8-2 Troubleshooting
8.4 Basic System Troubleshooting
8.4.1 System Power
Table 8-1 System Power Troubleshooting
Symptom Possible Cause Recovery
No power to major system
components
The ON (l) button has not been
pressed
Press ON (l) on the front panel. The green button
will flash for 60 seconds and then the machine will
turn on.
Main power cable
disconnected
Connect the main power cable to an AC power
source.
Main power circuit breaker
turned OFF
Turn ON the main power circuit breaker at the rear
of the system.
A circuit breaker has been
tripped.
The SL-940E/SL-941E incorporates circuit
breakers with a “push to reset” feature rather than
fuses. For detailed troubleshooting of power
related issues, consult the power manager block
diagram or call Asymtek Technical Support.
EMO button has been
activated
1. Turn the EMO button clockwise until it
pops out. The EMO buttons at the front and
rear of the system interrupt power to all power
connections except
the laptop computer.
2. Press ON (l) on the front panel.
Interlock circuit is interrupted
Make sure the hood is closed. The interlock places
the servo control system in a low power state that
is just sufficient to hold the positioner in place for
syringe changes. Opening the front hood does not
completely power down the SL-940E/SL-941E, and
does not power off the PC.
Spill pan not in place
The spill pan must be in place for proper
ventilation. A spill pan interlock sensor detects
proper installation. If the spill pan is not in place,
the system will not operate.
Machine Exhaust Ventilation
not ON
Make sure exhaust vent duct is connected to the
factory exhaust system ductwork according to
specifications.
(600 scfm air at 1 in. water column static pressure)
Power control cable
disconnected
Verify the power control cables are properly routed
and connected from the Power Manager to the
front panel switches.
Button failure Call a trained service technician.
Applicator does not
operate.
Loose fluid, or electrical
connections; restricted hoses
Call a trained service technician.
Micro-adjust knob is fully
closed
Open micro-adjustment to characterized setup
value (value between 1 and 12 marks of turn).
Applicator ON/OFF switch is
OFF
Turn Applicator ON/OFF switch to the ON position.
Air to applicator is
disconnected or connected to
the wrong quick disconnect
Reconnect air line from applicator to quick
disconnect on Z-head.
Safety Interlock fails to
reset.
Interlock Activated
Make sure the hood is closed and the spill pan is in
place. If the interlock still fails to reset, call a
trained service technician.
Troubleshooting 8-3
8.4.2 Pneumatics
Table 8-2 System Pneumatic Troubleshooting
Symptom Possible Cause Recovery
No air pressure
System not connected to facility
air supply
Connect the main air inlet to a facility air supply.
Main air regulator off Verify main air regulator is set properly.
Reservoir air regulator off
1. Check reservoir air; secure connections if
necessary.
2. Verify reservoir air regulator is set properly.
No fluid pressure
Nozzle is clogged
Remove nozzle, visually verify that it is clogged.
See the applicable coating applicator manual for
cleaning instructions.
Not enough fluid pressure or no
fluid pressure
Increase fluid pressure. If equipped with material
change over option, verify valves are set to correct
reservoir.
Micro-adjust knob is fully
closed
Open micro-adjustment to characterized setup
value (value between 1 and 12 marks of turn).
ECXP not started Start ECXP.
8.4.3 Conveyor
Table 8-3 Conveyor Troubleshooting (
Symptom Possible Cause Recovery
Chain will not move
EMO button has been activated
1. Turn the EMO button clockwise until it pops
back into position.
2. Press
ON (l) on the operator’s console.
Conveyor Controller malfunction Call a trained service technician.
Stop pins, board pins, or
bar clamps do not work.
Air pressure too low
Check main air pressure (80 to 90 psi) and
conveyor air pressure (30 to 40 psi).
No upstream or
downstream interface.
Varies Call a trained service technician.
Part sensor not sensing
when board is present.
Sensor is dirty, not active, or
needs to be adjusted
Clean part sensor, check sensor I/O, or adjust
sensor sensitivity.
Board will not index after
dispensing
No SMEMA signal from
downstream system
Call a trained service technician.
Board will not move to
correct position
Stop pin not receiving air Call a trained service technician.
Part sensor dirty Clean part sensor.
Conveyor rails too close
together
Adjust width between conveyor rails.
Conveyor chain
movement is erratic or
unsteady.
Accumulated debris in chain
Use an airgun or dry, clean cloth to remove
debris from the conveyor chain.
Conveyor chain is loose
Tighten chain by repositioning conveyor motor
(motor weight provides adequate tension).
