7. CONTROLLER INPUTS AND OUTPUTS
7.1. Main Measuring Inputs
The main input is the source of measured value taking part in
control and alarms.
The main input is an universal input, to which one can connect
different types of sensors or standard signals. The selection of the input
signal type is made by the parameter iNty.
The position of the decimal point which defi nes the display for-
mat of the measured and the set point value is set by the parameter dp.
For linear inputs, one must set the indication for the lower and upper
analog input threshold iNlo and iNHi. The correction of the mea-
sured value indication is carried out by the parameter shif.
7.2. Additional Measuring Inputs
The additional input can be the source of remote set point
value (sPmd set on in2) or the signal for retransmission (aofn set on
pv2).
The additional input is a linear input. The selection of the input
signal type is possible between 0…20 mA and 4…20 mA by the para-
meter i#ty. The position of decimal point which defi nes the display
format of the measured and set point value is set by the parameter dp2.
One must also set the indication for the lower and upper analog input
threshold i#lo and i#Hi.
The signal from the additional input is displayed with the cha-
racter „d” on the fi rst position. To display the value, one must press
the
push-button till the moment of its appearance on the lower
