S1.1 When using the external analogue input X11 AI 3/4, the switch S1.1 must be
in position On.
S1.2 Switch for setting the position feedback via position transmitter potentiom-
eters/ RWG (option).
S1.2 = OFF: The actuator is equipped with a potentiometer.
S1.2 = ON: Switch may only be in this position if an RWG (0/4 – 20 mA) is
installed in the actuator.
When starting the system, the LEDs 0 to 7 will be illuminated. LEDs L1 to L4
are switched off. This signifies that the board is correctly started.
After a short time (approx. 1/4 s), the LED L1 (round red LED) will be illumi-
nated and the LEDs 0 to LED 7 will be switched off one after the other. This
means that the microcontroller is now operating. If LED L1 is switched off
and the LEDs 0 to 7 are still illuminated, then the system is in the reset
status (this situation can also be reproduced by constantly pressing push
button T1).
Indications of operation
LED
0 (red) torque seating
1 (red) no parity
2 (red) 2 stop bits
3 (red) data exchange
4 (red)
5 (red) bus active
6 (red) local error
7 (red)
LED 0 Indicates torque or limit switching in end position CLOSED
(illuminated for torque switching)
LED 1 Indicates the quantity of the parity bits from the Modbus protocol
(illuminated for No Parity). Only No Parity and Even Parity are
supported, Odd paritiy is not supported
