4.6 Heater Circuit
Refer to figure 4-3.
The Heaterplate contains three heating elements within a parallel
Circuit (1 Kw / 52 ohms for each element). The temperature is
regulated using an Adjustable Temperature Control Device (see
figure 4-4) mounted in series before the heating elements.
In addition, the heating circuit contains two Thermal (Hi-limit) Cut-
outs also electrically mounted in series to the heating elements.
Should the temperature exceed 200
0
C the circuit electrically
interrupted.
