Monthly - Loma X5c Operating Instructions Manual

Inspection and Cleaning

Monthly

1. Check that the two internal cabinet cooling fans, located in the lower section of the
cabinet either side of the X-ray tank, are working correctly. They should be running all
the time that mains power is connected and the system keyswitch is in the XRAYS ON
position.
Do not attempt to check operation of fans with X-rays on and interlocks
overridden.
Do not operate the system if any fans are not running. In this unlikely event
please contact your local Loma Service centre for advice.
If the system has not been used for a period of one month or more then it is
critical that the X-ray set is re-seasoned. Failure to do so could cause the X-
ray set to be stressed and this may result in premature failure. It may also
invalidate the system warranty. If in doubt, please contact your local Loma
Service Centre or Loma Systems directly.
2. Check inside the system cabinet for X-Ray oil cooling system leaks at hose clamps.
3. Check inside the system cabinet for water ingress from over-aggressive high-pressure
water cleaning.
4. Check that the belt and all rollers are clean and free from debris and greasy
elements.
5. Check that all rollers are square across the conveyor and can rotate freely.
6. With the belt in a slack condition and centralised along the length of the conveyor,
adjust the tensioning evenly until there is no slippage when the belt is under load.

7. (3 Monthly) Check the oil colour, which starts clear, but will progressively change due
to the action of the ionising radiation. It must not be allowed to get darker than pale
straw colour. If the oil is darker then this arrange for it to be changed with your local
Loma Service Centre.
8. (3 Monthly) With the system isolated from the electrical supply check that the oil level
in the x-ray tank is approximately 15 mm below the filler plug. Any dip stick used must
be cleaned with suitable paper, fabric lint could cause contamination. The filler plug
is located on the top of the x-ray tank.
This oil level should not require adjustment unless a leak in the system is
present. In addition it should be noted that the oil is of an insulating type
specific for x-rays and must not contain any moisture or air bubbles. Top up
oil should only be obtained from Loma Systems as standard oil direct from
the manufacturer requires additional processing to meet the specification
required.
