Alarm
Description
Auto/On/Off switch
The alarm must be set to enable the Auto/On/Off switch function. If the pump has been started or stopped
by either SCADA/CU 362 operator display or "Auto/On/Off switch" for more than 5 minutes (default), this
alarm is displayed. The user can set the delay as desired and select either warning or alarm. To prevent
personal injury in the event of failure, the pump must be stopped.
Motor protection, tripped
A motor circuit breaker has stopped the pump to protect it.
Common phase error
If one or more phases are missing in a three-phase system, the pumps stop. If the phase sequence is
incorrect, the pump motor rotates in the wrong direction. If this occurs during operation, the pump either
stops or does not start.
Contactor
An "NO" auxiliary contact is used for feedback from the main contactor to check that the contact set is not
welded or hanging.
Low flow
The low-flow limit can be set to receive an indication that a decrease in pump performance has occurred.
Overtemp., PTC/Klixon (IO 351B)
This fault stops the pump, but the pump automatically restarts once the fault is corrected and the pump
has cooled.
Water-in-oil sensor
Faulty water-in-oil sensor.
Overload
The pump consumes more current that expected. The pump may be blocked.
Underload
The pump consumes less current that expected. The pump may run dry.
Latest runtime
The maximum time the pump is allowed to operate without interruptions. At the end of the alarm time set,
the pump stops and the other pump starts, provided that the conditions of pump operation are still fulfilled.
This setting is intended for a system with pump alternation, characterised by an almost identical inflow
and pump capacity. This results in forced alternation when a pump reaches its maximum operating time.
Max. starts/hour
The desired maximum number of starts per hour can be set. The warning is displayed if the number of
pump starts per hour exceeds the limit set.
Time for service
The warning is displayed if the recommended service interval has been exceeded or if the total pump
operating time exceeds the limit set.
GENIbus com. fault (IO 111)
GENIbus communication fault with IO 111.
IO 11x warning
IO 11x indicates a warning (all warnings from the module).
IO 11x alarm
IO 11x indicates an alarm (all alarms from the module).
Torque
The torque is too high (CUE only).
VFD not ready
Feedback signal missing (VFD only).
CUE warning
CUE indicates a warning (all warnings from the module).
CUE alarm
CUE indicates an alarm (all alarms from the module).
MP 204 warning
MP 204 indicates a warning (all warnings from the module).
MP 204 alarm
MP 204 indicates an alarm (all alarms from the module).
Ammeter
Faulty ammeter.
Power meter
The power meter is out of range, for example lower or higher than 4-20 mA.
Blocked
The alarm is displayed if the set limits for "Anti-blocking" are exceeded.
See the section about anti-blocking.
Moisture
The moisture sensor indicates an alarm.
