3.0 Warrior MU-9X15 Operation
3.1 System Startup
Startup depends on the type of Warrior handheld transmitter that the MU-9X15 receiver is
associated to. Refer to the Warrior transmitter manual for Startup details.
3.2 Associate the Warrior MU-9X15 with a Warrior Transmitter
Warrior system receivers and transmitters are associated (paired) before the system is shipped.
The Associate process is locked in the receiver by the MU-9X15 DIP switch 8 being set to 0
(OFF). The receiver will only communicate with transmitters it is associated to. When necessary,
other Warrior transmitters can be associated to the receiver as additional spares or to replace
damaged transmitters; but the receiver association ability must be first unlocked. Refer to the
specific Warrior transmitter for associate details.
3.3 Additional Warrior Programming Features
3.3.1 Horn/Light (Associate) Relay
Each Warrior receiver has a Horn/Light relay. Cervis, Inc. recommends properly wiring this relay
to some type of indicating device—such as a horn or light—that is easily recognized when
activated. When wired correctly, the operator will be alerted during the association process, and
the receiver communicating can easily be identified. The Horn/Light relay also identifies other
conditions.
Tilt Mode
If your Warrior transmitter has a Tilt Mode (see manual)—and it is tilted—the relay will begin
pulsing once per second after three seconds. The operator then has three seconds to correct the
tilt situation.
If the condition is not corrected in the three seconds that the relay is pulsing, the motion
outputs will be disabled; the crane should stop moving.
If the condition is corrected within the three-second period following the first indication of a
problem, normal crane operation resumes.
Low Battery Mode
When transmitter battery voltage drops to or below 2.2V (Low Battery Warning Mode), the
Battery LED (L2) begins flashing, and the Horn/Light relay energizes four times per minute
to alert you that the transmitter batteries need to be replaced with a fresh set.

Caution!
Replace transmitter batteries as soon as possible after the Low
Battery Warning begins. If the transmitter battery voltage drops to
2.0V, the transmitter shuts down and cannot be used until fresh
batteries are installed.
Associate Mode is Unlocked
If receiver DIP Switch 8 is in the unlocked position (1) when the receiver is powered on, the
Horn/Light relay will energize once to alert you to the unlocked Switch 8 position. Additional
transmitters can be associated with the receiver, if needed.
DIP Switch 8
The Horn/Light relay energizes once any time DIP Switch 8 is positioned from Off to On while
the receiver is under power.

Appendix A: Exposure to Radio Frequency Energy
Warrior transmitter units and receivers contain radio transceivers. When active, a transmitter
sends out radio frequency (RF) energy through its internal antenna. Warrior transmitters and
receivers comply with limits set by the United States Federal Communications Commission
(FCC) for operating distance from human tissue.
Appendix B: RF Exposure Considerations
The transmitter module may be used in a variety of host applications that fall into two general
categories:
1. Mobile: Any operating locations that are not on a human body. In mobile
applications, the host application is typically fixed to mobile equipment, with
either an internal or external antenna.
2. Portable: Operating locations where the transmitting equipment is located on the
hand, arm, or other part of the human body. In portable applications, the
equipment is typically held in an operator’s hand or affixed to either a belt or
harness on the torso.
Equipment containing the radio module was evaluated for RF exposure hazards by two
approaches:
1. Maximum Permissible Exposure (MPE) for mobile applications.
2. Specific Absorption Rate (SAR) for portable applications.
The required separation distances are measured from the actual location of the radiating part of
the antenna. An antenna may be inside the host application, affixed to the host application
enclosure, or at the end of an optional extension coaxial cable.
Mobile Applications
Equipment must be located at least 20cm away from areas likely to be occupied by an unaware
person.
Handheld Applications
All operators of handheld equipment with any type of antenna require proper equipment
operation training, and such training must include RF exposure safety instructions. Once training
is completed, they are considered to be “aware”persons.
If the portable operating position is on the hand or arm, a 5mm separation between the radiating
part of the antenna and nearby human tissue is required.
Required Training
All installers and operators of host applications that include an SRF310 FT module must be
trained to use proper RF safety precautions as presented in this section.

Appendix C: MU-9X15 Safety Circuit
Figure 8. MU-9X15 MLC Safety Circuit Logic Diagram
Figure 8 illustrates a high-level view of the system’s safety architecture. This architecture is
based around redundant enable signals that separate hardware circuits generate. The
microprocessor generates an enable signal to K14 when all conditions are met, and the user
activates the start sequence. The watchdog circuit generates an independent enable signal to
K15 as long as the microprocessor generates the proper signaling to the watchdog. Additionally,
these two independent enable signals are AND-ed together to enable an internal 12V bus that
supplies coil power to all relays
1
. The system cannot close any relay until both watchdog and
microprocessor enables are asserted. The loss of either signal immediately causes the MLC
path to open and all output relays to de-energize.
If there is a software fault in the microprocessor, the watchdog will not assert its enable output,
which will cause K15 to open. Additionally, this will disable the internal 12V bus, resulting in all
relay outputs returning to their non-active state, regardless of what the microprocessor is
commanding.
If there is a fault in the watchdog circuit that causes its output to never assert, the unit will be
safe as the MLC path cannot close because K15 will be open and the internal 12V bus will be
disabled. If the fault causes the watchdog circuit to never de-assert (perhaps the contacts on
K15 weld closed), the system is still safe because the microprocessor has independent control
of K14 that can break the MLC path and internal 12V bus.
This architecture was devised so that any one fault will not cause loss of control of the MLC
path.

Except the K13 H/L relay because it is necessary to operate the H/L when the MLC is open.
