Power Board Output Test (Molex Connector)

1) Make sure that nothing is connected to the main terminal block.

2) Turn the ON/OFF switch to the ON position (to the right).

3) Place the common lead of a multimeter into the ground test point in the upper left corner of the power supply board.

4) Select OHMS on the multimeter.

5) Place the positive lead on pin 2 of the main terminal block. The value should be 0 (zero) to 1 (one) ohm.

6) Now place the positive lead on pin 1 of the main terminal block. The value should be greater than 200 ohms.

7) Disconnect the Molex connector that runs between the card cage and the power supply board.

8) Verify that the power to the reader board is disconnected.

9) Turn the ON/OFF switch to the OFF position (to the left).

10) Install the test block with +24RDC into the main terminal block. Pin 1 is +24VDC and pin 2 is ground.

NOTE: Procedures for +12VDC units are the same except for the input voltage.

11) Turn the ON/OFF switch to the ON position (to the right).

12) Select DC volts on the multimeter with a range that will measure +24VDC.

13) Verify that LEDs CR1, CR2, and CR3 on the power supply board are ON.

14) Verify that DC voltage is as follows:

TP1	=	+5VDC
TP2	=	–12VDC
TP3	=	+12VDC
TP4	=	+12.75VDC

15) Place the common lead of a multimeter into the ground test point in the upper left corner of the power supply board.

16) Use the positive lead to verify the following voltages at the Molex connector coming from the power supply board.
