Security Line (Stop Button); Regulation Of Valves In Pressure Sections Outside Dispenser (Cng Module) - tatsuno OCEAN TOWER Series Installation And User Manual

Fuel Dispensers TATSUNO EUROPE ‐ Installation and User Manual , revision 10, January 2022
a.s. about the necessity to install service lines. For service lines we recommend using multi‐wire shielded
H05VVC4V5‐K cables (0.5 mm
3.5.6. SECURITY LINE (STOP BUTTON)
The security line serves to output the signal from the STOP button located in the dispenser to the station
switchboard security circuits. The security line must be especially installed in LPG and CNG
dispensers/modules that operate in an unattended mode. Pressing the STOP button on the dispenser
activates the security circuits that disconnect the dispenser from the power supply and at the same time
the safety valves on the supply line close.
In order to install the security line it is necessary to route the 3‐wire power cable H05VV5‐F 3x1.5 (see
Table 22) to each dispenser at the fuel station. The security line cable is always brought from the main
switchboard in the booth to the first module of the dispenser into the distribution box. From the
distribution box, the cable is routed to the dispenser electronic head where it is connected to the STOP
button.
3.5.7. REGULATION OF VALVES IN PRESSURE SECTIONS OUTSIDE DISPENSER (CNG MODULE)
If the valves from high‐pressure sections are located at the CNG fuel station outside the dispenser in the
area of pressure reservoirs and compressor then their switching is performed by a 5‐wire H05VV5‐F 5G1.5
cable (see Table 14). The cable from valves regulation is routed from the main switchboard in the booth
to the supply distribution box of the dispenser. The H05VV5‐F 5G1.5 cable is routed from the distribution
box to the counter case to the outputs that ensure the valves regulation.
Table 23 – Identification of wires in the cable for regulating the valves in CNG pressure sections
CAUTION
In order to regulate external valves the dispenser outlets are used that use the voltage of 24V DC
with maximum current‐carrying capacity of 0.8 A for switching. Always consult the dispenser manufacturer for
the use of another control voltage and current.
