Introduction 1.6 Product-specific information ESD guidelines ESD components are destroyed by voltage and energy far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged.

(see Chapter "Application (Page 23)"), and only in conjunction with equipment or components from other manufacturers which have been approved or recommended by Siemens. You must also ensure that suitable and reliable sensors are used (see Chapter "Basic versions (Page 24)" and "Configuring (Page 57)").

Introduction 1.6 Product-specific information Encoder NOTICE Use of encoders In order to achieve the highest possible SIL/PL when using encoders, 2-channel encoders (4 tracks: A, A/, B, B/) with defined failure response (high-impedance outputs) must be used. If such information cannot be found on the encoder manufacturer's data sheet, then the failure response data must be requested from the encoder manufacturer.
Page 17
Introduction 1.6 Product-specific information Figure 1-2 Dual-channel actuator wiring via one terminal Note To achieve SILCL 2/3 as per IEC 62061 or PL d/e as per EN ISO 13849‑1, a fault exclusion such as a short-circuit to P or M is required. This can, for example, be implemented within a control cabinet or by installing the connection cables in such a way that they are protected.
Siemens’ products and solutions undergo continuous development to make them more secure. Siemens strongly recommends that product updates are applied as soon as they are available and that the latest product versions are used. Use of product versions that are no longer supported, and failure to apply the latest updates may increase customer’s exposure to cyber...

Product description 3.2 Application Application The device is designed for use on machines and plants whose motions or moving parts can constitute a hazard to personnel or machinery. The device continuously carries out standstill monitoring (output circuit 13/14) and speed monitoring (output circuit 23/24).
Product description 3.3 Basic versions Basic versions 3TK2810-1 speed monitor The speed monitor is the main component of safety-related speed monitoring and is necessary in every application. The terminals and the RJ45 interface are used for the outputs, and for supplying the device with power and signals.
Page 25
Product description 3.3 Basic versions Evaluation is carried out in two diversely redundant microcontrollers using the applied pulse trains. The measured frequency is compared here with the specified speed limit for standstill, and with the limits for setup or automatic mode (depending on the operating mode). The speed limits for the individual operating modes can be adjusted by the user to optimally adapt the speed monitor to the most diverse applications and motor types.

Operation Times Start override time t The start override time is used, for example, to bridge the start time of a motor until it has reached a specific speed. If the parameterized min. setup or automatic speed is not reached within the parameterized start override time t , the device switches immediately to the safe state.
Page 48
Operation 7.1 Times To provide this verification, you must calculate the total response time of the application you have configured. Note Note that the results of calculating the response time affect the level of safety and affect the overall design of the system. Response time up to the switch-off procedure after expiry of the set start override time The maximum response time up to detection of a violation of the upper/lower limit depends on the selected parameters.
