be in the "configuration mode". While in this mode, the control display
will show the values of various configuration settings. The first setting to
be displayed is the "U1" setting. See setting summary. By using the in-
crease " ", decrease " " buttons, it is possible to scroll through the list
of settings to those needing modification.
To adjust a setting while in the "Configuration Mode", use the increase
" ", decrease " " buttons to bring the particular setting into the view
on the display. Press the "SET" button to change the value of the set-
ting. Once the "SET" button has been released, the display will flash.
Use the increase " ", decrease " " buttons to scroll through the op-
tions for the selected setting. After the option has been determined, press
the "SET" button once more to lock the new value into memory.
After completing all changes to the configuration of the control, the
new configuration must be saved. To save the new value, press the
increase " " and decrease " " buttons simultaneously. This will cause
the control to store the new values internally and then reset the unit.
Note: Switching off power to the unit before saving the new configura-
tion will cause all changes to be lost.

Note: The 5447 sensor board will also accept 2 wire RTDs. The default
sensor type setting is "1" (1000 ohm 2 wire RTD). When using the
5447 sensor board, an "on-board" DIP switch must also be config-
ured, see page 30.
* An optional 5416 sensor board will permit transmission of the pro-
cess value as a 4-20 mA signal.
** An optional 5419 sensor board will permit transmission of the pro-
cess value as 4-20 mA signal.
U2, Signal Offset
This setting, which may be any number from -9 to +9, represents an offset
value which is applied to the signal received from the sensor. The units
(ºC, ºF, ohms, etc.) will be dictated by the type of sensor selected in "U1"
settings.
