3BUS 208 000 R1301116 Measurement Setup
Figure 6-3 NT Workstation Basis Weight Health Report - Heater
Smart Ash and Smart Basis Weight
Temperature controller setup consists of setting control set points and adjusting the
air flow. The set point for both the source and detector module should be the same
(see Table 6-13 on page 117). The air flow should be adjusted for 4 - 4.5 scfm air
flow for each module.
1. Be sure that the Ash and Basis Weight sensor modules have been off-sheet and
powered down so that the heads are cold.
2. Turn off the air flow to each module. The valves are located on the air manifold
on the back of the basis weight source and detector modules. Valves should be
marked.
3. Set the temperature set point for each module.
Note: This adjustment must be made before the source controller begins
to operate. If additional time is required, move the source set point
to a higher temperature. Be sure not to leave the controller at this
higher temperature.
4. Adjust the source air flow while observing the source heater current at the
Service Workstation. Adjust flow for 2.2 amperes, this should correlate to about
4.0 scfm. The on time duty cycle must be at 100.
5. Repeat Step 4. for the detector module flow and detector heater current.
6. Reset the temperature set points for the desired operating point as directed in
Table 6-13.
