Table 4: Load Parameter Descriptions
Text describing the type of machine. (RTX only)
Number identifying the machine. (RTX only)
Defines the full load current the Protection Element expects to
see. This determines the scaling of current readings, the base
current for motor overload or inverse time over current protection
and the trip levels for short circuit protection.
Defines the short circuit trip level as a multiple of the full load
current setting.
Determines how long the current reading needs to be above the
trip level before the Protection Element trips.
Selects if the over current protection will use one of the inverse
current-time curves or thermal motor protection curve. This
selection also impacts the short circuit functionality.
Over Current Time Multiplier
(TMS)
Determines the trip time characteristic for Over Current/Motor
Overload.
Over Load Cooling Multiplier
Defines the cooling output of the thermal model, when thermal
motor protection is selected.
Over Load Start Block Level
The thermal accumulator must be below this value to allow an
outlet start.
Current Balance Trip Level
Selects the trip level for or disables current balance protection
Selects the trip level for or disables under current protection
Earth Leakage Trip Level*
Selects the trip level for earth leakage protection
Selects the maximum trip time for earth leakage protection
Residual Voltage Trip Level**
Selects the trip level for residual voltage protection
Residual Voltage Trip Time**
Selects the maximum trip time for residual voltage protection
Earth Continuity Trip Level
Selects the nominal series earth continuity trip level
Earth Continuity Trip Time***
Selects the maximum trip time for both series and shunt earth
continuity protection
Pilot Interlock Trip Time****
Selects the maximum trip time for shunt and open circuit earth
continuity protection
Selects whether earth continuity trips are latch (requiring general
reset) or automatically reset when healthy
Enables remote start of the outlet via the pilot signal. When the
pilot is set to diode mode, the remote start function uses a 100Ω
series start resistor. When remote start is enabled, the PLC will
not be able to initiate a start.
Insulation Test Trip Level
Selects the trip level for or disables the automatic insulation test.
