Meter does not
stop dispensing.
Meter valve is blocked with debris -
flow bars DO NOT show on the meter
display when the trigger IS NOT actu-
ated.
Flush the valve with mineral spirits at high pressure and
flow. Warning: Do not exceed the maximum working
pressure of the meter (1500 psi - 103 bar). If flushing
does not resolve the problem, the meter should be
replaced.
Trigger or trigger membrane switch is
damaged - flow bars DO show on the
meter display when the trigger IS
NOT actuated.
Replace the trigger and trigger membrane using the
Trigger Repair Kit (246439 N. A., 249883 Australia). See
page 33. Do not use clamps or wire ties to hold trigger
during dispense, doing so voids the warranty.
Dynamic System Pressure (while dis-
pensing) exceeds the recommended
600 psi (4.1 MPa, 41.4 bar).
Reduce system pressure. A lower ratio pump may be
required to reduce pressure and maintain sufficient flow.
A hydraulic quick disconnect was
used to connect the meter to the dis-
pense hose, allowing debris to block
meter.
Do not use quick disconnects with Matrix product. Use
of quick disconnects voids the warranty.
Displayed dis-
pensed amount is
not accurate.
Meter is not programmed for the cor-
rect fluid type.
Verify meter programming.
Meter gears are worn. Meter requires calibration due to wear. See page 19.
Meter will not take
work orders.
Battery has low charge or is dead. Recharge battery.
Battery inserted too soon. Wait 30 seconds and reinstall fully charged battery.
Meter may not be programmed. Reprogram meter.
Battery may have been pulled during
programming.
Reprogram meter.
Two meters may be programmed as
the same meter.
Ensure each meter is programmed individually.
Meter work order list is full. Normal operation. Meter will hold up to 5 work orders.
Meter has intermit-
tent or no RF com-
munication.
Meter is outside RF communication
range of transceiver.
Reposition transceiver or add a transceiver.
Two meters may be programmed as
the same meter.
Ensure each meter is programmed individually.
PC or transceiver is off. Turn PC on, open Matrix application, and check power
on transceiver.
Meter will not pro-
gram.
Incorrect COM port selected for
transceiver connection.
Change to correct COM port at the PC in Matrix trans-
ceiver configuration screen.
Transceiver is not powered up. Power up transceiver, wait 30 seconds or until red lights
go blank and green light remains on alone.
Transceiver dip switches are not set
for the communication cable being
used.
See transceiver manual 309498 to set dip switches.
Matrix program is not in programming
mode.
Place PC in programming mode. See Programming the
Meter, page 4.
The five-minute programming ses-
sion has expired.
Place PC in programming mode. See Programming the
Meter, page 4.
Network and transceiver settings on
the meter are not correctly set.
Make appropriate settings. See Programming the Meter,
page 4.
