1) Using a 3mm Allen key, remove
the 8 screws that secure the
instrument cover.
2) Slowly pull back the red cover
until the keyboard connector
can be seen. Disconnect the
keyboard ribbon, and then
remove the cover.

4 Adjust the LED intensity
There are two methods available for adjusting the intensity of the LED:
• Adjusting the LED with a Modbus connection (preferred)
• Adjusting the LED without a Modbus connection (for use if a Modbus
connection is not possible)
4.1 Adjusting the LED with a Modbus Connection
1) Connect a cable terminal to the
4500 MkIII Connector C.
2) Connect a Modbus master to the
RS485 port (green, yellow and
black wires).
3) Apply 24 V dc power to the red
and blue wires of Connector A.
4) Observe Modbus registers 121,
122 and 124. These indicate the
intensity of the LED signals on
the reference detector.
5) Adjust potentiometer PR1 until
Register 124 has a maximum
value not exceeding 56000.
6) Adjust potentiometer PR2 until
Registers 121 and 122 have a
maximum value, with neither
value exceeding 56000.
7) Disconnect 24 V dc power.
8) Disconnect the Modbus cable.
9) Go to Section 5 below.

ensuring it is not offset by one pin.
DO NOT FASTEN THE COVER SCREWS AT THIS POINT.
3) Apply 24 V dc power to the red
and blue wires of Connector A.
4) Using the keyboard, use the
menu to display parameter 124.
5) VERY CAREFULLY remove the
red instrument cover, taking
care not to short-circuit any
components inside the Model
4500 MkIII.
6) Adjust potentiometer PR1 until
Register 124 has a maximum
value not exceeding 56000.
7) Remove 24 V dc power and
replace the instrument cover &
connector as before.
8) Apply 24 V dc power to the red
and blue wires of Connector A.
9) Using the keyboard, use the
menu to display parameter 122.
10) VERY CAREFULLY remove the
red instrument cover, taking
care not to short-circuit any
components inside the Model
4500 MkIII
11) Adjust potentiometer PR2 until
Registers 121 and 122 have a
maximum value, with neither
value exceeding 56000.
12) Remove 24 V dc power.
