OVERVIEW

nnnn

Walchem's WCU410 Copper Controller and WNI Nickel Controller are opto-

nnnn

electronic on-line analyzers that measure the actual concentration of copper

nnnn

or nickel in solution. They are used in a variety of applications including

nnnn

electroless plating baths and microeth baths (including oxide-replacement

nnnn

types).

nnnn

The WCU410 may be switched from electroless copper to microetch via

nnnn

the menu, eliminating the need for a second controller. It reduces the need

nnnn

for manual titration, improves yield, and in microetch applications improves

nnnn

productivity by reducing the frequency of bath change-outs.

nnnn

The WNI41 0 is available as nickel-only, or with a pH control option which

nnnn

may be added in the field. Two separate pump outputs for nickel and

nnnn

reducer and another for pH are used, each of which is capable of totalizing

nnnn

either pump on-time, volume pumped, or metal turnovers.

nnnn

Integrated datalogging is available to validate system performance. A

nnnn

USB memory stick is all that's needed to extract data and event logs that

nnnn

include copper or nickel measurements, and relay status. Download logs

nnnn

from the USB stick to a PC at your convenience. It couldn't be easier!

SUMMARY OF KEY BENEFITS

nnnn

©

nnnn

Concentration Read in Units

nnnn

Selectable between grams per liter (g/L) or ounces per gallon (oz/gal). Backlit digital display also acts as a

nnnn

bar graph for a continuous "visual summary" of measurement versus set point.

nnnn

Operator Adjustable

nnnn

Concentration set point, alarm set points (high and low), dead band and pump on time are all easily adjustable.

nnnn

An interlock feature allows external devices (such as a flow switch ) to interlock control relays.

nnnn

Simple, Integrated Data Collection

nnnn

Download stored data from the controller to a USB stick. Use the data to simply and easily P*

nnnn

validate system performance. The data and event logs show copper or nickel values, as

nnnn

well as accumulated chemical feed and relay activation times.

Four Separate Control Relays & Outputs (WCU)

nnnn

May be used to add copper, caustic, formaldehyde or chelator/stabilizer chemistries. Each output has a

nnnn

replenishment totalizer which may be set in units of time or volume.

nnnn

Optional pH Input Board (WNI)

nnnn

May be used to add pH adjustment chemistry. Output has a replenishment totalizer which may be set in units

nnnn

of time or volume.
