e. Check the outlet port for proper function by attaching and removing a source guide tube
equipped with the appropriate bayonet connector. The operation should be smooth and
resistance free. If there is any resistance or ‘crunchy’ feeling noticed during attachment or
removal of the source guide tube or during movement of the outlet port cover, this indicates
excessive amounts of sand or dirt within the outlet port mechanism. The outlet port
mechanism must be removed, cleaned, inspected and lubricated according to the complete
service instructions.
f. Check the locking mechanism and plunger lock to verify attachment and operation. Grasp the
entire mechanism with one hand and attempt to shift the mechanism. Retaining screws that
have been loosened from excessive vibration or improper maintenance will allow the
movement of the locking mechanism during this check. Loose screws must be tightened
according to the annual maintenance requirements prior to use or transport.
g. Use the Model 550 NO GO gauge to check for wear on the remote control cable connector
and the source assembly connector. Replace all components of the “locking system” that fail
any of these tests.
h. Operationally check the automatic securing mechanism and then the function of the entire
system during the first radiographic exposure of the work shift while within a restricted area.
Operation of the radiographic system verifies both the automatic securing mechanism and
entire system operates smoothly and freely. If operation is faulty, remove the gamma-ray
source projector from service and perform the complete annual maintenance.
4.1.4 Misconnect Test
After performing the quarterly or annual maintenance, the complete radiography system must be
tested by the maintenance program administrator or Radiation Safety Officer. A misconnect test
on the gamma-ray source projector including the radioactive source assembly and remote
controls effectively tests the integrity of the entire locking system. This procedure detects long-
term wear (or damage) of the interrelated failsafe system including identification of any excess
wear on the control cable connector, the gamma-ray source projector’s automatic securing
mechanism and sealed source connectors simultaneously.
Note: Component wear occurs to both the control assemblies and the device locking
mechanisms over time, therefore, to ensure acceptable equipment operation, the
misconnect test must be performed on each device lock assembly and control
assembly that will be used for radiographic operations. All remote controls must
be tested using a QSA Global, Inc. manufactured automatic securing mechanism
equipped with a QSA Global, Inc. manufactured source assembly, 550 jumper or a
mock source assembly (A424-14XL for the SENTINEL SENTRY 110 and A424-13XL
for the SENTINEL SENTRY 330) to ensure the effectiveness of the misconnect test.
