9040 Cascade Low Voltage Control Unit - Installation
3. Using a small blade screwdriver, remove the
factory installed test jumper from 1TB-L1 to 1TB-
L2.
4. Route exhaust fan and conveyor interlock
(supplied by user) wiring through external wiring
grommet on the back of the control unit and
connect to 1TB-L1 and 1TB-L2 as shown in Figure

5. Slide the chassis back in, secure the front panel
screws, replace the fuse, and plug the control unit
in.
> When highly conductive, solvent-
based paints are used it is also recom-
mended that the high voltage control be
series interlocked with the atomization
air. This prevents the possibility of a
charged stream of fluid creating an arc,
and subsequent fire, as it approaches
the floor (or some other grounded
object). Consult your authorized ITW
Ransburg representative for information
on interlocking the high voltage with the
atomization air.

is unplugged from its AC outlet before working
with any internal wiring connected to 1TB-L1,
1TB-L2, 1TB-N, 1FU, 1SW, or 8PL.

As outlined in NFPA-33 and OSHA, the AC power
line must be series interlocked with both the
exhaust fan and conveyor. To interlock the 9040
Cascade control unit with the exhaust fan and
conveyor perform the following:
1. Ensure the front panel fuse is removed, the
control unit is unplugged, and the ON/OFF switch
is in the OFF positon.
2. Loosen the front panel screws and slide the
control unit chassis out.

A set of external relay contacts for high voltage
(K1) and overload (K2) conditions is provided at
External Wiring Plug 2PL-5, -6 & -7 (outside) and
2SOC-5, -6 & -7 (inside). (See Figure 11 for exact
wiring locations.) These relay contacts are
sometimes useful in configuring the control of the
spray applicator system.

Connect the Air Filter Assembly (supplied) to the
IN port of the air flow switch on the back of the
9040 Cascade control unit. Connect regulated
(100 psi maximum) factory air to the other end of
the Air Filter Assembly. Be sure that the fittings
remain clean and are securely tightened. Attach
the spray applicator air line to the OUT port of the
air flow switch.
When the spray applicator is triggered, the resulting
air flow closes the contacts of the air flow switch,
thereby activating high voltage at the spray
applicator.

Connect an atomization air pressure signal to one
pressure switch port and a trigger air pressure
signal to the other. When pressure signals are
applied to both switches, their contacts close
thereby activating high voltage at the spray
applicator. Both pressure switches must be
activated to receive high voltage. Pressures
greater than 15 psi are required to activate the
pressure switches. Maximum operating pressure
is 150 psi.
