RECEIVE AND UNPACKING

Please inspect the packaging and instrument thoroughly for any signs of transit damage. If the instrument has been damaged, please notify your supplier
immediately.

CONFIGURATION

IMPORTANT During configuration the device takes its power from the USB port, therefore no power connection is required. The device can be configured while powered

M-CONFIG or USB_LINK software

(usb_link V2.0 or greater)

The following parameter can be configured by simply entering as prompted by the software package.

· Input type / input sensor / units(temperature inputs) / sample rate

· Scale input to process variable (process inputs only)

· Analog Output / Set Type voltage or current / scale output signal range / scale output to process
Set adjustable damping for both rising and falling output. Set correction for voltage output load.

· Trip Outputs / Set action / Set setpoints / Set deadband / Set adjustable delay on and delay off

· Set burnout direction on sensor failure or input overrange.

· Set the function of the front panel user buttons to off, trim or configure.

User trim function allows manual adjustment of the analog output, this is useful for minor calibration adjustment or
trimming out any sensor error, ± 5 % of range adjustment is available at both offset and span. Raise and lower buttons
are provided on the front panel of the transmitter, accessed using a 3 mm flat blade screw driver. Insert the screw
driver into the appropriate slot to operate the button. The button has a click action.

The transmitter will automatically detect the correct trim point (offset or span) based on the output signal. Offset will be
trimmed when the current in the offset band, span when the current is in the span band. No trim action occurs at any
other current. Note this function needs to be selected by the software configuration tool before use. To lock settings
after adjustment the operator can again use the tool to turn this function off, (select the option to save trim when
downloading configuration).

USER RANGE CONFIGURATION

This function allows two point manual configuration of the re-transmission current (voltage) at low and high range against a live input
signal. This is useful for on-site configuration, example with a slide wire input the user manually position the slide at both low and high
position and configures the unit to operate over this range. Configuration is achieved using either the raise (span) or lower (offset)
buttons.
To operate this function it must first be selected using the software configuration tool. The operator may lock this function (once set) by
turning off the function.

1.0 Connect transmitter to a suitable input simulator or sensor. Connect supply, turn supply on, set input to either offset or span calib­ration point.

2.0 To enter configuration, set input to desired high or low
setting and wait 10 seconds. Press and hold raise(high) or
lower(low) button on for 2 seconds to enter.

The Ok LED will then start to flash at a slow rate (low) or fast
rate(high).

Turn supply on, set input to offset/span calibration point.
IMPORTANT - IF PERFORMING TWO POINT CAL, ALWAYS CAL
OFFSET FIRST.

2.0 Enter trim menu by pressing "raise" button for two seconds.

User adjustable damping of the analog output is provided for both rising and falling signal. The adjustable range is (0 to 250) second for a ( 0 to 20) mA or
(0 to 10) V swing. To calculate rate of change of output signal divide 20mA (10 V) by damping setting, example if damping is set to 100 seconds the mA
output will change at a rate of (20/100) = 0.2 mA /Second. Use USB_LINK software to configure damping setting.

TRIP OUTPUTS

Dual trip SPDT relays are available. The contacts are rated at 240 V ac 1 A (Non inductive) 30 V DC 1 A. An external snubber network is recommended when
switching inductive circuits. Please ensure the snubber network is rated for the application. Four actions are provided, as detailed in the diagram below.
The Alarm actions may also be used for inverted control applications, example the high alarm action can be used to control a cooling fan when used to
control the temperature of a heat source. Ajustable setpoint and deadband are provided together with adjustable on and off delays for each trip. The
delay range is ( 0 to 250 ) Seconds.
