The Open Warning Delay can be enabled or
disabled in either "Auto Control Mode" or "Remote
Control Mode". Open Warning Delay is always
enabled in "Manual Mode".
Re-Close Delay
XXX Sec
After a Close command is issued, regardless of
mode of operation, a Re-Close time delay must
time out before the control will respond to a Close
command, regardless of the mode of operation
calling for a Close. The Re-Close Delay defines
the minimum time that the control will wait before
allowing a Close operation after an Open operation.
This delay is indicated on the LCD display by a
cycling message indicating how much time is left
before a Close operation can be executed. The
purpose of this is to allow any residual charge on
the capacitor bank time to drain off through the
internal bleeder resistors of the capacitors in the
capacitor bank prior to Re-Close. The time delay is
user selectable from 300 to 600 seconds with a 300
second default setting. The timing accuracy is ± 5%.
Switch Control Type
Solenoid Driven
The Switch Type can be set to either "Solenoid
Driven" or "Motor Driven" which determines the
Close/Open Pulse range as either seconds or
milliseconds.
Close/Open Pulse
XX Sec or msec
Close/Open Pulse Duration is the period of time that
the Close or Open contact stays energized. Based
on Switch Type selection. It can be 50 to 100 msec
for a Solenoid Driven Switch or 5 to 15 seconds for
an Motor Driven Switch.
Minimum Time B/N OP
X Sec
The Minimum Time Between Operations feature
allows the user to inhibit any Automatic timing
toward an operation until the Minimum Time
Between Operations timer has timed out (0 to 3600
seconds). The timer only applies to the Auto Control
Mode and will not prevent operations required as a
result of Control Mode Limits be exceeded.
Temp Unit
Fahrenheit
Provides user with the ability to set the Temperature
Units to either Celsius or Fahrenheit.
