Power Supplies

All power supplies are connected to the PDB. Power is supplied from the PDB to the various components such as MCE and GENINE boards via the CAN Bus.

There are 4 power supplies for MCE devices:

• PS1=CAN Bus, Pneumatics Unswitched 24V (166-00056)
  Order kit 500-02643A to replace 166-00056 or 13-5094.

  PS1 supplies power to all of the devices on the CAN bus (PDB, MCE, & GENINEs (if installed)). Each of these boards locally regulate the 24V down to the voltage levels they require. This power supply in always on when the Trendsetter is on.

• PS2=Carriage Motor Switched 48V (166-00058)
  Order kit 500-02645A to replace 166-00058 or 13-5094.

  This is the same unit as PS1. It should be adjusted to 48 Volts. PS2 supplies power to the carriage drive. This power supply is switched by the PDB according to the state of the interlocks and the SIO keyswitch.

• PS3 (TH1.7 and TH2)=Write Laser Switched 48V (166-00057)
  Order kit 500-02646A to replace 166-00057 or 13-4832.

  PS3 supplies power to the thermal head write laser. This power supply is switched by the PDB according to the state of the interlocks.

• PS4 (TH1.7)=Laser Logic Unswitched 48V (166-00057)
  Order kit 500-02648A to replace 166-00057 or 13-4832.
  PS4 (TH2)=Laser Logic Unswitched 48V (166-00059)
  Order kit 500-02649A to replace 166-00059 or 13-4791.

  PS4 supplies power to the thermal head for all functions except the write laser. This power supply is switched by the PDB according to the state of the interlocks.

See the PDB Wiring Diagram in the Trendsetter GMCE/TMCE Wiring, Safety, and Block Diagrams, (contains a POWER SUPPLY ALLOCATION TABLE at the bottom of the page with more information on the above power supplies)

Safety Loop

See the Safety Circuit Wiring Diagram in the Trendsetter GMCE/TMCE Wiring, Safety, and Block Diagrams

When servicing the device, a Power Box Disconnect Switch Service Override tool (15-3526) is needed to turn the power on when the inner access panel has been removed.
