Danfoss vlt FC 102 Programming Guide

30-96 Port
Range: Function:
5001* [1024 -
65535 ]
Enter the TCP port to connect to.
30-97 Wi Timeout Action
Select which action to execute if a local reference (hand-on
mode) or a remote reference (auto-on mode) is set via the
wireless connection and the connection is lost.
Option: Function:
[0] * Do Nothing The frequency converter does not
do any extra actions.
[1] Stop Motor The frequency converter stops the
motor (if the motor was started via
a wireless connection).
3.26 Parameters: 31-** Pressure Sensor/
BypassOption
3.26.1 Parameters 31-** Bypass Option
Parameter group for the conguration of the electronically
controlled bypass option board, VLT® Bypass Option MCO
104.
31-00 Bypass Mode
Option: Function:
[0] * Drive Select the operating mode of the
bypass: The frequency converter
operates the motor.
[1] Bypass The motor can be run at full speed
in bypass mode.
31-01 Bypass Start Time Delay
Range: Function:
30 s* [0 - 60 s] Set the time delay within the time
when the bypass receives a run
command and the time when it
starts the motor at full speed. A
countdown timer shows the time
left.
31-02 Bypass Trip Time Delay
Range: Function:
0 s* [0 - 300 s] Set the time delay within the time
that the frequency converter
experiences an alarm that stops it
and the time when the motor is
automatically switched to bypass
control. If the time delay is set to 0,
a frequency converter alarm does
not automatically switch the motor
to bypass control.
31-03 Test Mode Activation
Option: Function:
[0] * Disabled Test mode is disabled.
[1] Enabled The motor runs in bypass, while the
frequency converter can be tested
in an open circuit. In this mode, the
LCP does not control start/stop of
the bypass.
31-10 Bypass Status Word
Range: Function:
0* [0 - 65535 ] Views the status of the bypass as a
hexadecimal value.
31-11 Bypass Running Hours
Range: Function:
0 h* [0 -
2147483647 h]
Views the number of hours in
which the motor has run in bypass
mode. The counter can be reset in
parameter 15-07 Reset Running
Hours Counter. The value is saved,
when the frequency converter is
turned o.
31-19 Remote Bypass Activation
Option: Function:
[0] * Disabled
[1] Enabled
3.26.2 31-** Pressure Sensor
The pressure transmitter unit sensors are calibrated from
factory to ensure correct pressure measurement from the
1
st
power up. It delivers pressure values on the LCP, analog
output or eldbus interface without any further sensor
calibrations. It also has an internal pressure compensation
measurement to adjust for absolute pressure measurement.
Each pressure sensor has a -/+ measuring input to enable
a selection of absolute or dierential pressure signal,
related to the way the inputs are mechanically connected
in the application.
The pressure transmitter unit has built-in functions to
monitor air
lters and general pressure level. Each sensor
input has its own individual trigger levels when pressure
level drops below or above the dened threshold values.
Users can dene the time window after which users are
notied about the pressure trigger status change. This
status can be manually or automatically reset, as soon as
the pressure conditions return outside the trigger levels.
The pressure status information can be used in dierent
ways, as warnings and alarms or as part of the process
control via SLC and PID controller. See parameters in
