Command Center Deadman Port Fix - June 16th, 2023

COBRA was made aware of a possible hardware fault with the COBRA Command Center. While this fault only applies to Command Center units that are utilizing the Deadman Control feature, it is advisable that all owners of the Command Center apply this fix. The issue relates to a loose lock washer potentially coming in contact with exposed wire pins that could cause for an inadvertent firing issue.

What is the concern?

In rare cases, the washer that is placed between the nut and the side of the Command Center case can come loose and make contact with exposed pins on the Deadman harness. If the Deadman harness is connected to the 18R2 within the Command Center it has a possibility to short the two pins that control the STEP function of the 18R2.
