F3 - Size for Overload Relay #2 (SAMMS-MVX Only)

Overload relay #2 protects two-speed motors running on low speed. The possible values are H3A, H3B, H3C, H6 and OFF. OFF appears for single-speed motors. Use the following proce- dure to display the size for overload relay #2.

1.Press the LIST key to view the size selected for overload relay #2.

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.

F4 - Full-Load Current for Overload Relay #1

1.Press the LIST key to view the active full-load current setting for overload relay #1. The setting should normally be the full load current as shown on the motor nameplate (high speed for two-speed machine). The range of possible settings and the factory default value depend on the size displayed in F2 as follows:

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

F4A - 5A CT Primary Current Selection for Overload Relay #1

SAMMS-MV is normally used with SAMMS sensors to provide the current input signals to the device. Optionally, SAMMS-MV may be used with conventional 5A secondary current trans- formers.

1.Press the LIST key to view the sensor in use for overload relay #1. 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.

F5 - Full-Load Current for Overload Relay #2 (SAMMS-MVX Only)

1.Press the LIST key to view the active full-load current setting for overload relay #2. This setting should normally be the full load current for the low speed shown on the motor name- plate. The range of possible settings and the factory default value depend on the size displayed in F3. The values are similar to those found in the table in the procedure for F4. If the control is not a two-speed control, OFF appears on the display, and UP, DOWN and ENTER keys become disabled.

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.

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.

F5A - 5A CT Primary Current Selection for Overload Relay #2 (SAMMS-MVX Only)

SAMMS-MV is normally used with SAMMS sensors to provide the current input signals to the device. Optionally, SAMMS-MV may be used with conventional 5A secondary current trans- formers.
