Fault finding guide
If the quide below suggests new configuation use the S111SX Node Manager to configure
the unit.
No operation possible
v
If green “RUN CPU” LED H2 is off check mains fuse F1 located on
the relay board. The unit is also equipped with resettable overload
components - disconnect from mains supply and allow the unit to
cool down for a few seconds.
v
If yellow “LON” LED H1 is on or blinking the unit is unconfigured.
v
Check the network cable connections and network termination.
No or intermediate Pan- and/or Tilt operation
v
Check that the unit is configured for the actual pan & tilt head.
v
Check the wiring for short-circuits or broken wires.
v
If one function only is failing try to swap the pan and tilt wiring to
determine the fault location. If e.g. the tilt initially was faulty
connect the tilt wires to the pan output and try to operate the tilt
by activating the pan function. If inoperative still the pan & tilt
head is faulty - if operative now the output is overheatet or
defective.
v
The outputs are overload protected - disconnect from the mains
supply and allow the unit to cool down for a few seconds.
No or slow Zoom- and/or Focus operation
v
Check the wiring for short-circuits or broken wires.
v
If one function only is failing try to swap the zoom and focus
wiring to determine the fault location. If e.g. the zoom initially
was faulty connect the zoom wires to the focus output and try to
operate the zoom by activating the focus function. If inoperative
still the lens is faulty - if operative now the output is overheatet or
defective.
v
If running too slow or fast reconfigure the lens setup.
Pre-positions cannot be found, are in-accurate or drifting
v
Check the wiring for short-circuits or broken wires. Check
feed-back potentiometers fitted in the pan & tilt head and lens
electrically and mechanically. Note, that most potentiometers
wear out in 4-18 months if used on a 24-hour tour basis.
v
Cables are too long or exposed to excessive noise. Refer to the
Pan & Tilt head connection
section for possible solutions.
