For special cable lengths of the AC / DC 24 V actuators.
· Type ASY99 for 3-position actuators SSA81../00
· Type ASY100 for DC 0…10 V modulating actuators SSA61/00
The terminal block connectors are supplied complete with mounting
instructions (74 319 0385 0).
Notes
The actuators must be electrically connected in accordance with local regulations (refer
to "Connection diagrams", page 9).
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 7) 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.
Actuator types SSA 31.1 and SSA81.1 have a built-in auxiliary switch. The switch
cannot be fitted in other actuators later.
Mounting instructions (Ref. 74 319 0497 0) are enclosed in the product packaging.
The actuator and valve are assembled with the coupling nut; no tools or adjustments
are required.
The actuator must be fitted in position 1 with the power disconnected (refer also to
"Manual override", page 6):
· Position the actuator and tighten the coupling nut manually
· Do not use any tools such as wrenches
· Avoid lateral pressure or (cable) tension on the mounted actuator!
In the case of actuators without a connecting cable (SSA../00), the separately ordered
terminal block connector and connecting cable must be fitted.

Crimp ferrule on stripped wire of connecting cable.
When commissioning, check the wiring and the functioning of the actuator and auxiliary
switch, if fitted.
· Actuator stem extends (from position 1 to 0): Valve closes
· Actuator stem retracts (from position 0 to 1): Valve opens
During commissioning and whenever
the operating voltage is switched on,
the SSA61.. runs a self-calibration
routine. (Valve stroke 0 ® Max.
stroke ® Setpoint).
Never intervene manually in this
process.
