7.0 TROUBLE SHOOTING
SYMPTOM
Leaks
Elevation Binding
Horizontal Rotation Binding
One Axis Fails To Operate
From Any Control Station
Vertical/Horizontal axis will not
speed up
No Power light
Power Light On But No
Operation
Operation only from monitor
operator station. STOW, &
OSC Light’s on remote station
blink slowly when button
pressed.
Monitor will not operate from
any station and STOW & OSC
light’s on monitor are on solid.
Operation only from monitor
control station
Vertical/Horizontal axis runs
only in fast speed
Vertical/Horizontal 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
Incorrect wiring
Bad communication board
Communication board code version incompatible
Loose motor wiring connection
Bad
control board
Bad motor
Bad membrane switch
Loose encoder wiring connection
Bad motor encoder
Polarity reversed
Low voltage due to:
- wire gauge too small
- wire length too long
- poor connection
- inadequate apparatus electrical system
Bad communication board
motor
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
Check blue/white communication wiring
Replace communication board in monitor. If problem
persists, replace communication board in remote operator
station.
Replace communication board in monitor.
Verify code versions on monitor and all operator stations
Check axis motor connection
Interchange motor control boards and check if problem
persists with same axis, If not, replace motor control
board.
Interchange motor control boards. Check if problem
persists with same axis, If yes, replace motor.
Replace membrane switch / operator station
Check axis encoder connection
Interchange motor control boards. 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 motor control boards. 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 motor control boards. Check if problem
persists with same axis. If yes, replace motor.
