2 General Description
The Thyro Power Manager possesses numerous functions. The Unit can also be deployed
for peak load network monitoring next to its use for network optimization (as a substitute for
the previously deployed SYT9 module). The measuring functions register the effective values
of up to three electrical currents (or voltages), and deliver their effective values as DC signals
(as a substitute for three previously deployed ZME modules). In the course of this, the
integration-time feature is capable for adjustment so that measurements can be made during
full frequency operations. Power and energy consumption may also be measured.
Furthermore, the measurement of mains voltage, temperature, and three DC inputs is
performed. These values may also be displayed. A monitoring function is available for the
most of these measurement values. The Unit possesses a serial interface for the purpose of
PC connection, and an interface to the bus modules of the Thyro family. Thus, the capability
is provided for the query of all measurement values via a PC or bus system. Next to the
easily performed adjustment capability via a switch or potentiometer, the Unit can also be
configured via a comfortable PC program (or via a bus). In the operations mode “I/O
Module”, the analog inputs and outputs, as well as the digital outputs, may be set or read via
a bus (or via a PC). Furthermore, an operations time counter is integrated into the Unit.
Basically, the Unit is composed of the following components:
•
Voltage supply 110V /230V
•
Automatic frequency recognition
•
Terminal to a bus module (Profibus)
•
10 Syt-type potential-free terminals
•
RS232-PC terminal
•
Error and alarm output
•
6 analog outputs for 0 -10V
•
3 analog inputs, energy levels are
selectable
•
3 converter inputs for 1V~ / 100%
•
Potentiometers, switches, and LEDs

The Unit is designed for extreme easy operations. Thus, the number of connected power
controllers can directly be adjusted via the rotary switch S2, and the operating mode can
directly be adjusted via the rotary switch S3.
