Define the mea- suring value, which should issue an alarm high respectively low. 5.3.1.6.1 Alarm High: If the measured value rises above the alarm high val- ue, the alarm relay is activated and E039 is displayed in the mes- sage list.
  • Page 99 AMI Codes-II CC Program List and Explanations 5.3.2 and 5.3.3 Relay 1 and 2: The contacts can be set as normally open or nor- mally closed with a jumper. See Relay 1 and 2, p. The function of relay contacts 1 or 2 are defined by the user.
  • Page 100 AMI Codes-II CC Program List and Explanations 5.3.2.400 Hysteresis: within the hysteresis range, the relay does not switch. This prevents damage of relay contacts when the measured value fluctuates around the alarm value. Parameter Range Free av. chlorine 0–10 ppm Total chlorine 1 0–10 ppm...
