7 Troubleshooting
7.1 Overview
If you have difficulty operating your dispensing system, use this section to identify a possible solution to
the problem. If you have difficulties not listed in this section, or the suggested solution does not correct
the problem, contact Asymtek Technical Support.
NOTE There are no user serviceable parts inside the electrical modules. Refer to the Fluidmove
User Guide or Fluidmove Online Help for assistance with the Fluidmove software.
7.2 Safety First
Operation of your dispensing system involves heat, air pressure, electrical power, mechanical devices,
and the use of hazardous materials. Read this manual in its entirety before attempting any system or
component operation. It is essential for all personnel working on or around the dispensing system to fully
understand the hazards, risks, and safety precautions associated with operating the system. When properly
operated and maintained, the dispensing system is safe and reliable. See Section 2 - Safety for additional
information.
WARNING! Allow only qualified personnel to perform system troubleshooting. Observe and
follow the safety instructions in this document and all other related
documentation. Failure to do so may cause serious bodily injury to the user or
damage to the equipment.
WARNING! DO NOT hot swap connections when working with electrical and pneumatic
power supplies. Turn the main circuit break off before disconnecting the external
power plug from the facility.
7.3 Record Keeping
The type of procedure performed should be recorded in maintenance records for the dispensing system.
Dates, part numbers/serial numbers of replaced parts, names of technicians, and other pertinent data
should be recorded.

7.4 Basic System Troubleshooting
7.4.1 System Power
Table 7-1 System Power Troubleshooting
Symptom Possible Cause Recovery Procedures
No power to major
system components
The ON (l) button has not been
pressed.
Press ON (l) on the front panel. The green
button illuminates green as an indicator the
machine is on.
A circuit breaker has been tripped.
The dispensing system incorporates circuit
breakers with a “push to reset” feature rather
than fuses. There are also branch circuit
breakers which could cause the laptop to lose
AC power and/or the 48V servo power supply
to lose power. For detailed troubleshooting of
power related issues, contact Asymtek
Technical Support.
A branch circuit breaker in one of
the conveyor modules has been
tripped.
Main power cable is disconnected.
Check that the main power cable is connected
to an AC source.
Main power circuit breaker turned
OFF.
Turn ON the main power circuit breaker at the
rear of the system. The sub-systems receive
electrical power entirely through the power
manager, accessible from the rear of the
machine. The main circuit breaker switch is the
only mechanism for completely powering down
the system, including power to the laptop.
EMO button has been activated.
1. Turn all EMO buttons clockwise until they
pop out. The EMO buttons at the front and
rear of the system interrupt power to all
power connections except the laptop
computer, light beacon and camera.
2. Press
ON
(
l
) on the front panel.
Interlock circuit is interrupted.
Make sure the dispensing area door 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 dispensing area door
does not completely power down the
dispensing system and does not power off the
laptop.
Ventilation Time Delay (Flux
Applications).
The dispensing system turns on after an
approximate 60-second vent air time delay.
A fuse on the Main PWA may have
blown.
Replace fuse, see 8.16 Replacing Fuses.
System fails to start
Power controls cable disconnected.
Verify the power controls cables are properly
routed and connected from the power
manager to the front panel switches.
Button failure. Contact Asymtek Technical Support.
Safety Interlock fails to
reset
Interlock activated.
Make sure the hood is closed. If the interlock
still fails to reset, contact Asymtek Technical
Support.

7.4.2 Conveyor
Table 7-2 Conveyor Troubleshooting
Symptom
Possible Cause
Recovery
Rails or belt will not move
EMO button has been activated.
1. Turn the EMO button clockwise until it pops
back into position.
2. Press ON (I) on the operator’s console.
X or Y Motor cables are loose. Contact Asymtek Technical Support.
Fuse is blown in conveyor/heater
controller power supply.
Check the fuses by the heater power
connections on the conveyor controller and
replace if necessary, see 8.16 Replacing Fuses.
Conveyor/heater controller
malfunction.
Contact Asymtek Technical Support.
Stop pins, lift tables or
clamps are inoperative
Tooling air pressure is too low.
Adjust tooling air pressure regulator to supply
275 kPa (40 psi).
There is an air leak in a pneumatic
line or component.
Leaking component or line must be located and
repaired or replaced. Contact Asymtek Technical
Support.
The pneumatic device has failed. Contact Asymtek Technical Support.
Solenoid valve is defective.
The solenoid valve must be replaced. Contact
Asymtek Technical Support.
Conveyor may not be properly
configured in Fluidmove.
Contact Asymtek Technical Support.
Conveyor does not
transfer parts from
upstream to downstream
machines
Workpiece or carrier is jammed. Contact Asymtek Technical Support.
SMEMA interface is not functioning
properly.
Contact Asymtek Technical Support.
Incorrect alignment of upstream or
downstream machine.
The machines must be realigned. Contact
Asymtek Technical Support.
Board sensors not
sensing when board is
present
Board sensor is not active. Contact Asymtek Technical Support.
Board sensor is dirty.
Clean board sensors with a soft cloth or with
blown air.
Board sensor is out of adjustment. Contact Asymtek Technical Support.
Board will not index to
correct position
Stop pin is not receiving air. Contact Asymtek Technical Support.
Board sensor is dirty, not active or
out of adjustment.
Clean board sensor.
If no improvement, contact Asymtek Technical
Support.
Gap between conveyor rails is too
narrow
Check conveyor width and readjust as
necessary.
Conveyor does not move
at all (with Fluidmove
position controls)
Conveyor/heater controller has
no power.
Verify that the AC power cable is connected to
the module and to the facility power source.
Branch circuit breaker in 30A
power manager tripped.
Reset circuit breaker.
Conveyor jams or does
not move
Gap between conveyor rails is too
wide.
1. Stop the dispensing program.
2. Realign the workpiece on the conveyor belt.
3. Use the Fluidmove position controls to adjust
the rail gap.
4. Restart the dispensing program.
The carrier is bent.
Stop the dispensing program and remove the
carrier.
Fails to find width Home
The width “home” sensor has
failed.
Contact Asymtek Technical Support.
