Insert a #4-40x1/4” Phillips SEMS screw in each of the 4 mounting holes. Make the
screws snug, but not too tight.
Test the Input Selector PCB Power Drain
Here is the input selector power drain test procedure:
1. Connect the IEC power cord to the PR101 and the AC mains (wall socket).
2. Switch on the AC power.
3. Measure the DC voltage on the input selector TB13.
a. The voltage from POS12 to GND should be +12+/-0.5 Volts.
b. The voltage from NEG12 to GND should be -12+/-0.5 Volts.
7. Disconnect the IEC power cord and switch off the AC power.
If the voltages are correct, go onto the next step. If the voltages are not in tolerance,
review your work for errors, particularly backwards electrolytic caps or backwards ICs in
the input selector board. Do not go farther until the voltages are correct. If you reach a
road-block, send email to dan@akitika.com for troubleshooting advice.
Install 16 pin ribbon cable
Figure 34-16 pin ribbon cable orientation and installation
Here is the input selector control interface test procedure:
1. Locate the 16 pin ribbon cable from the wire kit. Note that the ribbon cable has
keyed connectors.
2. Refer to Figure 34 for the cable orientation. Note that the red stripe on the cable
faces up when connecting to the controller.
3. Touch the chassis first. You may get a static electricity shock, but better you than
the controller (it has protection, but let’s avoid exercising it).
4. Connect one end of the cable into the accompanying socket on the input selector
PCB. Don’t force the connector…if it doesn’t go, re-check the connector’s
orientation.
5. Connect the other end of the cable into the accompanying socket on the controller
board.
