Description
It is highly recommended that the maximum distance of the stepper valve harness length between the valve and the XEV22D controller must not exceed 30 feet (10 meters). If the valve harness length must be extended beyond 30 feet (10 meters), Emerson Retail Solutions provides an Inductor Extender (P/N 335-3500) for use with Sporlan Valves ONLY. The Inductor Extender (P/N 335-3500) is ONLY for use with Sporlan Bipolar 4-wire stepper valves with 100 ohm or 75 ohm phase resistance.
When using the Inductor Extender, the XEV22D controller “CPP” parameter setting MUST be less than 20; otherwise the Valve, Controller, and/or Inductor Extender will be damaged or have its life expectancy drastically shortened. Refer to Table 4-4 for the list of the XEV series controller supported Sporlan Stepper valves. The Inductor Extender can ONLY be used with Sporlan Bipolar Stepper valves that have a setting of 16 or 12 in the “CPP” column.

The recommended CPP parameter should NOT be increased to create AC voltage at the valve, if the valve harness length is over 30 feet, an Inductor Extender MUST be added into the 4-wire valve harness. When using the Inductor Extender (P/N 335-3500), any stepper valve harness extensions MUST not exceed 170 feet total length. Use 14 AWG wire for valve harness extensions in conduit. If the valve harness extension is not in con- duit, use 16 AWG or 14 AWG shielded cable with the shield terminated to an earth grounded chassis. For valve harness extensions over 100 feet, 14 AWG shielded cable is recommended.
Using an AC volt meter to measure voltage at the Valve will not produce accurate results with a voltage chopper constant current stepper valve drivers as used in XEV22D controllers. Instead, an AC current meter can be used to measure valve milliamps as a field verification method. If the current measurement using the method described below is less than the recommended value by more than 20%, the CPP parameter may be increased by up to 2 (12 to 14 or 16 to 18).
The CPP parameter MUST be less than 20 when using the Inductor Extender (P/N 335-3500). For a CPP parameter of 12, the measured current should be near 120 mA AC, for a CPP setting of 16, the measured current should be near 160 mA AC.
