered here.

0-10V

: Speed control of ventilators by 0-10V signal.

PWM

: Speed control of ventilators by PWM signal.

7.2.2. - Ventilator

In this menu, preconfi gured profi les for various ventilators can be selected. Please

note that individual settings are still possible even when a profi le has been selected.

7.2.3. - Output Signal

The signal can become inverted here for special ventilating fans. This function is for

ventilating fans which run with 10 % / 100% smallest speed and with 0.1 V / 1% biggest

speed.

7.2.4. - 0-10V off / PWM off

7.2.5. - 0-10V on / PWM on

7.2.6. - 0-10V Max / PWM Max

7.2.7. - Show signal

Displays the set signal in text and a graphical diagram.

This signal / this voltage is put out when the ventilator is switched off (ventilators that

can detect cable break need a minimum signal).

This signal / this voltage is needed to turn the ventilator on at minimum speed / mini-

mun voltage.

This determines the output signal / the output voltage for the highest speed of the venti-

lator, that is used e.g. during purging or manual operation.
