DYNTTS

Replacing a DYNTTS power supply and Opto-Isolator board (AB Drive Type)

Unplug the connectors to the PSU.

To remove the old PSU, the drive for the Radial motor will need to be lifted off of its fixings.

Unscrew the 4 countersunk screws that hold the PSU in place.

Disconnect the spade connector’s that join the PSU to the terminal block.

The ballast resistor (small resistor connected to provide load to the PSU) must be removed if present.  Unscrew and disconnect if this is connected to the black plate or leave attached to the PSU if bolted to the PSU frame.

Fit the new PSU using the screws supplied (M4 X 16) The PSU has been fitted to a plate to make fitting easier.

Connect the output loom as shown and connect to the terminal block.

Use the original power mains wire and plug in the opposite end of the PSU.

Switch on the machine and check the voltages on the Power supply are correct as shown. Connect the Black probe of the multi-meter to the Black wire.

+5 volts: Black, Red

+12 volts: Black, Violet

+24 volts: Black, Orange

• 12  volts: Black, Blue

The photo below shows what the new power supply fitted and wired correctly should look like.

Bolt the Opto board to the 9 way D type connector and fix in place using the hex posts supplied. Connect the 9 way loom to the opto board, and then the opposite end to the PSU terminal block.

The image Below shows the Encoder board at the top of the panel, with the 25way D type connector underneath.

All wiring will be completed by GDS but the connectors orientation will be the following:

P3

 + = +24V Orange from PSU

• = 0V Black

P4

Top pin 4 - Empty

Pin 3 Blue 0V

Pin 2 red +5v from drive

Pin 1 - Empty

Connector ends to encoder board
