Step 6: Electrical Connections. Several different
types of controls can be used on the ER-
825. However, only one control can be used
on the ER-1225 electrically released brakes.
If you are installing an ER-825 brake, follow
the procedures in Section II below. When
completed with Section II, proceed to Step 7.
If you are installing an ER-1225, follow the
procedures in Section III below. When com-
pleted with Section III, proceed to Step 7.
Controls
Section II For ER-825 Brakes
ER-825 brakes require a variable voltage or variable
current control to release the brake by offsetting the
magnetic force generated by permanent magnets.
Warner Electric controls, such as the CBC-200
(single channel) or CBC-300 (dual channel), offer
variable output and are suitable for use with ER-825
brakes. Connection should be made in accordance
with instructions provided with the chosen control.
Section III For ER-1225 Brakes
Connect the MCS-805-1 or MCS-805-2 Power
Supply per the following diagram and instructions:
ER brakes are polarity sensitive.
Connect the (+) terminal of the brake to the (+)
terminal of the control and the (-) terminal of
the brake to the (-) terminal of the control. Plus
to plus and minus to minus connections are
imperative.
Put machine in safe condition
so that when voltage is applied to the control
and switch closures are made the brake does
not rotate and machine does not run.
