4.3 Setting the System Configuration
The configuration menus can be entered from normal mode by pressing the MENU key. While in configuration mode, the user can review
all configuration parameters to check the current operating conditions. As an aid when configuring the control panel, the first entry in the
top menu summarizes the number of sensors and relays that the panel is currently recognizing. Be sure that the 4-20mA output on each
sensor is set to "On".
The MENU key is also used to return to a higher-level menu and finally exit the configuration menus back to normal mode. When exiting
from the menu system to normal mode, if any configuration changes have been made, the panel will ask whether changes are to be
saved.
Pressing the zero (0) key at this point will cancel all changes except time and day of week. Pressing the one (1) will save all changes to
memory, and the changes will then become effective in controlling the ventilation system.
While the DVP-120 is in the configuration mode, alarm and ventilation control functions continue in the background with the previously
set configuration values. In particular, if an alarm condition is detected, the alarm lamp, the buzzer, the horn and the strobe will operate
as configured but the LCD will not display the detailed information. The HUSH key can be used to silence any alarm, warning or trouble
indicators without having to exit the configuration mode. If the MENU key is used to exit the configuration mode before using the HUSH
key, the LCD will display the cause of the audible indicator.
The numeric keys are used to change the particular parameter displayed. The underlined character, or space, on each display, indicates
what will be changed by the digit keys.
The left and right cursor keys will enter the particular submenu and scroll through the items of the same type where appropriate, e.g.
enter the Configure Sensors submenu and scroll through the parameter lists for the existing sensors.
The up cursor key scrolls through the menu entries in the order listed here, while the down cursor key scrolls in the reverse order.
Changing the configuration parameters requires the entry of a password before changes can be made. The default password is 1234.
See Figure 3-21 for an example of the password prompt.
In many cases, the parameter is entered as a string of digits, but some parameters are selected by pressing a single key, e.g. pressing
1 selects Monday, 2 selects Tuesday, etc.
