Pump 57 : TUL - Low Water Level Alarm Time - OUT
· It sets maintaining time of Low Water Level to issue the low water level alarm.
If the current pressure decreases under the low pressure alarm level (Pump 56) and maintains its state for
a specified time, then display the alarm and stops the operation.

Pump 55 : TUL - Low Water level Alarm Time-LS
· It sets maintain time of low level sensor signal to issue low level alarm.
That is, if the low level sensor signal is continued for more than trip time when low level sensor is selected
from low level trip mode(Pump 54), it is required to display alarm and stop operation as it is detected that
there is no water inside of the inlet pipe.

Pump 54 : TUL - Low Water Level Detection Mode
ㆍ
It is a mode to set up low water level alarm detection method.
ㆍ
In case of setting up low water level sensor, it is required to attach electrode outside on the pipe to detect water
inside.
ㆍ
In case of inter-operation, low water level sensor should be linked to the lowest ID Drive.
※
If there is no water on suction part, all of drives (pumps) will stop.
ㆍ
When it is set to Software detection, it detects the alarm on the basis of low water level alarm and low water level
alarm time. That is, if the operation is continued for more than low water level alarm time (Pump 56) with pressure
under the low water level alarm pressure level (Pump 57), it is required to display alarm and stop operation as it is
detected that there is no water inside of the piping.
