7.0 TROUBLE SHOOTING
SYMPTOM
Leaks
Elevation Binding
Horizontal Rotation
Binding
No Power LED
Power LED On But No
Operation
Operation only from
monitor control station
One Axis Fails To Operate
From Any Control Station
Vertical/Horizontial axis
will not speed up
Vertical/Horizontial axis
runs only in fast speed
Vertical/Horizontial axis
only runs ~5 seconds and
then stops.
POSSIBLE CAUSE
Debris or damage in seal area
Debris or damage to elevation drive parts
Lack of lubricant
Debris or damage to horizontal drive parts
Lack of lubricant
Polarity reversed
Low voltage due to:
- wire gage too small
- wire length too long
- poor connection
- inadequate apparatus electrical system
Incorrect wiring
Communication board code version
incompatible
Loose motor wiring connection
Bad control board
Bad motor
Bad membrane switch
Loose encoder wiring connection
Bad motor encoder
Loose encoder wiring connection
Bad motor encoder
Loose encoder wiring connection
Bad motor encoder
REMEDY
Clean out debris or replace damaged parts
Clean out debris or replace damaged parts
Grease, see section 8.1
Clean out debris or replace damaged parts
Grease, see section 8.1
Check wiring and reverse polarity
Check connections and wiring per section 5.1.2
Check blue/white communication wiring
Verify code versions on monitor and all operator
stations
Check axis motor connection
Interchange control boards and check if problem
persists with same axis, If not, replace control
board.
Interchange control boards and check if problem
persists with same axis, If yes, replace motor.
Replace membrane switch / operator station
Check axis encoder connection
Interchange control boards and check if problem
persists with same axis. If yes, replace motor.
Remove encoder cover and check for RED light just
below disk. If no light, encoder is bad. Replace
motor.
Check axis encoder connection
Interchange control boards and check if problem
persists with same axis. If yes, replace motor.
