5 Temperature limiter DANGER • Electric shock hazard! High voltage inside electric panel. DO NOT touch bare terminals and/or wires. TC4SP unit (Fig.6) has three setting groups: 1st setting group, 2nd setting group, and SV setting group (the main indication mode). The settings must be changed in the same order as they appear in the list. -
Page 9: Chamber Deep Cleaning
6 Chamber deep cleaning Over time, corn dust and husk might be accumulated in hidden areas of the chamber. This negatively a ects normal airflow in the corn supply tube. If corn supply tube clogged with popcorn frequently, then it is necessary to clean those areas of the chamber. Chamber section view Figure 7: Chamber deep cleaning 1. -

7 Heating circuit Figure 8: Elements of heating circuit 7.1 Heating elements check 1. Unplug the machine and see Fig.8. 2. Measure the resistance between T1 and T2; it must be 20-22 Ohms. (a) If it reads OL, then check heaters wiring, busbars, and the heaters directly. (b) If it reads 30-31 Ohms, then one of the heating elements is fault, see the next steps. -
Page 11: Solid-State Relays Check
7.2 Solid-state relays check 1. Turn the machine on. 2. Make sure LED indicators are o . 3. Check to see if the mains voltage (208 Vac) presents at L1. (a) If negative, perform Contactor check, see below. (b) If Contactor check positive, then disconnect the machine and check the consistency be- tween L1 and 1. -
Page 12: Temperature Limiter Output Check
(a) If no mains voltage presents at 2, 4, 6 then unplug the machine, open the plastic hatch covering armature plunger Y; use a suitable tool to press the plunger inside the contactor. While pressed terminals 1,3,5 must be closed to 2,4,6, respectively. If the plunger cannot be moved inside smoothly, or doesn’t close the terminals, the contactor must be replaced.
