6.4. Valve Connections and Configuration
6.4.1. Types of Cables and Max
Length
To connect the valve to the controller, use only the
shielded cables with section greater than or equal to
2
0.823 mm
(AWG18). A twisted shielded cable with
the above specification is suggested. Don't connect
the shield to the ground, keep it floating. The
maximum distance between an XM controller and a
valve must not exceed 10 meters.
NOTE: In any case, the unique and valid reference has to be considered the data sheet made by valve
manufacturer. Emerson Retail Solutions cannot be considered responsible in case of valve damage due to
incorrect settings.
CAUTION:
1. Configure the driver by making the correct changes on the parameters before connecting the valve. Select
the kind of motor (tEU parameter) and check if the valve is present in the tEP parameter table (Table 6-2).
2. The maximum distance between an XM controller and a valve must not exceed 10 meters. Use only shielded
cables with section greater than or equal to 0.325 mm² (AWG22). A twisted shielded cable with the above specification
is suggested. Don't connect the shield to any ground, leave it floating.
For valve settings, refer to the manufacturer's data sheet. The manufacturer will not be responsible for any case
of valve damage due to incorrect valve settings.
*Note that Sporlan has issued new valve setting recommendations for the following valves. Refer to Sporlan
Bulletin F100-10-4 June 5, 2017 for more information. Sporlan recommends manually entering these settings
(Table 6-3 below) if you have these valve models. Refer to the XM Release Notes P/N 026-4256 for more
