Temperature Unit; Configurable Inputs / Outputs; Digital Input Mode - KPM PROCESS SENSORS METIS M311 Operating Manual

- Upscale burnout: when the pyrometer field of view is suddenly obscured, the output is set to the maxi-
mum current of 20 mA instead of the standard 0 or 4 mA output. This function can, for example, be desir-
able for furnace monitoring if the control would otherwise detect a cold furnace and heat it up fully, possi-
bly burning it out.
If the upscale burnout function is used together with a reduced beginning of temperature range (under
"Adaptation"), this means that 20 mA are set to the output, before the pyrometer's beginning of tempera-
ture range is reached, not 0 or 4 mA.

7.1.5.7 Temperature Unit

The temperature can be displayed and entered in °C or °F. Changing the mode will not change
the entered values, no conversion will be done.

7.1.5.8 Configurable Inputs / Outputs

The 3 inputs / outputs can be set as a digital output or input or port 3 as an analog input and assigned a func-
tion (for connection see also

Description / switching trigger
A switching signal at the input has no effect.
Resets the maximum value of the maximum value memory by contact.
(devices with laser targeting light only) Turns the targeting light on or off.
(only devices with PID controller) Activates the control as long as voltage is present
at the connection.
(only devices with PID controller) Starts or stops the controller with each pulse (alter-
nately).
To call up and activate up to 7 pyrometer configurations (incl. control parameters for
devices with PID controller).
The inputs are binary coded, i.e.
▪ with one digital input only one Setup can be activated
▪ with 2 digital inputs there are 3 Setups available
▪ using all 3 inputs, 7 Setups can be accessed and activated
Setup 1
Setup 2
Setup 3
Setup 4
Setup 5
Setup 6
Setup 7
A debounce time can be selected, that is, a period the
signal at least must be present at an input so that it
can be recognized and processed by the system (3 ms
are specified by the pyrometer hardware). Values: "immediately" (0) to 1 s.
