VYPER SCREEN SETPOINTS
The Vyper
™
Screen
(See Figure 43) contains setpoints and
information pertinent to the operation of the Vyper
™
such as
internal currents, voltages, and temperatures. This screen also
gives detailed information on some external equipment such
as the circulation pump and the motor temperature.
The Service Level 2 Vyper
™
Screen is similar to Level 1, but
adds the capability of adjusting several setpoints, as follows:
Standby Time:
The VSD enters Standby mode when there
is no load on the VSD. The VSD capacitor banks remain
charged and the compressor output is 0 Hz. Standby mode
permits fast acceleration when the load returns. If the time
of zero load surpasses the Standby Time setting, the VSD
will need to go through a restart sequence. The values for
Standby mode can be set from 20 to 120 minutes.
Clear Standby Time:
This option can be pressed to clear the
Standby time value from the VSD if not desired.
Clear VSD Memory:
Clear the existing trending values in
the Vyper
™
memory.
Clear Total kWh:
This function clears the accumulated kWh
totals from the counter since the last reset. The value returns
to zero upon selecting this option.

™
screen parameters display measured
