This guide will help you to replace the ACH550 drive with the

ACH580 HVAC drive. Follow the steps outlined in this guide to

find the optimal replacement product and to expedite the

replacement process.

Step 1: Sizing of the drive and selecting options

Compare power range, mounting methods and dimensions to

select the appropriate ACH580 product compared to the

ACH550 drive, see the checklist items for some useful

guidance.

Step 2: Wiring and parameter setup

Compare electrical data and basic parameter range for optimal

replacement. Use the replacement ACH580 manual to assist

with the commissioning process.

Before beginning, some basic checklist items

All information regarding the control of your application

should be gathered from the ACH550 prior to selecting and

performing the actual replacement, control and parameter

settings should be noted to ensure consistency in the

replacement ACH580.

This checklist covers the main information you may require to

guide you through the replacement process. If the ACH550

cannot be powered, the technician should gather all the

information below that is not parameter related.

Using the comparison guide

The AI825 Analog Input Module has 4 individualy galvanic isolated,

bipolar current/voltage inputs. Each channel can be either a voltage

or current input.

The module has a direct current input that withstand up to 6.3 V and

a over voltage protected current input that withstand up to +30 V d.c.

The current is limited by a PTC resistor.

Power to the input stages is converted from the 24 V on the

ModuleBus.

The AO815 Analog Output Module has 8 unipolar analog output

channels. The module performs self-diagnostic cyclicaly. Module

diagnostics include:

• External Channel Error is reported (only reported on active

channels) if the process power supply that supply voltage to

output circuitry is too low, or the output current is less than the

output set value and the output set value is greater than 1 mA

(open circuit).

• Internal Channel Error is reported if the output circuit can not

give the right current value.

• Module Error is reported in case of Output Transistor Error, Short

Circuit, Checksum Error, Internal Power Supply Error or

Watchdog error.

The module has HART pass-through functionality. Only point to point

communication is supported. The output filter must be enabled on

channels used for HART communication.

KPM KB2 with +24 VDC + power supply

Relays are of dry contact types. In normal operation the “Break Out On” relay is open and it closes

during a break. In case the power is lost or turned off the “Break Out On” relay remains open

(disabled). “Break Out Off” works in the opposite way. There is 2 parallel Break Relays, Break Out

1 and Break out 2 which are working simultaneously.

”Alarm Out Off” is normally closed. It opens in case the built-in self-diagnostics detects a failure.

If power is lost or turned off the “Alarm Out Off” is OPEN. “Alarm Out On” works in the opposite

way. There is 2 parallel Alarm Relays, Alarm Out 1 and Alarm out 2 which are working

simultaneously.

Fiber optic cable is connected to the optics block. It does not matter which one of the two cables

is connected to the receiver inlet (Rx). In a normal application another cable is connected to the

RGB light source. IR light source is used in special cases such as heavy steam environment or in

an application where exceptionally strong light is needed.

Operating principle

The KPM KB2 operates on a proven, non-contact reflection principle. The light source can be

either RGB LED (red, green, blue) or IR LED (infrared). The optical sensor is placed above or under

the web. Applications include paper or board webs, wires or felts. Thanks to the unique RGB

detection method the color of the product or the felt has no effect on the measurement

reliability. The sensor is neither affected by dirt, steam nor temperatures up to 180 °C (356 °F)

when installed according to ABB Oy, KPM specifications. There are no electronic components

located in the sensor head.

The optical sensor is connected through a fiber optic cable to the RGB/IR light source located in

the display unit. The RGB/IR LEDs emit pulsed red, green, blue, or IR light onto the web surface.

The reflected light is received and transmitted through the fiber optic cable to the detector. All

light components are analyzed fast for a reliable break detection.

A break activates a relay, which can be connected to the logic control of a paper machine. The

reflected light intensities are also available as optional 4 – 20 mA analog outputs.

The self-cleaning sensor head is a 33.7 x 1500 mm (1″ x 59″) stainless steel tube with two holes

serving as eyelets for the fiber optics and outlets for purge air. Continuous airflow through the

stainless steel enclosure keeps positive pressure around the sensor head’s eyes and keeps the

eyelets free of steam, dust or debris. The openings should be located towards the surface being

monitored.

System components

KPM KB2 fiber optic sheet break detection system contains:

 Sensor head installed above or under the web.

 Fiber optic cable protected with a flexible conduit.

 Display unit housing the light source, detector, and the measurement computer.

KPM KB2 is a solution to high temperature sheet break applications. The light source, detector,

and electronics are isolated from the high temperature environment by a 6 m (20′), 9 m (30′) or

12 m (40′) fiber optic cable. While the sensor head is exposed to high temperatures, the

electronics is mounted in a less hostile environment.

Sensor head “eye” holes are kept clean by purging instrument air through the sensor housing.

Flowing air keeps the eyelet holes clean and prevents dirt or steam from contaminating the

active optic surfaces. Purging air helps also to keep the sensor head temperature lower in high

temperature applications.

KPM KB2 requires clean instrument air at 0.5 – 3.0 bar (7 – 40 psi), the rotameter or pressure

regulator can be used for the easy detection of airflow.

Plug-and-Produce Expanded Control

An advanced function card provides an additional two current

outputs and two further alarm relays that can be assigned to

either measured values or sample temperature.

ABB Plug-and-Produce software automatically reconfigures the

analyzer if an option board is added later. No user programming

is necessary.

A real-time clock and logbook are also included, making the

full-facility versions extremely powerful and versatile.

Significantly Reduced Maintenance Costs

The AX400 Analyzers are supplied as standard for 85 to

265VAC operation. There are no inner switches to set.

They can also be provided for 24V AC or 12 to 30V DC supply

and recognize automatically which of the two supplies is being

used. 24V DC operation reduces maintenance costs

significantly by negating the need for costly, yearly safety tests to

ensure compliance with safety procedures.
