Do not connect loads beyond the rated value to the safety outputs. Serious injury may occur due to loss of required safety functions. Do not use the Safety Mat with logics that the operation of the mat might turn ON the guarded equipment. Use the Safety Mat with logics by which safety outputs turn OFF in a hazardous state. Serious injury may occur due to loss of required safety functions. Wire the Safety Mat properly so that supply voltages or voltages for loads do NOT touch the safety inputs accidentally or unintentionally. Serious injury may occur due to loss of required safety functions. Do not use a Safety Mat to detect children as it does not support child detection. To use a Safety Mat for the purpose of entry detection, secure the following safety distance until a person reaches a hazardous area by walking on the mat. Otherwise, the machine may not stop before the person reaches the hazardous area, causing injury. Precautions for Safe Use • Turn OFF the power supply before wiring. Also, do not touch any terminals (current-carrying parts) while the power is ON. Doing so may result in electric shock. • Do not perform wiring when there is a risk of lightning. Doing so may result in electric shock. • Apply properly specified voltages to the Safety Mat inputs. Applying inappropriate voltages cause the Safety Mat to fail to perform its specified function, which leads to the loss of safety functions or damages to the Safety Mat. • Use a power supply of the specified voltage. Do not use power supplies with large ripples or power supplies that intermittently generate incorrect voltages. • Do not use the Safety Mat for a load that exceeds the Safety Mat's switching capacity (contact voltage, contact current) or other contact ratings. Doing so will reduce the specified performance, causing insulation failure, contact welding, and contact failure, and the Safety Mat may be damaged or burnt. • The durability of the Safety Mat depends greatly on the switching conditions. Confirm operation under the actual conditions in which the Safety Mat will be used. Make sure the number of switching operations is within the permissible range. If a Safety Mat is used after performance has deteriorated, it may result in insulation failure between circuits and burning of the Safety Mat itself. • Do not use the Safety Mat where flammable gases or explosive gases may be present. Doing so may cause combustion or explosion due to Relay heating or arcing during switching. • Do not drop or disassemble the Safety Mat. Doing so may reduce the product characteristics and may result in damage, electric shock, or burning. • To prevent short-circuit or ground failure of the load, connect protection elements such as fuses. Not doing so may damage or burn the load. • When installing trims, be careful not to get injured by the edge of the trim, etc. Calculation of the Minimum Safety Distance The EN999 standards provide the following formula to calculate the minimum safety distance for floor-installed Safety Mats: S = (1,600 x T) + 1,200 mm In this equation, S is the minimum safety distance (unit: mm), the term 1,600 represents a standard approach speed of 1,600 mm/s, T is the overall stop time required for the machinery to stop, and the term 1,200 mm represents the length of a step and the length of an arm. The overall stop time is comprised of two components: T = t1 + t2 t1 : Maximum response time from the activation of the detection device to the point that the control device's output goes OFF (30 ms for these Safety Mats). t2 : Response time of the machinery, i.e., the time required to stop the machine or remove the risk after receiving the output signal from the Safety Mat System. The worst case scenario for the response time of the machinery (t2) must be used in the formula. The actual response time depends on various factors such as the machinery being used, the operating mode, the product being processed, and the point in the control cycle at which the stop signal is received. If there are other factors that may affect the response time, such as brake wear, these factors must be taken into account as well. Example Calculation In this example, the Safety Mats are used with machinery that has a measured worst-case response time of 0.485 s. T = t1 + t2 = 30 ms + 485 ms = 515 ms = 0.515 s S = (1,600 x 0.515) + 1,200 mm = 824 + 1,200 mm = 2,024 mm Consequently, the Safety Mat must be installed at a minimum distance of 2,024 mm from the danger source. Note: 1. Read the Instruction Sheet included with the Safety Mat System thoroughly for details on designing and installing the Safety Mat System to provide the minimum safety distance mentioned above. 2. The Safety Mat's Ramp Trim and Molded Corner are not considered part of the Safety Mat's detecting area. Do not include the Ramp Trim and Molded Corner in the safety distance. 10 UM/MC3 Precautions for Correct Use Make sure to use the Safety Mat UM series in combination with the Safety Mat Controller MC series. Use of air valve 1. After installing a mat, loose the air valve on the surface of the mat for 30 seconds or more in order to make the internal air pressure equal to external air pressure.Then, close the air valve. 2. Turn the air valve with a torque at 1.5 N·m or less. 3. Do not store or use the the mat with loose air valve. It may allow water penetration. Handle with care 1. Do not drop the Safety Mat to the ground or expose to excessive vibration or mechanical shocks. The Safety Mat may be damaged and may not function properly. 2. Do not apply loads on a certain location of the Safety Mat for a long period of time. It may damage the Safety Mat. 3. Do not use the Safety Mat submerged in water or in locations continuously subject to splashes of water. 4. Store the Safety Mat in a vertical (standing) position prior to install so that loads are not applied to the Safety Mat. Mounting of the Safety Mat 1. Use- dedicated trims to secure the circumference of the Safety Mat for installation. 2. Do not install the Safety Mat on an environment with a projection. Install it on a flat surface. 3. Do not pull the cables to lift or move the Safety Mat. 4. Do not use the Safety Mat with a cover on it. Solvents Adhesion of solvent such as alcohol, thinner, trichloroethane or gasoline on the product should be avoided. Such solvents make the marking on the Safety Mat illegible and cause deterioration of parts. Others This is a Class A product (Product in industrial setting). Use of the product in residential setting may cause radio disturbance. In such case, take appropriate measures. Storage conditions of the Safety Mat Do not store in such conditions stated below. 1. In direct sunlight 2. At ambient temperatures out of the range of -37 to 66°C. 3. At air pressure out of the range of 86 to 106 kPa. 4. In corrosive or combustible gases 5. With vibration or mechanical shocks out of the rated values. 6. Under splashing of oil, chemicals 7. In the atmosphere containing dust, saline or metal powder. The Safety Mat may be damaged and may not function properly. Safety Category Certification has been obtained for EN 954-1 Safety Category 3 for a system consisting of only Safety Mats and the Safety Controller. A separate safety controller is required to achieve a category 3 safety circuit if external safety relays or magnetic contactors are connected. Storage conditions of the Safety Mat Controller Do not store in such conditions stated below. 1. In direct sunlight 2. At ambient temperatures out of the range of 0 to 55°C. 3. At relative humidity out of the range of 90%RH or under such temperature change that causes condensation. 4. At air pressure out of the range of 86 to 106 kPa. 5. In corrosive or combustible gases 6. With vibration or mechanical shocks out of the rated values. 7. Under splashing of water, oil, chemicals 8. In the atmosphere containing dust, saline or metal powder. The Safety Mat Controller may be damaged and may not function properly. Wiring of the Safety Mat Controller 1. Use the following to wire to the Safety Mat Controller • Stranded wire (Flexible wire): 0.2 to 2.5 mm2 • Solid wire: 0.2 to 2.5 mm2 • Strip the cover of wire no longer than 7 mm. 2. Tighten each screw with a specified torque of 0.4 to 0.5 N·m, or the Safety Mat Controller may malfunction or generate heat. 3. Ground the negative side of the power supply. A controller with the positive side grounding will not work. Mounting of multiple Safety Mat Controllers 1. In closely contacted mounting, the rated carry current is 3 A. Use at 3 A or less voltage. 2. When applying more than 3A , place the mats farther than 25 mm from the nearest MC3. Mounting of the Safety Mat Controller to DIN rails Use end plates (PFP-M: sold separately) on both ends of MC3. 11 Read and Understand This Catal og Please read and understand this catalog before purchasing the products.
