Chapter 5 - Configuring Impulse with an IDC Keypad

Keypad Hardware Features

Adjusting Contrast

On the back of the keypad there is a plastic potentiometer, adjustable with a flathead screwdriver. This is used to adjust the contrast on the LCD display. If the Impulse drive and keypad were purchased together, this adjustment has been made by IDC. Some adjustment may still be necessary to accommodate a variety of lighting conditions or viewing angles.

Remote-Mounting the Keypad

The keypad can easily be mounted and sealed to NEMA 4 specifications by using the included mounting gasket and 6-foot communication cable. See Chapter 6, Hardware Reference, for important information on mounting the keypad and extending cable length.

DIP Switch Settings

DIP-switch settings on the back of the FP100 keypad have no effect on either the keypad or the Impulse drive.

NOTE: If you are using an FP220 keypad with your Impulse, you must set DIP-switch #3 to the ON position and switch #s 1, 2, and 4 to OFF. Setting switch #3 to ON does not apply when using the FP220 with other IDC drives or controls. See appropriate user’s manual or call IDC Applications Engineering for information on keypad applicability.
