KLGF 1 ⁄ KLGF 2
ATTENTION!
Trained specialist personnel must execute connection and putting in operation! Mains connection (L, N) is to be made via fused breaker
switch with the usual cutout elements. Electric installation must on principle follow the general VDE directives (VDE 0100, VDE 0113,
VDE 0160).
Putting in operation – KLGF 1 ⁄ 2
Specialist personnel must execute connection and putting in operation!
For putting in operation and calibrating the devices, the following procedure is practical:
• Install flow monitor and make electrical connections according to mounting and installation instructions.
• Switch on mains voltage, then turn on nominal flow.
• At the KLGF 1 ⁄ 2, calibrate the respective output signal to the nominal flow using the »Amplification« potentiometer. For example,
for nominal flow 5 m ⁄ s, calibrate signal output U to 5 V, for nominal flow 10 m ⁄ s, calibrate signal output U to 10 V
• The flow meter is now operable.
The device is now set to monitoring function.
What to do when air flow monitor doesn't function
Problem
KLGF... doesn't
function at all
KLGF... doesn't
recognize flow
KLGF... shows changed
responding behaviour
In the KLGF 1 ⁄ 2, sensor and control device form one compact unit. The sensor tube is also used for mounting. With KLGF 1 ⁄ 2, the rela-
tive intensity of flows can be indicated and evaluated. At the device, you can adapt the analog output range to the existing flow conditions
by setting the desired output voltage (max.10 V) at maximum flow.
Intended use
Series KLGF 1 ⁄ 2 flow monitors are used for monitoring flow rates in gaseous media within specified technical data limits. Main fields of
application are air conditioning and ventilation technology in sectors of building and facility automation.
Mode of operation
Series KLGF 1 ⁄ 2 flow monitors function on the calorimetric principle and provide a 0...10 V output signal analog to flow velocity.
