tioned threshold. The end of alarm will be entered into the Event-Log when the
button is pushed.
A low alarm threshold can never be set higher than the high alarm threshold on a
certain channel.
Set EMOs
All available low and high alarms (max. 12) can be assigned to the three logical
EMO functions, which drive the EMO relays (see p. 17). There are six different
menues, each showing low or high alarms of active channels (see p. 28) to be as-
signed. The display e.g. looks like this.
EMO 1 Low Alarms:
1N 2Y 3Y 4Y 6N
In this case low alarms from channels 2, 3, or 4 will lead to an opening of the two
relays driven by logical function EMO1 (contacts 1-2 and 3-4 will open). Low
alarms from channels 1 and 6 will have no influence on these contacts. Channel 5
is not shown, because in this case it is not activated.
Input/Output
Simulate Analog Out
For test purposes the analog outputs can be set to their max. (10 V / 1 V /
20 mA) respectively min. (0 V / 4 mA) values. With the software BMT 932 LINK
any voltage and current can be put out.
RS-232
This menu item is used to configure the serial interface. The
User
-
Baud rate
can
be set to one of the following values:
2400 Baud
4800 Baud
9600 Baud (default)
19200 Baud
38400 Baud
The setting of
Timed/Polled
decides, if the output of data on the serial interface
is done automatically in a certain time interval (Timed) or if a block of data is sent
only on request (character '?', without CR). If the operating mode is set to Timed,
a data block is sent every
Time Interval
. Minimum interval is 1 s, max. interval is
99 s. A detailed description of the serial interface can be found on page 29.
Test Scrubber
This will start the scrubber test. This test can last from 20 s to 1 minute. It dis-
plays:
