CMT 1000 commissioning and maintenance tool
You can set the parameters of the AVR with the CMT 1000 commissioning and
maintenance tool PC application for Microsoft Windows. CMT 1000 connects to
the AVR through the USB port or Ethernet port. An Ethernet connection permits
access to the AVR from remote locations. For more information on CMT 1000,
refer to the
User Manual
.
Operation
The AVR is controlled by analog and digital I/Os. You can also use control signals
by remote access over MODBUS.
Use CMT 1000 only to set parameters and operation and not as an operator
interface.
For detailed information on operation, refer to the
User Manual
.
Technical data
1) 3-phase power supply and an external 1 mF capacitor required to operate
UNITROL 1020 between 15 A and 20 A nominal excitation current.
2) Machine voltage measurement above 250 V AC requires the connection of the
machine star point to earth (PE).
UL ratings
To use the AVR in a UL compliant way, consider the following:
• Electrical ratings for 55 °C surrounding air temperature
• Maximum surrounding air temperature 55 °C – 70 °C with derating as
follows
• UNITROL 1010 maximum output capability: 5 A/150 V
• UNITROL 1020 maximum output capability: 10 A/150 V
• Use only 60/75 °C rated wires
• For use in a Pollution Degree 2 Environment
Grounding conductor terminal is green-colored or plainly identified with “G”,
“GRD”, “GND”, “GRND”, “Ground”, “Grounding” or IEC Publication 417, Symbol
5019.
Excitation inputs PWR L1, PWR L2 and PWR L3 must be protected by a circuit
breaker rated at 480Y/277 V AC, maximum 15 A when supplied from an AC
source or listed class RK5 fuse rated at 300 V DC, maximum 15 A when supplied
from a DC source.
