Description Cause Possible solutions
HFPB
High flow
error
High flow error
•
Due to HVAC feedback value is lower
than limit of maximum flow.
•
Check feedback signal is
correct.
•
Check if feedback value is
lower than limit of maximum
flow.
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
