2. INSTALLATION

2.1 Unpacking and Checking

Open the package and remove the instrument and the accessories. Check the completeness of the delivery. The following accessories are part of the standard equipment of your new Indicator.

Remove packing material from the instrument.

Check the instrument for transport damage. Immediately inform your Ohaus dealer if you have complaints or parts are missing. Your Indicator package should contain:

 Indicator CW-11  Warranty card  Capacity label  Screw driver for terminal connections  Instruction Manual  lead seal for weights and measures sealing

Store all parts of the packaging. This packaging guarantees the best possible protection for the transport of your instrument.

2.2 Selecting the Location

The Indicator should be used in an environment which is free from corrosives, vibration or temperature extremes. These factors will affect displayed weight readings. Scale bases used with the Indicator should be located on a stable level surface and kept away from vibrating sources such as large machinery. Maximum accuracy will be achieved when the area is clean and vibration free.

2.3 Connecting the Indicator to a Scale Base

At the bottom of the back cover of the Indicator are two slots. There is a spring clip at each slot location which holds the cover in place. Insert the small scewdriver blade into each slot and press and work the back cover off. With the cover removed, proceed as follows:

Remove the rear cover. Inside is the battery compartment which is wired to the PC board underneath.

Remove batteries if installed.

Remove the four corner screws from the battery board. One of the screws is crossed drilled to accept a wire seal when used for legal for trade applications.

Carefully lift the battery board up and out of the indicator. The wires can be disconnected from the main PC board by unplugging the connector.

Pass the load cell cable through the large or small liquid tight connector on the bottom of the housing. (Depending on cable size.)

2.3 Connecting the Indicator to a Scale Base (Cont.)

Refer to the color code of the load cell cable and connect the wires to Terminal Strip J4. Tighten all screws securely. The connections are shown for a 6 wire cable. When a 4 wire cable is used, the Jump 1 and Jump 2 jumpers on the PC board

For obtaining better performance, it is recommended to keep both JUMP 1 and JUMP 2 jumpers open when a 6-wire load cell is connected to the CW-11.

2.4 Communication Connections

Provisions are made in the Indicator to communicate with an external computer or printer using an RS232 protocol. To connect, proceed as follows:

Pass the communication cable through one of the liquid seal connectors at the bottom of the Indicator.

Connect the cable to the J10 connector on the PC board. Observe the functions and connect correctly.

Connect the opposite end of the cable to the device.

After all connections have been made to the main PC board, replace the battery cover and lightly secure with the four screws previously removed. If the Indicator is to be used in a legal for trade application, you will have to gain access to the legal for trade switch on the main PC board again after all Indicator settings have been made. Once this is done, the rear cover can be replaced.

2.5 Cautionary Notes

Model CW-11 Indicator must not be operated in hazardous areas.

Before connecting AC power, verify that the Indicator operating voltage corresponds to the local mains voltage. If this is not the case, check terminal board J9 connections on the main PC board. There are provisions for 110V or 220V operation. Please contact your local Ohaus dealer if the voltages do not match.

Model CW-11 Indicator may be used in a washdown environment.

The CW-11 Indicator may be operated using the AC power cord , or 6 Alkaline C-type batteries (not supplied). When the Indicator is plugged into a power source, the batteries are automatically disconnected. In the event of a power failure, the batteries if installed will automatically continue to operate the balance.

2.6 Connecting Power

2.6.1 Battery Installation

With the back cover removed from the Indicator, insert 6 Alkaline C-type batteries into the battery holder making sure that the batteries are properly orientated (correct polarity).

NOTE: It is recommended that when the CW-11 is operated from batteries, the Auto-Off Timer feature be

turned on to extend battery life. When setting up the Indicator, refer to Intial Setup,Readout menu, paragraph 2.8.5.

2.6.2 AC Power

Connect the AC power cord from the Indicator and plug into a convenient power outlet.

NOTICE:

The socket/outlet must be installed near

the equipment and shall be easily accessible.

2.6.3 Operating the Indicator

Once the Indicator and Scale Base are connected and installed, follow the setup procedure outlined below.

Power On/Off

With the Indicator connected to an appropriate power supply, press the ON/ZERO/OFF button. The Indicator performs a self-test, indicates the software revision momentarily and then goes to a weighing mode. At this point, the Indicator is on and ready for initial setup.

Stabilization

Before initially using the Indicator, allow time for it to adjust to its new environment. Recommended warm up period is five (5) minutes.

2.7 Setup Protection

The CW-11 Indicator is equipped with menus which permit certain functions to be locked out (not changed) during operation. If you intend to lock out changes to the setup selections you make, do not re-assemble the indicator. You will need to access the cal jumper located on the main PC circuit board following the setup procedure.

2.8 Initial Setup

For first time setup, step through all menus and set the parameters as desired. As the last step, enter the CAL menu and calibrate the system.

The indicator has five menus; CAL, SETUP, READ, PRINT and LOCSW which are entered by pressing and holding the G/N/T/MENU button until MENU is displayed, then releasing it. The display then switches to CAL. To access the rest of the menus, the PRINT/UNITS button is repeatedly pressed until the desired menu is reached.

2.8.1 Control Functions
