6.3.5. TEMPERATURE MEASUREMENT

The Thyro-Power Manager possesses a temperature sensor, e.g. the temperature inside the
switch cabinet can be measured and monitored with its help. The temperature value can be
read via a PC program or bus system. Within the standard settings, it is also read out at
analog output 5 (X7.9 / X7.10), whereby 10V = 100°C. Only temperatures > 0°C are read
out. A monitoring limiting value can also be set, if this limiting temperature is over-stepped
(or under-stepped, it is capable for setting), a message occurs at the error output via a PC
program and via a bus system.

6.3.6. MEASUREMENT OF THREE ANALOG INPUTS

The Thyro-Power Manager also measures the mains voltage or supply voltage, respectively.
This measurement can be read via a PC program or bus system. Within the standard
settings, it is also read out at analog output 4 (X7.7 / X7.8), whereby 10V = 230V.
6.3.7. MEASUREMENT OF THREE ANALOG INPUTS
The Thyro Power Manager also measures the values of three analog inputs (see also
chapter 4.5.4.7, page 9 for this). Input ranges can be selected between 0 – 5V, 0 – 10V, 0 –
20mA for two input terminals. The third input terminal possesses a fixed range of 0 – 10V.
Upon demand, the starting default value 0 can be changed to 4mA, 1V, and 2V (an offset
value and live zero). All input terminals can be read via a PC program or bus system.

6.4. I/O MODULE (BUS/PC)

The Thyro-Power Manager can also be used as I/O module for a bus system and from a
PC. In this operational mode, 10 SYT potential-free outputs are used as digital outputs for
network load optimization. They may be set or deleted from a bus or PC. The values of the
analog outputs (AC and DC), as well as the mains voltage and temperature may
(furthermore) be read out via a bus or PC. The values of the six analog outputs may then be
read out from the bus or PC, so that a voltage range of 0 – 10 V may be created for 6 cases
(configure the output to default "bus value").
If the Thyro-Tool Family is installed on a PC, the communication server program is thus also
installed, from which the communication between PC and Thyro Power Manager is
executed. Via the help of this server program, it is also possible to simply implement the
communication from other programs, thus to enable the query and setting of values from the
Thyro-Power Manager (Excel, LabView, Visual Basic, C++ etc.) See also the examples
contained on the Thyro-Tool Family CD.

6.5. MESSAGES

In general, messages are performed via LED, error and alarm output, PC program, or via
the bus system. It can be adjusted via the PC program if a message should be read out via
the error or alarm output.

6.5.1. MESSAGES AT THE ERROR OUTPUT

Within standard default settings, the following messages are read out at the error output:

Mains frequency outside of 47 – 63 Hz

Error temperature monitoring

Invalid parameters

Undervoltage within the network

Overvoltage within the network
The error output can also be configured individually via a PC program or bus system.

6.5.2. MESSAGES AT THE ALARM OUTPUT

Within standard default settings, the following messages are read out at the alarm output:
 Measurement value monitoring of converter 1
 Measurement value monitoring of converter 2

Measurement value monitoring of converter 3
The alarm output can also be configured individually via a PC program or bus system.

6.5.3. FURTHER MESSAGES

An LED is also installed at each of the 10 SYT outputs for the purpose of network load
optimization, from which one can recognize if the output is set or not.
