Refer to NEW SCRAPER BLADE INSTALLATION PROCEDURE. □ Check quad ring and replace if required. Refer to QUAD RING REPLACEMENT PROCEDURE. □ Inspect oiler in gear box and fill with oil if required. Refer to OILER FILLING PROCEDURE. □ Inspect air filter cartridge and replace if required. Refer to AIR FILTER REPLACEMENT PROCEDURE. SIX MONTH MAINTENANCE □ Grease trunnion housings in gear box and on outboard bearings. □ Test pressure relief valve. Refer to PRESSURE RELIEF VALVE TESTING PROCEDURE. OPERATING SEQUENCE - HEATING STEP ACTION RESULT 1 RESULT 2 1. Close main circuit breaker. 120 volts is supplied by primary contactor to kettle On/Off switch and tilt relay contacts. Power supplied to tilt assembly. 2. On/Off switch on kettle switched to ON. 120/16 volt transformer supplies power to control boxes. Amber LED is illuminated. (Used prior to July 2004) 3. Control box. A/ Requires grounded probe to function (pin #5). B/ More that 6 volts at pin #2. Control box energizes 12 volt DC relay (pin #6). a/ b/ Green LED illuminates. 12 VDC relay contacts close. 4. 12 VDC relay contacts close. A/ Blower energizes. a/ Air switch contacts close. B/ 120/25 volt transformer energizes. a/ 25 volts supplied to ignition module. C/ 120 volt supplied to ignition module. 5. Ignition module. Supplies 120 volts to ignition. Within 20 seconds ignitor glows red. 6. 120 volts turned off to ignitor A/ Gas valve is energized. a/ Burner ignites. B/ Ignitor becomes sensor. a/ b/ If temperature drops in chamber gas valve is deenergized within five seconds. Ignitor will try twice more to light before locking out. 7. Temperature reached. A/ Less than 6 volts at pin #2. Control box de-energizes 12 volt DC relay (pin #6) a/ b/ c/ d/ Green LED turns off. 12 VDC relay contacts open. Blower turns off. 25 volt transformer de-energizes. QUICK CHECKS: Potentiometer - Range 0 - 50K, Safety Thermostat - Normally Closed, Thermistor - Range 0 - 100K, Water Level Probe - Must be submerged in water for burners to work OPERATING SEQUENCE - AGITATOR 1. On/Off switch closed. A/ Three phase contactor closes to supply power to variable speed drive. a/ Indicator light is energized. 2. Start button momentarily depressed. A/ Power to agitator motor a/ Motor comes up to speed. 3. Speed control turned up. A/ Motor speed increases. OPERATING SEQUENCE - POWER TILT 1. Turn and hold tilt switch In down position. A/ Relay 2 is energized. a/ Tilt motor is energized. 2. Kettle tilts until limit switch is depressed. A/ Power interrupted to down side of tilt switch. a/ b/ Relay de-energized. Motor stops. 3. Turn and hold tilt switch in up position. A/ Relay 1 is energized. a/ Tilt motor is energized. 4. Kettle tilts until limit switch is depressed. A/ Power interrupted to up side of tilt switch. a/ b/ Relay de-energized. Motor stops. KETTLE SAFETY INSPECTION CHECKLIST Regular inspection and maintenance of units is essential to obtain trouble free and safe operation of equipment. Inspections must include testing of the pressure relief valve and checks of the operating system to insure that it has not been altered. No safety features designed into the equipment should ever be tampered with. Tampering with or bypassing controls is a very dangerous practice and unfortunately we have seen several cases of this. Following is a short list of the most common and the most dangerous alterations performed on kettles. SAFETY VALVE: This illustrations show the correct configuration of a factory installed Safety Valves. Any modifications are unacceptable. 1 2 Incorrect Installations 3 1 Safety valve has plug threaded into the discharge opening preventing any steam from escaping. 2 3 4 Safety valve's tube diameter has been reduced. Safety valve is sticking, frozen shut or plugged. To test, refer to PRESSURE RELIEF VALVE PERIODIC TESTING. Safety valve is plumbed to a drain or water line creating back pressure and reducing flow. 4 X Plug X Tube diameter reduced X Frozen, stuck, or plugged X Plumbed to drain or water line SAFETY THERMOSTAT: Probe removed partially completely bypassed Incorrect Installations Safety thermostat probe is not completely inserted into tubing. Safety thermostat probe is removed from tubing. Safety thermostat electrical connection is bypassed. 2 3 Low Water Level Probe: X Probe bypassed by running (A) an additional wire X Probe bypassed by (B) grounding the connecting wire Operating Thermostat: ✓ 260° - 270° MAXIMUM KETTLE TEMPERATURE If maximum temperature is not in this range (on empty kettle), refer to the CALIBRATING PROCEDURE. Air Switch Incorrect Installation X Switch electrically bypassed AIR FILTER REPLACEMENT PROCEDURE 1 Disconnect air supply and bleed system. 2. Remove cover on console (see SIDE BOX - PNEUMATICS). 3. Check for filter location 4. Push lever down and rotate bowl/ guard assembly 1/8 turn. 5. Push down on bowl/guard a...
