8.5 Function 4.4 – Reset System
Purpose
Use the reset system function to:
• Delete all operator-programmed settings and replace them
with the factory default setting
• Clear the system of a software error
Caution
All user-programmed settings will be set to default.
Instructions
1. Press PROGRAM to exit Monitor Mode.
2. From the 4–SERVICE MENU, choose the subfunction 4–
RESET SYSTEM.
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.

3. Press either:
• 1 to reset all system parameters to the factory defaults
and to reboot the CM4
or
• 0 to keep the current system parameters
Use the configuration function from the Set-Up menu to retrieve a
previously saved configuration (see Section 7.5).

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® and Section 7.8.2 to enable/disable
the filter counters. If any counter is disabled, the reset prompts for that
counter will not appear as shown in Section 7.8.1.
