31.110 – AC Compact Style
with Micro-Controller
Hubbell Radio Control Systems use the latest
micro-controller technology and ultra reliable
Manchester II (bi-phase) digital FM signal
coding. Each radio control system operates on a
licensed frequency in the 72 to 76 MHz or the
450 to 470 MHz bands.
The security of any remote control system is of
the utmost importance. Hubbell radio control
systems’ security is enhanced through multiple
checks before any function can become
operational:
31.120 – DC Compact Style
with Micro-Controller
• The received signal must be of the proper
frequency.
• The received message must have the proper
address and must be in the correct format.
• The receiver calculated CRC code must be
identical to the CRC code calculated by the
transmitter and sent as part of each message.
• The preceding items must be met and all
transmitter lever switches must be centered
before the Crane Main Contactor can be
energized.
• To continue or change an energized function,
requires the receipt of a “valid message”
prior to timeout of the message timer. If no
valid message is received, the system turns off
all outputs.
31.130 AC License-Free
with Belt-Clip Transmitter
• Two separate “watchdog timers” assure that
all outputs are switched off in case of a
receiver malfunction.
HUBBELL
Radio Crane Control Systems
A typical radio crane control system consists of a portable transmitter carried by the
operator, and a receiver installed on the crane. Each system operates on a licensed
frequency in the 72 to 76 MHz or the 450 to 470 MHz bands.
The receiver is crystal controlled. A synthesized receiver is an option for 72–
76 MHz. An 8-bit micro-controller, operating at 4.9 MHz, decodes the signal
coming from the rf module and passes the output commands through the I/O boards
to the output modules.
The ac receiver uses 120V ac Solid State Relay output modules. No interface relays are
needed for controllers up to and including size 4 contactors. An LED shows the status of
the output module. A stepless, analog output module is available, as is a relay card
using electro-mechanical output relays. Input modules monitor the status of the 120V ac
Control Power, Main Contactor, plus M, F, R for each motion.
The output modules on the dc receiver are 270V dc Solid State Relays. No interface
relays are needed for controllers up to and including size 5 contactors. The output
module status is shown by LED’s: red = output activated; green = output current flowing.
Input modules monitor the status of the 250V dc Control Power, Main Contactor, plus M,
F, R for each motion.

backed real time clock
Each transmitter/receiver pair has their own unique 7–bit address code (the first seven
bits of the digital message). Unless the transmitter address and receiver address are
identical, the system will not respond to any command, regardless of the frequency.
Message integrity is assured by use of an 8-bit Cyclic Redundancy Check (CRC)
code. Cyclic redundancy check is a division performed in the transmitter logic,
which produces a remainder that is transmitted last as the 8-bit check code. The
receiver logic performs a like division on the received message (without the CRC) to
produce its own 8–bit CRC code. If the two CRC codes are identical, the received
message will be decoded as a “valid message” and the appropriate outputs will be
turned on or off, as directed.
The crystal controlled transmitter uses an 8-bit micro-controller, operating at 2.5 MHz, to
scan the command switches. All major function switches must be in the center or “off”
position before the Crane Main Contactor can be energized. When the transmitter is
“on” and the command switches are “off” or centered, then the transmitter actually sends
a “stop” command to the system. Motion can occur only with the removal of the “stop”
command and the addition of a speed point/directional command within a certain time
sequence. Using the key-switch to turn off the transmitter power causes the transmitter to
send five consecutive “E-STOP” messages before shutting down.
The switch position data is transmitted as a digital signal at the licensed frequency, using
Manchester II coding. The digital message has a specific format and is repeated 2 to
9 times per second. The repeat rate is programmable. The transmitter is turned off
between messages to conserve battery life and rf spectrum. This makes it possible to
have several transmitters operating in the same area, on the same frequency, with
practically no interference because of the different transmission rates. The unique address
code of each transmitter and receiver assures that only the matching receiver responds to
the radio commands. All other signals on the same frequency are ignored.
The use of Manchester II (bi-phase) digital FM signal coding makes the message less
sensitive to corruption from interference. Please consult Tech Info 31.100, page 2, for a
detailed discussion on the message format and Manchester II coding.
