Case Temp.
Case Temp. high: Set the alarm high value for temperature of
electronics housing. If the value rises above the programmed value
E013 is issued.
Range: 30–75 °C
Case Temp. low: Set the alarm low value for temperature of
electronics housing. If the value falls below the programmed value
E014 is issued.
Range: -10 to +20 °C
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
Contacts, p. 59
Function = Limit upper/lower:
When the relays are used as upper or lower limit switches, program
the following:
Parameter: choose one of the following process values
 Hydrogen
 Temperature
 Sample Flow
 Saturation
Setpoint: If the measured value rises above respectively falls below
the set-point, the relay is activated.
 Parameter Hydrogen: Range: 0.00 ppb –20.00 ppm
 Parameter Temperature: Range: -30 to + 130 °C
 Parameter Sample flow: Range: 0–50 l/h
 Parameter Saturation: Range: 0–200%
