7 FAULT RESOLUTION
7.1 THERE IS NO LINK TO THE SYSTEM
The equipment will indicate a fault in the link to the system when a short-circuit o
disconnection in the transmission path is detected.
Check that the MPS 8Z does not link, it is the only bus that can not connect. If there are
more devices on the bus with this problem, start by checking the closest to where the bus (NEO)
begins.
Check that the equipment to which the ACSI bus (NEO Controller) is connected works
properly.
Check that the last equipment of the bus has the "Terminator Bus" option active according
to section 3.2.8.
Connect the peripheral power supply provided with the computer in case the MPS 8Z is
directly supplied from the ACSI bus.
Check that the connection between the equipment and the system has been carried out
properly according to section 5.2. To debug the fault, disconnect both ends of both bus cables
connected between the system and the equipment and measure between their terminals with a
multimeter on the scale k . If the result result is 0, the line is in short-circuit and must be checked
Ω
or replaced. If the result is 1, it means that it is correct.
Do a RESET (the equipment will have to be reconfigured). To do so, simultaneously press
the "CANCEL", "EVENTS" and "MEMORY" keys for 5 seconds. The equipment will restart.
Configure the address of the equipment according to 5.2.
If none of the above works, remove the equipment from the bus and contact the
support/repair service. If there are more devices connected to the bus, connect the input and
output bus ACSI lines of the equipment to allow the rest of the system to keep working normally.
7.2 CONDITION INDICATORS BLINK SIMULTANEOUSLY
The system will indicate an ACSI bus address fault when there are two devices with the
same address.
Check that the bus address is correct; to do so, follow the steps in 5.2 .
Do a RESET (the equipment will have to be reconfigured). To do so, simultaneously press
the "CANCEL", "EVENTS" and "MEMORY" keys for 5 seconds. The equipment will restart.
Configure the address of the equipment according to 5.2.
If none of the above works, remove the equipment from the bus and contact the
support/repair service. If there are more devices connected to the bus, connect the input and
output bus ACSI lines of the equipment to allow the rest of the system to keep working normally.
7.3 NO INDICATOR LIGHTS UP
If this is the case, there is probably a problem with the power supply of the equipment.
If the equipment is supplied from the ACSI bus, disconnect the equipment from the bus and
connect the peripheral power supply provided to the equipment. The equipment must do the
indicators verification test.
If the problem persists or it is connected to the peripheral power supply and the bus
simultaneously, follow the steps in section 7.1.
7.4 THE VOICE WARNING SOUNDS LOUD/LOW
If the problem is common to all the equipments connected to the bus, check the
configuration of the equipment to which the bus (NEO) is connected.
In case it is a MPS 8Z in particular, check the volume configured according to section 5.3.6.
