Product safety notification

There is a potential safety risk when using the acknowledgement button of the SINUMERIK mini handheld unit (6FX2007-1AD03 and 6FX2007-1AD13). The third stage of the acknowledgement button (when pushed all the way down) can malfunction. We urgently request that all customers who have the mini handheld unit check their devices against the serial numbers that have been published below and when required, immediately contact the specified contact person.

Current deliveries of these units are not involved and are therefore safe.

SINUMERIK mini handheld unit / product safety notification



EUCHNER GmbH + Co. KG, Germany – the supplier for the SINUMERIK mini handheld unit has informed Siemens of a potential safety risk involving the acknowledgment buttons that were in the past integrated in the SINUMERIK mini handheld units (mini HHU). Stage 3 of the pushbutton (when pressed all the way down) does not reliably open the switching contacts. This means that it cannot be guaranteed that the circuit is reliably interrupted.

In the worst case, there is a risk of severe bodily injury - even death.
