The connecting socket X10 of the Power Controller is allocated as follows (1:1 connection):
ATTENTION
The LBA receives its power supply (+5V) via pin 8 of the socket X10. It is imperative that this voltage
is not short-circuited. Otherwise, damage to Thyro-P may be incurred.
If a PC is connected to the RS 232 interface, then this pin should be left unconnected, since it is not
needed for data transfer.
Generally, all devices with an RS 232 interface may communicate with Thyro-P. The protocol used
may simply be created by the user himself.
For this purpose, a detailed description of the protocol used may be requested from AEG PS (refer
to application document).
5.2 FIBRE OPTIC INTERFACE
This widely used interface (LL, X30 LLE blue, X31 LLS grey) for quick and secure data transfer is
fi tted to Thyro-P as standard and enables connection of up to 998 Thyro-P Power Controllers. Due
to the good interference immunity, larger distances can be bridged and data can be transferred at
higher speeds.
To install a fi bre optic system, the following interface components can be used.
5.2.1 FIBRE OPTIC DISTRIBUTION SYSTEM
Using the components described below, a complete fi bre optic system for connection of up to 998
Thyro-P may be created.
SIGNAL CONVERTER RS 232 / FIBRE OPTIC
Connection of the fi bre optic to the PC interface (RS 232) is performed using the fi bre optic / RS 232
signal converter shown below. Power supply is via the plug-in power supply enclosed.
