Grundfos GO Remote. Tripped by the CCP-curve.
The alarm code 51 Blocked appears on the
operating panel. In Grundfos GO Remote, the
alarm Blocked appears.
If the motor has reached the maximum numbers of
restarts, 1 to 3 times, due to a blocked motor, it is
possible to reset the failure up to 3 times manually.
After that LC 231 will wait 24 hours before trying to
restart the motor again. Alternatively, switch off the
main power supply to LC 231 for a minimum of 30
seconds to clear the alarms.
A blockage alarm is typically triggered when the
motor starts and in-rush current trips the motor. The
maximum allowed blockage situations are limited to 6
times during a 24-hour period. If the Maximum
number of blocked motor restart is set to 3, the
control unit tries to restart the motor 3 times before a
manual reset is needed. If it occurs 3 times again
after the reset, the control unit has reached the
maximum number of blockages.
