Digital Interface; Functional Inputs - MICRO-EPSILON CTVM-1L Instruction Manual

Digital Interface

The CTVideo sensors are equipped with an USB interface. The
interface board is located beside the LCD display. To uninstall the
board please disconnect both of the M3x5 screws. Please pay
attention to the correct positioning of the pin strip if you install the
board.

Functional Inputs

The three functional inputs F1 – F3 can be programmed with the software, only.
F1 (digital): trigger (a 0 V level on F1 resets the hold functions)
external emissivity adjustment [0 – 10 V: 0 V ►  = 0,1; 9 V ►  = 1; 10 V ►  = 1,1]
F2 (analog):
F3 (analog): external compensation of ambient temperature/ the range is scalable via software
[0 – 10 V ► -40 – 900 °C / preset range: -20 – 200 °C]
F1-F3 (digital): emissivity (digital choice via table)
A non-connected input represents:
F1 = High | F2, F3 = Low.
High level: ≥ +3 V ... +36 V | Low level: ≤ +0,4 V ... –36 V]
