10 Faults, causes and elimination

Fault
The pump does not operate Faulty fuse, pump without volt-
with the power supply age
switched on
Cavitation due to insufficient
Pump makes noise
flow pressure
Line overloaded
Line undervoltage
Incorrect infeed by the utility
company
Line overvoltage
E.g. due to deposits
Motor blocking
Deposits in the pump
Motor overload
Motor defective
Short-circuit/ground fault
Module incorrectly inserted.
Connection between motor and
Contact error
module interrupted
Air in the pump
No-load
Limited air inflow to the module
Module overtemperature heatsink.
Control defective, control line
Cable break defective

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.
Cause
Check fuses, rectify voltage interruption.
Increase system admission pressure within the permissible range, check setting for delivery height and
reduce if necessary
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
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
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.
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.
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.
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.
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.
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.
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.
