Continuous blowdown valves BAE 46, BAE 47 with actuator
Apart from the positions OPEN and CLOSED you can select an OPERATING POSITION for the actuators
EF 0.5 and EF 1. The OPERATING POSITION allows the continuous discharge of a definded amount
of boiler water. The OPERATING POSITION can be adjusted in the actuator via the switching cam. For
more information refer to the attached installation manual “Actuators EF...”. The actuator EF 1-1 has a
feedback potentiometer ( 0 – 000 ohm) but no switching cam for setting an OPERATING POSITION. For
more information on the setting refer to the attached installation manual “Actuators EF...”. The actuator
EF 1-40 sends at regular intervals a data telegram to the controller LRR -40. The data are transferred
via CAN bus in accordance with DIN ISO 898, using the CANopen protocol. For more information refer
to the installation manual of the actuator EF -40.
Wire the actuator EF... in accordance with the attached installation manual “Actuators EF...”.
Factory settings of BAE 46, BAE 47
The default settings of the actuators EF 0.5 and EF 1 are: CLOSED (scale position “0”), OPERATING
POSITION (scale position “”) and OPEN (scale position “4”), Fig. 4, Fig. 5
In the OPERATING POSITION a predefined amount of boiler water is continuously discharged. The
OPERATING POSITION can be set in the actuator via the switching cam. For more information on the
adjustment refer to the installation manual “Actuators EF...”. The default settings of the actuators EF 1-1
and EF 1-40 are: CLOSED (scale position “0”) and OPEN (scale position “4”).
Commissioning
The control lever of the continuous blowdown valve and the coupling of the actuator
become hot during operation. This presents the risk of severe burns to hands and arms
when touching the control lever or the coupling. Do not operate the equipment unless you
are wearing thermally insulated and temperature resistant safety gloves.
Danger
Make sure that the flanged connections of the BA 46, BA 47, BAE 46, BAE 47 are securely tightened and
not leaking. Retighten the stuffing box
C
if there is a leak in this area.

Wiring
During operation moving internals can pinch one‘s hands or fingers. Do not touch moving
parts! The continuous blowdown valves BAE 46, BAE 47 are remote controlled and can
open and close very abruptly.
The terminal strips of the actuator EF ... are live during operation.
This presents the danger of electric shock.
Cut off power supply before fixing or removing the equipment.
