Event Input - Brainchild P41 User Manual

How to use INLO and INHI : How to use INLO and INHI :
If 4 - 20 mA is selected for INPT,let SL specifies the input signal low (
ie. 4 mA ), SH specifies the input signal high ( ie. 20 mA ), S specifies
the current input signal value, the conversion curve of the process
value is shown as follows :

Formula : PV = INLO + ( INHI INLO ) Formula : PV = INLO + ( INHI INLO )
Example : A 4-20 mA current loop pressure transducer with range Example : A 4-20 mA current loop pressure transducer with range
0 - 15 kg/cm is connected to input, then perform the 0 - 15 kg/cm is connected to input, then perform the
following setup : following setup :
INPT = 4 - 20 INPT = 4 - 20
INHI = 15.00 INHI = 15.00

3-3 Event Input

3-3 Event Input
The Event input accepts a digital type signal via momentary and close
contacts. The types of signal :
(1) relay or switch contacts, (2) open collector pull low and (3) TTL
logic level, can be used to switch the event input. one of eight functions
can be chosen by using
0 NONE : Event input no function
1 RUN : Applicable when unit is in static mode or Off mode
Requires only momentary type input
Event input close: unit will enter run mode
