    (e.g. thrust, travel). Therefore, operators must ensure that the electric actuator with process controller is only used in operating conditions that meet the specifications used for sizing it at the ordering stage. In case operators intend to use the electric actuator with pro- cess controller in applications or conditions other than those specified, contact SAMSON. SAMSON does not assume any liability for damage resulting from the failure to use the de- vice for its intended purpose or for damage caused by external forces or any other external factors. Î Refer to the technical data for limits and fields of application as well as possible uses. See the 'Design and principle of operation' section.
  • Page 8 − The limit switches switch off the motor in the end positions. − An active blocking protection (A8.3 configuration item = 1, see Annex A) in the electric actuator with process controller prevents the valve from seizing up. − Upon supply voltage failure, the TROVIS 5725-8 Electric Actuator with Process Controller causes the valve to move to a certain fail-safe position. The fail-safe action of SAMSON actuators is specified on the actuator nameplate. Warning against residual hazards The electric actuator with process controller has a direct influence on the valve when it is mounted on the valve.

    Annex A 16.2 Excerpt from Modbus list The firmware version 2.1x of TROVIS 5724-8 and TROVIS 5725-8 Electric Actuators with Process Controller have an integrated RS-485 interface to use the Modbus RTU protocol, which is a master/slave protocol (in which the control station acts as the master and the elec- tric actuator as the slave). The following Modbus functions are supported: Code Modbus function Application Read Coils Read state of several digital outputs in bit format Read Holding Registers Read several parameters Write Single Coil Write a single digital output in bit format Write Single Register...

Any parameters not used in this configured system are written with the default setting. The electric actuator with process controller is delivered with the system code number 10 (fixed set point control, heating with mean value calculation of two sensors and set point de- crease) set by default.
