User Manual Series F-BO-AFE70 Chapter 9 • Connection and parameterisationIf no Purging program has been set (i.e., the rotary switch „Purging program“ SW1 is in one ofthe positions „0“, „D“, „E“ or „F“), an activation of the fault input will immediately result in anactivation of the fault output.All slave units must be operated with Purging program 6.9.5.2 Internal clockEvery 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, thePurging unit will start the first Purging process immediately after the supply voltage has beenswitched on.The internal clock can only be set to a full hour. If very exact Purging times must be kept to, youhave 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 timeTurn the rotary switch „Purging program“ SW1 to the „0“ position. Immediately afterwards thestatus LED indicates the hours value of the time as one (one-digit hours value) or two (two-digithours 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 further5 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 further10 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 exitingposition „0“ of the rotary switch „Purging program“ SW1. Since the clock can only be set to a fullhour, 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, releaseTA1 and start entering the hours within 4 seconds: if the hours value has two digits (10-24), startwith 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 whichwill 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 thestatus 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 greenbecause no Purging program has been set.Since the Purging unit has no built-in back-up battery for the clock, it will immediately lose thecurrent time in the event of a power failure. If the supply voltage is applied again, it will startagain 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 eitherhave to use an external timer for controlling the Purging processes, or you have to synchronisethe time automatically.I56-4252-010D200-104-0037
