Electrical installation
Connecting the "Result 2" switching output:
Connect the output as shown for example.
Important
If the "Device Ready" function is chosen, the ICR845-2 outputs a static pulse in Reading
mode.
Recommendation
To check the switching functions using a high-impedance digital voltmeter, wire the out-
puts with a load resistor to prevent incorrect voltage values/voltage statuses from being
displayed.

Characteristics
– Short-circuit-proof + temperature protected
– not electrically isolated from V
S
– Pulse duration based on setting:
10 to 990 ms, 00: static (to the end of the next reading pulse)
Function assignment
(default setting)
"Good Read" (100 ms),
Level: not inverted (switching output becomes alive (high) when the event
occurs in the reading procedure)
