2-4. CONFIGURATION WORKSHEET.
Since Level 2 Configuration can become some-
what complicated, it is important to determine the
desired changes before performing Level 2 Configura-
tion. To use the configuration worksheet (figure 2-8),
proceed as follows:
A.
Make photocopies of the worksheet.
B.
Choose the “standard” keyboard configura-
tion (Level 1 Configuration) which provides most of
the warning system requirements. Determine the
changes required as follows:
1.
See figure 2-6. Determine the pre-
programmed pattern number (if any) for the switch.
NOTE
Pre-programmed patterns are executed by
the Vision’s seven pods.
2.
If the SignalMaster is installed,
determine the SignalMaster pattern (if any) for the
switch. See figure 2-5.
3.
Determine the auxiliary relay
output(s) to be activated (if any) for the switch.
4.
Determine the switch operation (push-
on/push-off, momentary, or eight-second timed) for
the switch.
5.
Record the desired configuration
changes on the worksheet.
C.
Repeat step 2-4.B. for each switch to be
reconfigured.
NOTE
Use Keyboard Configuration 7 (refer to Sec-
tion I) if it is necessary to design a com-
pletely new keyboard configuration.
D.
Use the worksheet as a guide and configure
the warning system as required.
2-5. TEST AFTER CONFIGURATION.
After configuration is complete, test ALL warn-
ing system functions to ensure that all functions and
controlled devices (if any) operate as intended. Test
all vehicle functions, including vehicle light systems,
to ensure proper operation.
WARNING
Peoples’ lives depend on the safe use of the
Vision warning system. After testing is com-
plete, ensure that all operating personnel
fully understand how to operate the Vision
warning system.
2-6. CONFIGURATION MODE DISABLE/ENABLE.
A.
Disable.
After the Vision warning system is config-
ured and fully tested, it may be desirable to disable
the configuration mode and prevent reconfiguration
by unauthorized individuals. To disable the configu-
ration mode, proceed as follows:
1.
Loosen the two hexagon head screws
on the underside of the Interface/Relay Unit, near
the front edge of the unit. Slide the chassis out of the
case.
2.
See figure 2-9. Cut JU1 on the Inter-
face/Relay Unit circuit board to disable the configura-
tion mode.
3.
Replace the case and secure with the
previously loosened hexagon head screws.
B.
Enable.
If the warning system was previously
installed, configured, and the configuration mode was
disabled, enable the configuration mode as follows:
1.
Loosen the two hexagon head screws
on the underside of the Interface/Relay Unit, near
the front edge of the unit. Slide the chassis out of the
case.
2.
See figure 2-9. Place a jumper across
JU1 and perform the configuration as required. If
desired, remove the jumper across JU1 to disable the
configuration mode.
3.
Replace the case and secure with the
previously loosened hexagon head screws.
2-7. CONFIGURATION QUICK REFERENCE.
A.
Level 1 Configuration.
1.
Power-up the system and wait for the
self-test to complete. The Reset/Save LED changes
from flashing to steady illumination and a beep
sounds indicating the system is ready for use.
