Control Mode Limits Settings
Remote Control Mode –
The control opens and
closes the bank based on commands received
through communications. The Remote Control Mode
has its own set of "Overvoltage" and "Undervoltage"
limits which can be enabled to block remote
commands, should they result in bank voltages
beyond the limits. If voltage should exceed these
limits, the control will also initiate the appropriate
Open or Close command. This is determined by
a running average of voltage differential recorded
during recent switching operations of the bank. A
"HeartBeat" or "Keep Alive" signal must be received
from the SCADA Control system on a user defined
periodic basis, or the control will determine the
communications link to be inoperable and revert
to one of the automatic modes of operation. This
continues until the control receives two valid
"HeartBeat" signals within the predetermined
interval and will then revert to Remote Control
Mode. If the Control Mode Limits are enabled in
Remote and the Remote Mode limits are disabled,
the control will perform the blocking as described
above, but will not initiate any operation on its own.
The Control Mode Limits are used as outside limits
to the auto and remote control mode. The control
will inhibit the operation if the resulting calculated
load voltage (Vm-
∆
V) is below or above the voltage
settings of the Auto or Remote control mode.
Local Manual Mode –
The control can be disabled
from the above modes of operation by a front panel
toggle switch and will respond only to front panel
"Close" and "Open" switch commands when placed
in "Local Manual" mode. The control can only be
returned to Automatic or Remote Operation by
returning the front panel switch to the "Remote/
Auto" position.
When Control Mode Limits are enabled in Manual
mode, the control will inhibit a manual Close
command if the load voltage is already below the
Minimum Voltage Limit. Similarly the control will
inhibit a manual Open command if the load voltage
is already above the Maximum Voltage Limit. Note
that the Definite Time Delay does not apply to Manual
Control Mode Limits.
