2 I/O Port The I/O part allows communication with external equipment via analog data (programmable logic control - PLC). Through this connection some functions of the Ecotec E3000 can be controlled externally or measurement data or the Ecotec E3000 status may be communicated to external equipment. Through relay changeover contacts the trigger levels as well as the operating mode (Ready) of the Ecotec E3000 may be monitored. 2.1 Connecting the I/O Port Hazardous voltage.

Change from high to low to deactivate (wake up).
Gas select, gas a, gas b Through the control inputs Gas … (pin 9, 13 and 25) it is possible to select a gas loaded in the active gas memory (one gas out of four). The Ecotec E3000 will then operate in the single gas mode. With an edge triggered signal from LOW to HIGH at Pin 25, the selected gas at Pin 13 and 9 becomes valid. Table 2: Gas select 2.1.
Technical Data relay outputs Material damage if load is high. Wrong input voltage or current can destroy the unit. ► Pay attention to the technical data of the relay outputs: Maximum load rating is 60 V DC / 25 V AC and 1 A per relay (resistive load). Relay output Active = Normally open contact (NO) closed Trigger If the preset trigger level is exceeded, relay contact NO will close and the relay contact NC will open respectively.
LOG The voltage range spans from 0 V to 10 V. Beginning at 1 V, each leak rate decade is spread over 2 V, i.e.: 1.0 … < 3 V: 1st decade 3.0 … < 5 V: 2nd decade 5.0 … < 7 V: 3rd decade 7.0 … < 9 V: 4th decade Thus a leak rate range of 4 decades will be output by way of an analogue signal. The four decades are set through the value and the unit of measurement for the trigger level.
Recorder output gas Here one gas from the four gases is defined which will be output as the analog signal through channel 1. Selecting one of the numbers 1 … 4 outputs the corresponding gas 1 … 4 on the display as the analog signal. Channel 2 (pin 14 of the I/O port) indicates the gas number by way of a voltage, i.e. a voltage between 1 … 4 V will be present accordingly.

Leak rate Cal (Input) Ready (Output) Cal stable (Output) Measurement helium Measurement air Fig. 5: Calibration timing interval A calibration process is started by setting the calibration input to HIGH after the sniffer probe tip has been placed in front of a test leak. The ready signal will go to HIGH after the calibration process has started. If a calibration is started within the first 20 min after power on a warning is issued.
3 RS-232 interface The Ecotec E3000 is equipped with a RS-232 interface which is located on the rear right side of the instrument. This interface is of the DCE type (Data Communications Equipment) and allows the connection of a PC for monitoring and data logging. The connection is provided through a commercially available Sub-D plug. The RS-232 protocol can be set to “ASCII”, “Diagnostics”, “Printer auto” or “Printer manual”.
3.2 Interface Commands 3.2.1 Command Format In ASCII mode any command starts with « * (ASCII code 42 dec)» and is finished with the end sign selected (e.g. CR). There is no differentiation between upper and lower case (exception: gas names and names of I•Guide programs). A blank is required between the command and the parameter, no other blanks are allowed (except names of I•Guide programs). There is a short and an extended form of the command.

3.2.3 Error Messages The following error messages may be received from the Ecotec E3000: Table 12: Error messages 3.
Diagnostics The diagnostics protocol is a binary protocol used for analysis in quality control and trouble shooting during manufacturing and service. Default setting: ASCII Printer manual The Printer manual protocol allows to send leak rates on pressing the right sniffer probe button. One line will be send for each currently enabled gas. When in any of the two printer modes, no ASCII commands must be sent to the Ecotec E3000 as this will interrupt the printer mode.
