Low Voltage Cable Removal
(Refer to Figure 14)
1. Disconnect low voltage cable [2] from rear of power
supply. For A10406-XX power supply, disconnect
circular connector from receptacle on rear of power
supply. For LECU5004-XX power supply, disconnect
wires from connector J3 at rear of MicroPak.
2. Loosen retaining ring [5] (see Figure 10) and remove
applicator from robot wrist.
3. Using 3/16" Allen wrench, remove set screw [10].
4. Remove the low voltage cable [2] by pulling through
the robot arm and mounting plate.
5. To reinstall, insert power supply end of cable [2]
through mounting plate [3], pull through robot arm
and connect to junction box or power supply. For
connections to power supply, plug connector into re-
ceptacle (A10406-XX power supply) or connect wires
as shown in Figure 4 (LECU5004-XX power supply).
6. Align the timing mark of the plug on the appli-cator
end of the cable [2] with the mark on the mounting
plate [3] and tighten set screw [10].
FLUID REGULATOR
(When Equipped - See Figure 15)
1. Remove all pressures, both air and fluid from
the line leading to the spray gun.
2. Purge all fluid from the gun prior to performing
any service.
3. Remove one end of the tubing [39] from the fitting
[12]. Remove the six (6) screws [11].
4. Remove diaphragm assembly [10] and in-
spect it for wear or damage. Pay particular attention
to the air side, since it can be damaged by solvent
contact. Replace if necessary.
> Once regulator bonnet [10] is re-moved,
diaphragm [2] will be loose and may fall
out.

5. Use a 3/16" Allen wrench to unscrew the pop-
pet seat retainer. The tungsten carbide seat and
needle may pop out because of the spring force ap-
plied against them.
6. Inspect the needle and seat assembly [4] for
wear. If wear or damage is evident, replace. Replace
both needle and seat at the same time because they
are a matched set. Inspect o-ring (5) for damage,
replace as necessary.
7. Reassemble the fluid regulator by inserting the
spring [3], needle and seat [5] back into the regulator
block assembly. Be sure to lube o-ring. Secure the
needle/seat assembly by screwing the seat retainer
[4] into the regulator block assembly until a torque
of 8-10 lbs•in is obtained.
8. When replacing the diaphragm [2], remove the
screw [9] that holds both halves together. Inspect
o-ring [6] for damage. To reassemble, make sure that
the side is toward the lower support [8]. Reinstall
screw and tighten. Be careful not to over tighten. If
the diaphragm is inserted wrong, damage will occur.
Push the diaphragm assembly down in valve body
aligning the screw holes.
