F22 - Process Current Warning Level (SAMMS-MVX Only)

1.Press the LIST key to view the active process current level. The value represents the percentage of the full load current setting above which a motor current causes the External Trip LED to flash. The function is disabled for five times the class time after starting, or after a speed or direction change. The range of settings is in 1% increments from zero (OFF) through 100. The factory default is OFF.

2.To change the setting, you must be in program mode.

3.To change the setting, press the UP or DOWN key until the desired setting is displayed then press the ENTER key to select the setting. The display blanks while the ENTER key is pressed.

5.To exit the program mode, press and hold the (F)unction key for several seconds. The display will show “Prog.” Press the UP or DOWN key to change to the display mode.

6.Press the (F)unction key to go to other functions.

F23 Jam Protection (SAMMS-MVX Only)

1.Press the LIST key to view the active jam protection setting (ON or OFF). The factory default setting is ON. If jam protection is enabled (ON) and the motor running current increases to the pickup current value within 360 msec, the motor will trip off-line and the External Trip LED is steadily lit. The function is disabled for five times the class time after starting, or after a speed or direction change.

2.To change the setting, you must be in program mode.

3.To change the protection setting, press the UP or DOWN key to display ON or OFF, then press ENTER to select the setting that is shown. The display blanks while the ENTER key is pressed.

1.Press the LIST key to view the jam current pickup value in use. The range of possible values is between 120% and 400% to the FLC, in increments of 5%. The factory default is 200%.

2.To change the setting, you must be in program mode.

3.To change the setting, press the UP or DOWN key until the desired setting is displayed then press the ENTER key to select the setting. The display blanks while the ENTER key is pressed.

1.Press the LIST key to view the active loss of load setting (ON or OFF). The factory default setting is warning (OFF), and the other setting is protection (ON). This function is disabled for five times the class time after starting or speed or direction changes.

a.When protection (ON) is selected and the motor current drops below the pickup current value, within 360 msec, the External Trip LED will light and the SAMMS-MV trips.

b.When warning (OFF) is selected and the motor current drops below the pickup current value within 360 msec, the External Trip LED flashes but the SAMMS-MV does not trip.

2.To change the setting, you must be in program mode.

3.To change the protection setting, press the UP or DOWN key to display ON or OFF options, then press ENTER to select the setting that is shown. The display blanks while the ENTER key is pressed.

6.Press the (F)unction key to step through to another function.

F24A - Loss of Load Pickup Current (SAMMS-MVX Only)

1.Press the LIST key to view the active setting. The range of possible values is between 20% and 95% to the FLC, in increments of 5%. The factory default is 50%.

2.To change the setting, you must be in program mode.
