The actuator can be operated as a 3-position or modulating actuator in two acting
directions depending on the type of connection. It is suitable for both combi valves
VPF.. with 20 mm stroke as well as for valves with a 40 mm and 43 mm stroke. The
stroke is calibrated automatically during initialization.
The actuator includes a position feedback.
The actuator travels to the end position in the event of power loss, see "Fail-safe
function", page 5. Up to 45 seconds pass until the actuator is available again following
a restart or start after the fail-safe function is triggered.
The positioning time (40 to 240 seconds) and the flow characteristic (lin/log) can be set
via the DIL switches.
The manual adjuster is disengaged.
The manual adjuster allows for manually setting the position. The motor is switched off
when the manual adjuster is engaged. The fail-safe function (spring return) is
reactivated after the manual adjuster is disengaged, and the actuator travels again to
the set position without calibration.
The actuator remains in this position without active operating voltage for as long as the
manual adjustor is engaged.
The actuator independently calibrates itself for each type of connection. Initialization
occurs as soon as operating voltage is supplied for the first time and the waiting period
ends. The actuator travels to the lower stop of the combi valve, thus enabling automatic
coupling with the valve stem. It then travels to the upper stop, records and stores it.
Recalibration can be manually triggered any time, see "Recalibration", page 5.
The combi valve can travel to any position by supplying voltage to terminal G1 or G2 as
well as L11) or L21).
∂Voltage on G2, L2: Actuator stem retracts, combi valve opens.
∂Voltage on G1, L1: Actuator stem extends, combi valve closes.
∂No voltage on G1 and G2: Actuator stem stays at the applicable
or L1 and L2: position.

connections G1 and G2 or L1 and L2.
Positioning signal OPEN on G2, L2. Positioning signal CLOSED on G1, L1.
Positioning signal OPEN on G1, L1. Positioning signal CLOSED on G2, L2.
∂Do not use connection Yu (DC 0-10 V) and Yi (DC 4-20 mA).
∂Positioning times can be selected, see "Positioning times“, page 7".
∂Valve characteristic curves "lin" or "log" cannot be selected.
∂Position feedback U is activated after initialization/calibration.
Electronic motor shutdown is triggered in the end positions (valve stop or upon
reaching maximum stroke) or by overload (no end switch).
The combi valve can be driven to any position by connecting a continuous positioning
signal Yu or Yi. The acting direction can be reserved (direct/reverse acting) by
connecting operating voltage to G1 or G2:
Operating voltage AC/DC 24 V on G1 or AC 230 V on L1
∂Pos. signal to Yu, Yi increasing: Actuator stem retracts, combi valve opens.
∂Pos. signal to Yu, Yi decreasing: Actuator stem extends, valve closes.
∂Pos. signal to Yu, Yi continuous: Actuator stem remains in the respective pos.
Operating voltage AC/DC 24 V on G2 or AC 230 V on L2
∂Pos. signal to Yu, Yi increasing: Actuator stem extends, combi valve closes.
∂Pos. signal to Yu, Yi decreasing: Actuator stem retracts, combi valve opens.
∂Pos. signal to Yu, Yi continuous: Actuator stem remains in the respective pos.

∂The input with the higher value has priority when a positioning signal is available
at both Yu and Yi.
∂When using the AC 230 V module ASP1.1, the SQV..P can also be
operated with a DC 0…10 V or DC 4…20 mA positioning signal.
∂The actuator travels to the applicable end position depending on the selected
acting direction if Yu or Yi are interrupted:
Operating voltage to G1 or L1 Actuator stem extends.
Operating voltage to G2 or L2 Actuator stem retracts.
∂Positioning times can be selected, see "Positioning times“, page 7".
∂Valve characteristic curves "lin" or "log" can be selected.
∂Position feedback U is activated after initialization/calibration.
∂Parallel operation with up to 5 actuators possible, see "Technical data", page 10.

Position feedback U (DC 0…10 V) is always proportional to stroke H for the actuator. It
is also active when using the AC 230 V module ASP1.1.

1) Factory setting
The actuator travels to the applicable end position (the stem retracts or extends
depending on the model) using the preloaded spring if operating voltage to terminal G
or L is lost or shut down. In this case, the actuator's control function is locked for 45
seconds (both LEDs are green) to reach the end position at any rate. There is no
recalibration. The reset positioning speed ensures that no pressure surges occur in the
piping.
SQV91P30 Actuator stem retracted Combi valve opened (V = 100%).
SQV91P40 Actuator stem extended Combi valve closed (V = 0%).
Recalibration can be manually triggered any time.
1. Operating voltage is supplied.
2. Engage and disengage the manual adjuster twice within 4 seconds.
3. Both LEDs flash green.
4. Recalibration is successful when both LEDs are lit green.
5. Return to normal control function.
∂Position feedback U is inactive or corresponds to value "0".
∂The shortest possible runtime is initialized.
∂Recalibration is valid only after the entire process is completed.
∂Additional engaging the manual adjuster interrupts the process.
The valve actuator indicates detected blockage by setting the feedback signal to 0 V
after ca. 90 seconds. The actuator, however, tries to overcome the blockage during this
period. Normal control function is reactivated if the blockage is overcome and position
feedback U is once again available.

Blockade detection

6 / 14
Siemens Electromotive actuators for combi valves CE1N4833en
Building Technologies 2017-11-15
Blockade detection is always operational. In other words, the actuator
demonstrates the following response at end positions H100 and H0not only during
initialization and calibration, but also during normal control operation:
1. The actuator travels to the end position; the LED is lit in the direction of travel.
2. It detects the end position; both LEDs are lit green.
3. It then briefly travels in the opposite direction; the LED is lit in the direction of travel.
4. It then returns to the end position; LED is lit in the direction of travel
5. It detects the end position; both LEDs are lit green.
This response is repeated with time intervals between travels increasing
exponentially. The intervals are:
25 seconds
1 min 40 seconds
6 min 40 seconds
26 min
1 h 46 min 40 seconds
7 h 6 min 40 seconds
1 day 4 h 26 min 40 seconds
for the previous interval.
The status and acting direction indication consists of two green, lit LEDs.

Notes
Install electrical connections in accordance with local regulations on electric
installations as well as internal or connecting diagrams as of page 10.
Observe safety regulations and restrictions designed to ensure the safety of people
and property at all times!
∂An internal controller controls the actuator for 3-position or DC 4…20 mA
positioning signal connection types, see "Connection diagrams", page 11.
∂For DC 0…10 V connections (input impedance Ri= 100 kΩ), up to 5 actuators
can be controlled in parallel by a controller with a rating of 1 mA.
∂The switching points must be entered on the plant diagram when using the
double auxiliary switch ASC10.42.
∂Do not insulate the actuator console and valve stem, as air circulation must be
ensured.
∂Non-observance of the above may result in accidents and fires!
∂Do not touch the hot parts without prior protective measures to avoid
burns!
∂For permitted temperatures, see "Technical data", page 10.
