Series VP Specific Product Precautions 4 Be sure to read before handling. Refer to SMC website for Safety Instructions and 3/4/5 Port Solenoid Valves Precautions. Caution . Please connect correctly the lead wires to + (positive) and . (negative) indications on the connector. (For non-polar type, the lead wires can be connected to either one.) . When the valve with polarity protection diode is used, the voltage will drop by approx. 1 V. Therefore, pay attention to the allowable voltage fluctuation (For details, refer to the solenoid specification of each type of valve). . Solenoids, whose lead wires have been pre-wired: + (positive) side red and . (negative) side black. �� Polar type With surge voltage suppressor (�ｭS) �� DIN or Conduit terminal With light/surge voltage suppressor (�ｭZ) �� DIN or Conduit terminal With light/surge voltage suppressor (�ｭU) �� Non-polar type With surge voltage suppressor (�ｭR) �� Grommet or L/M-type plug connector With light/surge voltage suppressor (�ｭU) �� Grommet or L/M-type plug connector With light/surge voltage suppressor (�ｭZ) . Since the voltage will drop by approx. 0.5 V due to the transistor, pay attention to the allowable voltage fluctuation. (For details, refer to the solenoid specifications of each type of valve.) �� With power saving circuit Power consumption is decreased by approx. 1/3 by reducing the wattage required to hold the valve in an energized state. (Effective energizing time is over 40 ms at 24 VDC.) Refer to the electrical power waveform as shown below. 1861 SYJ VQZ VG VP3 VP A
