Hi everyone. I am having a problem when I hold the deadman switch to jog the robot. I receive event message 90224, and the system goes into SYS HALT. When I check the safety signals on the FlexPendant, EN1 changes to 1, but EN2 does not. Can you help me fix this  
Notes ;  
my fp cable it’s already damage

you’re missing a channel. If your cable got damage I would try to repair or replace the cable.  
But it can also be the switch inside the flexpendant or connectors.
