Representation of status registers for menu items 4, 5, 6 and 8
UNIGAS 300 features three status registers:
•
status register 1; calibration-relevant alarms
•
status register 2; operation-relevant statuses
•
status register 3; other alarms and warnings
A status register contains a maximum of 16 alarms or warnings.
A status is due to an event or condition. A status due to a condition will be reset when the condition ends. A
status due to an event will be reset at the next 5 minutes transition after registration in the loggers.
In menu item 8 the state of the alarms of status register 1 is retained until a manual reset has taken place. The
alarms can only be reset, when the cause of the alarm no longer exists. By means of UNITOOL the reset
action can be protected, see chapter 10, register C.93.14.
The state of the status registers is shown on the display as text messages in menus 8-1, 8-2 and 8-3.
In the presentation of interval data and data of the day and month loggers, menu items 4, 5 and 6, the three
status registers are shown as three hexadecimal numbers of four characters:
St : 1

In the UNITOOL software the state (condition) of the status registers is represented in a comparable way, but
pre leading 0 are not shown.
On the pages that follow, the three status registers are explained in more detail. The tables successively
represent:
•
the name with which a status message is shown in menu items 8-1, 8-2 and 8-3
•
the classification of alarms or warnings for the presentation of St for menu items 4, 5 and 6
•
the values of the presentation of St that belong to an alarm or warning
•
the nature of the alarm or warning: C= condition (state) and E= event
•
bit numbering as shown in UNITOOL when reading the status log book, see below
•
description of the properties of the alarm or warning.
To determine the status on the basis of the presentation in menu items 4, 5 and 6, the value of a character is
searched for in the three tables for each status register and character of that status register. Attention: A
character can refer to more than one status messages.
Remark: Presentation of the status message of the status log book when reading by means of UNITOOL.
For each status bit change the status log book makes a report with time stamp. The report is presented by two
numbers and the nature of the report. The presentation is in accordance with VDEW:
•
the first number indicates the status register 1, 2 or 3
•
the second number indicates the bit number in that status register, where bits 0 – 9 are indicated with
0 – 9 and bits 10 – 15 are indicated with A – E
•
VDEW status: 0200 indicates that it involves an event, 0400 the beginning of a state and 0800 the end
of a state.
