· Re-transmit output SPan “rt.SP’ (default value: programmed display span value)
When the display indicates this value PLUS the offset value (“rt.SP’+”rt.OS”), 20mA is transmitted. (see notes).
· Reset “RESt”
By selecting this setting, the device is reset to the factory defaults press “
S
”& “
T
” or “+” & “-” together to select.
DUAL DISPLAY DEVICE PROGRAMMING Example 1:
Set the device to de-energise relay 1 when the voltage is below 10.0V and above 90.0V
If all of the following settings are NOT available, exit the menu and activate the advanced menu.
Press “
4
” to display “Hi 1”.
Use “
T
” and “
S
” buttons to change the value to “90.0”.
Press “
4
” to display “Lo 1”.
Use “
T
” and “
S
” buttons to change the value to “10.0”.
Press and hold “
4
” for 3 seconds to exit the menu.
DUAL DISPLAY DEVICE PROGRAMMING Example 2:
Set the device to display 0-100% for a voltage of 0-50V
ie: 0V=0%, 50V=100%
If all of the following settings are NOT available, exit the menu and activate the advanced menu.
Press “
4
” repeatedly until “SCAL” is displayed.
Use “
T
” and “
S
” buttons to change the value to “3000”.(ignore decimal pointer)
150V (full scale voltage) / 50V ( new full scale value) x 100 (display value at new full scale value value)
Press “
4
” to display “dEci”.
Use “
T
” and “
S
” buttons to move the decimal pointer to the desired position.
SINGLE DISPLAY DEVICE PROGRAMMING Example 1:
Set the device to de-energise relay 1 when the voltage
is below 10.0V and above 140.0V
If all of the following settings are NOT available, exit the menu and activate the advanced menu.
Press “MENU” to display “Hi 1”.
Press “SELECT” and change the value to “140.0”.
Press “ENTER”. “Lo 1” is displayed.
Press “SELECT” and change the value to “10.0”.
Press “ENTER”.
Press “BACK” to exit the menu.
SINGLE DISPLAY DEVICE PROGRAMMING Example 1: Set the device to display 0-100% for a voltage of 0-50V
ie: 0V=0%, 50V=100%
Press “MENU” repeatedly until “SCAL” is displayed.
Change the value to 3000.
150V (full scale voltage) / 50V ( new full scale value) x 100 (display value at new full scale value value)
Notes:
· Whenever the input signal is above or below the “CAL.O” or “CAL.S” values by more than 3%. The display indicates “Er.Hi” or “ER.Lo”.
· Certain settings are reset to default when the device is re-configured. Re-check all settings to ensure they are correct before
commissioning. (use the advanced menu)
· The maximum & minimum values are NOT updated during the first 30 seconds after power up. This allows the input signal to
stabilize first.
