2. INSTALLATION

2.1 Unpacking

Unpack the following items:

• T31P or T31XW Indicator

• AC Adapter (T31P only)

• Mounting Bracket (supplied with T31XW only)

• Knobs (2) (supplied with T31XW only)

• Capacity Label Sheet

• Instruction Manual CD

• Warranty Card

• LFT sealing Kit

2.2.2 AC Power to T31P

Connect the AC Adapter to the power receptacle (Figure 1-1, item 8), then plug the AC Adapter into an electrical outlet.

2.2.3 AC Power to T31XW

Connect the AC plug to a properly grounded electrical outlet.

EN-113000 Series Indicators

2.2.4 Battery Power

The indicator can be operated on the internal rechargeable battery when AC power is not available. The indicator will automatically switch to battery operation if there is a power failure or the power cord is removed.

Note: Before using the indicator for the first time, the internal rechargeable battery should be fully charged for up to 12 hours. The indicator can be operated during the charging process. The battery is protected against over charging and the indicator can remain connected to the AC power line.

Connect AC power to the indicator and allow it to charge. While the battery is charging, the triangle above the battery function symbol will light. When the battery is fully charged, this triangle will disappear.

The indicator can operate for up to 100 hours on a fully charged battery.

During battery operation, a flashing triangle above the battery function symbol indicates the battery is low and requires recharging. Approximately 60 minutes of operation will remain when the battery symbol starts to blink. The indicator will display Lo.BAT and automatically turn off when the battery is fully discharged.

CAUTION

BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED OHAUS SERVICE DEALER.

RISK OF EXPLOSION CAN OCCUR IF REPLACED WITH THE WRONG TYPE OR CONNECTED IMPROPERLY.

Dispose of the lead acid battery according to local laws and regulations.

2.2.5 Mounting Bracket to T31XW

Align the mounting bracket over the threaded holes in the side of the indicator and install the knobs. Adjust the indicator to the desired angle and tighten the knobs.

2.3 Internal Connections

Some connections require the housing to be opened.

2.3.1 Opening the Housing

CAUTION: ELECTRICAL SHOCK HAZARD. REMOVE ALL POWER CONNECTIONS TO THE INDICATOR BEFORE SERVICING OR MAKING INTERNAL CONNECTIONS. THE HOUSING SHOULD ONLY BE OPENED BY AUTHORIZED AND QUALIFIED PERSONNEL, SUCH AS AN ELECTRICAL TECHNICIAN.

EN-12 3000 Series Indicators

T31P

Remove the four Phillips head screws from the rear housing. Open the housing being careful not to disturb the internal connections. Once all connections are made, reattach the front housing.

T31XW

Remove the four hex head screws from the rear housing. Open the housing by carefully pulling the top of the front housing forward. Once all connections are made, reattach the front housing. The screws should be tightened fully to maintain a watertight seal.

2.3.2 Scale Base to T31P or T31XW

Pass the load cell cable through the strain relief (Figure 1-1, item 9 or Figure 1-2, item 10) and attach it to terminal block J5 (Figure 1-3, item 5). Re-tighten the strain relief to ensure a watertight seal.

Jumper Connections

For a 4-wire load cell with no sense wires: Jumpers W2 and W3 must be shorted. For a 6-wire load cell that includes sense wires, see Figure 2-2. Jumpers W2 and W3 must be opened. For load cells with an extra ground shield wire: Connect the shield to the center position (GND) of J5.
