3.3 Fault indications via R100 fault log
The table shows the fault log possibilities in prioritized order.
If two faults occurs at the same time, the fault with the highest priority will be shown!
* Depending on the expansion module.

Pump
blocked
Blocked
Stopped •
Motor, rotor, impeller or
pump blocked
•
Fault in terminal box
•
Disassemble pump and
remove blockage.
•
Replace the terminal
box.
The fault must be reset man-
ually before the pump can
run.

Internal
fault
Fault
Stopped The terminal box current
limit has been exceeded
which may be caused by:
•
Fault in the terminal
box
•
Fault in the stator
•
Replace the terminal
box.
•
Replace the stator.
Pump will start automati-
cally when the fault has dis-
appeared and the red indica-
tor light is no longer on.
The pump tries to restart
once every minute.

Overtem-
perature
Fault
Stopped A too high temperature has
been measured in the
pump, which may be caused
by:
•
Too high motor temper-
ature due to stator fault
•
Extremely high liquid
temperature
•
Extremely high ambi-
ent temperature
•
Fault in the terminal
box
•
Replace the stator.
•
Reduce the liquid tem-
perature.
•
Reduce the ambient
temperature.
•
Replace the terminal
box.
Pump will start automati-
cally when the fault has dis-
appeared and the red indica-
tor light is no longer on.

Undervolt-
age
Stopped The supply voltage from
mains is too low.
Check that the supply volt-
age is in accordance with
the data on the nameplate.
Pump will start automati-
cally when the fault has dis-
appeared and the red indica-
tor light is no longer on.

Overvoltage Overvoltage Stopped The supply voltage from
mains is too high.
Check that the supply volt-
age is in accordance with
the data on the nameplate.
Pump will start automati-
cally when the fault has dis-
appeared and the red indica-
tor light is no longer on.

Internal
fault
No fault
indication
Pump is
running.
The terminal box registers
no signal from the HALL sen-
sor in the stator.
•
Replace the stator
•
Replace the terminal
box.
When the fault has disap-
peared, the red indicator
light goes out automatically.
8
75
Internal
fault
No fault
indication
Pump is
running.
Too low DC voltage meas-
ured in the terminal box.
•
Reset the fault indica-
tion.
•
If the fault re-occurs, re-
place the terminal box.
When the fault has disap-
peared, the red indicator
light goes out automatically.
9
83
Internal
fault
No fault
indication
Pump is
running.
Fault in the storing of set
values (pressure) or meas-
ured values (hour counter)
in the internal memory of
the terminal box.
•
Cut off the supply volt-
age, wait for approx. 1
minute, then cut in the
supply voltage again. A
new setpoint has now
been stored, and if no
fault is indicated, the
fault was temporary.
•
If the fault re-occurs, re-
place the terminal box.
Once it has occurred, the
fault will be indicated peri-
odically.
See "Remedy".

Fault in
module
communi-
cation
No fault
indication
Pump is
running.
The terminal box cannot
communicate with the
module fitted (GENI or LON).
(The fault also occurs if the
module is removed while
the pump is operating.)
•
Check that the connec-
tion between module
and terminal box is OK.
See point 3 in section
B1
.
When the fault has disap-
peared, the red indicator
light goes out automatically.
11
*
Fault in
module
No fault
indication
Pump is
running.
The terminal box has
received a feedback from
the expansion module fit-
ted. There is a fault in the
expansion module.
•
Replace the expansion
module.
When the fault has disap-
peared, the red indicator
light goes out automatically.
