- Page 2 These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “CAUTION” “WARNING” or “DANGER”. To ensure safety, be sure to observe ISO 4414 and other safety practices. ■ Definition Label Meaning of label △ WARNING Operator error could result in serious injury or loss of life. ！ △ CAUTION Operator error could result in injury or equipment damage. ！ △ WARNING ！ ① The compatibility of the product is the responsibility of the person who designs the equipment or decides its specifications. Since the product specified here is used under various operating conditions, its compatibility with specific equipment must be decided by the person who designs the ...
- Page 3 Precautions for Handling △ CAUTION ！ If the power supply for this product is cut due to a power failure during controlling, the output of the secondary side is held temporarily. If the secondary side output is released to the atmosphere, air will keep coming out. Handle with care. If the pressure supply is cut while power is supplied, the built in solenoid valve will keep operating and may make a buzzing noise. This may affect the life of the solenoid valve. Be sure to cut the power supply to the product when cutting the pressure supply. The product is adjusted to each specification at the time of shipment from the factory. Avoid unnecessary disassembly or removal of parts, as this may cause failure. ―3― ...
- Page 4 △ CAUTION ！ Take the following measures against malfunction due to noise. １） I nstall a line filter in the AC power supply line to remove noise. ２） S eparate the signal lines from any intense electric field such as motor lines and power transmission lines as far as possible so as not to be affected by noise. ３） F or inductive loads such as solenoid valves and relays, make sure to take measures against load surge. ４） ...
- Page 5 Wiring and LED display △ CAUTION ！ ① Incorrect wiring may lead to breakage. ② Select a DC power supply with adequate capacity with low ripple. ③ Insert/pull out the connector after cutting the power supply. ④ The right angle cable connector does not rotate. Do not rotate it. ■ ITV connector pin assignment Wire color Item Pin assignment (Note 1) １．+24[V] Brown ２．N.C.

- Page 6 Select a DC power supply with adequate capacity with low ripple. Ex. : Class 2 voltage source. UL1310 compliant. For communication master (PLC), we recommend using a product for Profibus communication with SELV circuit which is compliant to IEC 60950-1, electrical safety standard. ■ LED indication Item Lights up Goes off RUN Lights when the power is turned on (Green) Light off when the power is cut DIA Lights when diagnostic error occurs (Red) Internal operation is normal BF Lights when PROFIBUS communication error PROFIBUS communication is occurs (Red) normal Mounting and Installation ■ Installation Direct mounting When the product is mounted directly onto the panel or device, use screws ...
- Page 7 Switch setting ■ Safety Instructions for Setting Turn off the power supply while setting the switch. ・ If there is foreign matter or water droplets around the switch cover, clean it off before opening the cover. ・ Refer to the drawing below for the setting at the time of shipment from the factory. Confirm the condition of switches before use and reset if necessary. ■ Setting procedure ①Loosen the screw(s) of the switch cover. ②Open the cover from the bottom upwards (See drawing on the right) ③Set switch, referring to the setting ９０° procedure below. ④After setting the switch, tighten the switch cover in the reverse order of the above procedure. ...
- Page 8 Pressure setting and output monitoring Pressure can be set by sending the input data, in which F.S. consists of 12 bits, to the E/P regulator through master PLC(inputting target value to 0 area). <Input data formula> “Set pressure”/“F.S. pressure range” x 4095 The value obtained by this formula is converted to a hexadecimal number for sending. EX.) To set pressure at 0.3MPa by ITV203*(for 0.5MPa type) (0.3MPa/0.5MPa)×4095＝2457（DEC）＝999(HEX) 0.3MPa of pressure is set by sending input data of “999” to the electromagnetic ...
