For each error message, one or more
possible explanations and suggested
solutions are provided.
1. Signal Processor Not Available
Explanation
There are no internal signal processor PCBs
and/or external signal processors active or
enabled in the system.
Solutions
A. If an STX PCB(s) is installed in the MVS:
1.The MVS may not recognize the
STX PCB. Rescan the MVS using the
Service/Micro/RScn/Auto/i2c_IO
Menu. See Chapter 8, MVS-STX
Service Menu.
2.All channels may be disabled. Display
selected disabled channels again by
turning Enabe on, using the Service/
STX/Enabe Menu. See Chapter 8,
MVS-STX Service Menu.
3.The STX PCB may not be installed
properly. Ensure the PCB is inserted
into the card guides and is mated fully
with the backplane connector.
4.The STX PCB may be malfunctioning.
Replace the STX PCB. Restore the
STX PCB parameters using the
Service/STX/Rtor/STX Menu. See
Chapter 8, MVS-STX Service Menu.
D-1
B. If an external STX(s) is communicating
serially with the MVS:
1.The external STX may not be correctly
wired to COM1. Ensure the external
STX is correctly wired to COM1.
2.COM1 may not be set to Master.
Ensure COM1 is set to Master in the
I/O/Serl/MVS/COM1/Mode Menu.
See Chapter 6, MVS-STX Inputs and
Outputs Menu.
3.The rocker arms on the S1 switch on
the STX PCB, which assign the serial
address, may not be set properly.
Check the rocker arm settings,
referring to Table 2-1 in Chapter 2,
Hardware Installation.
4.The microprocessor PCB in the MVS
may not be installed properly.
Ensure the PCB is inserted into the
card guides and is mated fully with
the backplane.
5.The MVS may not recognize the
external STX(s). Rescan the MVS
using the Service/Micro/RScn/Auto/All
Menu. See Chapter 8, MVS-STX
Service Menu.
6.The MVS microprocessor PCB may be
malfunctioning. Replace the microprocessor
PCB. Restore the microprocessor
PCB parameters using the Service/
STX/Rtor/Micro Menu. See Chapter 8,
MVS-STX Service Menu.
Note
If you have multiple signal processor
PCBs, access Service/STX/Rtor/Micro
from each STX PCB to restore the
parameters from each PCB.
2. Overrange Error
Explanation
Sensor input is causing the counts to go
above 2,097,151 (if +) or to 0 (if -) because
one of the legs of the excitation voltage is not
functioning.
Solutions
A. If using K-M half-bridge sensors, ensure
jumpers JP8 and JP10 on
the STX PCB are on the Half pins.
