P61. Multipump Synchronous
– Speed Limit [P27÷3600]
This parameter (default value depends on the hydraulic) sets the speed limit: the first assist pump
shuts off if the speed goes below this parameter's value.
This parameter only applies to cascade synchronous!
P62. Multipump Synchronous
– Window [0÷100]
By setting the speed window (default value 150), expressed as [RPMx10], this parameter represents
the limit for switching off the next assist pump.
This parameter only applies to cascade synchronous!
P63. Multipump
– Priority
This parameter shows the pump priority value in the Multipump set.
(See par. 7.4.3 for further information)
P64. Multipump
– Revision
This parameter shows the Multipump protocol revision value used.
7.5.7 Test Run Configuration Parameters
Test Run is a particular function which starts the pump after the last stop, in order to prevent the pump
from blocking.
P65. Test Run
– Time Start [0÷100]
This parameter (default value 100), expressed in [hours], sets the time after which, once the pump
stopped for the last time, the Test Run will start.
P66. Test Run
– Speed [Min÷Max]
This parameter (default value 200)sets the pump rotational speed for the Test Run expressed in
[RPMx10]. Min and Max speed are model dependant.
P67. Test Run
– Time Duration[0÷180]
This parameter (default value 10)sets the time duration for the Test Run expressed in [seconds].
7.5.8 Special Parameters
P68. Default Values Reload [
NO
,
RES
]
This parameter, if sets to RES, after confirmation, performs a factory restore operation that loads the
default parameters values.
P69. Avoid Frequently Parameters Saving [NO, YES] [6]
By setting this parameter (
NO
,
YES
) (default value NO) to YES, the user can limit the frequency
with which the drive stores the required value P02 in its EEPROM memory; this could be
particularly useful, not to impact EEPROM retention life, especially in applications with a BMS
controller, which could force a continuous variation of the required value for fine regulation
purposes.
7.6 Fault finding
Referring to par. 7.4.4:
• In case of any alarm that allows the motor to keep on running, the display shows alternatively
alarm code and the value of the current motor rotational speed or of the current (estimated or
measured) pressure, while the STATUS indicator becomes orange
• In case of a failure that stops the motor, the display shows the error code permanently and the
STATUS indicator becomes red.
