Span Adj. Base Socket ■ MODEL NO. Confirm Model No. marking on the product to be exactly what you ordered. ■ INSTRUCTION MANUAL This manual describes necessary points of caution when you use this product, including installation, connection and basic maintenance procedures. INSTALLATION Refer to “EXTERNAL DIMENSIONS.” LIGHTNING SURGE PROTECTION POINTS OF CAUTION ■ POWER INPUT RATING & OPERATIONAL RANGE • Locate the power input rating marked on the product and confirm its operational range as indicated below: AC power: Rating ±10%, 50/60 ±2 Hz, approx. 2VA DC power: Rating ±10%, approx. 2W M-System offers a series of lightning surge protector for protection against induced lightning surges. Please contact M-System to choose appropriate models. ■ GENERAL PRECAUTIONS • Before you remove the unit from its base socket or mount it, turn off the power supply and input signal for safety. ■ ENVIRONMENT • Indoor use. • When heavy dust or metal particles are present in the air, install the unit inside proper housing with sufficient ventilation. • Do not install the unit where it is subjected to continuous vibration. Do not subject the unit to physical impact. • Environmental temperature must be within -5 to +60°C (23 to 140°F) with relative humidity within 30 to 90% RH in order to ensure adequate life span and operation. ■ WIRING • Do not install cables close to noise sources (relay drive cable, high frequency line, etc.). • Do not bind these cables together with those in which noises are present. Do not install them in the same duct. ■ AND .... • The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet. 5-2-55, Minamitsumori, Nishinari-ku, Osaka 557-0063 JAPAN Phone: +81(6)6659-8201 Fax: +81(6)6659-8510 E-mail: [email protected] EM-2411 Rev.5 P. 1 / 2 PV TERMINAL CONNECTIONS Connect the unit as in the diagram below. ■ EXTERNAL DIMENSIONS unit: mm (inch) 2–5 (.20) dia.

For matching the signal to a receiving instrument or in case of regular calibration, adjust the output as explained in the following. ■ HOW TO CALIBRATE THE OUTPUT SIGNAL Use a signal source and measuring instruments of sufficient accuracy level. Turn the power supply on and warm up for more than 10 minutes. 1) ZERO: Apply 0% input and adjust output to 0%. WIRING INSTRUCTIONS ■ SCREW TERMINAL Torque: 0.8 N·m 2) SPAN: Apply 100% input and adjust output to 100%. 3) Check ZERO adjustment again with 0% input. 4) When ZERO value is changed, repeat the above procedure 1) – 3). PIPING The pneumatic inlet is female screwed of Rc 1/4” (1/4” NPT optional with a fitting). Tightening torque is at the maximum of 12 N·m. Check that there is no air leak at the connection after sealing it. CHECKING 1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram. 2) Power input voltage: Check voltage across the terminal 1 – 2 with a multimeter. 3) Input: Check that there is no air leak at the pneumatic connection. MAINTENANCE Regular calibration procedure is explained below: ■ CALIBRATION Warm up the unit for at least 10 minutes. Apply 0%, 25%, 50%, 75% and 100% input signal. Check that the output signal for the respective input signal remains within accuracy described in the data sheet. When the output is out of tolerance, recalibrate the unit according to the “ADJUSTMENT PROCEDURE” explained earlier. 4) Output: Check that the load resistance meets the described specifications. 5-2-55, Minamitsumori, Nishinari-ku, Osaka 557-0063 JAPAN Phone: +81(6)6659-8201 Fax: +81(6)6659-8510 E-mail: [email protected] EM-2411 Rev.5 P. 2 / 2 ">
