Control panel

You can pull out the control panel and tilt it to one of the two available settings.

If you use the optional EC05-PCR extension cable, you can use the control panel while it is detached from the PCR-LE Series.

Detaching the control panel

Hold down the two control panel detachment buttons, and pull the control panel toward you.

The control panel will come free of the PCR-LE Series. The control panel and the PCR-LE Series are connected by a cable. Do not pull hard on the control panel.

Home position

19636.jpg

The screen that is displayed that you turn the POWER switch on is called the “home position” (the basic screen). The home position is the top level in the menu hierarchy. All functions are arranged within the menu hierarchy.

No matter which function you are using, if you repeatedly press ESC, you will move back up through the menu hierarchy towards the home position.

Specifying values

To specify values, use the numeric keypad or the rotary knob. When the cursor is displayed in the entry area, you can use the numeric keypad or the rotary knob to specify a value.

19946.jpg

Numeric keypad operations

If you use the numeric keypad to enter a value, the value that you entered is displayed in the entry area.

To enter a negative value, first press +/- (SHIFT+0).

Press CLR to clear any settings that you have made before pressing ENT.

Press ENT to apply the values that you have specified. If you press ESC before you press ENT, any settings that you have made will be canceled.

19940.jpg

Rotary knob operations

Turn the rotary knob to the right to increase the displayed value. Turn the rotary knob to the left to decrease the displayed value. You do not need to press ENT.

72752.jpg CAUTION

A voltage or frequency that is greater than is necessary may cause damage to the load or put the operator in danger. Be sure to set the voltage and frequency limits. For details, see “Setting Limits”.

Digit function

The digit function enables you to use the rotary knob to change only the specified digit and the higher digits when you are setting the voltage or frequency. This function is useful when you are changing the voltage or frequency in steps.

19911.jpg

1

Check that the PCR-LE Series is in a state in which you can specify a value.

The digit function is valid when the cursor is displayed at a value in the entry area.

2

Press DIGIT (SHIFT+.) until the cursor is displayed at the digit that you want to change.

Only the digit that is indicated by the cursor and the higher digits will be changed (except when the value that you are changing reaches the maximum or minimum settable value).

Each time that you press DIGIT (SHIFT+.), the cursor moves to the left. If the cursor is at the highest digit and you press DIGIT (SHIFT+.), the cursor will move to the lowest digit.
