Test Position Feedback (TPF)
If the motor feeder is in the test position, its main circuit is isolated from the network.
However, the control voltage is connected.
The "cold run" function test is performed with the feeder in this state. This means the motor
feeder is tested without a current in the main circuit.
Thermistor protection
SIMOCODE pro V provides the option of connecting thermistor sensors (binary PTC) for
monitoring the motor temperature.
TN-C system
In a TN-C system (FR Terre Neutre Combiné) 1 wire is used simultaneously as a protective
earth (PE) and neutral wire (N).
TN-S system
In a TN-S system (FR Terre Neutre Séparé) the neutral wire and the protective earth are led
separately from the transformer up to the appliance.
Trip class
See "Class".
Unbalance protection
The extent of the phase unbalance can be monitored and transmitted to the control system.
A definable and delayable response can be triggered when an adjustable limit has been
overshot. If the phase unbalance is more than 50 %, the tripping time is also automatically
reduced in accordance with the overload characteristic since the heat generation of the
motors increases in asymmetrical conditions.
Universal Current (UC)
Universal current. Property of devices that can be operated with both AC and DC.
USB PC cable
The USB-PC cable is used to connect the USB interface of the PC to the system interface of
a basic unit for device parameterization.
