TROUBLESHOOTING
Posioning System Faults
Error Descripon Cause
F.752
Timeout with protocol
transmission.
‒ Interface cable defecve / interrupted.
‒ Absolute encoder processor electronics
defecve.
‒ Defecve hardware or electrically noisy
environment.
‒ To resolve, use a shielded control cable and/or.
adjust an RC element (100Ω +100nF) at the
brake.
F�760
Posion outside of window. ‒ Posion encoder drive defecve.
‒ Absolute encoder processing electronics
defecve.
‒ Defecve hardware or electrically noisy
environment.
‒ Encoder baery dead.
F�761
Distance Channel 1 <->
Channel 2 outside allowed
window.
‒ Posion encoder drive defecve.
‒ Defecve hardware or electrically noisy
environment.
F�762
Electronic limit switch
posions incorrect.
‒ Upper limit switch E0 or intermediate limit
switch E1 has exceeded the valid limit range.
‒ Controller not yet inialized.
‒ Posion values during calibraon not correct or
values are no longer valid.
F�763
DES-B Error Posion encoder drive defecve -> make a reset.
F�770
Gate transmission rao is
set too high.
The value of Parameter P�202 is not 13.
F�7A2
Communicaon failure
between COM boards.
Soluon is to add ferrite cores at either end of cable; twist
cable ve mes (or more, as required) around ferrite.
Error F�7A2 may occur when there is a communicaon error between primary and secondary gate
controllers commonly caused by noise; i.e., electromagnec interference (EMI) from other sources.
The recommended soluon to this problem is to apply EMI shielding. SpeedGate factory installaons that
occurred aer March 2023 may already include electromagnec interference shielding (Ferrite EMI Cable
Core - Laird Part Number LFB259128-000), available through Wallace Perimeter Security.
