Need help?Do you have a question about the Siemens Sirius 3SE660-BA Series and is the answer not in the manual?
The Siemens SIRIUS 3SE660.-.BA and 3SE6704-.BA magnetic monitoring system is designed for safety-oriented applications, complying with IEC 60947-5-3 and IEC 60529 standards. This system ensures safety functions as part of a complete plant or machine, typically comprising sensors, evaluation units, signaling devices, and safe shutdown concepts. The responsibility for ensuring the correct overall function lies with the manufacturer of the plant or machine.
The magnetic monitoring system operates by detecting the presence or absence of a coded magnetic actuator (3SE6704-.BA) in relation to a switching element (3SE660.-.BA). The system is only considered compliant with EN 60947-5-3 when the complete system, including the switching element, coded magnet, and a monitoring unit (e.g., 3TK284 electronic or AS-i Safe and SIMATIC S7300F), is used.
For the actuation of the 3SE660.-.BA switching elements, only the coded magnet 3SE6704-.BA can be used. The system requires a proper check of its operation with the connected monitoring unit. When the center marking of the magnet is within the depicted basic setting zone, the connected monitoring unit provides an enable signal. This ensures that the safety function is only activated when the magnet is in the correct position relative to the sensor.
The system includes safety contacts (S21-S22 and S13-S14) and signaling contacts (S31-S32). For the 3SE6606-3BA model, the S13-S14 contacts are designated as NO (normally open) for the safety evaluation input, and S21-S22 as NC (normally closed) for the safety evaluation input. The S31-S32 contacts are exclusively for signaling functions.
The devices are rated for an IP67 degree of protection, indicating high resistance to dust and water ingress, making them suitable for harsh industrial environments. They can operate within a temperature range of -25°C to +70°C.

Installation Requirements:
Adjustment: Adjustment of the system is crucial for correct operation and is recommended using the provided diagram. The operating distances specified refer to switches and magnets mounted opposite each other. Other arrangements are possible but may lead to different operating distances.
Actuation: For lateral actuation (e.g., sliding doors), the safety sensor should only be actuated from the side opposite to the cable outlet. This ensures proper functionality and prevents potential interference with the cable.
Connection: The connection diagrams illustrate the wiring for different models, including safety and signaling contacts. For instance, the 3SE6606-3BA model shows 1 NO and 2 NC contacts, with specific color codes for wiring (GY S13, GN S21, WH S31, PK S14, YE S22, BN S32). The monitoring units like 3TK2841 and 3TK2826 are used to evaluate the signals from the safety sensors, ensuring compliance with performance levels (PL e) according to DIN EN ISO 13849-1 and Safety Integrity Level (SIL3) according to EN 62061.
The manual emphasizes the importance of ensuring the correct overall function of the safety system, which is the responsibility of the plant or machine manufacturer. Before any work on the equipment, it is critical to switch off the power to prevent hazardous voltage and potential injury or death.
The robust design, indicated by the IP67 protection rating and high resistance to shock and vibration, suggests that the devices are built for durability and require minimal maintenance under normal operating conditions. However, regular checks of the proper operation with the connected monitoring unit are essential to maintain safety integrity. The manual serves as a reference for installation, dimensional drawings, and connection details, which are vital for troubleshooting and maintenance activities.
