Data Sheet for Product
Notes
The actuators must be electrically connected in accordance with local regulations (refer
to «Connection diagrams»), page 8.
Regulations and requirements to ensure the safety of people and property must
be observed at all times!
The permissible temperatures (refer to «Technical data», page 6) must be observed.
The connecting cable of the actuator may come into contact with the hot valve body,
provided the temperature of the valve body does not exceed 80 °C.
SSB 31.1.. and SSB81.1.. actuators have an auxiliary switch ready integrated.
Subsequent fitting to other types of actuators is not possible.
The Mounting Instructions 4 319 0497 0 are enclosed in the product packaging.
Assembly is made with the union nut; no tools or adjustments are required. The
actuator must be fitted in position 0 (also refer to «Manual override», page 5) without
operating voltage.
In the case of actuators without connecting cable (SSB../00), the separately ordered
terminal block connector and connecting cable must be fitted.

Crimp ferrule on stripped wire of connecting cable.
When commissioning, check wiring and the functioning of the actuator and auxiliary
switch, if fitted.
• Actuator stem extends (from position 0 to 1): Valve opens
• Actuator stem retracts (from position 1 to 0): Valve closes
During commissioning and
whenever the operating voltage is
switched on, the SSB61.. runs a
self-calibration routine. (Valve

The second or third attempt at calibration occurs automatically after an 8-minute
delay.
After three failed calibration attempts the actuator stem remains in the extended
position and the V..P45.. valves are opened.
For valves with strokes < 1.5 mm, the actuator/valve combination locks after
three failed calibration attempts.
