tages. Ignoring this warning can result in severe personal injury or mechanical damage. To avoid the risk of electric shock and fire, the safety instruc tions of this manual must be observed and the guidelines fol lowed. The specifications must not be exceeded, and the device must only be applied as described in the following. Prior to the commissioning of the device, this manual must be examined carefully. Only qualified personnel (technicians) should install this device. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
Until the device is fixed, do not connect hazardous voltages to the device. The following operations should only be carried out on a discon-

nected device and under ESD safe conditions: General mounting, connection and disconnection of wires. Troubleshooting the device.
Repair of the device must be done by Red Lion Controls only.
WARNING
WARNING
INSTAL­LATION
The device must be mounted on a DIN rail according to DIN 46277.
WARNING
Do not open the front plate of the device as this will cause damage to the connector for the display / programming front PGM. This device contains no DIP-switches or jumpers.

SYMBOL IDENTIFICATION

Triangle with an exclamation mark: Warning / demand. Potentially lethal situations.
The CE mark proves the compliance of the device with the essential requirements of the directives.
The double insulation symbol shows that the device is protected by double or reinforced insulation.

SAFETY INSTRUCTIONS

DEFINITIONS Hazardous voltages have been defined as the ranges: 75 to 1500 Volt DC, and
50 to 1000 Volt AC. Technicians are qualified persons educated or trained to mount, operate, and also troubleshoot technically correct and in accordance with safety regulations. Operators, being familiar with the contents of this manual, adjust and operate the knobs or potentiometers during normal operation.
RECEIPT AND UNPACKING:
Unpack the device without damaging it. The packing should always follow the device until this has been permanently mounted. Check at the receipt of the device whether the type corresponds to the one ordered.
ENVIRONMENT
Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock, as well as rain and heavy moisture. If necessary, heating in excess of the stated limits for ambient temperatures should be avoided by way of ventilation. All devices fall under Installation Category II, Pollution Degree 1, and Insulation Class II.
MOUNTING
Only technicians who are familiar with the technical terms, warnings, and instruc­tions in the manual and who are able to follow these should connect the device. Should there be any doubt as to the correct handling of the device, please contact your local distributor or, alternatively,
Red Lion Controls
LP1102 5
Mounting and connection of the device should comply with national legislation for mounting of electric materials, i.a. wire cross section, protective fuse, and location. Descriptions of input / output and supply connections are shown in the block diagram and side label.
The following apply to fixed hazardous voltages-connected devices:
The max. size of the protective fuse is 10 A and, together with a power switch, it should be easily accessible and close to the device. The power switch should be marked with a label indicating that it will switch off the volt age to the device.
Year of manufacture can be taken from the first two digits in the serial number.
UL INSTALLATION REQUIREMENTS
Use 60/75°C copper conducters only. For use only in pollution degree 2 or better.
Max. ambient temperature ............................ 60°C
Max. wire size ...................................................... AWG 26-14
UL file number .................................................... E324843
CALIBRATION AND ADJUSTMENT
During calibration and adjustment, the measuring and connection of external voltages must be carried out according to the specifications of this manual. The technician must use tools and instruments that are safe to use.
NORMAL OPERATION
Operators are only allowed to adjust and operate devices that are safely fixed in panels, etc., thus avoiding the danger of personal injury and damage. This means there is no electrical shock hazard, and the device is easily accessible.
CLEANING
When disconnected, the device may be cleaned with a cloth moistened with dis­tilled water.
LIABILITY
To the extent that the instructions in this manual are not strictly observed, the custom er cannot advance a demand against Red Lion Controls that would otherwise exist according to the concluded sales agreement.

HOW TO DISMANTLE THE DEVICE

First, remember to demount the connectors with hazardous voltages.
Picture 1:
Detach the device from the DIN rail by lifting the bottom lock.

UNIVERSAL I/f CONVERTER
AFCM
• Input for RTD, TC, Ohm, potentiometer, mA and V
• Frequency output NPN, PNP and TTL
• Generates frequencies from 0.001...25000 Hz
• 2-wire supply > 16 V
• Universal AC or DC supply

Advanced features

• Programmable by way of detachable display front (PGM), process calibration, signal simulation, password protection, error diagnostics and help text available in several languages.

Application

• Linearised, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a frequency signal, e.g. from solenoids and butterfly valves or linear movements with attached potentiometer.
• Power supply and signal isolator for 2-wire transmitters.
• Process control by way of a frequency signal transmitted to e.g. a PLC or a process computer.
• Galvanic separation and conversion of analogue signals to frequency signals.

Technical characteristics

• When AFCM is used in combination with the PGM display / programmer front, all operational parameters can be modified to suit any application. As the AFCM is designed with electronic hardware switches, it is not necessary to open the device for setting of DIP-switches.
• A green front LED indicates normal operation.
• Continuous check of vital stored data for safety reasons.
• 3-port 2.3 kVAC galvanic isolation.

PGM DISPLAY / PROGRAMMER FRONT

• PGMMOD00 - Programming Module
• PGMMODC1 - Program/Comms Module
Functionality
The simple and easily understandable menu structure and the explanatory help texts guide you effortless ly and automatically through the configuration steps, thus making the product very easy to use. Functions and configuration options are described in the section ”Configuration / operating the function keys”.
PGMMOD00
Application
• Communications interface for modification of operational parameters in AFCM.
• Can be moved from one AFCM device to another and download the configuration of the first converter to subsequent converters.
• Fixed display for readout of process data and status.
Technical characteristics
• LCD display with 4 lines; line 1 (H = 5.57 mm) shows input signal, line 2 (H = 3.33 mm) shows units. Line 3 alternates between digital output value and scaling (kHz, Hz, mHz, P/m, P/h, P/d) or shows TAG no. Line 4 shows tendency readout for the input signal and communication status.
• Programming access can be blocked by assigning a password. The password is saved in the converter in order to ensure a high degree of protection against unauthorised modifications to the configuration.
Mounting / installation
• Click PGM onto the front of AFCM.
