3 Operating the SAMMS-MV Device

1.Press the LIST key to view the sensor in use for overload relay #2. If standard SAMMS sensors are used, the display will read “OFF.” If 5A secondary CT’s are in use, the CT primary current will be displayed.

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

3.Press the UP or DOWN key to scroll through the range of settings, until the selected setting appears on the display.

4.Press the ENTER key to change the active setting to the selected setting. The display becomes blank while you hold down the ENTER key and the SAMMS-MV device stores the new setting.

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 step through to another function.

F6 - Service Factor

1.Press the LIST key to view the active service factor, 1.0 or 1.15. The factory default is 1.15. A service factor of 1.15 adjusts the overload trip thresholds up by 15% over their values for a service factor of 1.0. This results in more margin before tripping.

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

3.To change the setting, press the UP or DOWN key to alternate between the two choices until the selected value is displayed.

4.Press the ENTER key to change the active setting to the selected value. The display becomes blank while you hold down the ENTER key, and the SAMMS-MV device stores the new setting. (If you make an incorrect selection, repeat steps 3 and 4.)

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 step through to another function.

F6A - Motor Type

1.Press the LIST key to view the motor type in use. The factory default is “OdP” for open drip proof. “EFC” designates totally enclosed fan cooled.

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

3.To change the setting, press the UP or DOWN key to alternate between the two choices until the selected value is displayed.

4.Press the ENTER key to change the active setting to the selected value. The display becomes blank while you hold down the ENTER key, and the SAMMS-MV device stores the new setting. (If you make an incorrect selection, repeat steps 3 and 4.)

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 step through to another function.

F7 - Overload Trip Class

The trip class is the time in seconds that it takes the overload relay to trip for a starting current of 600% of the full-load current setting. The range of possible values is 2-23.

1.Press the LIST key to view the active trip class.

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

3.To change the setting, press the UP or DOWN key to scroll through the range of settings until the selected setting appears.

4.Press the ENTER key to change the active setting to the selected value. The display becomes blank while you hold down the ENTER key, and the SAMMS-MV device stores the new setting. (If you make an incorrect selection, repeat steps 3 and 4.)

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 step through to another function.

F7A - Cold Stall Time

1.Press the LIST key to view the active cold stall time in use. (The range of possible values is between 5 and 100 seconds in increments of one second. The factory default value is 10 seconds. If the cold stall time is more than 100 seconds, enter 100.

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

3.To change the setting, press the UP or DOWN key to scroll through the range of settings until the selected setting appears.

4.Press the ENTER key to change the active setting to the selected value. The display becomes blank while you hold down the ENTER key, and the SAMMS-MV device stores the new setting. If the overload class selected exceeds the cold stall time, the word “SUrE” appears on the display requiring reentry before accepting the data.

Important: The word “SUrE” is used as a reminder that supplemental protection is required if the motor acceleration time (overload class) exceeds the allowable stall time for the motor. A speed switch should be used as an input source to open the contactor if the switch senses a locked rotor or stall condition.

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 step through to another function.
