R“ ” - To the left of the display is the rate value.

- Counter A has no designator.

b“ ” - To the left of the display is the Counter B value (dual count or batch).

“1” and “2” - Indicates setpoint 1 and 2 output status.

Pressing the SEL button toggles the meter through the selected displays. If display scroll is enabled, the display will toggle automatically every four seconds between

the rate and count values.

PROGRAMMING MODE ENTRY (SEL KEY)

It is recommended all programming changes be made off line, or before

installation. The meter normally operates in the Display Mode. No parameters

can be programmed in this mode. The Programming Mode is entered by

pressing and holding the SEL key. If it is not accessible then it is locked by

either a security code, or a hardware lock.

MODULE ENTRY (SEL & RST KEYS)

The Programming Menu is organized into separate modules. These modules

group together parameters that are related in function. The display will alternate

between Pro and the present module. The RST key is used to select the desired

module. The displayed module is entered by pressing the SEL key.

MODULE MENU (SEL KEY)

Each module has a separate module menu (which is shown at the start of each

module discussion). The SEL key is pressed to advance to a particular parameter

to be changed, without changing the programming of preceding parameters.

After completing a module, the display will return to Pro NO. Programming may

continue by accessing additional modules.

SELECTION / VALUE ENTRY

For each parameter, the display alternates between the present parameter and

the selections/value for that parameter. The RST key is used to move through the

selections/values for that parameter. Pressing the SEL key, stores and activates the

displayed selection/value. This also advances the meter to the next parameter.

For numeric values, press the RST key to access the value. The right hand

most digit will begin to flash. Pressing the RST key again increments the digit

by one or the user can hold the RST key and the digit will automatically scroll.

The SEL key will advance to the next digit. Pressing and holding the SEL key

will enter the value and move to the next parameter.

PROGRAMMING MODE EXIT (SEL KEY)

The Programming Mode is exited by pressing the SEL key with Pro NO

displayed. This will commit any stored parameter changes to memory and

return the meter to the Display Mode. (If power loss occurs before returning to

the Display Mode, verify recent parameter changes.)

PROGRAMMING TIPS

It is recommended to start with Module 1 for counting or Module 2 for rate.

When programming is complete, it is recommended to record the parameter

programming and lock out parameter programming with the user input or

programming security code.

FACTORY SETTINGS

Factory settings may be completely restored in Module 3. This is useful when

encountering programming problems.

ALTERNATING SELECTION DISPLAY

In the explanation of the modules, the following dual display with arrows will

appear. This is used to illustrate the display alternating between the parameter

on top and the parameter’s factory setting on the bottom. In most cases,

selections and values for the parameter will be listed on the right.
