Status Panel
The LED status panel shows the instrument operating conditions, and it is located on the right side of
the instrument front panel. See
Figure 25 .
Figure 25. LED Status Panel
Each LED lights up when the relevant function is active. Table 11 illustrates the meaning of each
function:
Table 9. Description of the Devices Controlling the Furnaces
Device Function
LTA-1 LEFT
LTA-1 RIGHT They read the values of the thermocouple present in the relevant furnace and
send the signals to the
TCR 1112 board.
SSR LEFT
SSR RIGHT Solid State Relays (SSR) contained in the AC 1112 board.
Each SSR is coupled with a proper safety sensor, which detects any malfunction.
The SSR control the power supply to the relevant furnace and cut off power to
the heating resistor when the thermocouple detects temperature values
exceeding the setpoint.

Device Function
T1 Transformer Supplies 48 V voltage to the right furnace resistor. It is provided with a safety
thermal protection, which cuts off power in case of overheating.
T2 Transformer Supplies 48 V voltage to the left furnace resistor. It is provided with a safety
thermal protection, which cuts off power in case of overheating.
