P03.01
- If set to OFF, password management is deactivated; access to settings and the control menu is free.
P03.02
- With P03.01 active, value to be specified to activate user level access. See the
Password protected access
chapter.
P03.03
- As P03.02, referred to Advanced level access.
P03.04
- If set to a numeric value, it becomes the code to be specified via serial communication line before being able to send remote controls.

P04.01 –
General enabling of thermal protections set with parameters P04.02 and P04.03. If this parameter is set to OFF (for example, for starting multiple motors with a single
starter) both protections will be disabled.
P04.02 – P04.03
- Define the motor electronic thermal protection class, for the starting and run phases respectively. The thermal protection class is set in relation to the type of
use of the motor. Class 10 is adapted to normal use, classes 15, 20 etc. for heavier duty use. If the motor has a heavy duty application, for more effective protection you
can set the starting protection class higher than the run protection class.
P04.04 –
Determines the value of the thermal status beneath which the motor thermal protection alarm is reset.
P04.05 –
Defines whether terminal IN3 is used as a digital input or as PTC sensor input.
P04.06 –
This function is used in unsupervised applications with 2-wire motor starting command. If the motor is stopped by an alarm with ‘Automatic reset’ enabled, after a time
defined in P04.07 the alarm resets and hence the motor starts again. If after the reset the motor does not restart, a number of motor reset and restarting attempts are
made as set. During the alarm status, the display alternates the active alarm and the time remaining to the automatic reset.
P04.07 –
Delay between successive automatic reset attempts.
P04.08 –
Normally used as protection against pumps dry running or to detect failure of transmission chains or belts. When the torque is lower than this setting, after the delay set
in P04.09 the alarm
A09 Load too low
is generated. The trip delay is reset if the torque returns to a value of 10% higher than the setting.
P04.09 –
Load too low alarm trip delay.
P04.10 –
Checks that the motor starting process does not exceed the set time, i.e. that the mechanical assemblies have not been modified (due to wear or failure) in such a way
that prevents the machine from starting properly. A starting time longer than this setting trips alarm
A10 Starting time too long
.
P04.11 –
Enables control of the power phase sequence, i.e. the direction of rotation of the motor. Setting L1-L2-L3 corresponds to forwards rotation, L3-L2-L1 to reverse. A
sequence other than that specified trips alarm
A03 Incorrect phase sequence
.
P04.12 – P04.13 –
A voltage lower than P04.12 for longer than the time P04.13 trips alarm
A19 Line voltage too low
.
P04.14 – P04.15 –
A voltage higher than P04.14 for longer than the time P04.15 trips alarm
A20 Line voltage too
high.
P04.16 – P04.17 –
Controls the current asymmetry during full voltage running. Asymmetry greater than the setting for a time longer than P04.17 trips alarm
A06 Current
asymmetry
.
P04.18 –
Generates alarm
A22 Maintenance request
when the motor exceeds the set number of hours of operation. This is reset with the command
C01 Reset maintenance
counter
which simultaneously restores the hour meter.
P04.19 –
Defines the origin of the alarms reset command.
STOP
= The alarms are reset when the STOP input opens.
START
= The alarms are reset when the START input
closes.
STA-STO
= Both of the above.
