Valve Connections and Configuration Wiring Diagram and Connections • 7
If your valve is listed in Table 6-2, select the valve
using the tEP parameter. This way, you can be sure of
the correct configuration.
For connection modes of valves of different
manufacturers, refer to Table 6-4 and Table 6-5.
It
is highly recommended that the maximum distance
of t
he stepper valve harness length between the valve
and the XM678D 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 335-3
500) is only for use
with Sporlan Bipolar 4-wire stepper valves with 100
ohm or 75 ohm phase resistance.
When using the Inductor Exte
nder, the XM678D
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 6-2 for the list of the XM series
controller supported Sporlan Steppe
r 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 335-3
500),
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 e
xtension is not in
conduit, 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 mea
sure
voltage at the
Valve will not produce accurate results with a voltage
chopper constant current stepper valve drivers as used
in XM678D controllers.
Instead, an AC current meter can
be used to measure
valve milliamps as a field verification method.
