START-UP OVERRIDE
There are application scenarios in which fan motors and measuring instruments are switched off and on again.
When switched on, the fans take a few seconds to build up a flow.
During this start-up time, the GLT could switch to fault mode (lack of flow).
In the KLGFxx / KLSWxx (without display), the start-up override (60 s) is activated by a DIP switch.
In the KLGFxx LCD / KLSWxx LCD (with display) and in the KLGFT / KLGFVT LCD ,
the start-up override (0...120 s) is activated and adjusted by a potentiometer.
After the supply voltage is switched on, a flow of 20 m/s or greater than the set switching threshold during
this start-up time is assumed and the output signal is increased to 10 V or the relay is switched, depending on the type.
After the start-up time has elapsed, the unit switches to normal measuring mode,
in unit types without a changeover contact, a voltage proportional to the measured value is output,
in unit types with a changeover contact, the relay switches according to the measured value < switching threshold
or measured value > switching threshold.
SWITCHPOINT
In unit types with a changeover contact, the switching point (0.1...20 m/s) is adjusted by a potentiometer.
OTHER PARAMETERS
In the KLGFT / KLGFVT LCD , the temperature is captured by another sensor (NTC 10k).
In the KLGFVT LCD , the alternative parameter Volume Flow is calculated internally.
This value can be shown instead of the flow in the display. The switching is menu-controlled on the display.

Note: Changeover contact with automatic reset
(relay opens automatically when value falls below the threshold again)
AOS ( Automatic Output Switching ) = patented analogue interface (patent no. DE 10 2015 015 941 B4),
the unit automatically detects the required output type 0 - 10 V or 4...20 mA
T = temperature (0...+50 °C) – additional measurand
V = volume flow (0...200,000 m³/h) – alternative parameter, can be configured via display!
