TIMERS VALUE
Definition
Source 2 (Genset) Starting Timeout Notification: Timer
countdown begins as soon as the genset start order
has been given. If 2AT has not been satisfied before the
countdown of this timer, the message "FAIL START" will
be displayed. In order for the FAIL START message not
2ST 0030 SEC
to be displayed, the generator must have started and be
considered available within this time.
Note: The display of this notification does not affect
the operation of the ATS.
Dead Band Timer
This is the minimum load supply blackout time allowing
residual voltages that may be generated by the load (such
ODT 0003 SEC
as motors) to decay.
This is not necessarily a stop in 0 position, when a transfer
is initiated after a loss of source, the timer starts at the
same time as 1FT/2FT.
Test On Load Limited (LIM) / Unlimited (UNL) duration.
LIM is to be selected when associating the test to a
duration timer such as TOT.
Note 1: If the value is set at UNL, the TOT is stopped
TOT UNL
either when the input is opened, or via the validation key.
Note 2: When set to UNL, the test on load duration timer
is deactivated as the duration becomes unlimited.
ATTN: Set to UNL when using the engine exerciser
Test On Load Duration Timer:
This timer defines the On Load Test time. It starts
counting when the Test is initiated.
TOT 0000 SEC
Note: TOT is visible in the timers menu when TOT
(LIM/UNL) above is set to LIM.
Test On Load – End Delay Timer: This time delay starts
T3T 0000 SEC
counting at the end of TOT Timer. The return to the main
supply takes place at the end of T3T time.
Test Off Load Limited (LIM) / Unlimited (UNL) duration.
LIM is to be selected when associating the test to a
duration timer such as TFT below.
Note 1: If the value is set at UNL, the TFT is stopped
TFT UNL
either when the input is opened, or via the validation key.
Note 2: When set to UNL, the test on load duration timer
is deactivated as the duration becomes unlimited.
ATTN: Set to UNL when using the engine exerciser
Test Off Load - Duration Timer:
This time delay defines the On Load Test time. It starts
counting when the Test is initiated. The return to the
TFT 0600 SEC
main supply takes place at the end of TFT.
Note: TFT is visible in the timers menu when TOT
(LIM/UNL) above is set to LIM.
External Order Test On Load - Start Delay Timer. This time
delay starts at the same time as the External On Load
Test (EON) order is received. At the end of this time delay,
the Genset start order is activated. Once source supply 2
E1T 0005 SEC
is available, the load is transferred to source supply 2.
Note: E1T is visible in the timers menu when at least
1 input is configured as EON.
