LD301 – Operation and Maintenance Instruction Manual
2.6
The Display
The local indicator is able to display one or two variables, which are user-selected. When two variables
are chosen, the display will alternate between both with an interval of 3 seconds.
The liquid crystal display includes a field with 4 ½ numeric digits, a field with 5 alphanumeric digits and
an information field, as shown on Figure 2.4.
When the totalization is displayed, the most significant part appears in the unit and function field
(upper) and the least significant part in the variable field (lower). See Total Value in Section 3.
Monitoring
During normal operation, the LD301 is in the monitoring mode. In this mode, indication alternates
between the primary and the secondary variable as configured by the user. See Figure. 2.5. The
display indicates engineering units, values and parameters simultaneously with most status indicators.
The monitoring mode is interrupted when the user does complete local adjustment.
The LCD may also display errors and other messages (See table 2.1).
