NOTE: Verify dimensions on printed page before using as a template.
Hold this page against the panel where the remote keypad is to be
mounted, and use a center punch to mark the location of the three holes.

4. 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 connections to 13B and 13E and
the other is used for connections to 11 and 2. Do not mix connections
between twisted pairs
Note:
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.
SCL/SCM SERIES REMOTE KEYPAD INSTRUCTIONS
(Manual Number: KM01C)
The SCL/SCM Series Remote Keypad option (844-240) allows the SCL/
SCM Series drive to be programmed and controlled from up to 8 feet away
(typically from the front of the enclosure that houses the SCL/SCM drive).
When properly mounted, the remote keypad is rated up to NEMA 4X.
In addition to the functions available on the front of the SCL/SCM drive,
the remote keypad has Start/Stop and Forward/Reverse functions.
Note:
The Remote Keypad option will only work with SCL/SCM drives that
have parameter version “320” or higher. 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
settings for Parameters 11, 12, and 14 are not “13”, “21” and “02”
respectively, the remote keypad will be disabled and the STOP key
WILL NOT work. Refer to the SCL/SCM Installation and Operation
Manual for more information on OEM Default settings.

Reverse/Forward key: Selects Forward or Reverse direction.
The R/F key is only active if Parameter 17 - ROTATION is
set to “02” (FORWARD AND REVERSE).
When the R/F key is pressed, the symbol for the opposite
direction will blink on the display. Press the Mkey within
four seconds to confirm the rotation change.
Below are the display symbols used to indicate direction:
FORWARD REVERSE
6. REMOTE KEYPAD FUNCTIONS
The Mkey and the pand qkeys on the remote keypad function the
same as the Mode button and the pand qbuttons on the drive. The
other remote keypad functions are described below:
STOP key: Press STOP to Stop the drive. The STOP key
is active whenever the remote keypad is operational.
RUN key: Press RUN to Start the drive. TB-1 must be closed
to TB-11. See the wiring diagram in Section 4.
5. SETTING UP THE SCL/SCM DRIVE
To set up the SCL/SCM drive to work with the Remote Keypad, the
following parameters must be programmed:
P11 TB-13B FUNCTION Set to REMOTE KEYPAD (13)
P12 TB-13E FUNCTION Set to REMOTE KEYPAD (21)
P14 CONTROL Set to REMOTE KEYPAD ONLY (02).
When this is done, and the Remote Keypad is connected, only the Remote
Keypad can start the drive and select direction. This results in some
functions of the drive being unavailable. These are explained below:
1. The Dynamic Braking option cannot be used because TB-13E is
required for the Remote Keypad.
2. Settings 05, 06, and 07 on TB-13A (Parameter 10) are disabled.
These settings are related to direction control. Only the Remote
Keypad can be used for direction commands.
Refer to the SCL/SCM Installation and Operation Manual for more
information.
Note:
Once the drive is set up for Remote Keypad control, the buttons on
the front of the drive are disabled. If they are pressed, the drive display
and Remote Keypad display will show “SE”, indicating that the buttons
are disabled.
8. TROUBLESHOOTING
CONDITION / DISPLAY POSSIBLE CAUSES
Remote Keypad display
is blank, or only the
decimal points are
illuminated.
Parameter 14 - CONTROL is set to “01”
(TERMINAL STRIP ONLY).
Parameter 11 - TB-13B is not set to “13”.
Parameter 12 - TB-13E is not set to “21”.
The Remote Keypad is not wired correctly
to the drive.
Remote Keypad and/or
SCL/SCM drive displays
“JF”.
“JF” typically indicates a communication
problem. Check for proper wiring between
the remote keypad and the drive.
A “JF” fault can also occur if an attempt
is made to start the drive and TB-1 is not
closed to TB-11.
The R/F key does not
work to change rotation
direction.
To use the R/F key to change rotation
direction, Parameter 17 - ROTATION
must be set to “02” (FORWARD AND
REVERSE).
Once the desired rotation direction is
selected, the Mkey must be pressed within
4 seconds to confirm the change.
R F
RUN
STOP
WARNING!
If the remote keypad display is totally blank or only the decimal points
are lit, or is displaying a “JF” fault, the STOP key WILL NOT stop the
drive. The remote keypad must be operational in order for the STOP
key to be active
7. REMOTE KEYPAD DISPLAY
The SCL/SCM Remote Keypad has a three digit display like the
SCL/SCM drive.
The displays below are examples of the drive in RUN mode. On the
left, the drive is running at 43.6 Hz. On the right, the speed has been
changed to 52.8 Hz (during speed command changes, the upper left
decimal point turns on).
The displays below are examples of problems that will occur if the drive
is not properly programmed or if the keypad is not wired properly to the
drive.
Make sure Parameters
11, 12, and 14 are
properly set.
Make sure the keypad
is properly wired to the
drive and the cable is
away from noise.
