PRODUCT SPECIFICATION

Please refer to the product data sheet for full specification, available to down load at www.status.co.uk.

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

but the computer used must be isolated from the mains supply earth to avoid ground loop effects.

Device

M-CONFIG or USB_LINK software

COMPUTER

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

Supply

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).

METHOD

1.0 Connect transmitter to a suitable input simulator or sensor.

Connect supply, connecting a digital meter to monitor output.

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.

When the trim menu is open the range LED will flash :-

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.

METHOD

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

ration 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).

3.0 Once the menu has been entered, quickly (within 1 second)

apply a single press the the raise(high) lower(low) button to store

setting.

To abort configuration, allow configuration to time out by not

pressing buttons for 5 seconds.

OUTPUT DAMPING

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.
