ACM 150
Database Maintenance
As the ACM 150 monitor is normally running in a 24/7 environment, it will pile up
huge amounts of data in the database. After several months of operation, this may
lead to a slower overall system performance because it takes more and more time
to retrieve data from the database. To effectively reduce the database size, the
button "Offline Database Maintenance" may be clicked. This password-protected
maintenance operation will take less than a minute and will:
•
bring the ACM 150 monitor into "Manual Mode".
•
delete all data from the table "Logged Gas Scan Results".
•
put the ACM 150 monitor back into "Automatic Mode", restarting the normal scan
sequence.
CAUTION!
This operation deletes all stored gas concentrations on the ACM 150 monitor.
After triggering this, there will be no trend data for the period before the
operation. However, there will still be all logged peak and average gas
concentrations in the Time-Weighted Average files. This operation will not
delete any alarm or service events.
Manual mode operations

access various manual tests. Each test requires login access.
CAUTION!
Placing the ACM150 in Manual Mode or Front Panel Mode will place all flow
control in the hands of the operator. If the vacuum pump is operating to provide
vacuum, the Operator must ensure that either sufficient flow reaches the pump
to prevent overheating, or that the pump is turned off to prevent damage.
Mode control
Mode Control places the ACM 150 monitor into the 'Manual Control' mode, as shown

1. You can proceed to any of the following 4 test modes and perform the tests
either from the ACM 150 monitor touchscreen or from a remote computer.
2. If you are at the ACM 150 monitor, it may be easier to run tests from the local
control panels. To do so, select 'Switch to Frontpanel Mode' and perform the
tests from these control panels:
•
Sample Valve Control Panel (refer to
•
Cycle Valve Control Panel (refer to

inactive.
