Engineer Training Electrical Cabinet (EC) TJ8300 / TJ8500 Confidential 11 Electrical Cabinet Panel The panel includes:  Drum heat controller board  Receives the requested temperature from the computer and heats the drum with a combination of IR and hot air fans.  Receives feedback of the real drum temperature measured by the IR sensors.  Controls for two under speed protection (Tahco generator and under speed sensor).

Engineer Training Electrical Cabinet (EC) TJ8300 / TJ8500 Confidential 12 Electrical Cabinet Panel (Cont.)  Controls for two separate overheat protections  Temperature readings from two IR sensors under the drum are compared to the preset value in two separate voltage relays.  If the potentiometer on the voltage relay is set to 1, the overheat message appears when the relevant IR sensor reads more then 100ºC.  Dryer enable  HA fans and IR controls, control operations of all pumps.

Engineer Training Electrical Cabinet (EC) TJ8300 / TJ8500 Confidential 13 Door Panel (Cont.)

Engineer Training Electrical Cabinet (EC) TJ8300 / TJ8500 Confidential 14 Door Panel  Voltage relay I – sets the potentiometer to 1 (max) displays the overheat 1 message at 100ºC.  Voltage relay II – sets the potentiometer to 1 (max) displays the overheat 1 message at 100ºC.  Normally, both units are set to 0.8, which means that the overheat is set to 80ºC.
