PRODUCT DESCRIPTION
e SPV-8-010-CP potentiometer is intended for stepless control of EC motors
requiring a 0—10 VDC, 0—20 mA or 0—100 % PWM control signal. e minimum
output values can be adjusted via Modbus within the ranges: 0—4 VDC / 0—8 mA
/ 0—40 % PWM and the maximum output values – within 6—10 VDC/ 12—20 mA
/ 60—100 % PWM. In OFF position, the output is 0 VDC. It features dry contact for
remote on / off switching of external equipment.

For the complete Modbus register data, refer to the product Modbus Register
Map, which is a separate document attached to the article code on the website
and contains the registers list. Products with earlier firmware versions may not be
compatible with this list.
NOTE
Optional settings
To assure correct communication, the NBT needs to be activated in only two devices
on the Modbus RTU network. If necessary, enable the NBT resistor via 3SModbus or
Sensistant (Holding register 9).

OPERATING INSTRUCTIONS
ATTENTION Use only tools and equipment with non-conducting handles when working on
electrical devices.
e unit is intended for use with EC fans / motors. It restarts after power failure.
In case of faulty operation, please check if:
■the right voltage is applied
■all connections are correct
■Modbus communication is working and all settings are accessible via Modbus RTU
TRANSPORT AND STORAGE
Avoid shocks and extreme conditions; stock in original packing.
WARRANTY AND RESTRICTIONS
Two years from the delivery date against defects in manufacturing. Any modifications
or alterations to the product after the date of publication relieve the manufacturer
of any responsibilities. e manufacturer bears no responsibility for any misprints or
