Verify Brake Picking - MCi iControl User Manual

Verify Brake Picking

To verify that the brake is picking properly:
1. Verify that the iBox Safety OK LED is solidly on. Display the Pattern > Common tab
(View > Configuration > Pattern > Common tab).
2. Set Pattern Scaling to 0% and click Send to send the changed parameter to iControl.
3. Display the Operational Status tab. Note that Brake voltage is charted in the Machine
section of the Operational Status tab.
4. With a digital volt meter set to DC volts,
measure brake output voltage across termi-
nals B1 and B2 (located just below the iBox
panel). (A typical terminal block is shown to
the right. B1 and B2 will be labeled.)
5. Press the Enable and Up (or Down) buttons
to lift the brake. Verify that the voltages on
the volt meter are the same as the com-
manded voltage (Pick voltage / Hold voltage
parameters on the Brake > Voltages tab) and
Brake voltage on the Operational Status tab.
The brake should lift but the car should not
move since Pattern scaling is set to com-
mand zero speed.
6. Change the Pick and Hold voltages to one half the current value of the Pick voltage
parameter and save the new values.
7. Press and hold Enable and Up (or Down) and verify brake voltage again. (The brake will
probably not lift since we are outputting only half the Pick voltage.)
8. Change the Pick and Hold voltages back to their job print settings and save them.
9. Change Pattern scaling (Pattern > Common tab) to 100% and send that value to the con-
troller.
