Testing Electronic Unit
This test is only a test of the electronic unit for troubleshooting
purposes, and does not serve as a Verify or Certify test of the
complete system.
Use the following steps to test the electronic unit:
1. Be sure the environment is safe before removing the lid from
the housing.
2. If possible to access the sensing element with the material
below the sensor, or remove the IntelliPoint from the vessel,
use your finger to touch TP1 (Shown in Figure 2-4) while
holding any bare metal portion of the instrument housing
with the other hand. The system should go to its high level
state.
3. Again with no material touching the sensing element, touch
the tip of the sensing element with your finger, while holding
any bare metal portion of the instrument housing with the
other hand. The system should go to its high level state.
4. If the IntelliPoint changes to the high level state while
touching test point TP 1, but not when touching the tip of
the sensor, in most cases, the interconnecting cable is faulty.
See Section 4.6: Testing Integral Cable, or Section 4.7
Testing Remote Cable.
5. If The IntelliPoint is stuck in one state:
A. Remove power.
B. Disconnect coax cable that joins sensing element to
electronic unit.
C. Apply power.
D. Repeat steps 3 and 4.
E. If The IntelliPoint changes state with sensing element
disconnected, in most cases, sensing element is faulty.
See Section 4.5: Testing Sensing Element.
6. If there was no action in any of steps 2, 3, or 4:
A. Remove and then reapply power.
B. Press ReCal Button (
Shown in Figure 2-4
).
C. Observe that green LED flashes for about 60 seconds.
D. Green LED should be lit after 60 seconds.
E. Touch test point (
Shown in Figure 2-4
) with your
finger.
F. Alarm & Loop Current should change state. If so, circuit
board is working properly.
G. Reinstall instrument and press ReCal Button.
7. If The IntelliPoint fails all of above tests, in most cases
instrument is faulty. Use a replacement Input/Output
Module (IOM) or circuit board to determine fault.
