9.3.2 Pt sensor
Set the warning and trip limits for the Pt sensor.
Factory setting:
• Warning: 50 °C.
• Trip: 60 °C.
Note: Above limits are not active until the Pt sensor
has been activated. See section 9.4.9.
Note: The overvoltage and undervoltage trip limits
will be deactivated automatically if the temperature
monitoring with Pt100/Pt1000 has been set to active.
See section 9.4.9.
9.3.3 Tripping current
Set the rated motor current in the "Max." field.
(See motor nameplate.)
Factory setting:
• Max.: 0.0 A.
Set the min. current limit in the "Min." field. The min.
current limit is typically a dry-running limit. The value
is set in % of max. value.
Factory setting:
• Min.: –40%.
Example:
The rated motor current is 10 A.
The motor is to cut out (trip) at a current below 6 A.
Set "–40%" in the "Min." field.
9.3.4 Current warning
Set the warning limits for "Max." and "Min.".
Set the max. warning limit in the "Max." field.
The value is set in ampere.
Factory setting:
• Max.: 0.0 A.
Set the min. warning limit in the "Min." field.
The value is set in % of max. value.
Factory setting:
• Min.: –40%.
9.3.5 Nominal voltage
Set the nominal supply voltage.
9.3.6 Voltage limits
Set the warning and trip limits for under- and over-
voltage.
Factory setting:
• Warning: ±15%.
• Trip: ±20%.
The values are set in % of nominal voltage.
