function:
If the input signal exceeds the top measuring range set,output current 22mA(or
output voltage 5.5V), the relay aets as the input, SPH LED ON, faceplate display “full”.
If the input signal fallen below the measuring range set, output current 3mA (or
output voltage 0.75V), the relay aets as the input, SPL LED ON, faceplate display
“nfull”.
If the input signal fault and input signal can’t transmission,output current2mA(or
output voltage 0.5V),the relay aets as the input, SPH.SPL ON,faceplate display “no in”.
input signal model is: in2.H/in2.r:
If the input loop-current I
<
0.1mA, proximity switch alarm(break line), output current
2mA,the relay aets as the input,SPH.SPL LED ON, faceplate display “inopn”.
If the input loop-current I
>
6mA, proximity switch alarm(shout circuit)output current
2mA, the relay aets as the input, SPH.SPL LED ON, faceplate display “insot”.
Note: If input signal top limit overflows or lower limit overflows or input signal
faults, the output current can be configured to any value of 0~24mA (0~6V for
voltage) separately.
Start delay time: 0~9999s
When the output relay is set to alarm
mode
with
under-speed, the
instrument
will not output an alarm signal during the launch delay time after power on due to the
under speed of input signal
.

The input signal pattern choice:
in H:Frequency input for NAMUR(2

Not: If users need to switch measurement display unit, (Hz or min ), you need to
set measuring range

The LED indicator light instructions:
SPH: If the input signal exceeds the top alarm(contains dead band) LED ON.
SPL: If input signal fallen below the alarm(contains dead band) LED ON.
