It is also possible to configure analogue output 2 with a sub-range which
covers a portion of the temperature span assigned to analogue output 1:
Configuration example PA 40:
Ao1: temperature reading of Lambda 1
650 - 1700 °C ≡ 4 - 20 mA
Ao2: temperature reading of Lambda 1
1000 - 1500 °C ≡ 4 - 20 mA
Digital outputs
One of the following functions can be assigned to each of the digital out-
puts:

Deactivate (This is required when you want to use the digital out-
put as a digital input).

Status LED lights up to indicate that the temperature reading of
Lambda 1 lies within the pyrometer's available temperature range.

Limit switch with adjustable signal threshold:
- Quotient
- Quotient before Min/Max before memory
- Lambda 1
- Lambda 1 before Min/Max
- Lambda 2
- Lambda 2 before Min/Max
- Dirt Alert
- Signal intensity
- Device temperature

Status Signal ATD function.
- Triggered by ATD function Lambda 1 at the end of the
measuring time
- Triggered by ATD function Lambda 2 at the end of the
measuring time
- Triggered by ATD function ratio mode at the end of the
measuring time
- ATD function Lambda 1 indicate the measuring time
- ATD function Lambda 2 indicate the measuring time
- ATD function ratio mode indicate the measuring time
