Standard solenoid valves with a surge killer (option ode "N") are very effetive to eliminate sparks. However, adequate onsideration should e given to the servie life of the relay to avoid ontat welding due to inrush urrent at solenoid exitation. In appliations where ontat welding due to inrush urrent is expeted, solenoid valves with a surge killer (with resistane) (option ode "NR") are effetive. Note, however, they are not as effetive as standard solenoid valves with a surge killer (option ode "N") in terms of elimination of sparks. When using solenoid valves without a surge killer, adequate onsideration should e given to protetion against the reverse surge voltage generated at demagnetization of the solenoid. (It is advisale to inorporate a surge asoring element suh as a varistor in the iruit.) Be areful aout the polarity (+/ ) when wiring the terminal ox (6) for the M12-4-pin onnetor type. Carrying urrent with miswiring will ause short-iruit urrent to flow into the uilt-in diode and damage the diode and drive iruit. -7

If the tank line piping is onneted to a ommon line rather than an isolated line 1 eing provided, the spool may rotate in the reverse diretion unexpetedly due to surge pressures generated y swithing of other diretional ontrol valves. When 5 onneting the tank line to a ommon line, inorporate a hek valve in the tank line or arefully onsider the piping length of the tank line y using the example test given elow as a guide.
