The SELECT ATTRIBUTE page for each setpoint allows the user to pick which attribute(s) to program. Pressing
SETPOINT will bring up a number pad screen via which a numerical value can be given to the setpoint.
Pressing the SP TYPE button repeatedly causes the setpoint type to toggle between “valve” and “pressure” – in
other words choosing a “valve” type here means that the setpoint, when activated, will drive the valve to a prescribed
position as opposed to controlling to a particular pressure.
SET GAIN, SET PHASE and SET KAP are also functions that will bring up a number pad by which the value can be
changed. However, the user is advised that these parameters do not normally need to be adjusted beyond the fac-
tory settings, because the controller contains an advanced adaptive pressure control algorithm that will work well
under most conditions.
In all cases are the current values for SETPOINT, etc. displayed above each button. Pressing BACK or EXIT from the
SELECT ATTRIBUTE page automatically stores the SP TYPE entry in NVRAM.
The number pad, in this case shown for the “setpoint 1” value entry provides the necessary interface to key in the
desired numerical entry. Be sure to pay attention to the MIN and MAX values, as these limits provide the lower and
upper range for the value in question. Pressing SET VALUE at the end saves the information to NVRAM. Pressing
EXIT without pressing SET VALUE will return the user to the MAIN MENU without saving the entered information.
