3.0 - Operation
3.1 - Normal Operation
DMY-2030-F and DMY-2030-F Light Indicators have two modes of operation:
normal operation and configuration mode.
During normal operation, the Indicators monitor the inputs, verify alarm conditions
and activate the four outputs when necessary.
Configuration mode is used to select and configure all the Indicator parameters.
The normal operation mode, in which the Indicator is to be found most of the time,
is called level zero. In this level, the three front panel keys have the following functions:
ENTER Key
DOWN
Key
UP
Key
(*) In order to view the monitored variable, continue to press the UP key. In case
there are no activated relays with LATCHED function enabled, the No.Ack. message will
be shown.
3.2 - Configuration
In order to access configuration mode the operator is required to provide a
password which avoids a non-authorized person to change any critical parameters of the
process.
So, when ENTER is pressed within the normal operation mode, one of the
following events can happen, depending on the current configuration:
i) To access directly level 1 (GENERAL) of configuration mode, which indicates the
instrument was not configured with a password system.
ii) To display the PASS warning, indicating that the instrument is provided with a
password system (a key sequence or a value), according to Figure 7.

It changes from level zero to level 1 or asks the password,
depending on the configuration.
It changes the channel shown on the display. If the
display shows channel 1 (2), after pressing DOWN, the
display will show the measured variable from channel 2
(1).
It shows the outputs configured as alarms which need
acknowledgment to turn to normal state.
