Machine Electrical Cabinet
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 UV Lamp Head
Operations of vacuum pumps
Protections (overheat and under speed)

TJ8300 / TJ8500Electrical Cabinet Panel
The panel includes: Drum heat controller board – receives the requested UV capacity
level from the computer and operates the UV lamp head via the UV cabinet.
Controls of two under speed protection (tahco generator and under speed sensor).
Controls of two separate Overheat protections – temperature reading from to IR sensors under the drum is compared to preset value in two separate voltage relays. If the potentiometer on the voltage relay is set to 0.8, it means that the overheat message will appear if the relevant IR sensor reads more then 80ºC.
Dryer enable, HA fans and IR controls, controls operations of all pumps.

Voltage relay I – setting the potentiometer to 1 (max) will result in the overheat 1 message at 100ºC .
Voltage relay II – setting the potentiometer to 1 (max) will result in the overheat 1 message at 100ºC.
Normally both units are set to 0.8, which means that the Overheat will be set to 80ºC.
