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
