SCF SERIES REMOTE KEYPAD INSTRUCTIONS

(Manual Number: KF01G)

The SCF Series Remote Keypad option (844-200) allows the SCF Series

drive to be programmed and controlled from up to one hundred feet away.

When properly mounted, the remote keypad is rated NEMA 4X.

In addition to the functions available on the front of the SCF drive, the

remote keypad has Start/Stop and Forward/Reverse functions.

Note:

The Remote Keypad option will only work with SCF drives that have

parameter version "309" or "312". It will not work with SCF drives that

have the High Frequency or PI Setpoint Control options. The parameter

version appears momentarily on the drive display when it is powered up,

and also appears on a small label on the drive's heatsink.

WARNING!

If OEM mode is selected (using Parameter 48), and if the OEM Default

setting for Parameter 14 and/or 15 is "01", the remote keypad will

be disabled, and the STOP key WILL NOT work. Refer to the SCF

Installation and Operation Manual for information on OEM Default

settings.
