function. Pressing the LIST key returns the active setting to the display.

There is one occasion when the LIST key is disabled making the corresponding functions inoperative. In a SAMMS-MV device with autoreset disabled at the factory, the LIST key has no effect for F8.

3.28.3 UP and DOWN Keys

Use the UP and DOWN keys to step through the functions while the HHC is in the function mode. When the HHC is in the display mode, use the UP and DOWN keys to step through the values for a selected function. You can use the keys in three ways:

1.Single step - press the key and release it.

2.Slow scroll - press the key and hold the key down for no longer than a two or three seconds.

3.Fast scroll - press the key and hold the key down long enough for the HHC to step through more than five steps.

The following information discusses how to operate the UP and DOWN keys in the function and display modes.

1.In the function mode, the UP key increases the function number by one and the DOWN key decreases the function number by one. If F0 appears on the display, pressing the DOWN key rolls the function over to the highest-numbered function, F27. If the highest-numbered function (F27) ap- pears in the display, pressing the UP key rolls the function over to the lowest-numbered function (F0).

2.In the display mode, use the UP and DOWN keys to step through the range of settings for each set point function. You also use the UP and DOWN keys to step through the individual line currents and the average line current of F15. Just as the UP and DOWN keys cause the function numbers to roll over, they also cause the range of settings to roll over.

3.28.4 Using the ENTER Key

Use the ENTER key to change settings on the HHC display. The SAMMS-MV device disables the ENTER key under the follow- ing conditions:

1.The ENTER key is disabled while the device is in the function mode.

2.The ENTER key is disabled for non-setting functions that display a parameter.

3.The ENTER key is disabled while the motor is running to prevent settings from being changed while the motor is running.

Use the following procedure to change a setting. This example shows you how to change the full-load current setting from 112A to 67A.

1. With the HHC in the program mode (see section 3.29.1),

press the (F)unction key. The display shows the number of the function most recently selected, (e.g. F9).

2.Use the UP or DOWN key (as described above) to step or scroll to the desired function. The display shows the desired function, (e.g. F4).

3.Press the LIST key. The display shows the active setting for the selected function, (e.g. 112, representing a full-load current setting of 112A for a motor controlled by a size H3B contactor.)

4.Use the UP or DOWN key (as described above) to step or scroll to the desired setting. The display shows the desired setting, (e.g. 67 for 67A).

5.To view the active setting, press the LIST key. The number 112 appears on the display.

6.Repeat step 4 to return to the desired setting.

7.To enter the desired setting (67) which is displayed, press the ENTER key. The display becomes blank while you hold down the ENTER key and the SAMMS-MV device stores the new setting.

8.Press the LIST key to show the new setting (67) on the display.

9.To move to the other functions, press the (F)unction key. The display shows, in the example, F4.

10.Press the UP and DOWN keys to step through the function numbers. The SAMMS-MV device is in the function mode.

11.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 display mode.

3.29Using the SAMMS-MV Device Func- tions

This section lists the 28 major motor control and protection functions and several related functions (F0-F27, F6A, F9A, F12A, F23A, and F24A) and how to use them. The functions available for each version of the SAMMS-MV device are shown in table 3.7. Table 3.8 provides a description of each function and its associated range, step size, and default value.

To access a function perform the following steps:

1.Connect the HHC’s cable to the communications port on the front of the SAMMS-MV device.

2.Locate the desired function using the (F)unction and UP and DOWN keys.

3.Then locate and follow the steps provided with the function you wish to perform.
