11. TROUBLE SHOOTING

11.1 General problems

PROBLEM WHAT & WHERE SUGGESTION

Piezo Over Heating, slow down dispense parameters.

Adjust longer dwell time (wait for temperature to drop

before starting again)

Intermittent, RTD connection may have a problem

Check connection of Sensor cable

loosen screws and re-align manifold

Replacing Tappet seal

Replace Tappet

Re-calibrate

Replace Tappet

Air cool is kicking On (normal)

ERROR message displayed (see Error problem)

REBOOTING

Controller keeps on

rebooting

Disconnect actuator cable, if controller reboot and stay

on the Piezo is shorted (Please Return valve to Techno

for evaluation)

Check connection of actuator cable

Manual dispensing must be in Dot Mode

Line Mode required external trigger, check external

triggering device

Nozzle maybe clogged

Syringe pressure must be On or connected

Re-calibrate

System must be On since the valve is in a Normally

Open without power

Make sure the Valve Close icon in the main menu is in

the Close Mode

Tighten up nozzle nut assembly and re-calibrate

Refer to Leakage section

FREEZES

Touch screen froze

If system froze up please reset using the On/Off switch

on the back of the controller

Valve not running

Valve running but nothing

come out

NOT

DISPENSING

W/OUT

ACTIVATION

Drops or stream of material

coming out from the nozzle

11.2 General functions

FUNCTIONS WHAT & WHY SUGGESTION

Minimum setting is 80 µs

Maximum setting is 1999 µs

Depend on viscosity start at about 300 µs

Rise time can also affect the accumulation or satelliting

Low viscosity material open time can be short 1-300 µs

Med viscosity material open time can be 200-1000 µs

High viscosity material open time can be 500-2500 µs

Smaller the shot smaller the open time

Bigger the shot larger the open time

minimize the open time to keep the shot as clean as possible

Minimum setting is 80 µs (smaller the value stronger the

punch/jetting)

Maximum setting is 1999 µs (larger the value slower the

punch/jetting)

Higher viscosity required stronger punch/jetting setting

Fall time can also affect the accumulation or satelliting

Slow down the fall time to reduce satelliting

Increase the fall to reduce accumulation

More important in the Line Mode

Important in Dot Mode if there are multiple pulses in one dot

(number of pulse in a certain time)

Single pulse/dot jetting delay time is not important since to

robot movement will take a longer time

The shorter the delay the closer the dots as it try to connect

the dots to form a line

The longer the delay the further the dots as it try to connect

the dots to form a line (it may not form solid line)

Higher lift for stronger punch/jet

The vale is more stable with lift higher than 40%

Higher lift will produce more volume (depending on open

time as well)

Lower lift will produce less volume (depending on open time

as well)

Higher lift and shorter fall time may be necessary for

dispense high viscosity material as well as stringy material

(Heater may help in bringing down the lift and fall time)

Dot Mode this can be set from 1 to 9999999 pulses

Line Mode it is not adjustable (default to pre set value)

One dot can be an accumulation of multiple pulses (e.g. one

dot can be 1 pulse or 20 pulses)

Multiple pulses can be use to increase the size of the dot or

use a larger diameter nozzle

Help stablize a process

Help lower the viscosity of a material for better flow

Help to reduce the stringiness of a material for better jetting

Consult w/ the material Mfg to prevent over heating of

material, we are not responsible for harden material in the

manifold and nozzle

LIFT

Percentage tappet lift

from fully closed to open

PULSE

A number of shots

HEATER

Heater on the manifold

OPEN

Time to allow material

to fill the cavity and

jetting out

FALL

Time to jet out the fluid

DELAY

Time between pulses

Time to lift the tappet

from fully closed to open
