PART NAMES AND FUNCTIONS 5 Cable length selector switch Normally set this switch to "3 m" (the lower position). When an optional extension cable (7 m) is added, set this switch to "10 m" (the upper position). (7 m cable: model OP20708) 6 Lock switch When this switch is set to LOCK (the lower position), any output adjustment keys (7) are disabled. 1 Sensor head cable connector 7 Output adjustment keys The functions are changed by adjusting the Mode selector switch position.
CONNECTIONS Referring to the following descriptions of terminals, complete connections before you turn the power ON. Analog voltage output (V) 8 Analog current Interference suppression output (mA) (CONTROL) (SYNC) 9 0V 10 11 Sensor head cable connector 9 Analog current output terminal: Analog current of 4 to 20 mA relative to full measuring range is output. A & B Interference suppression terminals: (See p.12.
CONNECTIONS HINTS ON CORRECT USE To make the EX-500(W) series comply with the EMC directive (CE marking), use the attached ferrite cores as shown in the illustration below. ■ Noise interference Sensor head Ferrite core (smaller one in the accessory) ZCAT1325-0530A (TDK) 20 M ax. 8 9 POWER 10 11 12 OVER 2 3 4 5 6 • Keep the wiring and connection cable away from high-voltage lines or power lines; otherwise noise may affect the performance of the EX-500(W).
INSTALLATION Controller The controller can be mounted to a DIN rail. When mounting or dismounting the controller, pull the claws located at the bottom of the controller in the direction shown by the arrows. Also, the controller can be mounted with screws by pulling out the fittings. ■ Mounting Nut tightening position Tighten the nut away from the tip of the metal case as shown on the right. 3mm min Torque values Tighten the nut according to the torque values given in the table below.
ADJUSTMENT Before starting measurements, adjust the analog output with an actual target using the following procedure. 3. Set the cable length selector switch according to the sensor head cable length. Connection 4. Set the lock switch to FREE (the upper position). 1. Connect a panel meter or voltmeter to the analog output terminal of the controller using a shielded cable. 2. Complete the connections and then turn the power ON.
ADJUSTMENT 3. Set the distance between the sensor head and the target to half the maximum measuring distance. Then press the <3> key (linearity compensation key) to check whether the output voltage is 2.5 V. Harf F.S.(Harf max. measuring distance) The LED lights. The LED goes out. Press the <3> key. Approx. 3 seconds after pressing the key. When current output is used . the output current is set to 12 mA. Hold the sensor head at half the maximum measuring distance until the LED of <3> key goes out.
MEASURING RANGE VS. ANALOG OUTPUT AUTO-ZERO/AUTO-SPAN FUNCTIONS Each sensor outputs an analog voltage (current) in proportion to the measuring distance. Auto-zero function EX-501(W)/008 EX-502(W)/008 Measuring range F.S. (Full Scale) =1 mm Measuring range F.S. (Full Scale) =2 mm Using the front panel key or by an external signal, the analog output voltage can be set to 0 V (analog output current to 4 mA) when the target is at any position within the measuring range.
AUTO-ZERO/AUTO-SPAN FUNCTIONS Example: With the EX-501(W), set the distance between the sensor head and the target to 0.2 mm. ■ Auto-zero adjustment range 6V 5V Auto-zero adjustment range When current output is used . the output current is set to 4 mA. Press the <3> key. 0 F.S. Ground terminal to √ terminal ➄. to -5 v * Even when the lock switch is set to LOCK (the lower position), the auto-zero function can be activated by an external signal.
AUTO-ZERO/AUTO-SPAN FUNCTIONS Auto-span function Using the auto-span function, the ratio of the analog output voltage relative to the measuring distance can be changed. This function is useful to measure targets having a small diameter or round surface because with these targets the input-to-output ratio is variable or is linear only to a limited range. Be sure to calibrate your sensor for the desired targets. 5V F.S.
INTERFERENCE SUPPRESSION FUNCTION CAUTION EX-500W only The terminals 0 - B for interference suppression function are indicated as blank terminals with the EX-500W series (compliant model with EMC directive of CE marking). These terminals can be used for the interference suppression function as shown below. However, please note that the EX-500W may not conform to EMC directive, if you use this function and these terminals.

TROUBLESHOOTING GUIDE CHARACTERISTICS If any trouble occurs with your EX-500(W) Series, check the following items. If the sensor does not work properly, contact your distributor or nearest KEYENCE office. ■ Output voltage for measuring targets of various sizes (Typical) EX-502(W)/EX-008 (Target: Aluminum A5052) • Securely connect the cable into the connector. Keep the sensor wiring away from high-voltage lines and power lines.
