3 - Operation
3.1 - Normal Operation
DMY-2011, 2035 and 2036 Indicators have two modes of operation: normal
operation and configuration mode.
During normal operation, the Indicators monitor the two inputs and show the
totalizations, verify alarm conditions and activate the four outputs if necessary.
Configuration mode is used to select and configure all the Indicator
parameters.
The normal operation mode, in which the Indicators are 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
Changes level zero to level 1 or asks
for the password, when configured.
ACK Key
Presents the alarm outputs which
require acknowledgment to return to
normal state (*).
(*) In order to view the monitored variable, continue to press the ACK key. In
case there are no activated relays, the
No.Ac.
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 11.
