7.6 CoolCUBE
II
: Low Coolant (Air in the Hoses)
CAUTION!
!
If more than two inches (50.8 mm) of the coolant line is
filled with air, the pump will stop working and may be
damaged. If flow stops while the pump is on, turn off the
CoolCUBE
II
and add coolant.
1. Unscrew the reservoir cap (on top of the CoolCUBE
II
) and make sure that the
coolant reservoir contains coolant. If additional coolant is required, fill with a 50:50
mixture of water and ethylene glycol.
2. Screw the reservoir cap back in.
3. Make sure the power switch is turned off before plugging the circulator in.
4. Plug the circulator into a 100-240 V
AC
, 47-63 Hz power source.
5. Turn the circulator on. Make sure there are no leaks or air bubbles in the hoses.
NOTE:
Small air bubbles (about the size of bubbles in soda) are
common in the CoolCUBE
II
especially at start up and do not
prevent proper operation.
• If there are no problems, continue to step 6.
• If there are leaks or air bubbles, turn the circulator off and correct the
problem(s) by securing the hoses or adding more coolant to the reservoir. Turn
the circulator back on. Recheck and if there are no problems, continue to step
6.
6. Turn the camera on.
7. Start the application software.
7.7 Cooling Troubleshooting
This section provides information about troubleshooting cooling-related issues.
7.7.1 Temperature Lock Cannot be Achieved or Maintained
Possible causes may include:
• Ambient temperature greater than +20°C. If it is greater than +20°C, you will
need to cool the camera environment or raise the set temperature.
• Airflow through the camera and/or circulator is obstructed. The camera needs
to have approximately two (2) inches (50 mm) clearance around the vented
covers. If there is an enclosure involved, the enclosure needs to have
unrestricted flow to an open environment. The camera vents its heat out the
vents near the nose. The air intake is near the rear of the camera.
• A hose is kinked. Unkink the hose.
• Coolant level is low. Add coolant. Refer to Section 7.6, CoolCUBE
II
: Low
Coolant (Air in the Hoses) , on page 81.
• There may be air in the hoses. Refer to Section 7.6, CoolCUBE
II
: Low Coolant
(Air in the Hoses) , on page 81.
