Mounting Select a location that will allow for sufficient air movement around the control. Overall Dimensions: 6.85 x 2.95 x 7.28 inches (174 x 75 x 185 mm) Note: Unit must be mounted vertically to have best possible cooling effect. 1. Using the dimensional data from Figure 1, drill and tap 4 mounting holes for either 4.
System Wiring Controllers If only a single brake is to be used on the MCS2000-DRV2, then skip to either the 24 volt brake wiring section, page 8 or the 48 volt brake wiring section, page 10. 3. Connect a wire from terminal Out 2 (V) on the MCS2000-ECA to terminal number 3 InB 0-10 V on the MCS2000-DRV2. Insure that both terminals are tightened securely. 4. Connect a wire from terminal Out 1 (OV) on the MCS2000-ECA to terminal number 4 OV on the MCS2000-DRV2.

1. Connect the brown wire [Channel 1 Out (V)] from the connector cable on the MCS2000-CT controller to terminal number 1 In A 0 – 10 V on the MCS2000-DRV2. Insure that the terminal on the MCS2000-DRV2 is tightened securely. 2. Connect the green wire [Channel 1 Out (0V)] from the connector cable on the MCS2000-CT controller to terminal number 2, 0 V on the MCS2000-DRV2. Insure that the terminal on the MCS2000-DRV2 is tightened securely. 3.
Power and Brake Wiring 3. Wire the brake for Channel “A” on terminals 5 and 6 of the MCS2000-DRV2. Make sure the terminals are securely tightened. 4. If a brake is to be used on Channel “B” wire the brake to the Channel “B” terminals 7 and 8 on the MCS2000-DRV2. Make sure the terminals are securely tightened. 24 Volt Systems 1. Wire the positive (+) side of the 24 volt DC power supply to terminal 10 of the MCS2000-DRV2. Make sure that the terminal is securely tightened on the MCS2000-DRV2. 2.

Note: Warner Electric Tension brakes are not polarity sensitive, so wiring between terminals on the MCS2000-DRV2 and brake are not sensitive to the + and - designations. The following 24 volt tension brakes can be used with the MCS2000-DRV2 Driver for 48 volt operation with overcurrent feature.
System Start-Up 24 Volt System 1. Prior to applying power, double check all wiring between Tension Control and Driver, Driver and Brake or Brakes, and 24 Volt Power Source and Driver. 2. Once connections are checked and confirmed that all wiring is correct, turn power on to the Power Supply and Controller and observe “RED” and “GREEN” LED Indicators on the Driver. 3. 4. If everything is normal, then the “GREEN” LED will be on and “RED” LED’s will be off.
5. Adjust the anti-residual output for Channel “B” as follows if a brake is used on this output. If no brake is used, then disregard this portion of the start-up. Proceed to step 6. 5a. Using a digital DC Voltmeter, connect the positive lead to terminal 3 and the negative lead to terminal 4 of the MCS2000-DRV2 for Channel “B” input. 5b. Adjust the Tension controller being used to give a 0 VDC reading on the Channel “B” input. 5c.
6. Adjust the input voltage from the tension controller to the Channel “A” input observing the “RED” and “GREEN” LED’s. If a 24 volt system is being commissioned, then only the “GREEN” LED should be functional unless there is a problem with the controller, brake, or wiring. 7. If no other indications are present on the LED’s then the system is functioning properly. The intensity of the “GREEN” LED does not change with the amount of output current being supplied to the brake. 8.
4d. Now slowly adjust the anti-residual potentiometer “A” clockwise while feeling the reaction on the brake. When the optimum anti-residual output is obtained, the brake will be very free to rotate without much resistance. This is best if done at core diameter. Note: Using a meter across the brake “A” terminals 5 and 6 as noted in 4c above, the voltage observed should be negative at this time. 4e. Once this point is found, do not adjust this potentiometer further or the brake can re-engage. 4f.
Note: Using a meter across the brake “B” terminals 7 and 8 as noted in 5c above, the voltage observed should be negative at this time. 5e. Once this point is found, do not adjust this potentiometer further or the brake can re-engage. 5f. This completes the adjustment for the Channel “B” anti-residual. Proceed to step 6. The following LED indications will be present with anti-residual current is applied to the brake. The Channel “B” is operating in the anti-residual mode with the following indication.
7. If no other indications are present on the LED’s then the system is functioning properly. The intensity of the “GREEN” LED does not change with the amount of output current being supplied to the brake. This completes the checkout of the “A” Channel. Proceed to step 9. 8. If LED indications are present other than those described above, proceed to the troubleshooting section on page 17 to determine cause and appropriate action to take. 9.
Figure 6 LED Indicator Operations and Descriptions - Normal Conditions Note: Each Channel “A” and “B” can be operated independently, so one channel can have one set of indications while the second channel can have a completely different set of indications. This will be dependent on how controller is set to operate the MCS2000-DRV2 Driver. System Troubleshooting Troubleshooting the MCS2000-DRV2 Dual Channel/Dual Voltage Driver is fairly straight forward.
The following diagnostic indications are possible with the two indicator LED’s on the face of the controller.
Other Potential Faults Symptom Possible Solution Check LED’s for various conditions Check Incoming DC Power to MCS2000-DRV2 either 24 VDC or 48 VDC. Check that power is applied. No Output to Brake If unit has power, check that input signals to Input “A” and Input “B” vary between 0 and 10 VDC. Check that brake coil is not open by doing a resistance check on the magnet coil. Refer to the Tension Catalog for proper resistance. Check that brake is wired to the MCS2000-DRV2.
