These actuators are mounted directly on type VKF46... and VFW41.., VFL41.. butterfly
valves. The butterfly valves have to be closed during installation.
In case of unsteady ambient temperatures connect the built-in heating element to avoid
condensation.
The valve and actuator can be assembled straightforwardly on site. There is no need
for special tools.

Commissioning notes
When commissioning the complete motorized valve consisting of actuator, mounting
set and butterfly valve, always check the wiring and test the functions. This also applies
to any additional components fitted, e.g. auxiliary switch, potentiometer or auxiliary
module (variable positioning time).
VKF41.. or VKF46... butterfly valves can only be commissioned with a SQL36E..
actuator or with an ASK46... manual adjuster fitted.
VFW41.. or VFL41.. butterfly valves can only be commissioned with a SQL36E..
actuator or with an ASK41... manual adjuster fitted.
To avoid pressure shocks on the butterfly, the valves must be driven to its fully open
position (either manually or via positioning signal Y1) prior to activating the pump(s).
The flow rate is adjusted either by driving the electric actuators as required, or by
operating the manual adjuster.
When using a SEZ31.1 auxiliary module set the desired positioning time:
SQL36E65: 30...180 s
SQL36E110: 60…360 s
SQL36E160: 120…720 s
The actuator is designed for a static load in the pipe system. Risks arising from loads
caused by vibrations in the system are not covered: In such cases, the long term
protection of the screw connections on the actuator must be agreed with Siemens.
In the case of the SQL36E..., the manual adjuster is always engaged and cannot be
mechanically disconnected.
