3. Technical specication
3.1 Functions and application areas (Intended use)
ARIS actuators are exclusively designed for industrial use. ARIS actuators are utilized for operating regulating and shut-off appli-
ances (valves, ball valves, taps, slide valves, dosing pumps, etc.).
ARIS actuators may not be used for:
• Temperatures below or above the specied data
• Underground environments
• Near open res
• Under water
3.2 Safe and accurate use
ARIS actuators are factory checked prior to delivery. The nal functional testing must be performed within the total system by
qualied technical personnel.
The ARIS company assumes no liability for any direct or indirect damage arising from
• an insufcient test period of the actuator in the total system,
• an improper utilization of the actuator,
• a further utilization after an error was detected.
Perform controls on a regular basis during the operation. Pay particular attention to:
• intended utilization of the actuator (Chapter 3.1);
• unusual sounds, severe vibrations or increased temperatures;
• examine the correct tightening torque and impermeability of xing screws, cable entries, cable glands and sealing plugs;
• the condition of the electrical lines.
Should malfunctions arise, you have to stop the actuator and remedy the malfunction.
All persons who do the installation, commissioning and setting must
• be specially trained and qualied;
• be mentally and physically capable;
• observe the operating instructions.
• Valves, levers and connecting rods are moving during actuator operation.
• Check for proper function of all emergency equipment on your machinery/system.
