Routine Checks
This section describes the routine checks required to ensure the
correct operation of the SAM12. Most mechanical and
electronic failures, if they occur, will become apparent during
normal operation and do not require checking. Therefore, they
are not included in this section.
Mechanical Checks
Once a month, or during source checks, check the operation of
the door lock, if the option is fitted. To do this, perform a
measurement with a source known to give alarms. When the
alarm occurs, check the door is locked and remains locked,
after the Residual Contamination Check if the option is
selected. Enter a valid password in the normal way (see
Gaining Access to the Administration Mode (page 5-3) ) and
check the door unlocks. For the two door SAM12 with door
locks, opening one door will lock the other.
Alternatively the locks can be exercised individually (see
Vault
(page 5-18) for more information).
During calibration, or more frequently if required, check any
mechanical structure on which the SAM12 may be mounted.
Since the SAM12 with especially with 2" of lead shielding is
very heavy, any mounting arrangement should be inspected for
signs of deterioration, instability or any other factor which may
affect safety of operation or maintenance. If any such defect is
suspected, the SAM12 should be withdrawn from service and
safely removed using a suitable forklift and the integral fork
lifting facilities provided. The mounting should be repaired
and made safe before replacing the SAM12.
See
Door Lubrication (page 11-10) for details regarding
lubrication of the knuckles of the door hinge.
Any other mechanical faults should, if they occur, become
apparent during normal monitoring operation.
