Configuring The Electric Actuator - Samson TROVIS 5757-7 Mounting And Operating Instructions

Mounting and start-up
fixed set point control with room temperature
influence (u KH 5757-7). On using an out-
door sensor, it can change the adjusted heat-
ing characteristic (u KH 5757-7). The
non-floating switching output can alterna-
tively be used as an output for an external
demand for heat.
The connected sensors are monitored for line
breakages. A fault in the line of a sensor is
indicated by the red LED blinking (under-
neath the cover on top of the circuit board).
Each sensor has its own blinking pattern (see
section 3.2). In the event that several sensors
are defective, the LED blinks using the se-
quence for the sensor with the highest priori-
ty:
Highest priority
Lowest priority
Example: In the event that the flow sensor
and outdoor sensor are defective, the LED
initially blinks to indicate that the flow sensor
is defective. When this fault is eliminated, the
LED then blinks to indicate that the outdoor
sensor is defective.
Î Perform the electrical connection depend-
ing on the heating application according
to one of the following wiring diagrams
(Fig. 5 to Fig. 7). As soon as the actuator
is connected to the power supply, the ini-
tialization procedure starts.

The actuator stem extends and the red and
yellow LEDs are illuminated located under
the cover on top of the circuit board.
As soon as the actuator stem has reached
the final position, the red LED is turned off.
The yellow LED remains illuminated and indi-
cates that the actuator is ready for use.
5.4 Configuring the electric ac-
tuator
The actuator is configured with the
TROVIS-VIEW software. All the functions and
parameters are listed in section 10.2.
Information
The Configuration Manual u KH 5757-7
can be found in the Help menu of the
TROVIS-VIEW software. The manual con-
tains a detailed description of each function
and parameter.
