WIRING CONNECTIONS
WARNING!
Improper wiring may result in damage to the Remote Keypad. Keep
the remote keypad cable away from power wiring.
The Belden and Carol cables specified consist of two twisted pairs. Make
sure one twisted pair is used for power and the other is used for serial
communications. Do not mix connections between twisted pairs
Note 1:
The supplied cable can be used for distances up to 8 feet in low-
noise environments. For distances up to 100 feet, or in high-noise
environments, use Belden 9842, Carol C4842, or equivalent (24 gauge
minimum) wire only.
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
