STX Signal Transmitter Installation and Operation ... - Kistler-Morse

Chapter 8. MVS-STX Service Menu
The Enter Key moves the cursor to the left of
each parameter. The Function Keys also
move the cursor to the left of the parameters:
F1 Key for the MVS channel number, F2 Key
for the type, and F3 Key for the channel
state. Then the Arrow Keys scroll to the
desired value.
Note
1. You must use the Man Menu to set
up and gain access to math
channels. See Chapter 9, MVS-STX
Math Channels.
2. If you select math channel (MA) for
type, the display indicates
Adr> NA and Ch>?, because a
math channel is not associated with
a signal processor PCB.
RsRAM (reset RAM
memory)
This function resets the non-volatile RAM
(NVRAM) on the Microprocessor PCB. This
resets all parameters for all channels in the
system to the factory-set defaults (i.e.,
calibration, setpoint, display parameters,
etc.). The MVS requires you to enter the K-M
Service Code (9010) to access this function,
and requests verification before it resets
the NVRAM.
Stdr (standardize STX PCB)
This function provides the ability to standardize
an internal STX PCB. Standardizing is
initially performed at K-M. If you replace an
STX PCB, using the Stdr Menu allows the
new PCB to function identically to the
replaced PCB, without recalibrating.
Consult with K-M on the use of Stdr if you
replace an STX PCB.
Serl (serial monitor)
Serl monitors the COM1 serial port when the
MVS is the Master device. Serl has two
submenus: Test and View.
Test
Test allows you to troubleshoot serial connections
between the MVS and slave serial
devices. When using Test the MVS outputs
the following serial command repeatedly:
00#ssr
To troubleshoot, follow this procedure:
1. Disconnect all but one of the slave serial
devices. Set the remaining serial device’s
address to 0.
2. Select Test in the Serl Menu. The MVS
displays TEST TRANSMISSION IN
PROGRESS XXX, with ‘XXX’ replaced by
the number of test transmissions sent.
3. Check the LED on the serial device — a
flashing LED indicates it is responding to
the serial command.
4. To exit the Test, press the Esc Key.
5. Repeat with the remaining slave serial
devices as needed.
View
View allows you to view the serial commands
in the transmit buffer and receive buffer for
each channel. The display top line shows the
channel number and the command in the
transmit (TX) buffer. The bottom line shows
the information in the receive (RX) buffer,
without the initial ‘A.’ Pressing the Arrow
Keys scrolls to other channels. Pressing the
F3 Key scrolls through the string in the
receive buffer if the entire string does not fit
on the display.
Ramtst (RAM test)
This function performs an internal, nondestructive
test on the non-volatile RAM
(NVRAM) on the Microprocessor PCB. This
test does not reset any parameters. Upon
test completion, the display should say Micro
NVRAM Test Passed! If it does not, contact
K-M. When the test is complete, press the
Esc Key to return to the Micro Menu.
Access
This menu allows you to:
• set a user-defined access code
• input the K-M Mfg Code, needed to
perform certain troubleshooting functions.
Access has two submenus: User and KM.
User
The MVS arrives from the factory without a
user-defined access code in place, allowing
the user to access any function (other than
those requiring K-M Mfg Code or K-M Service
Code). The User function allows you to set up
a code to limit access to changing any
parameter (i.e., display parameters, setpoint
parameters, calibration parameters, etc.).
