REMOTE KEYP AD INSTRUCTIONS

The SM-Plus Series Remote Keypad option allows the SM-Plus 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 SM-Plus drive,
the remote keypad has Start/Stop and Forward/Reverse functions.

2. SM-PLUS REMOTE KEYP AD 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. The dotted line is the
outline of the remote keypad.

NOTE: The Remote Keypad option will only work with SM-Plus drives that
have parameter version “309” or “312”. It will not work with SM-Plus
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 SM-Plus Installation and Operation
Manual for information on OEM Default settings.

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 gage minimum) wire only.

5. SETTING UP THE SM-PLUS DRIVE

Y

There are three possible control scenarios when using the remote keypad:

1. The remote keypad is used for Start/Stop control, Forward/Reverse
selection, programming, and monitoring.

2. The remote keypad is used for programming and monitoring, but the
drive’s terminal strip is used for Start/Stop control and Forward/Reverse
selection.

3. The remote keypad is used for programming and monitoring, while
Start/Stop control and Forward/Reverse selection can be toggled
between the remote keypad and the drive’s terminal strip.

In all of the above scenarios, speed is controlled from the remote keypad
unless another speed reference source is selected.

NOTE 1: The STOP key on the remote keypad will work even if the
terminal strip is used for Start/Stop control.

1. REMOTE KEYPAD TO PROGRAM, MONITOR AND
CONTROL

a. Set Parameter 14 (CONTROL) to “02” (REMOTE KEYPAD

ONLY).

b. Install a jumper between terminal TB-1 and TB-2 on the drive’s

terminal strip.

2. REMOTE KEYPAD TO PROGRAM AND MONITOR, AND
TERMINAL STRIP TO CONTROL.

a. Set Parameter 14 (CONTROL) to “03” (TERMINAL STRIP OR

REMOTE KEYPAD).

b. Wire the Start/Stop and Forward/Reverse circuits to the drive’s

terminal strip according to the SM-Plus manual.

3. TOGGLE CONTROL BETWEEN REMOTE KEYPAD AND
TERMINAL STRIP

a. Set Parameter 14 (CONTROL) to “03” (TERMINAL STRIP OR

REMOTE KEYPAD).

b. Choose either Terminal 13A or 13C on the drive as the input that

will toggle between remote keypad control and terminal strip control.

To use TB-13A, set Parameter 10 (TB-13A FUNCTION SELECT) to
“08” (REMOTE KEYPAD).

To use TB-13C, set Parameter 12 (TB-13C FUNCTION SELECT) to
“07” (REMOTE KEYPAD).

c. Wire a selector switch or relay contact between TB-13A or TB-13C

(whichever was programmed for REMOTE KEYPAD in Step b
above) and TB-2 on the drive’s terminal strip.

d. Wire the Start/Stop and Forward/Reverse circuits to the drive’s

terminal strip according to the SM-Plus manual.
NOTE: If a 2-wire Start/Stop circuit is required, use the Alternate 2­Wire circuit described in Section 11.3 of the SM-Plus manual.

To select the Remote Keypad as the control source, close TB-13A or TB­13C (whichever was programmed for REMOTE KEYPAD) to TB-2.

To select the terminal strip as the control source, open TB-13A or TB-13C
with respect to TB-2.

NOTE 2: When the remote keypad is selected for Start/Stop control,
terminal TB-1 on the SM-Plus drive must be closed to TB-2 to allow the
drive to run. TB-1 is a Stop input and it is always active. If it is open with
respect to TB-2, the drive will not run.

6. REMOTE KEYP AD FUNCTIONS

The M key and the ▲ and ▼ keys on the remote keypad function the same
as the Mode button and the ▲ and ▼ buttons on the drive. The other
remote keypad functions are described below:

Reverse/Forward key: Selects Forward or Reverse direction.

RF

RUN

STOP

The R/F key is only active if Parameter 17 - ROTATION is set
to “2” (FORWARD AND REVERSE).

When the R/F key is pressed, the symbol for the opposite
direction will blink on the display. Press the M key within four
seconds to confirm the rotation change.

Below are the display symbols used to indicate direction:

FORWARD REVERSE

RUN key: Press RUN to Start the drive. The RUN key is only
active if the remote keypad is selected as the Start/Stop control
source.

STOP key: Press STOP to Stop the drive. The STOP key is
active whenever the remote keypad is operational, even if the
remote keypad is only used for programming and monitoring.

7. TROUBLESHOOTING

CONDITION / DISPLA

Remote Keypad display
is blank.

Remote Keypad
and/or SM-Plus
drive displays “JF”

The RUN key does not
work to start the drive.

The R/F key does not
work to change rotation
direction.

Parameter 14 - CONTROL is set to “01”
(TERMINAL STRIP ONLY)

The Remote Keypad is not wired correctly to the
drive.

JF is a serial fault, which indicates a communi­cation problem. Check for proper wiring between
the remote keypad and the drive.

A “JF” fault will also occur if an attempt is made
to power the remote keypad and an ausiliary
relay from TB-11. See Note 2 in Section 4.

T o start the drive using the RUN key, the
Remote Keypad must be selected as teh control
source, and TB-1 must be closed to TB-2 on the
drive’s terminal strip. Refer to Sections 4 and

5.relay from TB-1 1. See Note 2 in Section 4.
T o use the R/F key to change rotation direction,

the remote keypad must be selected as the
control source, and Parameter 17 (ROTA TION)
must be set to “02” (FORWARD AND
REVERSE). Refer to Sections 4 and 5.

POSSIBLE CAUSES

If the remote keypad display is totally blank or is displaying a “JF” fault, the

WARNING!

STOP key WILL NOT stop the drive. The remote keypad must be
operational in order for the STOP key to be active.
