2.6
Trigger
When there is no possibility to install a flow meter or a DP transmitter, the system needs a
binary trigger, otherwise, there is no need to connect it. The trigger tells the system if there is
a refuelling now. This condition activates the water monitoring with the AFGUARD®.
Do not
mix up the trigger with the interlock signal!
The trigger is usually the output of a Deadman. It must be a 24V signal. Connect the signal to
the
TRIGGER
connector in the CONTROL terminal panel.
2.7
Reset
When an alarm occurs, it must be reset to continue refuelling. You can reset it by software
over the web visualisation with a smartphone or a computer by entering a PIN or you can use
the hardware reset. This is usually a key switch. In the CONTROL terminal panel, there is a
connector called
RESET
, connect the reset switch to 24V and RESET, that the current path
gets closed when applying reset.
2.8
Water Indicator
To indicate water warnings and water alarms to the operator, a blue flashlight should be
connected to the CCS. The 24V Light must be connected between the
DO1
of the
DIGITAL_OUTPUT terminal panel and GND.
2.9
Relay Outputs
The CCS has 4 relay outputs.
REL_1
Water Alarm (AFGUARD®s and SLUGGUARD®)
REL_2
Water warning(s) (AFGUARD®s)
REL_3
Free programable (Default: Ready Relay)
The Ready Relay gets activated if the monitoring is active (blue lamp on) and
the CCS is NOT in Alarm Mode.
REL_4
Free programmable (Default: deactivated)
REL_1 and REL_2 have an inverted logic. This means, the relays are triggered if everything
is okay. The relay releases if a warning/alarm/error occurs.
2.10
Power Supply
The CCS works with a power of 24V DC ±10 %, Residual ripple 5 %.
In the SYSTEM terminal panel, the supply voltage must be connected. Use the 24V and the
GND terminal to connect the power supply. Optionally use
PE
to ground the CCS.
