Type of action: End time

If you wish to program an action with an operating range that covers 2 consecutive 
days of the week (e.g. Monday between 22:00 and 03:00 on Tuesday), program 
the action to end at 23:59 on Monday and the same action to start at 00:00 on 
Tuesday.

Possible actions that can be scheduled are (in order of priority):

 

Lock (BLOQ):

 prevents the genset from being started and inhibits the 

activation of the contactor.

 

Forced start (ARRF): 

starts the genset and activates the contactor.

 

Test (TEST): 

 starts the genset without activating the contactor; in 

the event of receiving an external start command.

 

Free (----):

 no action is scheduled for that range; the start time and 

end time have no effect.

The timer option allows up to 5 different actions to be programmed on the same 
day. For each option is activation range is defined indicating the hour and minute 
of the start and end; the start time must always be before the end. The start 
time and end time are between 00:00 and 23:59.

From version CEx7 rev4.71 the frequency of the event can be programmed:

 

Weekly (option [0]).

 Every week the scheduled event is carried out.

 

Monthly (option [1]).

 Only during the first week of the month (days 

1-7 inclusive) is the scheduled event carried out.

 

Bimonthly (option [2]).

 Only during the first week (days 1-7 inclusive) 

and third week of the month (days 15 to 21 inclusive) is the 
scheduled event carried out.

Choose a day and confirm (V), the start hour (V), (V), start minute (V), end hour 
(V), end minute (V). To select program 2-3-4-5 use (+) (-) and repeat the above 
process.
