Underload Module
Elements
37[1] ,37[2] ,37[3]
Functional Description
When the motor is running, a current reduction might indicate a malfunction in the load. Underload protection
recognizes mechanical problems, such as a blocked flow or loss of back pressure in a pump, or a broken drive belt or
drive shaft.
Refer to the underload protection limit - the left vertical line in the Underload and Jam Trip Function
example. In the
example, the underload trip is set at 60% of FLA. The protective device can be configured for underload alarm and
underload trip. Each can be disabled by entering the >>Underload Setting<< menu and then selecting “Inactive”.
Underload and JAM Trip Function
These would be represented by two such vertical lines, both below the normal load current. Be sure to set the alarm
level
above
the trip level. Both trips and alarms are held off by the start delay. Each has its own run or pickup delay.
