MAIN BOARD POWER JUMPERS

Caution: The meter has no power-on switch, so it will be in operation mode as soon as you apply power. Typically the meter is shipped per order (per the part number requested) and no modification is necessary. However, if you want to check voltage jumpers, or to change from 115 Vac to 230 Vac (refer to Figure 3-8). Verify that a duplicate set of wire jumpers are not on the bottom side of the transformer.

Disconnect the power from the unit before proceeding.
1. Remove the main board from the case.
2. Locate the wire jumpers W1, W2 and W3 (located near the edge of the main board alongside the transformer).
3. If your power requirement is 115 Vac, install solder jumpers W1 and W2, but do not install jumper W3. If your power requirement is 230 Vac, install solder jumpers W3, but do not install jumpers W1 or W2.

AC Power Failure Provision
To store a total count in the nonvolatile memory if an ac power loss occurs set the S1-10 switch to "open". When ac power resumes the meter displays the total at the time of the power loss, and then resumes totalizing.

DC Power/Backup Battery Provision
You may power the meter from an external dc power supply, or an external battery. The typical current requirement is 260 mA at 7.5 to 13 Vdc to maintain full operation and meter display when no option board is installed. You can shut off the display without affecting any meter functionality by setting the S1- 10 switch to open. Shutting off the digital display reduces the current requirement to 30 mA (if option boards are installed, add 180 mA for an analog output board, 120 mA for a dual-relay board, and 20 mA for an RS232 board).

Caution: If the S1-10 switch is in the "closed" position, the meter does not detect any power loss (ac or dc), and therefore will not load the display data into the nonvolatile memory. In this case the Total is loss when both ac and dc power are lost.

MOUNTING THE METER

Figure 3-10. Meter - Exploded View

Figure 3-11 Panel Cut-Out

1. Cut a hole in your panel, as shown in Figure 3-10. For specific dimensions refer to Figure 3-11.
2. Insert the meter into the hole. Be sure the front bezel is flush to the panel.

Refer to Table 6-1 for summary list of menu configurations.

SELECTING MAIN MENU ITEMS
1. Press the MENU button. The meter shows a main menu item. Continue to press the MENU button to scroll through main menu items.

2. Once the desired main menu item shows, press the SET button to show the item's current value or the active sub-menu item.

SELECTING SUB-MENU ITEMS
1. Select main menu item.

2. Once the meter shows the correct main menu item, press the SET button. The meter shows either the active sub-menu item or the main menu item's current value.
3. If the meter shows an available sub-menu item, press the ADV button to show the sub-menu item's current value.

Note: The main menu items "OFFSET" and "COnFIG" do not have sub-menus. If you press the SET button when the meter shows either of these items, the meter will show the current number value.

4. Press the SET button to change the flashing number value. The left-most digit (above the RECALL button) may be set to a minus sign. Also, press the SET button to change the decimal point position.

5. Press the ADV button to change which digit is flashing.

SAVING CHANGES
You may store (save) meter changes in the volatile and nonvolatile memory. Remember you cannot store changes in the nonvolatile memory without first storing them in the volatile memory.

To store changes in the nonvolatile memory, follow these steps:
1. Make required changes, using the ADV button to show current values and also to move from left to right through the digital display. The digit or value that may be changed will flash. Use the SET button to change the function, number value or decimal point of the flashing item.

2. Press the MENU button until the meter shows "noStor".

3. Press the SET button. The meter shows "StorE".

4. Press the MENU button to store the changes to the nonvolatile memory. If power loss occurs, or meter is hard reset these changes stay in the meter's memory.

To store changes in the volatile memory, follow these steps:
1. Make required changes, using the ADV button to show current values and also to move from left to right through the digital display. The digit or value that may be changed will flash. Use the SET button to change the function, number value or decimal point of the flashing item.

2. Press the MENU button to store changes to the volatile memory.

3. Press the RESET button to operate the meter from the volatile memory.
