Menu 17 – Set switch-off delay for S1 output
Set the switch-off delay value for the S1 output. (0 – 100 sec).
Menu 18 – Set switch-on delay for S2 output
Set the switch-on delay value for the S2 output. (0 – 100 sec).
Menu 19 – Set switch-off delay for S2 output
Set the switch-off delay value for the S2 output. (0 – 100 sec).
Menu 20 and Menu 21 – Maximum / minimum pressure display
& Displays the high pressure (HiPr) or low pressure
(LoPr) value during the measurement process (values are lost when power is
gone). To delete the values, press the two buttons at the same time again
within 1 second.
Menu 22 – Measured value update (display)
Sets the display refresh cycle length (0.0–10 sec).
Menu 23 – Simulate contact output S1
The state of switch output S1 can be simulated. Select activate or
deactivate with the up and down buttons (output S1, tES1).
Menu 24 – Simulate contact output S2
The state of switch output S2 can be simulated. Select activate or
deactivate with the up and down buttons (output S2, tES2).
Menu 25 – Simulate analogue output
The value of the analog output signal can be simulated. Select one
of the following settings: “oi 4” (4 mA or 2 V), “oi12” (12 mA or 6 V) and ”oi20”
(20 mA or 10 V)
Menu 26 – Signal choosing for analogue output
Assigning the desired input signal to the analog output; if “P1” or
“P2” is selected, the analog output follows the static pressure on the suitable
input. By the setting “DIFA”, “DIFB” and “DIFC” the analog output follows the
calculated difference pressure from P1 and P2. With "DIFB," the analog signal
is offset, in addition, about 50% FSO upwards; with “DIFC” the square root of
the differential signal is displayed.
Menu 27 – Error signal definition
Set the desired error signal (this is sent out if there is an error).
Permitted options: “0FF” (no error signal), “C 0” (0 mA or 0 V), “C L0” (3.5 mA
or 1.75 V) and “C HI” (23 mA or 11.5 V). The error message appears only
when Menu 6 “HILo” is set to “on.”
Menu 28 – Offset compensation / position correction
A position correction or an offset's comparison can be carried out
only with an available appropriate reference source, in so far as the measuring
value deviation lies within certain borders; confirm the menu point "P0SI" by
pressing both buttons. If the offset deviates from the environment pressure, it
is necessary to connect the pressure reference, which corresponds to the
measuring start value in P1. P2 must stay open! If both keys are pressed again
afterwards, the signal topically spent by the differential pressure transmitter
will be stored as an offset. The display shows the adjusted zero point value,
although the sensor signal is offset.
Note that with an available analog output, this remains unaffected by the
change. Furthermore, offsetting shifts the full scale as well.
