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. POINTS OF CAUTION ■ CONFORMITY WITH UL •�This equipment is suitable for use in a Pollution Degree 2 environment. •�This equipment is to be used with the maximum operat- ing voltage 30 V rms and 42.4 V peak or 60 V DC. •�The equipment musts be mounted inside a suitable fire enclosure. •�Operating temperature: -40 to +55°C (-40 to +131°F) •�Altitude up to 2000 meters. ■ CONFORMITY WITH EU DIRECTIVES •�Functional insulation is maintained between the input and output. •�The input voltage across the terminals must be 70 V or less. •�The equipment must be mounted inside a panel. •�Insert noise filters for the power source, input and output connected to the unit. COSEL Model NAC-04-472, TDK Model ZCAT 3035-1330 or equivalent is recommended. •�The actual installation environments such as panel con- figurations, connected devices, connected wires, may af- fect the protection level of this unit when it is integrated in a panel system. The user may have to review the CE requirements in regard to the whole system and employ additional protective measures to ensure the CE conform- ity. •�Install lightning surge protectors for those wires connect- ed to remote locations. ■ GENERAL PRECAUTION •�Before you remove the unit 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 -40 to +85°C (-40 to +185°F) with relative humidity within 0 to 95% RH in order to ensure adequate life span and operation. •�Be sure that the ventilation slits are not covered with ca- bles, etc. ■ 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 sup- plied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.

Stranded: 0.2 to 2.5 mm2 (Tinning wire ends may cause contact failure and therefore is not recom- mended.) Ferruled: 0.2 to 1.5 mm2 (0.55 to 1.35 dia.) The following Phoenix Contact terminals are recommended: AI 0,25-8YE 0.2 to 0.25 mm2 AI 0,34-8TQ 0.25 to 0.34 mm2 AI 0,5-8WH 0.34 to 0.5 mm2 AI 0,75-8GY 0.5 to 0.75 mm2 AI 1,0-8RD 0.75 to 1.0 mm2 AI 1,5-8BK 1.0 to 1.5 mm2 •�Expose wire conductors by 8 mm (0.31”). 8 mm 8 mm 4 mm dia. max. 4 mm dia. max. Wire exposure Recommended ferruled wire CHECKING 1) Terminal wiring: Check that all cables are correctly con- nected according to the connection diagram. 2) Input: Check that the input voltage is within 0 – 100% of full-scale. 3) Output: Check that the load is within the permissible limit including wiring resistance. Load Resistance (Ω) = Supply Voltage (V) – 12 (V) 0.02 (A) (including leadwire resistance) 4) When you check the output signal, connect an ammeter of which the internal resistance is of 10 Ω max. to the monitor terminals. ADJUSTMENT PROCEDURE This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any cali- bration. 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%. 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 proce- dure 1) – 3). 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 accu- racy described in the data sheet. When the output is out of tolerance, recalibrate the unit according to the “ADJUST- MENT PROCEDURE” explained earlier. LIGHTNING SURGE PROTECTION M-System offers a series of lightning surge protector for protection against induced lightning surges. Please contact M-System to choose appropriate models.
