Cervis, Inc. Safety Precautions
Read and follow all instructions.
Failure to abide by Safety Precautions may cause equipment failure, loss of authority
to operate the equipment, and personal injury.
Use and maintain proper wiring. Follow equipment manufacturer instructions.
Improper, loose, and frayed wiring can cause system failure, equipment damage, and
intermittent operation.
Changes or modifications made to equipment not expressly approved by the
manufacturer will void the warranty.
Equipment owner/operators must abide by all applicable Federal, State, and Local
laws concerning equipment installation and operation. Failure to comply could result
in penalties and could void user authority to operate the equipment.
Make sure that the machinery and surrounding area is clear before operating. Do not
activate the remote control system until certain that it is safe to do so.
Remove power from the base unit before attempting any maintenance. This will
prevent accidental operation of the controlled machinery.
Remove power from the base unit by detaching the 12-pin cables from the base unit
connectors P1 and P2, or by removing the source power from the circuit.
Use a damp cloth to keep units clean. Remove mud, concrete, dirt, etc. after use to
prevent obstructing or clogging the wiring and switches.
Do not allow liquid to enter the base unit enclosures. Do not use high-pressure
equipment to clean the base unit.
Disconnect the base unit before welding on the machine. Failure to disconnect the
base unit may cause destruction of or damage to the base unit.
Operate and store units only within the specified operation and storage temperatures
defined in this document’s specifications.

1.0 SmaRT BU-xH6R Base Unit
The SmaRT BU-xH6R Base Unit features six Form C relay outputs. Each Form C relay contact
can switch up to 8 amperes at 250 VAC or VDC. Using Direct Sequence Spread Spectrum
(DSSS) wireless technology at 900 MHz or 2.4 GHz, the base unit robustly links with a handheld
remote control unit in congested radio environments at extended ranges. All controlled
apparatus connections—and base unit power—are made using two cables with keyed, heavy
duty 12-pin connectors, through which output signals are also ported. Five status/diagnostic
LEDs shown in Figure 1 below determine the state of the unit.
Figure 1. BU-xH6R LEDs
BU-xH6R Input Power
Input power depends on the type of BU-xH6R used:
BU-xH6R-xxx-HVU accepts input voltage of 100–240VAC @ 47–440Hz, or 120–370VDC.
The –HVU power option uses a universal converter that can accept either high-voltage AC
or DC input. The converter is not polarity sensitive.
BU-xH6R-xxx-LVD accepts 7–32VDC.
The –LVD option is polarity sensitive to:
Enhance low input voltage behavior.
Prevent resets—due to sagging battery voltage when an engine is started—from
occurring.
BU-xH6R-xxx-LVA accepts 7–28VAC, 50/60Hz.
The –LVA option permits operation using readily available step-down control voltage
transformers for power.
An optional Controller Area Network (CAN) interface feature is available for networking multiple
base units in more complex control applications. Contact Cervis, Inc. for more information.
An RS-232 interface is available for use with SmaRT Connect. Due to pin limitations, it is not
available if the CAN option is selected.

1.1 Base Unit Installation
Caution
During installation, make sure the machine that the base unit will be attached to
is disabled.
Use the configuration diagrams supplied by Cervis, Inc. to guide you in mounting the base unit
and connecting your wiring harness cables. Base unit mounting is left much to your discretion
with the following guidelines:
Before installing, make sure that the configuration diagrams supplied with the system are
available. Keep them where they are available at all times.
Make sure the wiring harness cables are on hand.
Always mount the receiver away from any intense radio or electric disturbance sources.
Make sure the mount is secure. Mount the unit where you have enough room for your
wiring harness connections.
If exposed to rain or low-pressure water jets, Cervis, Inc. recommends installing the base
unit as shown, with the connectors down. Plus, a drip-loop formed with the cables is a
good-practice recommendation.
Caution
The base unit enclosure and connectors are NOT rated for high-pressure
washing. Doing so could damage the base unit or connectors.

1.2 Optional Antenna Extension Installation
Both the 10-ft. and 3-ft. antenna extension cables are compatible with 2.4GHz and 900MHz
antennas. The antenna example shown in Figure 4 is a 2.4GHz antenna.
Figure 4. Antenna Extension Kit Installation
Make sure the antenna is located in clear line-of-sight of
the remote.
1. Loosen and remove extension cable nut to allow the
antenna ferrule to push through a mounting hole
(user discretion).
2. Rethread the nut to secure the ferrule to the device.

1.3 BU-xH6R Wiring
Figure 5. Dual Connectors/Pin Numbers (enhanced)
Caution
If the base unit supply voltage drops below a minimum volt level—even
momentarily—the unit will reset. Minimum supply voltages are:
7VDC for a BU-xH6R-xxx-LVD
7VAC for a BU-xH6R-xxx-LVA
90VAC or 100VDC for a BU-xH6R-xxx-HVU
If the supply voltage drops below minimum input volts for a consistent period of time,
the LEDs (including the TX/RX LEDs, if transceiving) will dim and flicker.
These circumstances are symptoms of a battery or power source that cannot sustain
the present current load. Remedy this situation as soon as possible.

1.4 External Protection Devices for Relay Contacts
Depending on the model, the BU-xH6R may have internal snubbing circuits to protect the relay
contacts. (See Table 4, AC Sup.) Each snubber consists of a 47Ωresistor in series with a 0.1 µF
capacitor across each relay contact. However, the internal snubbers may not be adequate for all
loads and applications. An MOV—or Metal Oxide Varistor—is a protection device used to
suppress high-transient voltages that can cause relay contact deterioration, especially when
switching inductive loads such as solenoids or relay coils. They protect circuits against
excessive transient voltages by clamping the voltage to a safe level and dissipating the
unwanted energy. To provide proper protection, the MOV must have a voltage rating and an
energy dissipation rating appropriate to the application. Other devices—such as power Zener
diodes or R-C snubbers—may be necessary, depending on the application and whether the
switched circuits are AC or DC.
When using contactors or solenoids with SmaRT systems, Cervis, Inc. advises using external
protective devices by connecting them across the coils as shown in the examples below using
MOVs.
Figure 7. Typical MOV and Suggested MOV Wiring Across the Contactor Coils
In some applications, internal snubbers may not be desired. (See Table 4, AC Sup.) The –NOS
option can be specified to omit them. However, this can leave the contacts vulnerable to
switching transients and arcing. Contact Cervis, Inc. Customer Service for assistance in
choosing appropriate contact protection.
1.5 Standard Configuration
Output Check/Operating Mode Interlock
In the default output configuration, there is an interlock that prevents an output from activating if
an adjacent handheld button is pressed at the same time as the intended button. Once the
remote is associated to the base unit (see Appendix C), outputs—when properly wired—respond
and are indicated by the base unit OUT (output) LED as listed in Table 2.

Caution
Push-To-Operate (PTO) means that the outputs under control should only change
states when the appropriate handheld button is pressed, and then only for the
duration of time that particular output button is pressed. Investigate any unexpected
motion that occurs when pressing the handheld output control buttons.
Should a jerkiness of motion occur while constantly pressing an output button,
immediately stop operation. Check the OUT LED and the other BU-xH6R diagnostic
LEDs for any indication of a problem.
Be aware that even if the handheld and base unit diagnostic LEDs do not indicate a
problem, one may be present and further troubleshooting steps may be needed.
If a problem is found, do not operate the SmaRT System until the problem is
resolved.
