DECS-400 units are delivered with the same global and setpoint access password: DECS4. When the
global and setpoint passwords are identical, the DECS-400 grants global access when the correct
password is entered. In order to permit setpoint-only access, the setpoint access password must differ
from the global access password. If the user attempts to start an edit session on a screen requiring global
access while only setpoint access is granted, the setpoint access is revoked and the user is prompted to
enter a global access password.
Passwords may be changed using BESTCOMS software (provided with the DECS-400) and a password
can contain from one to six alphanumeric characters. To provide security against unauthorized setting
changes, the passwords should be changed after commissioning. Once changed, the passwords should
be stored in a secure location. If the user-defined passwords are lost or forgotten, the default password
(DECS4) can be restored by simultaneously pressing the Edit and Reset pushbuttons during DECS-400
power-up.
Caution
Pressing the Edit and Reset pushbuttons during DECS-400 power-up
replaces all user-programmed settings with the default settings.
Restoring the default password also replaces all user-programmed settings with the default values.
Before performing this procedure, BESTCOMS software should be used to save a DECS-400 settings
file. After the default settings are loaded while restoring the default password, the settings file can be
uploaded to the DECS-400 and new passwords can be assigned.
Metering Screen
Metering screen information is displayed in five fields: metering values, alarms message, setpoint value,
setpoint—percent of range, and operating mode. The metering screen fields are illustrated in Figure 3.
Figure 3. Metering Screen Information
Metering Values
Metering values for three user-selectable parameters are displayed. Table 3 lists the metering parameters
available for display on the DECS-400 metering screen.
