User configuration menu
To open this menu, press simultaneously the left arrow key, the right arrow
key, and ON/OFF button of the pump control card.
If the security password is enabled, the security password must be entered
to access this menu. By default, all the equipments is set to 000 that the user
may change at any time. If the security password is not enabled, direct access
will be given to the following menu:
1. MAXIMUM RPM ALARM: this will be a value set between 0 and the value
programmed in the MAXIMUM RPM field. If we do not wish this alarm to be
operational it must be programmed to the MAXIMUM RPM value. The default
value is 100 (consequently, alarm not operational).
2. MAXIMUM RPM ALARM TIME: this will be a period programmed between
0 and 999 (in seconds). In the event that the output RPM exceed the value
programmed for MAXIMUM RPM ALARM during the period established in this
field, MAXIMUM RPM error will be activated (the pump will stop, and an error
message will be displayed). By default, this value is 30 seconds.
3. MINIMUM RPM ALARM: this will be a value set between 0 and the value
programmed in the MAXIMUM RPM field. This value may never be greater
than the value programmed in the MAXIMUM RPM ALARM field. If the value
programmed is ‘0’ the error function will be disabled. By default, this value is 0
(disabled).
4. MINIMUM RPM ALARM TIME : this will be a period programmed between
0 and 999 (in seconds). In the event that the output RPM are less than the
programmed value for MINIMUM RPM ALARM during the period established
in this field, MINIMUM RPM error will be activated (the pump will stop, and an
error message will be displayed). By default, this value is 30 seconds.
5. PUMPING SAFETY FUNCTION: this consists of an editable field (0 enabled –
1 disabled). By default, this is set to ‘0’ (enabled).
6. SECURITY PASSWORD: The security password may be changed in an editable
field. The current password must be entered to access and edit the field. (See
the section ‘Password security’ in this chapter).
7. ENABLING THE SECURITY PASSWORD: this consists of an editable field (0
