Gas sampling and gas conditioning technology 5-6.15ME
13 STARTING
Check the correct constellation of the equipment (Fig.1).
W A R N I N G !
False supply voltage can damage the equipment. When connecting
the equipment, please ensure that the supply voltage is identical
with the information provided on the model type plate!

Without gas charging, the floating ball in the flowmeter is in down position. In case of mono-
stable function, the sensor head is mounted on the measuring tube in such a way that the
floating ball is placed in its deepest possible position inside the sensor head and darkens the
light ray of the sensor. The MIN-point can be lifted by placing a limit stop for the floating ball
inside the flowmeter.

Switch on the power supply for the electronic controller. According to the set retardation of
time, the red LED of the electronic controller FA-1.. is beaming - alarm situation.

Bring the floating ball by feeding of gas through the light ray of the flow alarm sensor from the
down position to a position above the sensor head.

According to the set retardation of time (s. 13.1), the green LED of the electronic controller is
beaming - O.K. situation. On the pre-amplifier K-FA-H with mono-stable function, the red LED
is beaming in O.K. situation, the green LED has no function and is always beaming.
The flow monitoring system is ready for operation now.
13.1 ALIGNMENT OF THE DELAY TIME
Unintentional alarms in case of pulsating gas flow can be avoided by this function.
Slow operation: The cutoff of the alarm is delayed (ex works 3 sec.).
Slow release: The alarm release is delayed (ex works 2 sec.).
The alignment of the delay time is described in manual 5-6.10ME, chapter 14.3.
13.2 ALIGNMENT OF THE SENSITIVITY
If in case of alarm no alarm message is set off, an incorrect adjusted sensitivity could be the reason.
In case a complete control system consisting of sensor, light guides, pre-amplifier, electronic control
and flowmeter is ordered, the alignment is made at works. In case the client orders single components
for assembling and the alarm function does not work with other measuring glasses, the adaptation can
be effected.
The alignment of the sensitivity is described in manual 5-6.10ME, chapter 14.2.
