4 Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable. In no event will OE Max Controls be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.ì The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, OE Max Controls cannot assume responsibility or liability for actual use based on the examples and diagrams. No patent liability is assumed by OE Max Controls with respect to use of information, circuits, equipment, or software described in this manual. Reproduction of the contents of this manual, in whole or in part, without written permission of OE Max Controls is prohibited. Throughout this manual we use notes to make you aware of safety considerations. WARNING Identifies information about practices or circumstances which may lead to serious personal injury or death, property damage, or economic loss. IMPORTANT Identifies information that is critical for successful application and understanding of the product. ATTENTION Identifies information about practices or circumstances that can lead to minor personal injury, property damage, economic loss, or product malfunction. However, depending on situation, failure to follow the directions accompanying this symbol may also lead to serious consequences. 4

5 Safety Instructions Precautions regarding system design In certain applications, malfunction may occur for the following reasons: The timing difference between opening and closing of the PLC power supply, the I/O modules and power equipment An operation time lag when a momentary power failure occurs Abnormality in the PLC, external power supply, or other devices In order to prevent a malfunction resulting in system shutdown choose the adequate safety measures listed in the following: Interlock circuits on the outside of PLC When a motor clockwise/counter-clockwise operation is controlled, provide an interlock circuit that prevents clockwise and counter-clockwise signals from inputting into the motor at the same time. Emergency stop circuits on the outside of PLC Install the emergency stop circuits outside the PLC to stop the power supply of the output device. Start PLC after other devices (Start up sequence) The PLC should be operated after all of the I/O devices and the power equipments are energized. Switch to RUN mode after the start of PLC. Use a timer circuit to delay the start of PLC. Watchdog timer The watchdog timer is a program error and hardware error detection timer. It goes On when the scan time exceeds 640 ms. When the watchdog timer is activated, at the same time the ALARM LED lights, the ALARM contacts on the power supply module turn to On, all output modules are turned Off and the module is put in halted state. (The system is in a non-processing state that includes communications with programming tools as well.) 5

7 Installation Location Be sure to maintain a sufficient distance from wiring ducts, and other machines below and above the module for proper ventilation. Do not install the modules stacked up or horizontally. Doing so will prevent proper cooling of the module and cause overheating inside the PLC (programmable controller). Do not install the module above devices which generate heat such as heaters, transistors or large scale resistors. In order to eliminate any effects from noise emission, power wires and electromagnetic devices should be kept at least 100 mm away from the surfaces of the module. When installing the module behind the doors of the operation panel, be especially careful to maintain these distances. Duct Min. 50 mm 100 mm or more Duct Min. 50 mm Other devide Space for Programming Tool Connection Leave a space of at least 180 mm from the mounting surface for programming tool connections and wiring. Programming Cable Approx. 110 mm Approx. 180 mm 7

8 Avoid installing the module in the following conditions Ambient temperature outside the range of 0 to 55 C Ambient humidity outside the range of 30 to 85% RH Sudden temperature changes causing condensation Inflammable or corrosive gases Excessive airborne dust, metal particles, salinity Benzene, thinner, alcohol, other organic solvents or strong alkaline solutions such as ammonia or caustic soda Excessive vibration or shock Direct sunlight Location near high-tension wires, high-voltage devices, power cables, power devices, or other devices with generate large power surges or electronic fields when starting and stopping (esp. if within 100 mm) Proper compressed connection terminal Circular type terminal (O type Lug) Circular type terminal with insulation resistance Open type terminal (Y type Lug) 8

9 Mounting/Dismounting Module Mounting 1. Insert the module holding projector of the module into the module holding groove on the backplane. Dismounting 1. Unfasten the screw that holds the module in place using a screwdriver. 2. Push the top of the module toward the backplane until it is clamped in place. 2. Hold on pressing the locking button on the edge of the top side of the module, and pull the module from the backplane. Locking button 3. Ensure that the module is in place onto the backplane, and then fasten the screw using a screwdriver. Screwdriver 9

10 Power Supply Module Wiring NX70 power supply module Use 2mm 2 twisted pair cable or larger Power Breaker Use an isolation transformer when effects from noise are great. FUSE USE ONLY 250V 1.5A VAC Use 2mm 2 cable or larger for grounding FRAME GROUND 24V DC 0.3A OUTPUT VAC ATTENTION Control power (24V) 24V can be supplied to an I/O Module. Must avoid parallel connections with other 24V power supply modules or with other power supply modules. The power supply voltage connected to the power supply module must be within allowable limits. Catalog number NX70-POWER1 NX70-POWER2 Rated input voltage Allowable voltage Range 110 to 220V ac 85 to 264V ac Terminal for the power supply module The terminal screw M3.5 is recommended. The compressed connection terminal is recommended for the wiring. Open type terminal Circular type terminal 7.0mm or less 7.0mm or less Φ 3.7 ~ Φ 4.3 Use 2mm 2 twisted pair cable or larger Use power supply wire that is thicker than 2mm 2 to minimize voltage drops. Use twisted pair cable to minimize noise effects. 10

11 Power Supply System Use separate wiring systems for the PLC module, I/O module, and power supply module as shown in the following diagram. Power equipment External I/O device isolation transformer PLC isolation transformer Use isolation transformer for noisy environments Use a low noise power supply. Use an isolation transformer to reduce the noise as illustrated above. Grounding Ground the PLC for noisy environments Connected to the metal part of backplane, the frame ground terminal is connected to a solid earth ground. Use ground wires with a minimum of 2mm 2 and the triple grounding connection which has a resistance of less than 100 Ω. The point of grounding should be as close to the PLC as possible and the ground wire should be as short as possible. If two devices share a single ground point, it may produce an adverse effect. Always use an exclusive ground for each devic PLC Other devices such as the AC drive PLC Other devices such as the AC drive 11
