3.5.8. COLLECTIVE SIGNAL OF THE DISPENSER DEFECT – "COLLECTIVE ALARM" (CNG)
For leading the collective signal of the CNG dispenser/module defect a 2‐wire H05VV5‐F 2X0.5 cable is
used (see Table 24) which is routed from the main switchboard in the booth to the communication
distribution box of the dispenser. The H05VV5‐F 2x0.5 cable is routed from the distribution box to the
counter case to relay contacts. Relay contacts shall close in each CNG dispenser defect and open after the
defect is removed.
Table 24 – Identification of wires in the line of a collective signal of the dispenser defect
CAUTION
The max. load of the relay contacts for the dispenser defect indication is 250 V and 2 A. Always
consult the dispenser manufacturer for the use of another control voltage and current.
NOTE
In case of the CNG dispenser/module defect the delivery is interrupted and the display shows the defect
code which corresponds to the defect type – e.g., broken hose, leak in the vehicle storage tank, meter failure,
etc. At the same time, the relay of a collective dispenser defect is activated/switched on which informs the control
centre of the fuel station about the dispenser defect. The relay automatically deactivates/switches off after the
defect is removed.
3.5.9. CABLE CHARACTERISTICS
For installations it is necessary to use cables resistant to common chemicals, oils and with sufficient
thermal and mechanical resistance. These conditions are, for example, met by harmonized cables
H05VV5‐F and H05VVC4V5‐K. The main characteristics of the cables are given in Table 25.
