这些产品的安全输入被描述为常闭（N.C.），即防护装置关闭、致动器就位（如相关）以及机器能够启动。必须避免受到超过IEC 60068第2-6/7部分规定的冲击和/或振动。遵守建议的检查和维护说明是保修的一部分。有重伤的危险。误用会导致故障。•只有经过授权和培训的人员才能启动、组装、安装、操作或改装设备。•安装必须符合这些说明。•请勿破坏、篡改、移除或绕过此装置。在手动监控复位模式下，需要并监控复位电路（S33-S34）的信号变化。如果在复位电路闭合时，安全输入保持打开，则会发生复位故障。
功能描述
电源通电且安全电路关闭后，装置启用。PWR状态指示灯亮起。有效的复位操作激活安全输出。输出的CH1和CH2状态指示灯亮起。根据安全功能的要求，如果发生任何故障，安全输出将在规定的响应时间内断电。故障检测如果发生故障，内部继电器电路会强制关闭安全输出。一个或两个输出状态指示灯可能会熄灭。PWR状态指示灯会闪烁。清除故障并循环安全输入以重新启用设备。向安全继电器循环供电也可以清除故障状态。安全输入可以是单通道或双通道。根据接线输入，启用或禁用输入的交叉回路监控。您可以对4线连接（S11-S12、S21-S22）中的2通道安全输入启用交叉回路监测。对于单通道输入、三线连接中的双通道输入和24V DC信号，禁用交叉回路监控。对于外部24V DC信号，负极必须连接至S21。复位•复位模式-该装置具有自动/手动启动（MSR127T/TP安全继电器）和手动监测复位（MSR128R/RP安全继电器）。只有当反馈电路闭合时，才能操作有效的启动/复位。受控致动器的反馈触点与启动/复位电路（S12-S34）串联。•T-自动/手动启动在自动/手动起动模式下，复位电路S12-S34不受信号变化的监控（无边缘检测）。复位电路可以在安全输入闭合之前或之后闭合。一旦安全输入关闭且复位电路关闭，该装置即激活。如果在通电期间安全输入和复位电路同时闭合，则装置立即激活
Summary of Changes
This publication contains the following new or updated information. This list includes substantive updates only and is not intended to reflect all changes. Safety This device is intended to be part of the safety-related control system of a machine. Safety Notes Before installation, perform a risk assessment to determine whether the specifications of this device are suitable for all foreseeable operational and environmental characteristics of the machine to which it is to be fitted. At regular intervals during the life of the machine, check whether the characteristics foreseen remain valid.Rockwell Automation cannot accept responsibility for failure of this device if the procedures given in these instructions are not followed or if it is used outside the recommended specifications in these instructions
The safety inputs of these products are described as normally closed (N.C.), that is, with the guard closed, the actuator in place (where relevant) and the machine able to be started. Exposure to shock and/or vibration in excess of what is stated in IEC 60068 part: 2-6/7 must be avoided. Adherence to the recommended inspection and maintenance instructions forms part of the warranty.Danger of serious injuries. Misuse can result in malfunction. • Only authorized and trained personnel must start up, assemble, install, manipulate, or retrofit the device. • Installation must be in accordance with these instructions. • Do not defeat, tamper, remove, or bypass this unit.In Manual Monitored Reset mode, a signal change of the reset circuit (S33-S34) is required and monitored. A reset fault occurs if the safety inputs remain open while the reset circuit is closed.
Functional Description
The unit is enabled once the supply is powered up and the safety circuits are closed. The PWR status indicator is on. A valid reset operation activates the safety outputs. The CH1 and CH2 status indicators of the output illuminate. At the demand of the safety function and if any fault occurs, the safety outputs de-energize within the specified response time. Fault Detection If a fault occurs, the internal relay circuit forces the safety outputs off. One or both output status indicators can be off. The PWR status indicator can flash. Remove the fault and cycle the safety input to re-enable the device. Cycling power to the safety relay can also clear the fault condition.The safety input can be single-channel or dual-channel. According to the wiring inputs, cross-loop monitoring of the inputs is enabled or disabled. You can enable cross-loop monitoring for 2-channel safety inputs in 4-wire connection (S11-S12, S21-S22). Cross-loop monitoring is disabled for single-channel inputs, dual-channel inputs in 3-wire connection, and 24V DC signals. For external 24V DC signals, the negative pole must connect to S21.Reset • Reset modes — The unit is available with automatic/manual start (MSR127T/TP safety relay) and manual monitored reset (MSR127R/RP safety relay). A valid start/reset can only be operated if the feedback circuit is closed. Feedback contacts of controlled actuators are connected in series with the start/reset circuit (S12-S34). • T - Automatic/manual Start In Automatic/Manual Start mode, the reset circuit S12-S34 is not monitored against signal changes (no edge detection). The reset circuit can close before or after the safety inputs are closed. The unit is active once the safety inputs close and the reset circuit are closed. If the safety inputs and reset circuit are concurrently closed during power-up, the unit activates immediately
