2 Do you have any problems with workpiece suction? The Flow rate sensor detects workpieces lifted by vacuum that could not be detected by the pressure sensor. Made compatible with the separate type multi-channel flow rate sensor controller Used sensor head, operation method, and setting commands are made compatible with each other. Three sensor head types: - 00 to 00 m l /min (ANR) [-0. to 0. in /min], - to l /min (ANR) [-0.06 to 0.06 ft /min], and 0 to 0 l /min (ANR) [0 to 0. ft /min]. RS-C communication type and output type available Flow rate can be constantly monitored by RS-C or analog output. RS-C type: Flow rates in ASCII can be imported. Analog output type: Flow rates can be imported using analog voltage. Power supply, switch output Power supply, switch output Sensor head Separate type multi-channel Flow rate sensor controller No piping resistance effect To avoid the effects of piping resistance, there is no limit on the flow rate sensor head mounting position.

3 Safety precautions (-channel Flow Rate Sensor Controllers) Safety precautions specific to -channel Flow Rate Sensor Controllers are shown below. Be sure to read the material in the front of the General Personal Catalog regarding safety precautions other than those below. DANGER While the product is in operation, do not attempt to adjust the attached mechanisms (connecting and disconnecting the wiring connector, or attach or position the sensor head, etc.). Abnormal operations could result in injury. WARNING While the -channel Flow Rate Sensor Controller is in operation, do not apply an external magnetic field to the controller and sensor head. This could cause unintentional operation leading to damage to equipment or to personal injury. When wiring, be careful to ensure that the wiring polarity is correct. A wrong polarity could result in damage to the -channel Flow Rate Sensor Controller. CAUTION Always use the specified sensor head with this product. Use of an unspecified item could result in erratic operation. When handling the -channel Flow Rate Sensor Controller and sensor head, avoid hitting, dropping, or bumping with excessive force (9 m/s [0 G] or more). Even if not apparently damaged, the internal parts could be damaged, leading to erratic operation. Do not short the load. Switching on sensor output with a shorted load could cause damage to the -channel Flow Rate Sensor Controller due to overcurrent. Example of load shorting: Connecting the output lead wires for sensor output directly to the power supply. When mounting the fitting to the sensor head, the tightening torque should not exceed. N m [.8 in lbf]. In addition, when securing the sensor head, use an M screw and the tightening torque should not exceed 0.6 N m [. in lbf]. Excessive tightening could damage the sensor head, etc. Always switch off the power before connecting the sensor head and controller. Attempting to connect the sensor head with the power on could cause erratic operation in the controller due to surge voltage, etc. Handling Instructions and Precautions Wiring General precautions. If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.. In the case of noise generating equipment (switching regulator, inverter motor, etc.) being used in the vicinity of sensor mounting portion, connect the frame ground (F.G.) terminal of the equipment to an actual ground.. When wiring is completed, check that there is no error in the wiring connections. Other. Sensor head is designed for use with non-corrosive gas. It cannot be used for liquid or corrosive gas.. Use within the rated voltage range for power supply.. Do not use during the initial transient time (0. sec.) after the power supply is switched on.. Do not operate the keys with pointed or sharp objects.. When using window comparator mode in operations that capture repeated utilization of the reference flow rate, the guaranteed number of times may be exceeded in a short period of time. In such cases, use window comparator mode. 6. If using with window comparator mode, use FSU-S-D. 68 0_06

13 Setting guidelines CAUTION. Incorrect wiring to the sensor head, power/switch output, and communication/analog output cables creates the risk of damage to both the controller and sensor head. Confirm that wiring is correct before turning on power.. The conditions that were configured are saved as a record written to flash memory. Note that flash memory has a limited life, and the number of guaranteed writes is 0,000.. With window comparator mode, repeated reference flow rate import can cause the guaranteed number of flash memory writes to be exceeded within a short period. When this happens, use window comparator mode..
