3.5 Supply 2-wire-system
The supply created by the electronics of the ASM 400 is approx. 6 V
consideration when planning your power supply. The limits for the power supply can be calcu-
lated as follows:

On the device, two brown cords have been installed. These are connected galvanically, so that you can freely
choose the cord for installation.
This cord must be connected with supply + of the power supply unit.
This cord must be connected with supply + of the transmitter.
This cord of contact 1 must be connected with the respective load
resistor R

This cord of contact 2 must be connected with the respective load
resistor R

This cord must be connected with supply + of the power supply
unit.

This cord must be connected with supply - of the power supply
unit.
This cord of contact 1 must be connected with the respective load
resistor R

This cord of contact 2 must be connected with the respective load
resistor R

This line must be connected with the positive power supply (only
for 3-wire-circuit 0 ... 10 V).

This cord must be connected with signal + of the transmitter.
Normally, it is the same as supply - of the transmitter
(only for 3-wire-circuit 0 ... 10 V).
