Resumen del manual
3. With power reapplied, let unit start heating up, or enter the Tech Mode in Special Program mode and check the relays in the output test. (See Section 4-3 of the Operator’s Manual.) 4. With the component energized (example: blower motor), 0 volts should show on the output side of the relay, and 12 volts on the input side. 5. With the component not energized, 208 or 240 volts should show on the output side of relay, and 0 volts on input. 6. If voltage varies from steps 4 and 5, remove power to unit, pull input wires from relay and place leads of meter onto input wires. Reapply power to unit. When unit is running, the input wires to relay should show 12 vdc. If this proves true, the relay is faulty. Replacement: 7. Remove power supplied to unit. 8. With wires removed and labeled, use a Phillips head screwdriver and remove appropriate relay from unit. 9. Coat the back of the relay with the thermal joint Step 8 compound. Failure to use the thermal joint compound will shorten the life of the relay. 10. Install new relay and replace wires. 11. Replace side panel and reapply power. Step 8 2-14 503 SCR-6/8 2-19. HIGH LIMIT The high limit is a safety device which senses an overheating situation inside the rotisserie (around 500.F), which shuts the heat off in the unit. Once the temperature inside the unit goes down, then the high limit automatically resets and the unit can then be heated. All SCRs have two high limits. The SCR-6 and SCR-8 both have a 450.F high limit and a 500.F high limit. The SCR-3 has a 285.F high limit and a 450.F high limit. European, CE units have 450.F, manual reset high limits. These have a reset button on them and must be manually pressed. Follow the steps in the procedures in this section to access this high limit. 1 . Remove electrical supplied unit. Step 3 To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle. 2. Remove the side panel closest to the controls. 3. Pull the wires from the 500.F high limit (285.F on SCR-3s) and check for continuity between the terminals. When the cabinet temperature is below 300.F, the high limit should show continuity. If it does show continuity, continue on with this section. If it doesn’t, replace this high limit with a new one and unit should then be ready for use. 4. If the 500.F high limit shows continuity, the 450.F high limit could be bad.To access this high limit, remove the insulation washer from the stud and remove the insulation. For CE, European units, the reset button can be accessed at this time. Use a pen, pencil, or screwdriver to press the button through the hole in the box. If unit now heats, replace the insulation and side panel and unit is ready for use. If unit does not heat, proceed with the following steps. 503 2-15 SCR-6/8 2-19. HIGH LIMIT (Continued) Units with a small diameter hole, in the high limit box, must follow the preceding steps to access the wires and mounting nuts of the high limit. Units with a large diameter hole can access the wires and mounting nuts from the hole in the front of the box. 5. Remove the fan assembly from the interior of the unit. Step 6 Step 7 Step 8 6. Using a 7/16” socket, remove the nuts securing the blower and pull the blower from the studs. 7. Using a 3/8” socket, remove the nut securing the probe bracket, and pull the bracket from the stud. 8. Cut insulation to access the top, right stud of the blower. 9. Pull the box from the unit to access the high limit. 10. Pull the wires from the high limit, and take a continuity check across the terminals. If it shows continuity, the high limit is good. If the high limit shows no continuity and the temperature is below 300.F, proceed with the following steps. 11. Using a 5/16” socket, remove the two nuts securing the high limit and remove the high limit. 12. Replace with a new high limit and replace the wires. 13. Replace the box, blower and blower nuts, insulation, insulation washer, probe bracket and nut, and side panel. 14. Unit is now ready for use. 2-16 503 SCR-6/8 2-20.
