Analog Output Voltage proportional to Pressure (WIN 111=3)
FAULT
: this open collector output signal is ON when a system
fault condition is detected.
PROGRAMMABLE SET POINT
: this open collector output
signal is enabled when the reference quantity chosen (fre-
quency, power or time or pressure or normal) is higher than
the set threshold. The signal can be "high level active" (i.e. the
output is normally OFF and changes to ON when activated), or
"low level active" (i.e. the output is normally ON and changes
to OFF when activated). Moreover, if the reference quantity is
the frequency or the power or pressure drawn, it is possible to
set the hysteresis (in % of the threshold value) to avoid re-
bound
For example:
- reference quantity: frequency
-
threshold: 867 Hz
- hysteresis: 2%
- activation type: "high level"
It is possible to delay the set point checking for a programma-
ble delay time.
The PROGRAMMABLE SET POINT signal has the following
default settings:
- reference quantity: frequency
- threshold: 867 Hz
- hysteresis: 2%
- activation type: high level
- delay time: 0 second
NOTE
The T-Plus (optional) allows the operator to set all the pro-
grammable features.
