Electric spring return actuator with thermoelectric release
device BAT or BAE72B-S.
•
Release temperature 72°C optional 95°C and 120°C (for
hot-air heating).
•
Operating position (damper "OPEN") and tensioning of the
return spring by applying the supply voltage.
•
24V actuators with connectors that can be removed on site
if required.
•
Safety position (damper "CLOSED") through spring force
when supply voltage is interrupted or the temperature fu-
ses (ambient temperature or internal duct temperature)
respond. Reaction of the thermal fuses interrupts the
supply voltage permanently.
•
Display of the damper end positions is possible by means
of integrated micro switches via potential-free changeover
contacts (S1 – S3 "CLOSED" indicates the closed position;
S4 – S6 "OPEN" indicates the opened position).
•
Manual actuation and fixing in any position is possible in
the de-energised state. It is unlocked manually.
•
On-site function control is possible by means of the control
key of BAT or BAE72B-S.
•
Spare parts: Temperature fuse for temperature inside the
duct 72°C/95°C/120°C (ZBAT72 or ZBAE72 and ZBAT95 or
ZBAE95 and ZBAT120). Exchange takes place by unscre-
wing the two screws of the thermoelectric release device.
Remove the thermoelectric trigger device from the actua-
tor unit. Remove the internal duct temperature fuse from
the thermoelectric release device and replace it with a new
internal duct temperature fuse (ZBAT... or ZBAE...). Screw
the thermoelectric trigger device back onto the actuator
unit. For any other damage, the entire "actuator/thermal
release device" unit must be replaced completely.
Electric spring return actuator with thermoelectric
trigger device BAE72TL.
•
Trigger temperature 72°C optionally 95°C (for hot-air hea-
ting).
•
Supply voltage 24V AC/DC including connector.
•
Connection to LON or Belimo MP bus systems is possible
via communication and power supply units BKN230-24LON
or BKN230-24MP.
Further technical data are available on request.
The safety function is only guaranteed if the
drive has been connected to the supply vol-
tage in accordance with regulations.
Parallel connection of further drives is
possible. Observe performance data.
