2. Engineer Training Control Unit TJ8300 / TJ8500 Confidential 2 General Description  Located at the bottom of the electronic cabinet  Easy front access for all boards inside the Control unit Control bracket

3. Engineer Training Control Unit TJ8300 / TJ8500 Confidential 3 General Description (Cont.)  The Control bracket concentrates all controls signals between the electronics cabinet and the computer.  The Control bracket is a passive board with DIN connectors for the following boards:  I/O Controller  Sol/Lamp driver  Auxiliary control board (ACB)  Galil board  It also contains D-type connectors for all proceeding input and output connections.

4. Engineer Training Control Unit TJ8300 / TJ8500 Confidential 4 I/O (Type I) Controller  The I/O (type I) controller is placed on the control bracket.  Controls most of the printing unit I/O components.  Receives input signals from I/O components, placed all over the printing unit, and updates their status to the computer.  Provides discrete input and output signals.  Has 64 digital inputs and 56 digital outputs.

5. Engineer Training Control Unit TJ8300 / TJ8500 Confidential 5 I/O (Type I) Controller (Cont.)  Every active input or output switches on with an indicating LED.  Push button for manual reset. RS-232 connector Manual reset Input LEDs (Green) Output LEDs (Orange)

6. Engineer Training Control Unit TJ8300 / TJ8500 Confidential 6 Solenoid Amplifier Driver  The Sol/Lamp Driver is dedicated for I/O (type I) controller outputs.  It boosts 24 VDC for solenoids and indication lamps switching.  It has 32 TTL inputs and a maximum of 32 power outputs.  Each output has its own indicating LED and can handle up to 1 Amp 30 VDC.  Power outputs of the Sol/Lamp Driver are protected against destructive conditions, such as:  short circuit  over-current  over-voltage

7. Engineer Training Control Unit TJ8300 / TJ8500 Confidential 7 ACB (Auxiliary Control Board) The Auxiliary control board is placed on the Control unit bracket and sends the following signals:  Signal for external dryer.  Generates the Iron command.  24VDC CCB detection – In the absence of 24VDC for the CCB, the auto drop signal automatically shuts off.  Converts the communication from RS232 to RS422.
