5.3.2 and 5.3.3 Relay 1 and 2: The function of relay contacts 1 or 2 are defined by
the user
NOTICE: The navigation in the menu <Relay 1> and <Relay 2>
is equal. For reason of simplicity only the menu numbers of
Relay 1 are used in the following.
1 First select the functions as:
- Limit upper/lower,
- Control upwards/downwards,
- Timer
- Fieldbus,
2 Then enter the necessary data depending on the selected func-
tion. The same values may also be entered in menu 4.2 Relay
Contacts, p. 74
When the relays are used as upper or lower limit switches, program
the following:
5.3.2.20 Parameter: choose one of the following process values
Oxygen
Temperature
Sample Flow
Saturation
5.3.2.300 Setpoint: If the measured value rises above respectively falls below
the set-point, the relay is activated.
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.
5.3.2.1 Function = Limit upper/lower:

Parameter Range
Oxygen 0.00 ppb –20.00 ppm
Temperature 0–100 °C
Sample flow 0–50 l/h
Saturation 0–200%
