LED display Description Cause Possible solutions
L0PB
Low pressure
error
Low pressure error
 The feedback signal is not
connected.
 Due to feedback value of
pump pressure is lower
than limit of minimum flow.
 Check feedback signal is
correct and with
connection.
 Check if feedback value
of pressure is lower than
limit of minimum
pressure.
HIPB
High pressure
error
High pressure error
 Due to feedback value of
pump pressure is lower
than limit of maximum flow.
 Check feedback signal is
correct.
 Check if feedback value
of pressure is lower than
limit of maximum
pressure.
LSCFT
Low suction
error
Inadequate suction error
 Insufficient water of supply
tank leads to insufficient
suction.
 PID difference is higher
than its level or current is
lower than output current
level.
 Check if water of supply
tank is enough, and water
supply is regular.
 Check PID difference is
higher than its level or
current is lower than
output current level
FIRE
Fire override
mode
Fire override mode
 Fire override mode is
active
 None
 (Fire override mode is not
a kind of warning).
SE10
PUMP/HVAC
Setting error
PUMP/HVAC settings of
inverter error
 PUMP selection of inverter
(23-02)> (23-03).
 HVAC selection of inverter
(23-46)< (23-47).
 Check pump selection of
inverter (23-02) and
(23-03) settings.
 Check HVAC selection of
inverter (23-46) and
(23-47) settings.
COPUP
PUMP
communication
breaking error
Breaking error of multiple
pumps communication
 Communication breaking
or disconnection of pump
cascade control.
 Check if it has setting
issue or is not properly
connected.
Parameter
Setting Error
Parameter setting error
 Error of Parameter setting
occurs.
 Refer to the instruction
manual or this parameter
is selected to be disabled.
Warning of
Direct Start
When 07-04 is set to 1, the
inverter can not start directly
but displays the warning
signal.
 Set the digital input
terminal (S1~S6) to run
and simultaneously set
07-04=1.
 Check the digital input
terminal and disconnect
it. Then reconnect the DI
terminal after the setting
delay time (07-05) ends.
