Patent ID: 8746413

Claim:
A control arrangement for an elevator brake, comprising a control circuit adapted to generate, according to a demand for releasing a first braking member of said elevator brake, a first actuating signal and to generate, according to a demand for releasing a second braking member of said elevator brake, a second actuating signal; a first terminal for outputting said first actuating signal to a first electromagnetic actuator of said elevator brake; a second terminal for outputting said second actuating signal to a second electromagnetic actuator of said elevator brake; said control arrangement being adapted to allow at least the following modes of operation: A) a normal operation mode in which said first and said second actuating signals are supplied synchronously to said first and second electromagnetic actuation means, respectively; and B) a single braking member test operation mode, in which one of said first and second actuating signals is supplied to the respective one of said first and second electromagnetic actuating means, and test operation mode actuating signal for releasing the respective of said first and second braking members for a duration of the test operation mode is supplied to the other one of said first and second electromagnetic actuators, wherein said test operation mode actuating signal is supplied to a third terminal of said control arrangement.
