8.3.1. KV 1.0 Fixture for checking the meter outputs

Schematic drawing
Fixture application
Disconnect external equipment from the meter terminal board. Connect fixture KV 1.0 to the terminal board
of the FLONET FN20xx.1 flow meter under test using a flat cable. Make sure that the fixture terminals are
connected to corresponding meter terminals. Switch on the fixture battery. Enter the configuration menu (see
the meter manual).
Checking the analog (current) output: Set fixed current at specific value, e.g. 10.0 mA. Connect Amp meter
into the respective socket contacts on the fixture and check the current value.
Checking output OUT1: Select the "short-circuit (Closed)" mode and check that signal light OUT1 will light
up. Select the "open-circuit (Open)" mode and the same signal light should go out.
Checking output OUT2: Select the "Closed" mode and check that signal light OUT2 will light up. Select the
"Open" mode and the same signal light should go out.
Checking the relay function: Select the "Closed" mode and the signal light associated with the contact
indicating the energised relay status (RELAY OUT CLOSED) will light up. Select the "Open" mode and the
signal light indicating the energised relay status should go out and the signal light associated with the
normally closed contact (RELAY OUT OPEN) will light up.
Checking the dosing function (DOSE START and OUTPUT3): Select the "Dosing Display" mode. The dose
size may be set at 500 liters or otherwise. Return to the "Dosing Display" mode of operation. Press the
DOSE START on the verification fixture. While the key is pressed, the DOSE START signal light will be up
and DOSE OUTPUT3 signal light will be off. Provided the liquid flows or it is simulated by Simulator SF 1.0,
dosing starts immediately. Signal light OUTPUT3 DOSE will light up following completion of the dosing
operation.
Turn the battery switch into the OFF position.
Upon completion of the above checks, disconnect the KV 1.0 fixture from the meter terminal board. Then
connect all co-operating devices and equipment to the unit as they were before. It is also of utmost
importance to restore completely the original settings of all outputs.
