I-E96-314A
®
FCS fails to start and
there are no
configuration errors.
(continued)
Improper installation
Verify proper installation of FCS module and related
hardware.
1. Check the Slave expander Bus dipshunt. All the dipshunt
pins should be shorted.
2. Check the slave expander bus address setting on SW1 of
the FCS. SW1 should be the same value as S1 of Function
Code 145.
3. Reinsert the module in the MMU.
4. Check the Termination Unit cable. The cable should
connect the FCS (MMU slot) to the TU.
5. Verify the correct dipshunt configuration on the
Termination Unit.
6. Verify the magnetic pickup is connected to the correct
terminals on the TU.
7. Check the magnetic pickup installation.
Magnetic pickup
failure
Check the input signal from the magnetic pickup.
1. Connect an oscilloscope to the input terminals on the
termination unit. Verify there is a signal from the magnetic
pickup.
2. If there is no signal from the magnetic pickup, check the
continuity of the cables connecting the pickup to the
termination unit.
3. Replace any open cable or cables having an unusually
high impedance.
4. Replace the magnetic pickup if there is no input signal
and the cable continuity checks good.
FCS fails to start and
the related hardware
installation is correct
with no configuration
errors.
FCS module failure
Replace the Frequency Counter Slave Module.
The replacement FCS
fails to start and all
other areas check
good.
