Flow Rate
For basic function of the CCS, a flow signal is not necessary. With a flow signal, the CCS can
calculate exact water average values. The flow can also be used as a trigger for the water
monitoring, and the flow gets logged by the datalogger, if connected.
When you connect a flow meter, you need to know the signal type. The CCS can work with
pulse-based flow meters and with analog flow meters with a current range between 0..20mA
and 4..20mA. Please check signal type of your flow meter. Use the upper table to connect
the flow signal properly.
2.3.1 Analog Flow Meter
When using an analog
flow meter, use the ANALOG_4 terminal panel. The “mA”-Terminal is
the path where the given current flows in. For Ex-i safety, a barrier is needed. The barrier
connects between flow sensor and CCS ANALOG_4 input. To power and ground the barrier
or sensor, you can use the “24V”, “GND”, an “PE” connector of the terminal.
2.3.2 Pulsed Flow Meter
When using a pulse-based flow meter, use the PULSE_1 terminal panel to connect the
sensor. Connect the pulse output of the sensor to the PULSE connector. To power and
ground the sensor, you can use the “24V”, “GND”, an “PE” connector of the terminal.
The Voltage-Level of the Pulses must be between 12V and 24.
The Pulse-Input has an optional 10k
Ω-Pull-Up-Resistor, which can be activated by the slide
switch. This will connect the PULSE-Input via the Pull-Up-Resistor to 24V.
Use Only for flowmeter output with low-active pulses (NPN)
2.4
SLUGGUARD®
A SLUGGUARD® is a binary sensor which indicates water slug in pipes or vessels. The
SLUGGUARD® can trigger water alarms in the CCS. It is an optional sensor. It must be
connected to the
DI2
connector in the DIGITAL_INPUT terminal panel. For Ex-i safety, a
barrier between SLUGGUARD® and CCS will be needed.
2.5
Interlock
The optional interlock signal is an optional signal which can be connected to the CCS to
detect when a refuelling process starts.
This has no effect on the clearance of the alarm
and warning relays.
It effects on the evaluation of the refuelling process
(data logging…).
When the truck
gets parked under the aircraft and the operator takes the refuelling equipment out of its
storage place, a binary signal gets created. You can connect a 24V interlock signal to the
CCS which tells the system when the refuelling truck refuelling one aircraft. 24V means,
refuelling process is active (truck parked under the aircraft). 0V means, that there is no
refuelling process and no evaluation.
If you do not connect an Interlock signal, the detection of a refuelling process works in
another way (triggered by water monitoring).
The 24V interlock signal gets connected to the DI1 connector in the DIGITAL_INPUT
terminal panel.
