8.6 Function 4.5 – Load Chemcassette
®
/Filter Change
Purpose
Use the load Chemcassette
®
function to reset the tape counter when
loading a new Chemcassette
®
.
To ensure system integrity, a new Chemcassette
®
should be replaced
before the old Chemcassette
®
runs out of tape.
The CM4 automatically keeps track of Chemcassette
®
tape usage, and
reports a “Low Tape” fault when the Chemcassette
®
is nearing the end of
the reel. For this feature to work, reset the tape counter when installing
a fresh Chemcassette
®
. Do not reset the tape counter if rethreading or
realigning a previously installed Chemcassette
®
.
The CM4 can detect common human errors during the tape loading
process to increase the integrity of monitoring. Each Chemcassette
®
includes a unique 12-digit Chemcassette
®
Identification (CID) number that
identifies the manufacture date, the Chemcassette
®
type and the serial
number. This number is entered into the CM4 during tape loading.

®
Label with CID
NOTE:
Disabling the counters eliminates faults that would otherwise occur
when the Chemcassette
®
supply is low (24 hrs remaining) or when the
internal and external filters need to be replaced. See
Section 7.8.1
to
enable/disable the Chemcassette
®
the filter counters. If any counter is disabled, the reset prompts for that
counter will not appear as shown in
Section 7.8.1
