Control levels

Note!

Any changes in the configuration level (PA and CO levels) may cause errors in the sys-

tem. Therefore, they must be only performed by the specialist!

Fig. 1 shows the level structure in the

TROVIS 5177 Ventilation Controller. It also

shows the operating steps that need to be

taken to access each individual level. The con-

troller contains two main levels: the operat-

ing level and the configuration level. Use the

changeover key (C) to switch between the lev-

els. The operating level contains the info lev-

els, in addition to this, when switched to the

manual mode, a manual level is also accessi-

ble. The configuration level contains the

parameter levels, the system code number

level and the configuration levels. The info,

parameter and configuration levels are

assigned to an index from 1 to 9 which is the

same in all three levels. In this way, specifica-

tions concerning the heating coil are always

termed InF1, PA1 und Co1 (index 1) accord-

ing to the level. All other indices are summa-

rized in the table opposite.

Usually, the ventilation controller is in the

operating level and the time appears on the

display. In Fig. 1, for example, 10:24 is

indicated on the display. Apart from the

time, symbols to represent the operating

mode and operating status as well as the sys-

tem represented symbolically appear on the

display. Refer to page 147 for a summary

of the major symbols.

A bar graph appears on bottom right-hand

corner of the display, showing roughly the

control signals Y1, Y2 and Y3. This bar

graph is shown in the operating level.

Note: Two minutes after the last entry, the

controller returns automatically from the

configuration level back to the operating

level.
