ChemLogic® CL96 Operating Manual
The drop-down list for Conc. Logging gives the operator the three available choices for what concentration
data should be logged:
1. All concentrations
2. Those above Alarm Level 1
3. Those above Alarm Level 2.
Only points where gas is detected are logged to the disk. An appropriate event message is always written to
the event log when gas exceeds alarm level 1 or 2 on a per point basis.
The third component of the Logging Configuration is the logging interval. The value entered here determine
how often the concentration is logged to the storage drive. Use the + and – keys to adjust the value from 4 to
120 seconds in 4 second increments.
Idle Timeout
The idle timeout box allows adjustment of the time a critical fault will be issued if any installed analyzer is left
out of analysis. Setting the value to = disables the fault from occurring. Use the + and – keys to adjust the
value from 0-45 minutes.
Output Contact
Energized relays determine the normal state of the relays/outputs. When energized is selected the faults,
general alarm levels, and point outputs will all be energized under normal conditions. When a fault or alarm
occurs, the outputs will become de-energized. The opposite occurs when this checkbox is not selected.
Selecting Latching faults causes faults to remain active until the ‘Reset Faults/Events’ button is pressed to
acknowledge the problem.
Flow Fault Filter
The flow fault filter setting determines the minimum time to filter a flow fault (either high or low flow). For
example: putting this setting to 30 seconds would require a continuous low flow for 30 seconds before a fault
is set AND another continuous 30 second period of corrected flow before the flow is cleared.
IMPORTANT : Hard Disk 1 and Hard Disk 2 are reserved for use by the CL96 system. Each USB
drive installed in the USB Hub will be sequentially named beginning with Hard Disk 3.
NOTE : Flow faults are not affected by the lathing faults option. Flow faults will never be
latched on the CL96 but will always be recorded in the event log when they occur and are
cleared. See below for flow fault filter.
