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.

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...
