10.- Operation test (Bump Test)
Materials required:
AKO-58110
calibration kit
Gas cylinder*
EN-378
and
F-GAS
international standards require verification of the correct operation of the
transmitter at least once per year. Please check what current local regulations specify for such cases.
Always ensure that you comply with current local regulations.
Ÿ
Before starting the verification procedure, check the Pre-Alarm configuration (
AL2
). This should be enabled
in order to check it has been activated. It is advisable to disable the Pre-Alarm delay (
AL5
) and Alarm delay
(
AL8
) to speed up the verification process.
Ÿ
Install the
AKO-58110
calibration kit following the instructions on page 18.
Ÿ
Open the shut-off valve of the gas cylinder and wait.
Ÿ
After a few moments, the transmitter concentration reading will begin to rise until it reaches the Pre-Alarm
and then Alarm level.
Ÿ
Check that both the Pre-Alarm and the Alarm signal correctly and that the corresponding relays are
activated.
Ÿ
Close the shut-off valve of the gas cylinder, disconnect the cylinder and remove the calibration kit from the
transmitter.
The transmitter may take a few moments to go back to showing the concentration values from before
the verification procedure.
Once the verification procedure is complete, remember to readjust the Pre-Alarm (
AL2
) and delay (
AL5
and
AL8
) parameters to the values prior to the beginning of the verification procedure.
*Use a cylinder with a type of gas that is suitable to the sensitivity of the transmitter to be calibrated. When
calibrating the
AKO-575400
universal gas transmitter, use a R134a gas cylinder.
