CDBR-B Installation Instructions - March 2013

3. Remove connector 3CN on 1PCB and place the ohmmeter leads on terminals 1 and 2 of the

connector. The meter should read infinite Ohms. (Normally Open Thermal Relay (1THG).

Replace connector 3CN.

4. Place the 4CN jumper on 1PCB to the “Master” position.

5. 230V Models

Verify that the Power Supply Voltage Selection Jumper is set to 230V.

With a variable DC power supply, which is capable of producing 400 VDC output, apply the DC

voltage to terminals (+) and (-). Slowly increase the voltage to approximately 50V, at which time

the Charge LED on 1PCB should illuminate. With a DC Voltmeter, monitor terminals (+O) and

(-O), and continue to increase the DC voltage to 380 VDC, at which time you should see the DC

Voltmeter turn on to read the 380 VDC applied voltage, and the Brake LED on 1PCB should illu-

minate. At this same time, you should also read 15 VDC across terminals 5(+) and 6(-), which

indicates that the output, to activate a slave CDBR, has turned on.

460V Models

Verify that the Power Supply Voltage Selection Jumper is set to 460V.

With a variable DC power supply, which is capable of producing 800 VDC output, apply the DC

voltage to terminals (+) and (-). Slowly increase the voltage to approximately 50V, at which time

the Charge LED on 1PCB should illuminate. With a DC Voltmeter, monitor terminals (+O) and

(-O), and continue to increase the DC voltage to 780 VDC, at which time you should see the DC

Voltmeter turn on to read the 780 VDC applied voltage, and the Brake LED on 1PCB should illu-

minate. At this same time you should also read 15 VDC across terminals 5(+) and 6(-), which

indicates that the output, to active a slave CDBR, has turned on.

575V Models

Verify that the Power Supply Voltage Selection Jumper is set to 575V.

With a variable DC power supply, which is capable of producing 1000 VDC output, apply the DC

voltage to terminals (+) and (-). Slowly increase the voltage to approximately 50V, at which time

the Charge LED on 1PCB should illuminate. With a DC Voltmeter, monitor terminals (+O) and

(-O), and continue to increase the DC voltage to 950 VDC, at which time you should see the DC

Voltmeter turn on to read the 950 VDC applied voltage, and the Brake LED on 1PCB should illu-

minate. At this same time you should also read 15 VDC across terminals 5(+) and 6(-), which

indicates that the output, to active a slave CDBR, has turned on.

6. Remove power from terminals (+) and (-).

7. Place the jumper on 4CN on1PCB to the “Slave” position.

8. Apply power (325 VDC for 200V models, 650 VDC for 400V models, and 812 VDC for 500V

models) to terminals (+) and (-). Using a separate DC power supply, apply 7 VDC to terminals

1(+) and 2(-) on 1PCB. This 7 VDC signal should cause the main transistor 1TRM to turn on and

you should read the applied DC Bus Voltage across terminals (+O) and (-O), and the Brake LED

on 1PCB should illuminate.

9. With power still applied to terminals (+) and (-), monitor terminals 3 and 4 on 1PCB with an

Ohmmeter. This meter should read Infinite Ohms. Place a jumper across the terminal switch

(pins 1 and 2 on 3CN), which should cause the Fault Relay to change state, and 0 Ohms should

read on the Ohmmeter.

10. Remove the terminals (+) and (-) and return the 4CN jumper on 1PCB back to the “Master”

position.
