Motor / Brake Precautions
To ensure proper operation of the brake, a separate case
drain back to tank must be used due to the possibility of
return line pressure spikes. A simple schematic of a system
utilizing a motor/ brake is shown in the diagram below.
To achieve proper brake release operation, it is necessary
to bleed out any trapped air and fill brake release cavity and
hoses before all connections are tightened.
It is advisable that the brake release port should be
positioned as near the top of the unit in the installed position.
Caution
All Adan motor / brakes are intended to operate as static
parking brakes, the system should be designed to bring the
load to a stop before the brake is applied.
With large displacement motors it is possible for the motor
to produce higher torques than the brake will hold, it is
critical that the maximum system pressure is limited in these
applications. It is vital that the system relief be set low enough
to ensure the motor is not able to produce more torque than
the brake can hold.
Failure to do so may result in serious injury or death.
