6.6 Manual Analyzer Override
The Vertex M Analyzer is equipped with a “Manual
Override” button (
Figure 6-1 ) in the event the
communications to the Vertex M Data Acquisition (DAq)
computer halts. This button activates only when the
communications has completely ceased.

Location
There are cases where the DAq appears to be “frozen”
or “locked-up” (no response from the keyboard and/or
any user invoked actions after a few moments) when
in reality this is not the case. Events that could cause
these symptoms include AC power surges or sags
and improper shut-downs of the DAq that result in file
corruption. As a result, future attempts to access these
files can slow down the response of the DAq. To confirm
a non-responsive DAq as opposed to frozen/locked-up,
check the clock located in the upper right hand corner
of the Vertex M HMI window (shown in
Figure 6-2 ). If
the clock is still advancing, then the DAq CPU is not
frozen/locked-up and your local Authorized Service
Center needs to be contacted for assistance.

On occasions, there may be the need to install a new
Chemcassette
®
to continue monitoring your facility, or
to reset alarms or faults. If the DAq is not responding,
these tasks can be performed using the “Manual
Override” button. An extra step may be required to
“force” activation of the “Manual Override” button under
the above mentioned conditions if the DAq computer
is still communicating with the analyzers. The following
instructions will instruct you on how to accomplish this
task:
Note:
Performing this task will generate Maintenance Fault
