The following setpoint keys are removed from this
screen:
• Local Motor Current Limit
• Pulldown Demand Limit
• Pulldown Demand Time
Surge Map Screen
When in Modbus protocol configuration, a SURGE
MAP screen displays the surge map in a table or list
form when the MAP VIEW key is selected on the
SURGE MAP screen.
With the MAP VIEW set to TABLE, as shown in
Op-
tiView Control Panel – Operation (Form 160.54-O1)
FIGURE 37
, the map is shown graphically. The X-Axis
is Delta P/P and the Y-Axis is PRV position. Each VSD
frequency point is represented by an
X
in the table. The
present operating conditions are indicated with an as-
terisk (*) and are detailed at the bottom of the screen
under PRESENT, as shown in
OptiView Control Pan-
el – Operation (Form 160.54-O1) FIGURE 37
. If the
present condition is the same as a mapped point, the
* will be replaced by an
O
. To view the details of any
mapped point, position the green box (□) over the de
-
sired
X
using the keypad arrow (▲▼◄►) keys. The
VSD output frequency, Pre-rotation vanes position and
selected point's Delta P/P is displayed at the bottom of
the screen under SELECTED. The default position for
the □ is in the upper left corner of the view window.
Once moved, it will remain at the last position. The
speed decrease inhibit-surge map point LED, Mapping
inhibited LED and ACC surge detected LED are also
on this screen. They function the same as the duplicate
LEDs on the ACC DETAILS screen.
With the MAP VIEW set to LIST, as shown in
Op-
tiView Control Panel – Operation (Form 160.54-O1)
FIGURE 38
, the Delta P/P, PRV Position and VSD out-
put frequency of each mapped point are listed in rows.
This is the same report that is generated when the surge
map is sent to a printer. Therefore, this view cannot be
selected while a print is in process. The PAGE UP and
PAGE DOWN keys are used to scroll to the previous
or next listing.
Hot gas bypass Screen
The hot gas bypass control mode data box on this screen
now displays minimum load, VSD or VGD, based on
the actual override in effect. Previously, OVERRIDE
was displayed as a general message for any of these
conditions. See
Override
In previous software versions, when the drive was run-
ning less than full speed, normal hot gas operation, in-
cluding the minimum load operation was overridden and
the Hot gas bypass Valve was driven to the fully closed
position. In this version, the Minimum Load function is
allowed to operate even when the VSD is at less than full
speed. The Minimum Load function opens the hot gas
bypass valve to the maximum allowed by the maximum
open setpoint (25% to 100%) when the LCLT decreases
to less than the minimum load setpoint, programmed as
an offset below the LCLT setpoint.
The surge detected LED is replaced by a surge avoid-
ance surge detected LED. It illuminates momentarily
when a surge is detected by the surge protection fea-
ture. If equipped with a VSD (YORK or Modbus pro-
tocol configuration) or MV VSD, this feature only
detects surges that occur while the drive is running at
maximum frequency.
An ACC surge detected LED was added to this screen
when in Modbus protocol configuration. It illuminates
momentarily when a surge is detected by the ACC
function in the microboard while the drive is running
at less than maximum frequency.
The surge avoidance surge count is the total surges ac-
cumulated by the surge protection feature. If the unit
is equipped with a liquid cooled solid state or elec-
tromechanical starter, it is the total surges detected.
If equipped with a VSD (YORK or Modbus protocol
configuration) or MV VSD, it is only the surges detect-
ed while the drive is running at maximum frequency.
OptiView Control Panel – Operation (Form 160.54-
O1) FIGURE 36
shows this screen in Modbus protocol
configuration.
