B Series Degreaser Operation
Rev G Page 66
• Vapor Level Probe Missing. The temperature sensor located above the condensing coil has
failed. The display will show “dE5”. Press HEAT to reset the fault when the condition has
been corrected.
• Lower Vapor/Spray Probe Missing. The temperature sensor located below the condensing coil
has failed. The display will show “dE6”. Press HEAT to reset the fault when the condition
has been corrected.
Warning: Always determine the cause for the shut down before attempting to restart the B Series.
4.2.7 Restarting the Heat
After the fault has been corrected, press the “HEAT” membrane switch on the control panel to
clear the fault display and restart the heat.
4.3 READY Light
The green “READY” indicator lights when the sensor located below the condensing coil senses
the high temperature associated with the presence of solvent vapors. It shows that the vapor layer
has been established. It may take as much as 15 minutes for the READY light to be displayed
when cold starting.
The spray will not operate unless the “READY” light is on.
4.3.1 Turning the Recirculation Pump On and Off and Adjusting the Flow
Press the “RECIRC” membrane switch to toggle the recirculation pump on and off. The
RECIRC indicator will light. The pump will operate.
Adjust the flow using the Recirc Return Shut-off Valve (See Figure 2-1) so that the surface of
the ultrasonic tank is disturbed but not violently agitated.
Note: Excessive recirculation flow will interfere with ultrasonic action.
4.3.2 Turning the Ultrasonics On and Off
Note: Operating the ultrasonics continuously may cause the ultrasonic temperature to rise above
the setpoint. Except for degassing, operate the ultrasonics only when parts are being cleaned.
4.3.2.1 Manual Mode
Press the U/S membrane switch to toggle the ultrasonics on and off. The U/S indicator
will light. Ultrasonics will not operate if heat is off. The ultrasonics will not operate if
the optional lift is not in cycle or programmed for the ultrasonics to be on in manual
mode.
4.3.2.2 Automatic Operation TDR
Turn the controller U/S switch OFF if the TDR is programmed to turn the ultrasonics on
and off. Program the TDR Output 1 On then Off to toggle the ultrasonics On. At the
completion of the ultrasonic period, program Output 1 On then Off to toggle the
ultrasonics off. See the sample TDR program (Section 3.14.3.)
Operating the control panel switch during automatic operation may cause the ultrasonics
to get out of synchronization with the TDR.
