PFM7##-TFK27-A Safety Instructions (Continued) Installation Caution Safety Instructions This manual contains essential information for the protection of users and others from possible injury and/or equipment damage. •Read this manual before using the product, to ensure correct handling, and read the manuals of related apparatus before use. •Keep this manual in a safe place for future reference. •These instructions indicate the level of potential hazard by label of "Caution", "Warning" or "Danger", followed by important safety information which must be carefully followed. •To ensure safety of personnel and equipment the safety instructions in this manual and the product catalogue must be observed, along with other relevant safety practices. Caution CAUTION indicates a hazard with a low level of risk which, if not avoided, could result in minor or moderate injury. Warning WARNING indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury. Danger •Do not touch the terminals and connectors while the power is on. Otherwise electric shock, malfunction or damage to the product can result. •After maintenance is complete, perform appropriate functional inspections and leak tests. Stop operation if the equipment does not function properly or there is a leakage of fluid. When leakage occurs from parts other than the piping, the product is faulty. Disconnect the power supply and stop the fluid supply. Do not apply fluid under leaking conditions. Safety cannot be assured in the case of unexpected malfunction. Panel mounting •Insert Panel Mount Adapter B (supplied as an accessory) into Section A of Panel Mount Adapter A. Push Panel Mount Adapter B from behind till the display is fixed onto the panel. The pin of Panel Mount Adapter B engages the notched part of Panel Adapter C to fix the display. •The switch can be mounted on a panel with a thickness of 1 to 3.2 mm. •See the illustration below for panel cut out dimensions. Section C A 24 +0.5 0 Installation & Maintenance Manual Digital Flow Switch Series PFM7 Installation (Continued) NOTE •The direct current power supply to be used should be UL approved as follows: Circuit (class 2) which is of maximum 30 Vrms (42.4 V peak), with UL 1310 class 2 power supply unit or UL 1585 class 2 transformer. •The Flow switch is a approved product only if it has a mark on the body.

This product is class A equipment that is intended for use in an industrial environment. There may be potential difficulties in ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbances. •Do not disassemble, modify (including changing the printed circuit board) or repair. An injury or failure can result. •Do not operate the product outside of the specifications. Do not use for flammable or harmful fluids. Fire, malfunction, or damage to the product can result. Verify the specifications before use. •Do not operate in an atmosphere containing flammable or explosive gases. Fire or an explosion can result. This product is not designed to be explosion proof. •Do not use the product in a place where static electricity is a problem. Otherwise it can cause failure or malfunction of the system. •If using the product in an interlocking circuit: •Provide a double interlocking system, for example a mechanical system •Check the product regularly for proper operation Otherwise malfunction can result, causing an accident. •The following instructions must be followed during maintenance: •Turn off the power supply •Stop the air supply, exhaust the residual pressure and verify that the air is released before performing maintenance. Otherwise an injury can be caused. Nominal size of screws Rc1/8 Rc1/4 Model Indication and How to Order DANGER indicates a hazard with a high level of risk which, if not avoided, will result in death or serious injury. Warning Piping •Ensure tightening torque is correct when installing piping. •Refer to the following table for the appropriate torque values. •Hold the metal part with a spanner when piping.

Press this button to change to the bottom display mode. button (SET): Press this button to change to each mode and to select a set value. Reset: Press the and buttons simultaneously to start reset function. This is to clear the condition when an abnormality occurs. Body: Product itself. Flow adjustment valve: Orifice mechanism to adjust the flow. Piping port: Connection port for piping. Knurl: Used to lock the flow adjustment valve. Through hole: Used to mount the product on a DIN rail or a panel directly. DIN rail mounting •The tightening torque for DIN rail mounting screws and joint screws should be 0.4±0.05 Nm. Wiring Connection •Make connection after turning the power off. •Use a separate route when installing wire. Malfunction stemming from noise may occur if wire is installed in the same route as that of power or high-voltage cable. •Be sure to ground terminal FG when using a switching regulator obtained on the market. If analogue output is performed connecting to a switching regulator obtained on the market, switching noise will be superimposed and product specification can no longer be met. This can be prevented by inserting a noise filter, such as a line noise filter and a ferrite element, between the switching regulator and the pressure switch, or by using a series power supply instead of a switching regulator. Connector Connecting/Disconnecting •When connecting the connector, insert it straight onto the pin holding the lever and connector body between fingers and lock the connector by pushing the lever claw into the square groove in the body of the switch. •When disconnecting the connector, push down the lever by thumb to disengage the lever claw from the square groove. Then pull the connector straight out. Body of switch Through hole Bracket Joint screw DIN rail mounting bracket Note) DIN rail mounting is not suitable for models with port type F02: G1/4.

Zero clear of indication Indication is reset to zero when and buttons are pressed simultaneously for 1 second. For initial use, implementation of zero clear is recommended. Set ON and OFF points of the Flow switch. Switch operation When a flow rate exceeds a setting point, the switch will be turned on. When the flow rate falls below the setting point by hysteresis or more, the switch will be turned off. The switch is adjusted such that it will be turned on with the center point of a flow rate setting range for each product specification.

Maintenance How to reset the product after power cut or de-energizing The setting of the product will be retained as it was before a power cut or de-energizing. The output condition is also basically recovered to that before a power cut or de-energizing, but may change depending on the operating environment. Therefore, check the safety of the whole facility before operating the product. Switch ON Switch OFF Time [s] <How to perform> *: The Product will also output during setting. 1. Press the button once in the measurement mode. 2. [P_1] or [n_1] and the set value are displayed alternately. Normal output Reversed output Displays in turn Setting functions Default setting At the time of shipment, the settings are performed as follows. If the setting is acceptable, keep it for use. Caution for handling When the setting is changed, since the different setting item appears in order depending on how many times the button is pressed, confirm the item which needs to be set appears to prevent undesired settings. Contact Error Indication Function This function is to display error location and content when a problem or an error has occured. Error Name Flow error Overcurrent error Error Display Error type Troubleshooting Flow exceeds the upper limit of the flow display range. Reduce the flow. 5% or more flow in the reverse direction. Direct the flow to the proper direction. Load current of the switch output (OUT1) exceeds 80 mA. Load current of the switch output (OUT2) exceeds 80 mA. Turn off the power supply and eliminate the cause of excess current. Then supply the power again. AUSTRIA BELGIUM CZECH REP.
