HPO-6700 Series Output Override Boards
Installation Guide
KMC Controls, 19476 Industrial Drive, New Paris, IN 46553 /877.444.5622 /Fax: [phone] /www.kmccontrols.com
INTRODUCTION
 The HPO-6704 converts a standard analog
voltage output to a 4–20 mA output while
providing an adjustable potentiometer for
override settings while in the “Hand” position.
NOTE: The HPO-6704 board supplies the
power and will not work with a 4–20
mA device that also supplies its own
power.
Each output board has a red LED indicator that
turns On when the board’s output is turned On
either manually or automatically.
Output boards have an accessible three-position
slide switch for selecting the “Hand-Off-Auto”
functions:
 While in the H (“Hand” or manual On) position,
the output is manually energized, and the
controller is provided with a feedback signal to
indicate the output has been overridden.
 While in the O (Off) position, the output is
manually de-energized, and the controller is
provided with a feedback signal to indicate the
output has been overridden.
 While in the A (Auto) position, the output is
under the command of the controller.
NOTE: An HPO-670x-1 is always in auto mode
and does not have the manual slide
switch.
NOTE: HPO-6701 triac and HPO-6703/6705
relay circuits use the Switched
Common SC terminal—not the Ground
Common GND terminal.
NOTE: HPO-6701 triac outputs are for 24 VAC
only.
NOTE: Only the HPO-6701triac and HPO-
67044–20 mA boards are approved
for smoke control applications. For
smoke control application information,

For enhanced controller output options (such
as manual control, using large relays, or for
devices that cannot be powered directly from a
standard output), install output override boards
(in compatible controllers). The following types of
override boards are available:
 The HPO-6702 enhances the analog voltage
output with a “Hand-Off-Auto” control while
providing an adjustable potentiometer for
override settings while in the “Hand” position.
 The HPO-6701/6703/6705 boards are
designed to convert a binary/digital output
to a relay contact or triac output and to
provide “Hand-Off-Auto” control and feedback
functions.

035-08 (BACnet) and/or 000-035-09
(KMDigital).
CAUTION
Connecting 24 VAC or other signals that
exceed the operation specications of
the controller before an override board
is installed will damage the controller.
For HPO-6700 series specications, see the data
sheet at kmccontrols.com.
See the sections below for installation into the
particular type of controller.
 For KMC Conquest BAC-5900 series
controllers and CAN-5901 expansion modules,
see Conquest Controllers/Modules on page
2.
 For older controllers with “top-mounting”
raised plastic cases (BAC-5801/5802 and
newer KMD-5801/5802s), see Older “Plastic”
Case Controllers on page 3.
 For older controllers with metal (e.g., BAC-
5831, BAC-A1616BC) and older “side-
mounting” plastic cases (older KMD-
5801/5802s), see Older “Metal” Case
Controllers on page 4.
CONQUEST CONTROLLERS/MODULES
These instructions apply to KMC Conquest BAC-
5900 series controllers and CAN-5901 expansion
modules (with a flip-open lid).
1. Disconnect the power by removing the black
power terminal block.
2
2. Pull the top edge of the (translucent black)
override board cover away from the case and
flip open the cover.
3. Remove the jumper from the slot in which the
override board will be installed.
3
NOTE: Each of the eight override slots ships
from KMC with a jumper installed on
the two pins closest to the output
terminal blocks. Only remove a jumper
if an override board will be installed.
4. Orient the override board with the HOA
selection slide switch toward the top of the
controller.
5. Slide the override board into the slot in which
the jumper was removed.

1. Disconnect the power by removing the power
jumper or terminal block.
2. Remove the cover by squeezing on both sides
of the cover and lifting it off.
3. Remove the jumper from the slot in which the
override board will be installed.
NOTE: Each of the override slots ships from
KMC with a jumper installed on the
two pins closest to the output terminal
blocks. Only remove a jumper if an
override board will be installed.
4. Orient the override board with the HOA
selection slide switch toward the top of the
controller.
5. Slide the override board into the slot in which
the jumper was removed.
6. Close the plastic cover.
7. Move the A-O-H selection switch on the
override board to the appropriate position.
NOTE: A = Automatic (upper position).
O= Off (middle position).
H= Hand/On (lower position).

NOTE: For more information about output
override boards, see the installation
guide for the HPO-6700 Series.
8. Repeat Steps 3 through 7 for all other desired
boards.
9. Wire the output device to the corresponding
green (output) terminal block of the override
board. (See Wiring on page 4.)

OLDER "METAL" CASE CONTROLLERS
These instructions apply to controllers with
metal (e.g., BAC-5831, BAC-A1616BC) and older
“side-mounting” plastic cases (e.g., older KMD-
5801/5802). After installation of the boards, the
existing slot cover needs to be replaced by a
raised HPO-6802 output board cover.
To install the HPO-6700 series override boards:
1. Disconnect the power by removing the power
jumper or terminal block.
2. Remove the relevant slot cover(s) by lifting the
right-hand side of the cover (within the plastic
frame) toward you.
3. Remove the jumper from the slot in which the
override board will be installed.

NOTE: The 4–20 mA HPO-6704 board
supplies the power and will not work
with a 4–20 mA device that also
supplies its own power. For 4–20 ma
applications, see also the 4–20 mA
Wiring for Controllers Application
Guide.
NOTE: If a board is removed from a slot,
reinstall the (HPO-0063) jumper
(previously removed) on the two pins
closest to the outputs. The jumper
enables the analog voltage output on
the terminals.
NOTE: Switched Common (SC) output
terminals are unconnected in these
model controllers unless an appropriate
override output board is installed. Use
only the Switched Common instead of
Ground with the HPO-6701 triac and
HPO-6703/6705 relays. Use the SC
terminal in the same output bank as the
output terminal. See Grounds Versus
Switched Commons on page 6.
CAUTION
Connecting 24 volts AC or other
signals that exceed the operation
specications of the controller to the
output before the output jumper is
removed will damage the controller.
Remove the jumper and install the
override board before connecting AC
or other voltage to the output of the
controller.

MAINTENANCE
No routine maintenance is required. Each
component is designed for dependable, long-term
reliability and performance. Careful installation will
also ensure long-term reliability and performance.
GROUNDS VERSUS SWITCHED COMMONS
Switched Common (SC) output terminals are unconnected
in the controller unless the jumper is removed and an
appropriate relay/triac override output board is installed.
Use only the SC instead of Ground with the HPO-6701 triac
and HPO-6703/6705 relays!
Use the SC terminal in the same output bank (individual
terminal block) as its output terminal. The switched
common terminals are isolated from the circuit grounds
used for the universal output analog circuitry in
controllers.
For samples of wiring to output devices, see Wiring on
page 4.
