System Checks
Initial Instrument Check
Once the Model 4525 has been properly installed, it should be ready for normal
operation upon checkout. The following procedures will take you through the
initial checkout of the instrument and its operation.
Note:
Installation instructions with drawings and diagrams can be found in the
Model 4525 Installation Manual.
1. Ensure that detectors, vehicle sensors, and any optional accessories are
properly connected to the main electronics (i.e. printer, computer, strobes,
horns, etc).
2. Confirm that the main electronics are connected to 110 Vac (220 Vac if
applicable).
3. Flip the power switch on the connector plate inside the master detector
panel to the
ON
position. When this is done, all of the relays (that control
the external horns or lights) will be activated for approximately five seconds.
The relays then turn off, with the exception of the
POWER OK
light that stays
on, and the
CHECKING
light that will flash for 30 seconds.
4. At the end of 30 seconds, confirm that there are no
INSTRUMENT FAILURE
indications on the remote display or computer screen. The software, if used,
should indicate the background level of radiation, and the absence of any
vehicle within the system. The remote display, if used, should indicate
POWER OK
status only. Proceed with the operational check.
Operational Check
The operational check is an important assurance that the vehicle detection
sensors and radiation detectors are working correctly. It is suggested that the
operational check be performed on a weekly basis. This test, when coupled with
the automatic system diagnostics, will ensure proper system operation.
