Page 11: Function
A monitoring logic unit is required for each level pot. For purging, the connecting pipes are individually shut off and reopened in succession, and the level pot is drained. The SRL 6-60 monitoring logic unit monitors compliance with the set times and the sequence of valve operations. - Page 12 ■ ■ 1 x URS 60 or URS 61 safety control unit ■ ■ The SRL 6-60 monitoring logic unit monitors the following times: Interval time ■ ■ This is the interval at which, depending on the operating mode (e.g. 24 h/72 h operation), the con- necting pipes must be flushed.

Page 13: Functional Description Of The Srl 6-60
Function Functional description of the SRL 6-60 The SRL 6-60 monitoring logic unit transmits the data telegram “Alert signal SRL 6-60” to the URS 60 / URS 61 safety control unit in 1s cycles. The SRL 6-60 monitoring logic unit generates the time base for the purging intervals and monitors compliance with these: When the interval has elapsed, the standby time starts and the interval is reset to its initial value. -
