To ensure constantly safe performance of the collimator and its compliance with appli-
cable regulations, a maintenance program is indispensable.
It is the Owner's responsibility to supply or arrange for this service
Cleaning recommendations
If the collimator is not protected by an overall cover, the covering must be cleaned as
prescribed by the sanitary regulations followed by the operator.
• Disconnect supply
• Use non abrasive cleaning products.
Care must be taken to prevent liquid from entering the collimator.
N.B. the collima-
tor cover is not watertight.
Do not re-apply power if inflammable liquids have leaked into the collimator.
See the following Maintenance Instructions.
Recommended maintenance programme:
Ralco suggests a yearly servicing programme. However shorter intervals are advisable
when the collimator is subject to heavy workloads.
• Re-calibration of the collimator will be necessary whenever the x-ray tube is
changed.
Calibration procedures must be performed as described in this manual.
• Check that the screws which serve to secure the collimator to the flange/tube
adapter are correctly tightened.
• Remove the covers and panels from collimator. Inspect the moving parts for signs
of wear or damage.
• Check the electric system and substitute parts that show wear.
• Check the Lexan panel and substitute if necessary.
• Clean the collimator with a soft cloth paying particular attention to the Lexan win-
dow.
Do not
use abrasive or inflammable cleaning products.
• Sparingly lubricate the moving parts using graphite oil.
• Wipe away all excess oil and remount the cover.
