Draft Transmitter Adjustments Attachments: Applicable Hauck Drawings These instructions are intended to serve as guidelines covering the installation, operation, and maintenance of Hauck equipment. While every attempt has been made to ensure completeness, unforeseen or unspecified applications, details, and variations may preclude covering every possible contingency.
For optimum use of the BCS panel, it is suggested that the drawings provided by Hauck be referred to for limit switch and valve installation and wiring. In the event that a recommended switch or valve is not used, it may be necessary to connect jumper wire(s) between appropriate terminals in the control panel or burner junction box.
Install the stack temperature thermocouple in the dryer exhaust duct to sense exhaust gas temperature. See Appendix G. for installation instructions. Install a Hauck Rapid Response material temperature thermocouple in the material discharge chute to sense the temperature of the material leaving the dryer. See Appendix H.

Page 4 BCS6000B-9 IMPORTANT Thermocouple cables must be separated from AC power and control wiring to avoid interference and nuisance shutdowns. Observe polarity when making thermocouple connections. Regardless of thermocouple type, the red wire is always negative. A pressure tap for the dryer draft transmitter should be located in the 10 o’clock or 2 o’clock position on the dryer breech.
Page 5 BCS6000B-9 E. ADJUSTMENTS and FINAL CHECKOUT: Record all settings on the CONFIGURATION RECORD SHEET provided in Appendix B. IMPORTANT The burner control motors incorporate a position feedback slidewire. A 5 Vdc supply voltage from the panel is connected to the slidewires in order to generate 0 to 5 Vdc position feedback signals for the PLC.

Page 6 BCS6000B-9 CONTROL LOOP TUNING Screen After setting and recording all parameters on the motor calibration & setup screen, press MAIN MENU key to return to the menu screen then select the CONTROL LOOP TUNING button to display the loop tuning screen. This screen is used to enter tuning constants for each of the three PID control loops.

Page 7 BCS6000B-9 DRAFT CONTROL Enter a draft control PURGE SETPOINT for use during the burner purge sequence. Set this value higher than the normal draft setpoint to prevent dusting as the air damper drives open for purge. Enter LOW FIRE and HIGH FIRE SETPOINTS for draft control. The draft setpoint will automatically ramp from the low fire to the high fire setpoint as the burner firing rate increases.
Page 8 BCS6000B-9 Time and Date Setting Simultaneously press the upper left and lower left corners of the touchscreen to enter the screen setup mode then select CLOCK to access the time and date settings. Use the keypad to enter the desired value then press Sec, Min, Hr, Day, Mon, or Yr as applicable. For example, to set the month to September, use the keypad to enter 9, then press Mon.
Page 9 BCS6000B-9 Setup an analyzer to monitor stack or drum emissions. With the burner firing in manual at approximately 10% output, select the bias point setting screen. Allow the analyzer readings to stabilize, then increase or decrease the air input, if required. Make small adjustments and allow readings to settle after each change.

Page 12 BCS6000B-9 H. TROUBLESHOOTING Use the HELP screens on the touch screen or refer to the following table. MESSAGE DIAGNOSTICS The difference between the Zero and Span feedback values of each CONTROL MOTOR CALIBRATION motor must be greater than 3300. Verify that the motors travel full REQUIRED stroke during the motor calibration procedure.

Indicates low PLC battery voltage. The battery compartment is REPLACE PLC BATTERY located in the CPU. A replacement battery is available from Hauck (part no. 62311) or Automation Direct (part no. D2-BAT-1). *The control motor and excess fuel faults all indicate possible problems with the burner control motors or the position feedback circuits.

Page 15 BCS6000B-9 APPENDIX A: OPERATOR INTERFACE SCREENS MAIN SCREEN This screen displays overall system status and is the default screen on system power-up. It provides AUTO/MANUAL control selection and setpoint (SP) inputs for the temperature control loops. Note that the message box in the lower left corner of the screen appears on all screens to provide the operator with system status messages.

Page 28
Page 28 BCS6000B-9 NOTE During normal operation, the thermocouple should be rotated once a month to expose a different area of its surface to the abrasive forces of the material. This procedure will increase the effective life of the thermocouple. If excessive wear occurs, a protective tube may be added to shield the shaft in the region of the high velocity flow.
