Manual

● For the detail information and instructions, please refer to the user manual and user manual for communication, and be
sure to follow cautions written in the technical descriptions (catalog, website).
Visit our website (www.autonics.com) to download manuals.

● User manual describes for specications and function, and communication manual describes for RS485 communication
(Modbus RTU protocol) and parameter address map data.

Comprehensive Device Management Program (DAQMaster)

● DAQMaster is comprehensive device management program. It is available for parameter setting, monitoring, and user
parameter group setting, parameter mask setting for only TK4 Series.

● Visit our website (www.autonics.com) to download user manual and comprehensive device management program.

It displays the unit set at display unit

It turns ON during manual controlling.

One of SV1 to 3 indicators will be ON in

case of selecting multi SV function.

It flashes by 1 sec when executing auto

tuning.

alarm output is ON.

8. Control output (OUT 1, OUT 2) indicator:

control output is ON.

※

During cycle/phase controlling in SSRP function model (TK4

- 4S ) when MV is over 5.0%, it turns ON.

※

To use current output, when MV is 0.0% in manual control, it
turns OFF. Otherwise, it always turns ON. When MV is over

3.0% in auto control, it turns ON and when MV is below 2.0%,
it turns OFF.
