(a) UNPACKING THE I/O SIGNAL CONDITIONER a.1 Inspect Package for External Damage Your I/O Signal Conditioner was carefully packed in a sturdy cardboard carton, with anti-static cushioning materials to withstand shipping shock. Upon receipt, inspect the package for possible external damage. In case of external damage to the package contact the shipping company immediately. a.2 Unpack the I/O Signal Conditioner Open the carton carefully from the top and inspect for any sign of concealed shipping damage.
(b) DESCRIPTION This Signal Conditioner allows analog voltage levels to be set and read via its RS-232 serial port. Commands are provided to perform various functions: an analog output, read an analog input, verify the communications link, programming, and enter calibration mode. (c) FEATURES The I/O is capable of operating in a voltage output mode or a current output mode. When operating in the voltage mode the analog input and output range is 0.00 to 5.00 volts.
d.2 CE Compliance Any model I/O Signal Conditioner bearing a CE marking on it, is in compliance with the below stated test standards currently accepted. EMC Compliance with 89/336/EEC as amended; Emission Standard: EN 55011:1991, Group 1, Class B Immunity Standard: EN 55082 1:1992 Environmental (per IEC 664): Installation Level II; Pollution Degree II (e) ELECTRICAL CONNECTIONS e.1 Connector Pin Assignments All connections are made at connector J1. This is a pinch type connector.
CAUTION: Make sure power is OFF when connecting or disconnecting any cables in the system. The power input is protected by a 1A re-settable fuse. If a shorting condition or polarity reversal occurs, the fuse will cut power to the flow transducer circuit. Disconnect the power to the unit, remove the faulty condition, and reconnect the power. The fuse will reset once the faulty condition has been removed. e.
RS485 APPLICATION: Make sure RS485 Terminal Equipment (RS-485 to RS232 Converter) is configured for bidirectional Multi drops Two-Wire Half-Duplex operation (TX+ is connected to RX+ and TX- is connected to RX-). Connect the unit TX(-) line (pin 5) to the terminal TX- line, connect the unit RX+ line (pin 6) to the terminal TX+ line. Connect the I/O GND (pin 8) to terminal GND (if applicable). To program the module remove power from the unit and install the shorting plug on jumper JP1 between pins 2 and 3.
(h) SELECTING THE MODE OF OPERATION Before operating in the desired mode the I/O has to be calibrated in the same mode. To set the unit to operate in 0 - 5V mode install shorting plugs between pins 1 and 2 on JP2, JP3, JP4 and, JP5. If 4 - 20mA current mode is desired install the shorting plugs between pins 2 and 3 on JP2, JP3, JP4 and, JP5. See Jumper Definitions for more detail. (i) COMMANDS The following is a list of the valid commands, command format and, unit response.
make the response easier to read. If a crc is not required it is not sent in the response line. Responses sent by the I/O Module are preceded with a start character symbol, #. All responses are terminated with a CR. Only the number of data bytes required by the response are sent. Leading zeroes are stripped. Host S Command: S or s - This command queries the I/O Module for its communication status. If the communications line is intact the I/O Module responds to the host with an “OK”.
Host R Command: R or r - This command tells the I/O Module to receive a new set point. Four characters must be sent and one of these characters is always a decimal point. If the set point does not fill all four characters trailing zeroes are added. A crc is added if error checking is enabled, otherwise it is not sent. If the command is not recognized “Bad Command” is returned. An example of a valid command to a unit with address >: > > R 1.00 crc CR > > r 1.
(j) TROUBLE SHOOTING Your I/O Signal Conditioner was thoroughly checked at numerous quality control points during and after manufacturing and assembly operations. It was calibrated in accordance to conditions for a given. It was carefully packed to prevent damage during shipment.
