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.
