Ue: operational voltage measured. Cos j: power factor. T0.95: time taken to reach 95% of nominal current. Notes The maximum values for the breaking capacity of the safety outputs in the various utilization categories are not fixed and depend on the power factor and on the switching frequency. The test definition for the breaking capacity and durability tables in the European standard EN uses different values for the power factor and the switching frequency. The power factor (cos j) in the breaking capacity table (0.3) is greater than that in the durability table (0.7). In the breaking capacity table, the switching frequency of the safety outputs is higher for the first 000 switching operations (60 per minute) than that for 00 to 6050 switching operations (6 per minute). Consequently, the maximum breaking capacity values determined using the breaking capacity table are lower than those in the durability table. 7

10 Operating principle, specifications Preventa safety relay modules types XPSAC, XPSAXE For Emergency stop and switch monitoring Operating principle Safety relay modules XPSAC and XPSAXE are used for monitoring Emergency stop circuits conforming to standards EN/ISO 3850 and EN/IEC and also meet the requirements for the electrical monitoring of switches in protection devices conforming to standard EN 088/ISO 49. They provide protection for both the machine operator and the machine by immediately stopping the dangerous movement on receipt of a stop instruction from the operator, or on detection of an anomaly in the safety circuit itself. To aid diagnostics, the modules have LEDs which provide information on the monitoring circuit status. Specifications The XPSAC module has 3 safety outputs and a solid-state output for signalling to the PLC. The XPSAXE module has 3 safety outputs and a relay output for signalling to the PLC.

14 Operating principle, specifications Preventa safety relay modules types XPSAV, XPSABV, XPSATE For Emergency stop and switch monitoring Operating principle Safety relay modules XPSAV, XPSABV and XPSATE are used for monitoring Emergency stop circuits conforming to standards EN/ISO 3850 and EN/IEC and also meet the requirements for the electrical monitoring of switches in protection devices conforming to standard EN 088 / ISO 49. They provide protection for both the machine operator and the machine by immediately stopping the dangerous movement on receipt of a stop instruction from the operator, or on detection of an anomaly in the safety circuit itself. Specifications Module type In addition to the stop category 0 instantaneous opening safety outputs (3 for XPSAV, 2 for XPSABV and 2 for XPSATE), the modules incorporate stop category time delay outputs (3 for XPSAV, for XPSABV and 3 for XPSATE) which allow for controlled deceleration of the motor components until a complete stop is achieved (for example, motor braking by variable speed drive). At the end of the preset delay, the supply is disconnected by opening the time delay output circuits. For module XPSAV, the time delay of the 3 output circuits is adjustable, in 5 preset values, between 0 and 300 seconds using selector buttons. For module XPSABV, the time delay of the output circuit is adjustable between 0.5 and 3 seconds or.5 and 30 seconds, depending on the model, using a selector switch. For module XPSATE, the time delay of the 3 output circuits is adjustable between 0 and 30 seconds using a 2-position selector switch. Module XPSAV also incorporates 3 solid-state signalling outputs for signalling to the process PLC. Module XPSATE incorporates 4 solid-state signalling outputs for signalling to the process PLC. To aid diagnostics, the modules have LEDs which provide information on the monitoring circuit status. The Start button monitoring function is configurable depending on the wiring.

24 Operating principle Preventa safety relay modules types XPSBA, XPSBCE, XPSBF For electrical monitoring of two-hand control stations Operating principle Two-hand control stations are designed to provide protection against hand injury. They require machine operators to keep their hands clear of the hazardous movement zone. The use of two-hand control is an individual protective measure, which can protect only one operator. Separate two-hand control stations must be provided for each operator in a multiple-worker environment. Safety relay modules XPSBA, BCE and BF for two-hand control stations comply with the requirements of European standard EN 574/ISO 385 for two-hand control systems. The control stations must be designed and installed such that they cannot be activated involuntarily or easily rendered inoperative. Depending on the application, the requirements of type C standards specific to the machinery involved must be met (additional personal protection methods may have to be considered). To initiate a hazardous movement, both operators (two-hand control pushbuttons) must be activated within an interval y 0.5 s (synchronous activation). If one of the two pushbuttons is released during a hazardous operation, the control sequence is cancelled. Resumption of the hazardous operation is possible only if both pushbuttons are returned to their initial position and reactivated within the required time interval. The control sequence does not occur if: Both two-hand control push buttons are pressed during a time period greater than 0.5 seconds, A short-circuit is present in a push button contact, The feedback loop is not closed at start-up. The safety distance between the control units and the hazardous zone must be sufficient that when only one operator is released, the hazardous zone cannot be reached before the hazardous movement has been completed or stopped. XPSBA This module is designed for use on lighter duty applications where a two-hand control function is desired, but where the safety category is B or (per EN 954-) and the two-hand control requirements meet Type III A (per EN 574/ISO 385). This module is not to be used for applications, such as presses, which require a Type III C module or where the application is not a category B or. For press applications, for applications in category 2, 3, or 4, or if application calls for a Type III C module, use XPSBCE or XPSBF module. XPSBCE and XPSBF These modules can be used on applications, such as presses, which require a Type III C module. The XPSBCE and XPSBF can be used for a two-hand control application, including presses and similar equipment. Specifications: page 23 page 25 Wiring diagrams: page 26 22
