Example:
The following default limits are given:
Rel1: LL = pH 6
Xp (LL) = 3 pH
tF = 70 Imp./Min.
Rel2: UL = pH 8
Xp (UL) = 2 pH
tF = 50 Imp./Min.
pH value = 6 to 8
If the value lies between pH 6 and pH 8 (set range), it is not regulated.
pH value = 3 to 6
If the value sinks below pH 6, Rel 1 is regulated between 0 and 70 pulses/min
pH value < 3
If the value sinks below pH 3 (except for Xp/LL), it is further regulated using Rel 1
by 70 pulses/min.
pH value = 8 to 10
If the value rises above pH 8, it is regulated using Rel 2 between 0 and 50
pulses/min.
pH value > 10
If the value rises above pH 10 (except for Xp/UL), it is further regulated using Rel 2
by 50 pulses/min.
