Hi John
Code 206 Battery voltage too low (<9v) Information sending from display.
Fault 257 Problem at safety relay output voltage at pin X1:24 is greater than voltage at pinX1:1. Reasons may be: shortcut to battery voltage at an output pin (e.g.brake pin X1.49.main contactor pin X1.2,valve pin etc) also check for broken wires upto brake soleniod.
Hope this helps let me know how you get on.
