User Manual Series F-BO-AFE70
Chapter 9 • Connection and parameterisation
If no Purging program has been set (i.e., the rotary switch „Purging program“ SW1 is in one of
the positions „0“, „D“, „E“ or „F“), an activation of the fault input will immediately result in an
activation of the fault output.
All slave units must be operated with Purging program 6.
9.5.2
Internal clock
Every time the supply voltage is applied, the time is automatically set to 10:00.
If a Purging program which carries out a periodical Purging process at 10:00 has been set, the
Purging unit will start the first Purging process immediately after the supply voltage has been
switched on.
The internal clock can only be set to a full hour. If very exact Purging times must be kept to, you
have to use a correspondingly accurate external timer for the control of the Purging processes.
While the time is being displayed or set, the light colour of the status LED is red.
9.5.2.1 Displaying and manually setting the time
Turn the rotary switch „Purging program“ SW1 to the „0“ position. Immediately afterwards the
status LED indicates the hours value of the time as one (one-digit hours value) or two (two-digit
hours value) series of red blink pulses. A series of ten blink pulses stands for the digit „0“.
If the status LED is blinking, for example, 8 times, the set time is between 08:00 and 08:59.
If the status LED is blinking, for example, once, and after a pause of 2 seconds, a further
5 times, the set time is between 15:00 and 15:59.
If the status LED is blinking, for example, twice, and after a pause of 2 seconds, a further
10 times, the set time is between 20:00 and 20:59.
After the indication of the time, you can either set the time anew or terminate the process by exiting
position „0“ of the rotary switch „Purging program“ SW1. Since the clock can only be set to a full
hour, it is recommended that it should always be set at the full hour.
You start the entry by pressing TA1 for at least 2 seconds. When the status LED lights up, release
TA1 and start entering the hours within 4 seconds: if the hours value has two digits (10-24), start
with the tens digit, if the hours value has one digit (1-9), only enter the ones digit.
Press the button once or several times – according to the number you want to enter – with inter-
vals of less than 2 seconds, every press of the button will be confirmed by the status LED which
will light up briefly. The digit „0“ is entered by pressing the button ten times.
2 seconds after the last press of the button, the completion of the entry will be confirmed by the
status LED which will light up briefly.
If the hours value has two digits, you can now start the entry of the ones digit within 4 seconds,
in the same way as described above.
4 seconds after the last confirmation of an entry, the entered hours value of the time will be dis-
played in the same way as already described in this section.
After completion of the entry and indication of the entered value, the status LED will flash in green
because no Purging program has been set.
Since the Purging unit has no built-in back-up battery for the clock, it will immediately lose the
current time in the event of a power failure. If the supply voltage is applied again, it will start
again with 10:00 and will have to be set anew.
If you have made a mistake while entering the time, you can repeat the entry as often as you like.
A switch between summer time and winter time is not provided for, if it is required, you either
have to use an external timer for controlling the Purging processes, or you have to synchronise
the time automatically.
