CL4 & CL8 Manual
Chapter 4 - Setup & Configuration
4.1 Set system date and time
See section 5.2.2
4.2 Gas Selection
Each point on the CL4/CL8 must be setup for the appropriate gas and configured accordingly. See section
5.2.1 for information on selecting the gas for each point.
4.3 Alarm Settings
See section 5.2.a for information on how to adjust the alarm settings after the gas has been selected for each
point.
4.4 Output Relays
The CL4/CL8 supports both energized and de-energized relays and may be configured for either latching or
non-latching faults/events.
When configured for energized relays, the outputs are normally in a high state and change to a low state
when the corresponding fault / alarm occurs. De-energized relays work in the opposite manner. See section
5.2.f. When the power is ON, the Power Loss relay is always in the normally high state.
When latched outputs are selected (section 5.2.f), any fault or a
larm that occurs will remain until the ‘fault
reset’ button is touched. If non
-latching outputs are selected the output will reset automatically if, and when,
the condition that caused the fault/alarm goes away.
NOTE
:
A message is added to the event
log each time the ‘fault reset’ button is touched.
4.5 Concentration Logging
Three levels of concentration logging can be configured in the CL4/CL8.
1.
>0
- All concentrations detected >= LDL are added to the concentration log.
2.
AP1
- Anytime alarm level 1 is reached, the concentrations are added to the log.
3.
AP2
- Anytime alarm level 2 is reached, the concentrations are added to the log.
Regardless of which point the gas is detected on, all CL4/CL8 points are logged as long as the trigger is
active. For AP1 or AP2 logging the system will continue to log concentrations as long as the alarm level is
active.
If latching faults are enabled the system will continue to log until the ‘fault reset’ button is touched.
