Electrical Cabinet (EC)
TJ8300 / TJ8500General Description
The electrical cabinet is located inside the electronics cabinet.
The electrical cabinet (structure) is comprised of the base and the panel door.
It receives the main power supply line from the machine – 3X230VAC + Natural + GND – (max.) total of 63A (per phase).
The electrical cabinet is responsible for the following functions:
PDU – power distribution to all components in the machine
Operation of drum heating
Operations of pumps (vacuum and evacuation)
Protections (overheat and under speed)

TJ8300 / TJ8500Electrical 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).

TJ8300 / TJ8500Electrical 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.

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.
