Line 1: Time Delay Emergency to Normal
(TDEN)
TDEN delays the transfer from the emergency
back to the grid, permitting the stabilization of the
grid before returning. Timing begins when the grid
becomes available.
Adjustable TDEN time range: 0
0
to 990 sec
Line 2: Time Delay Normal to Emergency
(TDNE)
TDNE delays the transfer from normal to emergency
to permit stabilization of the generator before the
t
ransfer is made. Timing begins when the generator
becomes available.
(sometimes called the warm-up
timer)
Adjustable TDEN time range: 0.0 to 250 sec
Line 3: Time Delay Engine Start (TDES)
This timer prevents nuisance start because of
momentary electrical glitches. If power normalizes
before the countdown ends, the controller skips the
engine start and resets the timer.
Adjustable TDES time range: 0 to 30 sec
Line 4: Time Delay Engine Cool-down
(TDEC)
TDEC permits the generator to run unloaded after
the ATS return to the grid. Timing begins when the
ATS connects back to grid power
(If you already
have cool-down on the Generator Controler this
time is also added to the ATS cool-down timer)
Adjustable TDEC range: 0 to 999 sec
Line 5: Time Delay Center OFF Position
This timer temporally stops the switch in the center
OFF position (completely cut off) before proceeding
to normal. Useful is some computerizes system that
need time in OFF to reset.
Adjustable time delay range: 0 to 99 sec
