Troubleshooting Guide
When a fault is displayed in the detector’s display panel, this troubleshooting guide will
help you identify what problem has occurred and how to correct it. If the APEX detects a
fault, the red LED indicator on the control panel turns on and stays lighted. In addition,
the display panel will show a fault message. These are described in more detail below.
Search-Head Faults
Problem Solution
The search-head cable
connection is broken.
Examine the cable connections at both ends to make
sure all wires are connected correctly.
The search-head balance
is out of range.
This sometimes occurs when the APEX is moved. Please
have the APEX reinstalled by a Thermo Fisher Scientific
technician.
Other search-head
problems.
Contact Thermo Fisher Scientific—as described in the
“Contacting Thermo Fisher Scientific” section at the end
of the manual.
Battery Low Fault
Problem Solution
The battery powering the
memory is becoming
discharged when the main AC
power to the detector is off.
Replace the battery and/or control panel. However,
if the main AC power is not turned off, operation of
the detector will not be affected.
Product Memory Fault
This fault indicates the product memory has been lost or damaged.
Problem Solution
Low battery could cause
memory to be lost when the
unit is not powered.
Check the battery.
Detector has been subjected
to high static discharges or
lightning.
Erase the memory.
Speed-Encoder Fault
This type of fault only occurs in conveyor applications using an external speed encoder.
Problem Solution
The detector is not getting a
signal or a properly pulsed
signal from the external
speed encoder. Retest APEX using a test sample and with the belt
running. This may clear the fault. If not, check the
functioning of the external speed encoder.
