Spindle actuator WMS 306
Installation:
The actuator can be installed in different ways.
The criteria to be taken into account include the
different pressure and pulling forces to be applied or
the varying fitting situations on site.
The actuator can be installed at the actuator end
using a clamping ring and corresponding brackets, or
using an eyebolt.
Ensure that all fastening and clamping screws are
properly tightened.
Settings and adjustments are made on site.
To position the actuator, without power, manually
adjust the spindle rod by turning it to it’s end position,
please be aware the spindle rod can run in a further
5mm when power is eventually applied.
If power is available, power the actuator to its end
stop the position actuator to vent.
The electrical connection is to be made in accordance
with the documentation for central control unit.
Never
access the actuator without the corresponding
motor electronics.
Start-up:
Ensure that the actuator motors are powered in a
voltage range of 19-32V / DC and at a maximum
residual ripple of 20%.
The running direction of the actuators
(OPEN/CLOSED) changes as the motor voltage
polarity changes.
Ensure that a min. 0.5 s delay is allowed between the
OPEN and CLOSED commands
.
Only control the actuators in their self-locking mode.
An activated CLOSED command must be followed by
an OPEN command.
Avoid retriggering of actuators which are run in the
load switch-off mode. This could cause damage to the
actuators.
Ensure that the power supply to the central control
unit on site is such that the start torque of the
actuators can draw up to four times the overall power
for a short period (min. 1 s) without the motor voltage
dropping below 24V/DC.
Note:
Possible danger to persons caused by electric motor
driven sash and frame.
The high forces occurring in the automatic mode
can cause enjury.
Actuators may extend into the room during opening,
for this reason, care needs to be taken prior to
starting up the actuators to exclude the risk of injury.
With vents tilting inwards or outwards, the vent must
be protected from dropping down once the actuator is
unhooked (e.g. for window cleaning).
For safety reasons we recommend the use of
restrictors
In the event that vents or rooflights are subjected to
high rain or wind loads , we recommend connecting
the central control unit to a rain and wind sensor
which will automatically close the vents.
