10 Faults, causes and elimination
11 Spare parts
There are no spare parts available for the Stratos PARA pump.
In the event of damage, the complete pump must be replaced
and the defective unit sent to the system manufacturer.
Fault Cause Description / elimination
The pump does not operate
with the power supply
switched on Faulty fuse, pump without volt-
age Check fuses, rectify voltage interruption.
Pump makes noise
Cavitation due to insufficient
flow pressure Increase system admission pressure within the permissible range, check setting for delivery height and
reduce if necessary
Line undervoltage
Line overloaded In the event of overvoltage or undervoltage, the motor is switched off. It restarts automatically as soon
as the voltage is back within the valid range. Collective fault signal relay active. Off: 165 V AC / On:
195 V AC
Line overvoltage
Incorrect infeed by the utility
company Incorrect infeed by the utility company
In the event of overvoltage or undervoltage, the motor is switched off. It restarts automatically as soon
as the voltage is back within the valid range. Collective fault signal relay active. Off: 265 V AC / On:
245 V AC
Motor blocking
E.g. due to deposits When the motor stalls, a maximum of 5 restarts take place at intervals of 30 seconds each. When the
motor still stalls, it is switched off. The power must be switched off for 30 seconds and then the system
must be restarted. The deblocking program runs at each start. The collective fault signal relay is active
as long as the internal fault counter is not ZERO.
Motor overload
Deposits in the pump When the power consumption of the motor exceeds the limit for more than 60 seconds, an "Overload"
fault is signalled. The motor is stopped and restarted after 30 seconds. If there is no overload within the
next 2 minutes, the internal fault counter is reset. The motor is permanently switched off after 5 unsuc-
cessful restarts. Switch off the power for > 30 seconds to reset. The collective fault signal relay is active
as long as the internal fault counter is not ZERO.
Short-circuit/ground fault
Motor defective The motor is switched off when a short-circuit occurs. It is switched on again after 30 seconds. After 5
short-circuits, the motor is switched off permanently. Switch off the power for > 30 seconds to reset.
The collective fault signal relay is active as long as the internal fault counter is not ZERO.
Contact error
Module incorrectly inserted.
Connection between motor and
module interrupted The motor is switched off if there is no contact between the motor and the module. After 30 seconds,
the motor is restarted. The motor is switched off permanently after it has switched off 5 times. Switch
off the power for > 30 seconds to reset. The collective fault signal relay is active as long as the internal
fault counter is not ZERO.
No-load
Air in the pump The motor is switched off after a certain period under dry running conditions. It restarts after a period
of 30 seconds. If no dry running occurs within the next 2 minutes, the internal fault counter is reset. The
motor is otherwise permanently switched off after 5 unsuccessful restarts. Switch off the power for >
30 seconds to reset. The collective fault signal relay is active as long as the internal fault counter is not
ZERO.
Module overtemperature
Limited air inflow to the module
heatsink. In the event of overtemperature, the motor is switched off. After 30 seconds, the motor is restarted. The
motor is switched off permanently after it has switched off 5 times. Switch off the power for > 30 sec-
onds to reset. The collective fault signal relay is active as long as the internal fault counter is not ZERO.
Cable break
Control defective, control line
defective A cable break is registered with pumps which are regulated via a 0-10 V signal and which are equipped
with software with a cable break function at an input control signal of < 0.5 V. The pump rotates at min-
imum speed.
