Note: When adding Option board for 5
digital inputs, associated screw terminal in
the rear terminal block must be installed.
(See information on page 1 for ordering a
Screw Kit.)
To Change the Power Supply or
Microcontroller (CPU) Board
10. For the Microcontroller Board, disconnect the 5-pin
female connector that wires it to the Display
Assembly. Reattach the connector to the new
board. You can only orient the connector one way.
For the Power Supply Board, disconnect the 5-pin
female connector that wires it to the Display
Assembly. Reattach the connector to the new
board. You can only orient the connector one way.
To Change the Display Assembly
11. Disconnect the 5-pin female connector that wires
the Microcontroller Board to the Display Assembly.
Disconnect the 5-pin female connector that wires
the Power Supply Board to the Display Assembly.
12. Attach the new Display Assembly to the boards at
the appropriate connectors.
To Change the EPROM
13. The EPROM is located on the Microcontroller
Circuit board (Figure 2). It has a white label that
list the part number and software revision level.
Use an I.C. Extractor to carefully remove the
EPROM. If you do not have an I.C. extractor,
gently use a small flat blade screwdriver to pry up
the EPROM. DO Not bend the EPROM legs.
14. Carefully insert the new EPROM. To position
correctly, match the notched end of the EPROM to
the markings on the board. The notched end will
face towards the display. Make sure all pins are in
the socket.
To Reassemble the Unit
15. (See Figure 2) Align the connector pins on the
Option Board with the connector sockets on the
Microcontroller and Power Supply boards.
Squeeze them together, making certain all three
are properly seated against one another. Check
along the side edges for gaps. Make sure the
conector is properly aligned. Also, check that the
cable assemblies are not pinched.
16. (See Figure 2) Align the board assembly with the
front face assembly, with the Option board at the
bottom (see Figure 1). Reinstall the retention
clips. Align the boards into the slots of the front
face assembly and the clips will snap into place.
17. When you are ready to reassemble the unit, align
the boards in the chassis with the case's top and
bottom grooves. Press firmly to slide the chassis
into the case. If you have difficulty, check that you
have properly oriented the chassis, and there are
no screws interfering with the case.
18. Carefully insert and align screws. Tighten them
until the bezel is seated firmly against the gasket.
DO NOT OVERTIGHTEN.
19. If may be necessary to re-configure the software
features of your controller or station. Please refer
to your User’s Manual.
20. To maintain NEMA 4X Rating, you may need new
mounting gaskets, order part #535-662. Refer to
your user’s manual.
8. Replace tie wraps for the Retention Plate and for
Output Module 4 with new ones.
Failure to use these devices may result in a
loosening of the module and eventual
failure. If you ordered a module separately,
it should have come with a tie wrap. An
extra set of tie wraps is available by order-
ing Part #535-665.
Note: For greatest accuracy, milliamp
modules added for retransmission must be
calibrated per instructions in Operator's
Manual.
To Change the Option Board
9. (See Photos 3 and 4) Replace the existing Option
board with the NEW one.
CAUTION
Do not scratch the boards or bend the pins of the
connectors.
CAUTION
Static discharge will cause damage to equip-
ment. Always ground yourself with a wrist
grounding strap when handling electronics
to prevent static discharge.
