Troubleshooting

ADM not dis-
playing when
system turned
on
Main power circuit
breaker off or power
cord unplugged.
Turn main circuit breaker on or plug in power cord.
Cable on ADM
unplugged.
Reconnect ADM cable.
Connector on MZLP
board not plugged in.
ADM cable should be plugged into J6 of the MZLP board.
Bad 24VDC power sup-
ply.
Check output on power supply should measure 24VDC, if no voltage
reading replace power supply.
ADM not functioning
properly.
Replace ADM.
Main breaker
tripping
Wrong setting in ADM
breaker setup.
Wrong breaker setting on ADM in the breaker setting in the setup
screen.
Internal short to ground
in system.
Unplug or disconnect power and measure between each leg of the
power to ground. There should be an open resistance reading.
Too small of a circuit
breaker in main power
panel.
Consult qualified electrician for proper size circuit breaker.
Slow start-up
time or system
takes longer
than 10 min-
utes to startup
Wrong setting in ADM
breaker setup.
Wrong breaker setting on ADM in the breaker setting in the setup
screen.
Low incoming voltage. Incoming voltage should be 200-240VAC for a 230 volt unit and 380-
400 VAC for a 400 volt unit.
Melter heater rod and
gun manifold.
Measure and check heater rods in melter or manifold. Manifold resis-
tance 130-140 ohms.
Heated hose. Measure heater wires in hose, pins C and D. See repair section for
each hose resistance.
Insufficient power sup-
plied to system.
Depending on hose
and gun combinations,
along with minimal sup-
ply power, startup time
will vary.
Connect system to a power supply capable of maximum power per
system specification. All changes must be performed by a qualified
electrician. See Electrical Schematics on page 76 for details about
connecting to a different power supply.
No adhesive or
little adhesive
being dis-
pensed
Incorrect RTD setting in
system.
1. Verify melter, hose, and manifold temperatures are all with in the
same range of the room ambient.
2. If the manifold temperature is either much higher or much lower than
the melter temperature then the RTD setting is not correct for the
RTD being used. Select correct RTD setting in the setup screen sys-
tem 2 before beginning.
NOTE: Failure to have the correct RTD value will cause the manifold
and gun to either under-heat or over-heat. Setting for RTD in the ADM
screens is higher than actual RTD value. Consult manufacturer for
actual RTD value.
