Dynatest FWD - Lock Error and Plate Not Low Error

5.3 “Lock error” and “Plate not low error”
If you forget to release one of the plate subassembly transport locks and you press the LP/RW
button to lower the plate, then the lowering will stop, when the PL LED turns off (while PH
LED is still on), i.e. the LP/RW button will become inactive. RP button will still be active, so
that the plate can be re-raised to enable releasing of lock(s).
Also, for smaller drop weight setups, the weight MAY start raising (slowly) during lowering
of the plate using the LP/RW button. If this causes the TG LED to turn off before the PL
LED, then it will not be possible to lower the plate further. In that case, use the LC button to
return the weight and try again (perhaps use DROP (LP/RW + red button) to lower the plate,
until the PL LED turns off).
So, if the LP/RW button will not work, then always check that the PH, PL and TG LEDs do
NOT fulfil any of the following, erroneous combinations (x means don’t care):
PH
PL
TG
“Lock Error”:
