Abstract:
A control arrangement (100) for an elevator brake, comprises a control circuit (110) adapted to generate, according to a demand for releasing a first braking member of the elevator brake, a first actuating signal and to generate, according to a demand for releasing a second braking member of the elevator brake, a second actuating signal; a first terminal (112) for outputting the first actuating signal to a first electromagnetic actuating means (26) of the elevator brake, a second terminal for outputting the second actuating signal to a second electromagnetic actuating means (30) of the elevator brake; the control arrangement (100) being adapted to allow at least the following modes of operation: A) a normal operation mode in which the first and the second actuating signals are supplied synchronously to the first and second electromagnetic actuation means (26, 30), respectively, and B) a single braking member test operation mode, in which one of the first and second actuating signals is supplied to the respective one of the first and second electromagnetic actuating means (26, 30), and an actuating signal for permanently releasing the respective of the first and second braking members (14, 16) is supplied to the other one of the first and second electromagnetic actuating means (26, 30).
