Appendix 3
Levers 1 & 2 Function
Notes
Both up
Normal
cooling
Both fans run continuously increasing in speed as the
temperature inside the frame goes up.
1 down, 2 up
Quiet mode
For use with a lightly loaded frame for low ambient
temperature. When the frame temperature is below
approximately 45°C the panel fan is switched off and the PSU
fan runs at minimum speed. If the frame temperature goes
above 45°C it reverts to normal cooling and goes back to quiet
mode when frame temperature falls below 42°C.
1 up, 2 down
Max cooling
mode
In Maximum cooling mode both fans never run below near
maximum speed. Fan speed increases to maximum at high
frame temperature. This mode is ideal for equipment bays
where noise is not a concern.
Both down
Reserved
for future
use
Operates as normal mode with current software.
Note:
Quiet mode is dependent on PSUs and PSU fans not being in an alarm state.
For the 2SE CoolFlow, only one of the fans is essential in normal operation. If
one of the fans should fail, the closed frame can still operate indefinitely with an
ambient temperature of 40°C.
Warning:
Although it is possible to operate the frame with the front panel open, the frame
may not meet electromagnetic compatibility (EMC) requirements in this
condition.
Terminating the RS422 Statesman chain
The RS422 communication chain was used by older, pre-Ethernet-enabled frames and is no
longer supported by Crystal Vision. A frame should be terminated when it is the last device in a
chain or a when the only device. It is unterminated for all other applications including when
frames are used with a Statesman Hub. To change the RS422 communications termination
access the RS422 term/unterm switch at the top of the front control panel by opening the panel
and lifting it upwards.
To terminate the RS422 link move the switch to the left, to unterminate it move it to the right.
Frame Address
The frame address (which only relates to older, pre-Ethernet-enabled frames with active panels)
is set to give a frame a unique address when used in serial 422 connected systems
. In
Ethernet-enabled frames the frame address switch must be set to zero.

Frame Address
Normally
zero
This is usually the address of the frame from 0 to 15.
