9040 Cascade Low Voltage Control Unit - Maintenance

> In the control unit, ground is passed

from the ground stud to the chassis via

the front panel screws. Ensure the front

panel screws are securely fastened and

repeat step 3 before searching for faulty

internal connections.

MAINTENANCE

In general, little maintenance is necessary to

ensure proper operation. It is important, however,

to keep the interior of the unit clean and free from

moisture or foreign material. For this reason:

• Keep the exterior of the unit free from dust

accumulation.

• Always clean the exterior prior to accessing the

interior.

• Access the interior only to perform mainte-

nance or repair

If shocks or sparks are noticed at any point in the

spray system, immediately turn off the control unit

and check the complete system for proper

grounding. Proper grounding of the applicator

system can be verified as follows:

1. Ensure that the clamp of the Ground Wire

Assembly is connected to true earth ground. The

resistance between the clamp and a known earth

ground should read less than 25 ohms.

2. Place one end of the ohmmeter on the clamp

of the ground wire assembly and the other end on

the control unit ground stud. If the ohmmeter reads

greater than 25 ohms replace the Ground Wire

Assembly.

3. Disconnect the low voltage applicable cable and

connect one lead of the ohmmeter to the ground

stud and the other to the center pin of the low

voltage cable socket on the control unit. If the

ohmmeter reads greater than 25 ohms, repair the

internal connections between these points (green

wires from 1TB-GROUND TO 1GND (see Figure

10) and from 1TB-GROUND to center pin of low

voltage cable socket).

4. Connect one end of the ohmmeter to the center

pin of the low voltage cable connector on the cable,

and the other to the metal applicator body

(automatics) or handle bracket (applicators). If

the ohmmeter reads greater than 25 ohms replace

the low voltage cable.

> On applicators, ground is passd from

the low voltage cable to the handle via the

handle set screw. Ensure the set screw

is completely tightened and repeat step 4

before replacing the low voltage cable on

applicator units.
