Technical Service Bulletin โ 23V057
2/24/2023
APPLIES TO:
Specific Maintainer hydraulic cranes equipped with service/mechanics truck bodies produced from March 9, 2019 through February 8, 2023.
THE PROBLEM:
The affected units are equipped with an Eaton HFX20m CAN control module. The code/programming was designed in such a way that if power is removed from the R260 crane remote receiver, while the crane is being operated, the crane function may continue, without activation on the wireless remote by the customer.
THE REMEDY:
Maintainer will provide a software update to the HFX20m CAN control module free of charge to the customer.
PURPOSE:
To provide a software remedy that will prevent unintended or continued operation of the crane when not commanded by the operator.
Please read the entire document before proceeding with any work. Follow industry standards regarding safety equipment and procedures.
Chronology :
Maintainer was notified by a customer on 02/02/23 that he was rotating his crane from the wireless crane remote. The remote lost link, he released the rotate function button, but the crane continued to rotate. The customer found the receiver on the crane to have no power. Maintainer was able to duplicate on a test bench that if the function is active on the transmitter when power is removed to the receiver, crane function can continue, because it is supplied power from the list HFX20m programmable controller. Power Systems tested back to version 2.06 when the product was released and was able to duplicate the failure mode. An else statement in the function block of the code was missing, preventing the stop of function output. Maintainer decided to file a recall on 02/03/23 after in house testing was completed. No property damage or bodily injury has been reported and no warranty claims have been submitted.

Production Dates : MAR 28, 2019 – FEB 06, 2023
Description of Defect :
Description of the Defect : The service bodies with telescopic crane involved in this recall are equipped with a CAN system with Eaton components that are installed by Maintainer. Maintainer owns the custom written software that is coded and supplied by Power Systems Inc. When a crane function is being commanded by the Eaton
wireless transmitter, if power gets disconnected to the receiver on the Maintainer crane, crane operation may continue without wireless remote function being commanded by the user.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If signal is lost and crane movement occurs when not commanded by the user presents a safety risk and could potentially cause bodily injury or death and a potential to property damage. This would occur if the operator or other persons are in the swing radius of the crane. This situation can only exist when the hydraulic power supply (PTO powered by the chassis or auxiliary power unit is operated), and not while the service body is traveling down the road.
Description of the Cause : The program/code was written in a manner that allows the function to continue until it sees the next change of state signal. If the signal is completely
cut off, the function is latched on instead of off. Part 573 Safety Recall Report 23V-057 Page 2 Identification of Any Warning

Description of Defect :
Description of the Defect : The service bodies with telescopic crane involved in this recall are equipped with a CAN system with Eaton components that are installed by Maintainer. Maintainer owns the custom written software that is coded and supplied by Power Systems Inc. When a crane function is being commanded by the Eaton wireless transmitter, if power gets disconnected to the receiver on the Maintainer crane, crane operation may continue without wireless remote function being commanded by the user.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If signal is lost and crane movement occurs when not commanded by the user presents a safety risk and could potentially cause bodily injury or death and a potential to property damage. This would occur if the operator or other persons are in the swing radius of the crane. This situation can only exist when the hydraulic power supply (PTO powered by the chassis or auxiliary power unit is operated), and not while the service body is traveling down the road.
Description of the Cause : The program/code was written in a manner that allows the function to continue until it sees the next change of state signal. If the signal is completely
cut off, the function is latched on instead of off. Part 573 Safety Recall Report 23V-057 Page 2 Identification of Any Warning
that can Occur : There could potentially be no warning if the wiring harness to the crane receiver becoming damaged or disconnected while operating the crane.

Country : United States Chronology :
Maintainer was notified by a customer that he was rotating his crane from the wireless crane remote. The remote lost link, he released the rotate function button, but the crane continued to rotate. The customer found the receiver on the crane to have no power. Maintainer was able to duplicate on a test bench that if the function is active on the transmitter when power is removed to the receiver, crane function can continue, because it is supplied power from the list HFX20m programmable controller. Power Systems tested back to version 2.06 when the product was released and was able to duplicate the failure mode. An else statement in the function block of the code was missing, preventing the stop of function output.
