14.1.4. TIMERS parameters menu
All the operational timers can be set on this menu. They are up to 26 general timers splitted into 4 groups:
Note: the timers linked to specic functions are not included in this chapter. Consult the Timers Annex in chapter
"Annex 16 - 2. Timers list", page 88 to have the full list.
14.1.4.1. Operation timers
• FAILURE TIMER (s): time after source is lost, to make sure it’s really lost and start a transfer.
• RETURN TIMER (s): time after a transformer/main source that was off comes back, to make sure it really came back.
• AVAILABLE TIMER (s): time for a genset/diesel generator source to be on and inside the right dened values to be
considered available and ready to accept a transfer.
• S1 DEAD BAND (s): time to wait without load supply (including source failure time and time in center-off / zero position)
when transfering from S1 to S2.
• S2 DEAD BAND (s): time to wait without load supply (including source failure time and time in center-off / zero position)
when transfering from S2 to S1.
Note: by default, S1 and S2 DEAD BAND are the same and set to 3s. On C55 there is no differentiation between
S1 or S2. For ATyS FT technology (I-II switch, with no 0 position), DBT timer does not exist.
Note: see "Annex 16 - 5. Operating sequences", page 96 for operational timer graph and see TIMER Annex for
more details on congurable values for these timers
14.1.4.2. Genset source 1/2 timers
Note: if the source is not linked to a genset the following message will be shown:
- Genset source 1 and source 2 are available if the source is related to a genset (in M/G depending on priority, and in G/G).
• GENSET COOLDOWN (s): This timer will count down once the load leaves the source with a genset, when this timer
expires the genset start signal linked to this source will be deactivated. This timer is used to cool-down the genset before
shutting it down.
• START TIMEOUT (s): Maximum time for the genset to start. After this time, a fault will pop-up saying “Fail to start genset”.
This timer must be greater than the source "AVAILABLE TIMER" or the genset will always be concidered as fail to start.
