Eaton Ambassador Counter Complete Guide

Switch 4: Input B threshold level. OFF: High threshold level (for DC sensors); ON: Low threshold level (used for magnetic sensors, switch 2 needs to be turned on at the same time).

3.3 General wiring specifications

Power off operation: All power sources must be disconnected before wiring.

Use shielded cables: for counting signals, controlling inputs, and communication signals. Connect the shielding layer to the common terminal of the counter (terminals 2, 3, or 4).

The signal line should be as short as possible.

Separate laying: Do not bundle signal lines with power lines or machine control lines in the same cable tray. Use a separate catheter.

Provide a "clean" power supply: Use a power filter or separate power supply if necessary, and do not share the same power supply with the load.

AC power cord: Use 18 AWG (minimum) to 14 AWG (maximum), 600V wire.

3.4 Panel Installation

The panel installation kit includes: 1 mounting washer, 2 mounting clips, and 4 screws. The installation steps are as follows:

Place the counter display screen facing downwards.

Remove the center block of the gasket along the scratch line and keep the outer paper back.

Slide the gasket to the back of the front frame of the device, with the paper back facing upwards.

Pry open the paper back and washer with the tip of the knife, while holding down the washer and tearing off the paper back.

Push the device into the panel opening until the gasket firmly adheres to the panel.

Install the clamps and screws, do not tighten them too tightly to avoid squeezing the washers.

Panel opening size: 2.68 "x 2.68" (68mm x 68mm). NEMA 4 protection level requires the use of the provided gasket.

Programming mode

4.1 Programming Mode Navigation

All programming is completed through the front panel keyboard. After entering programming mode, the display screen shows the main menu item PROGRAMM SCALERS. Use the up/down arrow keys to scroll through the main menu, and use the SELECT and EXIT keys to enter or exit submenus and editing layers.

Attention: Entering programming mode will cause all outputs to shut down. It is necessary to stop the process before entering programming mode.

4.2 Main menu structure

The programming menu of Ambassador is divided into the following main parts:

PROGRAMM SCALERS: Scaling Factor Settings

Program COUNT IN: Count Input Configuration

Program INPUTS: Control input function allocation

Program OUT MODE: Output Mode Configuration

Program Display: Screen Selection for Running Mode Display

Program Text: Customize Display Text

Program SER PORT: Serial Port Configuration

Program SER OUT: Serial Output Content Selection

Program Options: Other options (reset key function, print key function, load default values, etc.)

4.3 Key Programming Options

4.3.1 Scalers

Counting scaling factor (C SCALER): determines the count value of each input pulse. The range is 0.00001 to 9.99999, with a default of 1.00000. Calculation formula: CS=DPF/PPI, where DPF is the decimal factor (depending on the decimal place) and PPI is the number of pulses per term.

Counting decimal point (C DEC PT): Set the decimal point for the main counter and accumulator.

Rate scaling factor (R SCALER): used to adjust the reading of the rate meter. Range 0.00001 to 99999, default 1.0000. Calculation formula: RS=(SEC x DPF)/PPI, where SEC is the number of seconds corresponding to the rate time unit (e.g. 60 per minute).

Rate decimal point (R DEC PT): Set the decimal point for rate display.

ZERO TIME: If there are no pulses within this time, the speedometer is forced to zero.

Rate Average Time (R AVG TIME): Set the minimum rate update time.

4.3.2 Counting input mode

Program item 10 selects counting mode, with a total of 11 options available, such as:

CNT&TOT A-B: Input A to increment the main counter and accumulator, input B to decrement them.

CNT&TOT A+B: Both inputs A and B cause the main counter and accumulator to count up.

CNT&TOT QUAD X1/X2/X4: Orthogonal encoder counting mode, counting 1, 2, or 4 times per cycle.

TOT A CNT B: Input A counts the accumulator, input B counts the main counter.

The response speed of inputs A and B can be set to solid-state (high speed) or contact (≤ 40 Hz), respectively.

4.3.3 Control input function

The four control inputs can be assigned the following functions (taking input 1 as an example, inputs 2-4 are the same):

Disabled: Disabled

BYP P1: When input 1 is turned on, the counter ignores the preset 1

OUT CTL1/2: When input 1 is turned on, trigger output control 1/2 event

RS C EDG/LVL: edge/level triggered main counter reset

RS B EDG: Edge triggered batch counter reset

RS T EDG: Edge triggered accumulator reset

RS A EDG: Edge triggered reset of all counters

STOP CNT: Level triggered stop counting

PRIMT: Edge triggered serial output list transmission

LOCK PGM: Level triggering prohibits program editing

LOCK ALL: Level triggering prohibits all programming and preset editing

UNL ALMS: Level triggered shutdown of all rate outputs

4.3.4 Output Configuration

Each output (relay 1, relay 2, transistor 1, transistor 2) can be individually configured:

Choose based on count or rate:

Count output: Acting at preset values and/or specific events (such as reset count, output control input).
