2...
Critical electronics fault
Disconnect the power supply for 1 minute. After
1 minute re-connect the power supply.
Replace the pump set or contact KSBservice.
3...
Internal hardware/firmware fault (incorrect
parameters)
Disconnect the power supply for 1 minute. After
1 minute re-connect the power supply.
Replace the pump set or contact KSBservice.
40
Pump rotor blocked
Remove any contamination from the system.
41
42
Pump set driven by externally forced flow
Check the hydraulic conditions of the system
(system schematic / piping layout). Fit a check
valve if required.
5...
Excessive temperature inside the pump set / Pump
set has been stopped.
Interrupt the power supply and let the pump set
cool down.
Verify the permissible temperature ranges of the
fluid temperature and the ambient temperature.
61
Supply voltage below the permissible limit.
Verify the available supply voltage against the
data on the name plate.
Measure the supply voltage.
62
Supply voltage above the permissible limit.
Verify the available supply voltage against the
data on the name plate.
Measure the supply voltage.
63
Mains voltage phase failure
Check the power supply and fuse elements.
70
Test alert
Disconnect the power supply. Re-establish the
power supply or deactivate the test alert.
8...
Motor fault
Disconnect the power supply for 1 minute. After
1 minute re-connect the power supply.
Replace the pump set or contact KSBservice.
7.3.4 External analog 0 - 10 V DC signal
CAUTION
External voltage applied to the digital inputs
Damage to the printed circuit board!
▷
Always use a volt-free contact for the digital inputs.
Function
An external analog 0 - 10 V DC signal serves as setpoint input. If the Constant-
pressure Control, Proportional-pressure Control or Dynamic Control operating modes
are active, the pump set processes the current external analog signal as a setpoint. If
the Open-loop Control operating mode is active, the pump set processes the external
analog signal as a speed setpoint. If the signal level < 1.5 V DC, the pump will stop
and the last LED segment will extinguish.
