3.7.8 A1 lat
Configuring the A1 alarm level to status latching or non-
latching.
Latching means that once the alarm level is reached, the in-
strument will trigger the alarm. It will remain in alarm status
even if the gas concentration subsequently does not meet the
alarm condition any more. To clear a latching alarm it has to be
acknowledged with OK .
In non-latching mode, the alarm status clears if the gas con-
centration does not meet the alarm condition any more.
3.7.9 A2 lat
Configuring the high level A2 alarm status to latching or non-
latching.
3.7.10 A1 ack
Configuring the A1 alarm as acknowledgeable or non-
acknowledgeable.
Acknowledgeable means that the alarm relay can be reset
before alarm conditions clear.
Non-acknowledgeable means that the alarm relay can not be
reset until the alarm conditions clear.
3.7.11 A2 ack
Configuring the A2 alarm as Acknowledgeable or Non-
acknowledgeable.
3.7.12 Explanation of combining latching and
acknowledgment of alarms
Since the concepts of latching status and acknowledgment
can be confusing, the following four combinations are offered
for clarification:
3.7.13 A1 energ on or off
Configuring the A1 alarm relay as energized.
Energized ON means that the alarm relay will change the sta-
tus in alarm condition or power off (fail safe).
3.7.14 A2 energ on or off
Configuring the A2 alarm relay as energized.
The fault relay is always energized ON (fail safe).
3.7.15 Set gas cat
Only for DSIR. Allows selecting the gas category.
The actual selection is made at the DSIR. While in this menu,
the Polytron 5000 will display gas category as it is output from
the DSIR. See Instructions for Use for DrägerSensor IR.
