PROGRAM TOTALIZER

Sub Menu 21 - Totalizer Remote Control Inputs

Any of the five rear terminal control inputs can be programmed to perform a function in the totalizing
operation. A control input is selected by pressing front panel keys 1, 2, 3, 4 or 5. Key 1 selects control
input 1, key 2 selects control input 2, etc. When a control input terminal has been selected, it is shown
on the left hand side of the display and its function is shown on the right hand side of the display. The
function that a control input terminal performs can be changed by pressing the up arrow key. The
functions that can be assigned to an input are None, Reset Count, Unlatch Output, or Reset Count &
Unlatch Output. Note: an input assigned to perform a function to the totalizer can also be assigned to
perform additional functions to the rate meter in the rate meter menu row. A chart is shown on page
12 to provide a convenient means of recording the tasks each control input has been assigned.

Sub Menu 22 - Totalizer Pulse Output

The totalizer pulse output transistor can be programmed for fast, medium, or slow pulse widths. It can
also be programmed to not output pulses.

Frequency Range of Output

Fast - 125

sec, 1500 Hz max. output frequency. (Typical factory setting).

Medium - 2 msec on, 200 Hz max. output frequency

Slow - 50 msec on, 10 Hz max output frequency

No Pulse - Off Continuously

This output has a 255 count buffer. The buffer is saved at power down, and is reset when the totalizer
is reset. Use the up arrow key to select the mode of operation of the scaled pulse output.

Sub Menu 23 - Totalizer Setpoint Time-Out

The totalizer setpoint output transistor can be programmed to time out in the range of 0.01 to 99.99
seconds. To enter a time value, press the Clear key, enter the time with the 0 through 9 keys, and press
the Enter key. The timer can be disabled by setting a time value of 0.00 seconds. When the timer is
disabled, the output remains latched until an input or keyboard command unlatches it. (The typical
factory setting is 0.00 seconds).

Sub Menu 24 - Reset Key

The Reset key can be programmed to perform various functions on the totalizer operation. The name
of the key is shown on the left side of the display and the function it performs is shown on the right
hand side of the display. The options are: Reset Count, Unlatch Output, Reset & Unlatch, or None.
The function can be changed by pressing the up arrow key. Keys assigned to perform a function on
the totalizing operation may also be assigned to perform additional functions to the rate meter. A chart
is shown on page 12 to provide a convenient means of recording the tasks of the Reset key. (The
typical factory setting is reset and unlatch).

Sub Menu 25 - Totalizer Decimal Point

The totalizer display can have a decimal point programmed in any of six positions. Use the 0-5 keys
to select the desired position. The decimal point selected here is shown in the total count and totalizer
setpoint displays. Please note: Placement of the decimal point on the display does not rescale the
programmed K-factors. See Sub Menu 11.
