At all digital inputs:
- Time settings: A debounce time can be selected, that is, a period the signal at least must be
present at an input to be detected.
 Digital output mode. Output of a switching signal:
- No function: The output is deactivated (settings right beside have no
function).
- Ready contact: Device is ready and error free after self-test.
- Material contact (only M3) for detecting whether a hot part is in the
measuring field: The limit switch contact is switching, when the beginning
of the temperature range is exceeded by 1% of the temperature range
span (the clear time of the peak picker has to be set to ≥1 s or to Auto).
- Limit switch contact: if a certain temperature is exceeded or falling below a threshold.
- Internal device temperature: When exceeding a maximum defined device temperature.
Additionally when equipped with a PID controller:
- Setpoint limit 1 / Setpoint limit 2: The setpoint limit is a limit tempera-
ture above or below the setpoint temperature that should not exceeded or
to be below. Two setpoints can be defined. The output is activated if the
measured value exceeds the defined setpoint value. The output is also
activated if the measured value falls below the defined value. Entry of the
setpoint value has to be done relative to the setpoint, positive or nega-
tive, e.g. 20°C if the setpoint value is 800°C and the output should be ac-
tive at 820°C. Values will be entered in the PID controller form
(see 7.2.4).
- The setpoint band is composed of the 2 setpoint limits and de-
fines a range within the temperature has to be. The output is ac-
tivated if the measured value is outside the defined value.
- Controller active: Output is active when the controller is active.
- Successful control: Output is active when a control process is
terminated (a possibly hold time has elapsed).
Various settings:
- Switching value: Activates the corresponding output at the set switching value (the LEDs 1-3 on
the unit indicate the activated state).
- Hysteresis: The hysteresis is the value at how many degree below the limit value the output is
switched back.
- Logic: The state of the digital outputs can be set:
- NO (normally open): outputs have in active state 24 volts to the pins and in inactive state 0 V
(output max. 50 mA, current limited internally).
- NC (normally closed): outputs have in active state 0 volts to the pins and in inactive state 24 V
(output max. 50 mA, current limited internally).
- Extended settings: Depending on the selection are either available:
Time settings: A verification time and a hold time can be set:
- Verification time: select “immediately” to activate the output function immediately when hap-
pening. A time between 1 and 65535 ms delays the activation accordingly.
- With the hold time, the output can be kept active longer than the original signal.
- None: signal is active as long as the function is active
- Process start: signal is active up to the next start (of a program or at manual start)
- Time value (between 1 and 65534 ms): after activation, signal is held for the entered time.
