9040 Low Voltage Control Unit Kit- Installation
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 position.
2.
Loosen the front panel screws and slide the
control unit chassis out.

Always double check that the control unit
is
unplugged from its AC outlet before working
with any internal wiring connected to 1TB-L1,
1TB-L2, 1TB-N, 1FU, 1SW, or 8PL.
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 2.
2.
The interlock contacts should be rated for
at least 1 amp at 240 volts AC.
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 recommended
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 Ransburg
representative for information on
interlocking the high voltage with the
atomization air.

External Relay Contacts
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.
Maximum contact ratings are as follows:
DC
AC
Maximum Switching Power
60W
125VA
Maximum Switching Voltage
220VDC 250VAC
Maximum Switching Current
2A
