CL4 & CL8 Manual
End of line particulate filters may be purchased from DOD technologies (see appendix A)
3.4 Exhaust tubing
The exhaust line must be 3/8” OD x 1/4” ID tubing with a maximum length of 25ft. Polyethylene is
recommended although polypropylene or Teflon may also be used.
Exhaust tubing may be purchased from DOD technologies (see appendix A)
3.5 A/C Power
A 6ft power cord is included
–
DO NOT use extension cords with the CL4/CL8. Longer cords are available
from most electrical supply stores.
3.6 Output Wiring
Figure 3.2 details the connection method for both the standard relay output module and the optional 4 to 20
ma modules.
See Appendix B for a listing of output module connections.
3.6.1 Standard Output Relay Module Wiring
The standard output module requires an external 24V supply connected to V1+/- and V2+/- (see Appendix B).
Outputs 0-15 are powered through V1 while outputs 16-31 are powered through V2. Each output can handle
up to 0.2 Amps with a total maximum current of 1.6Amps to each group of 16 outputs at any time. See figure
3.6 and 3.7 for information on wiring the CL4/CL8 standard relay outputs.
IMPORTANT:
All points require filtration to prevent dust accumulation in tubing and
internal damage to the CL4/CL8. Dust that collects in the tubing or the internal
system may cause sample loss and inaccurate gas concentration readings.
