INTRODUCTION

This manual describes the Ambassador 5760X-405 count control, and is intended to be a guide in the installation and operation of the control.

The control itself is like an electronic erector set, full of counter and ratemeter "parts" which the user must "assemble". The majority of this manual is concerned with installation, describing the parts of the counter, helping the user determine the wiring and programming necessary to "assemble" his counter into the tool he needs to do a specific job, and documenting those choices. The operation section, which describes the operator functions, follows in the section Run Mode. The following description of the control and the block diagram is recommended reading for those new with this device. Those installers who are familiar with controls and counter terminology are welcome to attack the Quick Start section after examining the block diagram. The Quick Start uses a logical inputs-to-outputs approach to decide how to wire and program this control to do the job. Detailed programming and wiring information follow the Quick Start section, providing guidance to the first time installer.

MAIN COUNTER

The main counter is a six digit, bi-directional count register designated by the letter C on the display. The user can assign up to four presets to this counter. The main counter is the workhorse of this control. Note its central location in the block diagram and the number of "connections" to it. This register increments and decrements from scaled count input pulses. The "favored" count direction is up in reset to zero mode and down in reset to final preset mode. The favored count direction feature affects only the function of the count inputs, and the direction of the totalizer count, and the preset selected for the current preset display. The main count display screen can be customized to identify what type of units are being counted.

RATEMETER

The control uses the frequency of the count pulses at input A to calculate rate. The rate scaler accommodates the "weight" of each pulse and the time units in order to display rates such as revolutions per minute, barrels per hour, etc. The ratemeter average and zero times are programmable. Two alarm setpoints are assigned to the ratemeter. The rate display text can be customized.

OUTPUTS

Two form C relay and two open collector NPN transistor outputs are available. Each output is individually assignable to rate or count. Count outputs can turn on or off at any combination of eight preset and control events. These outputs can be timed or latched, and each has a programmable on-delay timer. Rate based outputs turn on based upon comparison to one of two rate alarm setpoints. Rate outputs turn off after timeout (pulsed), external control signal (latched), or when the rate crosses the setpoint back to the non-alarm state (follows).

COUNT INPUTS

Count inputs A and B are DIP switch settable to accept sinking or sourcing single ended DC or differential count signals. Input A is used by the ratemeter. Inputs A and B are programmable to affect the main counter and totalizer in eight count modes and three count/control modes.

CONTROL INPUTS/RESET KEY

Four control inputs are available. These inputs are single ended DC, sink only and are programmable to one of 14 functions. The reset key may be programmed to reset one, all, or none of the count registers.

TOTALIZER

The totalizer is an eight digit, bi-directional count register that counts in parallel with the main counter. The totalizer counts up when the main counter counts in the favored count direction, and down when the main counter counts in the nonfavored direction. The totalizer display can be customized to show units of count. The totalizer does not have preset or output capability.

BATCH COUNTER

The batch counter counts the number of "batches" of the main counter, incrementing every time the main counter autocycles or reaches the final preset. This register is six digits and counts up only. The batch counter has one preset, and always autocycles whenever it reaches the setpoint. The batch count display can be customized to show units of count.

RS 485 SERIAL COMMUNICATIONS

The control uses RS-485 serial communications in either host mode: to respond to a host computer, or printer mode: to dump selected values to a printer. The print transmission is initiated by either the Print key or a control input. The communication capability is described in a separate manual. If you need information on the serial communications, contact the Literature Department at 1-800-540-9242.

FEET/INCHES CONTROL

Models 57601-415 (green display) and 57601-465 (red display) have a readout in feet and inches with a fixed decimal point separating them. These models also have a floating prewarn that adjusts itself to the final preset. See page 33 for more details.

The block diagram shows the major internal "parts" of the control. A general description of each block was given on the previous page. The block diagram shows how the parts relate to each other. The flow through the control is generally left to right; inputs are designated by screw terminal number on the left side of the block, and output terminals are shown on the right side. In between, arrows lead from block to block from the count inputs (19 and 20) to the count and rate registers. The open ended arrows indicate "connections" that can be made by programming.

Feet/Inches control.

The block diagram shows that the control will not respond to the control inputs; (15, 16, 17, 18 and RST key) until they are programmed to a specific function, and the outputs are also oblivious to the count and rate registers until a programming "connection" is made.

INSTALLATION WIRING AND PROGRAMMING - QUICK START

This section is a step-by-step process for determining program selections and I/O wiring. If the installer has a basic knowledge of counter terminology and uses the block diagram for a reference, the configuration process should be straightforward. Detailed descriptions of programming choices are listed on pages 22 to 25. Detailed I/O wiring diagrams are shown on pages 26 to 28. Instructions on calculating scale factors are on page 29.

For each programming choice, a program item number is listed. A selection space is provided to record the desired selection. These numbers can be also recorded in the programming menu chart on pages 14 to 21, in order to

document the application.

Record the selections you have made that are not the default value in the program menu chart on pages 14 to 21. After you wire the counter up according to the diagram on page 10, go into the program mode and give your counter the personality to do your application.

Phase III - Above and Beyond

A phase 3 installation uses the serial communications port in the host mode. This capability allows a host computer to read all programming and run mode information and to write all programming selections. Furthermore, all of the control input functions are available through the serial port.

A separate manual describing the serial communications is available. If you would like a copy, call 1-800-540-9242.

TERMINAL DESCRIPTIONS 1 - On models 57601 and 57602 this terminal is the +12 VDC

power output. It is used to supply 12 VDC (+/- 25% 100 mA max) for accessories. DC Common is the negative side of this supply.

On the model 57600 this terminal is used for the 10-15 VDC power input. Connect the positive lead of the power supply to terminal 1 and the negative lead to DC Common.

The DC POWER OUTPUT contains a series Positive Temperature Coefficient (PTC) resistor that undergoes a large and abrupt increase in resistance when an over-current condition occurs. This resistance change limits the fault current to several milliamps. The PTC device will reset when the unit power has been removed for a time sufficient to cool the device. The overload condition should be removed before unit power is reapplied.

2, 3, and 4 - DC Common: These terminals are connected to the negative side of the counter’s internal DC power supply. Count inputs must be referenced to DC Common. Control inputs are on when connected to DC Common. Transistor outputs conduct to DC Common when picked up.

5, 6 and 7 - Relay 2 contacts 8, 9 and 10 - Relay 1 contacts

Each relay output consists of one electrically isolated form C set of contacts. The user must supply power through a contact to the external load. The contacts remain in the

15, 16, 17, and 18 - Inputs 1, 2, 3, and 4: Programmable inputs. The user can assign one of 14 functions to each individual input. The inputs require a current sinking signal (contact or solid state) to DC Common (see input programming diagram page 15 and block diagram page 2).

19, 20 - Count Inputs B and A: Connect the count input signal(s) to these terminals. The count input can operate with either a current sinking signal (contact or solid state) to DC Common or a current sourcing signal. (See specifications, programming diagram page 14, and block diagram page 2.) Rate calculations are made from count pulses into Input A only.

REAR TERMINAL DESCRIPTION continued

MODULAR COMMUNICATION JACK

The modular phone jack is an alternate connection to the RS485 communications port. Pin 3 is positive and is the same as terminal 21. Pin 2 is negative and is the same as terminal

22. Pins 1 and 4 are connected to DC Common and should be used for any shield connections.

Note: This jack is intended only for connection to Ambassador and other RS-485 communication networks. It should

not be connected to any telephone system - damage or hazard may result.

TERMINAL BLOCKS

Connections to the Ambassador are made through deplugable, screw terminal blocks to allow for ease of wiring and removal of the counter. The terminals can accommodate stranded, solid or fused wire (preferred) from 14 to 22 gauge.

To remove the terminal block, remove AC power and pry gently underneath each end of the terminal block with small screwdriver. Press straight on to re-install.

GENERAL WIRING PRACTICES

1. Disconnect all power before wiring terminals. A

safety hazard exists if this precaution is not

observed. Treat all control and count inputs as hazardous since they may carry line voltage.

2. Use shielded cables for count signals, control input and communications signals. Connect shield to common (terminal 2, 3 or 4) of counter to terminate properly.

3. Keep all signal lines as short as possible.

4. Do NOT bundle or route signal lines with power or machine control wiring. Use separate conduit for power and signal wires.

5. Provide "clean" power to the counter. In severe cases, power may have to be filtered or a separate power source used. Do not use the same power source that is supplying the loads.

6. Use 18 ga. minimum (0.97mm maximum (2.1mm2, 600V) wire for AC power wiring.

7. See page 26, top drawing, for the correct fuse to be used in the power input wiring.

DIP SWITCH FUNCTIONS

Switch 1: Input A sink/source

Off: input A requires a current sinking input signal. On: input A requires a current sourcing input signal.

Switch 2: Input B sink/source

, 600V) and 14 ga.

Switch 3: Input A threshold level

Off: high threshold level — use with DC sensors. On: low threshold level — use with mag pickups. Turn

switch 1 on.

Switch 4: Input B threshold level

Off: high threshold level — use with dc sensors. On: low threshold level — use with mag pickups. Turn

switch 2 on.

Dip switches may be set through an opening on the bottom of the unit. It is located towards the rear of the control.

PANEL MOUNTING

The panel mounting kit includes: (1) mounting gasket, (2) mounting clips and (4) screws.

Refer to the dimension diagram on page 37 for a drawing of the correct installation of these parts.

The mounting gasket is coated on one side with a contact adhesive and a paper backing. Care should be taken during the gasket installation that the gasket be correctly positioned on the panel at the first attempt. Attempting to re-position the gasket once the adhesive has come in contact with the panel is likely to deform or tear the gasket.This may result in an improper seal. For best results, follow these directions:

1. Stand the Ambassador counter on a desk or table with its display down, screw terminals up.

2. Remove and discard the center square of the gasket at the scribe marks in the gasket and paper backing. Do not remove the backing from the remaining outer rim.

3. Slide the gasket down the unit until it is in position at the rear of the unit's front bezel. The paper backing side should be up.

4. Insert the tip of a knife between the paper and the gasket and, while holding the gasket down to the unit with the knife, peel off the paper backing.

5. Slide the unit through the panel cutout until the gasket firmly adheres to the panel.

6. Install the mounting clips and screws as shown in the diagram on page 37. Do not overtighten the mounting screws. The screws should be tight enough to firmly hold the unit in place, but not so tight as to squeeze the gasket out from behind the front bezel.

7. A switch shall be included in the building installation:

• It shall be in close proximity to the equipment and

within easy reach of the operator.

• It shall be marked as the disconnecting device for the

equipment.

• Switches and circuit breakers in Europe must comply

with IEC 947.
