Structure of the operating instructions These operating instructions are designed to ensure safe working on and with the ZAsbc4 electronic brake control. The document contains safety instructions that must be complied with as well as information that is essential for fault-free operation of the device.
These instructions do not lay claim to completeness. In case of questions and problems, please consult our company technicians. Intended use The ZAsbc4 electronic brake control is a system component designed to provide contactor-less control of electromechanical motor brakes in passenger and goods elevator applications. The electronic brake control is available in two variants:...

The contactors normally used for switching the motor brakes can be replaced by the ZAsbc4. The ZAsbc4 is designed as a safety circuit and complies with EN 81-20 Section 5.9.2.2.2.3 a) 2).
Even if one brake circuit fails, the second brake circuit must retain sufficient braking action to delay, stop and hold the elevator car. The two redundant brake circuits must each be connected to an output on the ZAsbc4. "...
This can lead to uncontrolled movements of the elevator cabin. In addition, other monitoring functions are performed internally. If the ZAsbc4 detects an error, the brake circuits are locked and the following outputs are switched off: •...
To activate the "Safe switch-off (STO)" function of the ZAdyn frequency inverters, two coupling relays are integrated in the ZAsbc4, which must be controlled by the end of the safety chain. The relays K1 and K2 are controlled using the connections X-SC:SC_A and X-SC:SC_B.
Functional description ZAsbc4 Use of the ZAsbc4 with motor contactors When using motor contactors (frequency inverter without safe switch-off (STO)), the contactors are to be incorporated in such a way that the motor contactors are de-energised if the safety chain neutral conductor is interrupted by the contact SC_O.

Closing the brakes: The ZAdyn frequency inverter switches off the "MB brake" output. With this signal, the S1A, S1B inputs of the ZAsbc4 must be switched off without a delay. The S2 input of the ZAsbc4 must still remain set.
The ZAdyn frequency inverter switches off the "RB contactor" output. With this signal, the S2, SC_A, SC_B inputs of the ZAsbc4 must be switched off without a delay. When using motor contactors, the motor contactors are deactivated instead of the SC_A and SC_B inputs.
