Switching Of Pumps Located Outside The Dispenser - tatsuno OCEAN TOWER Series Installation And User Manual

power supply is led to the dispenser electronic head where it provides a stabilized supply of the electronic
counter, switching elements and possibly additional heating elements.

From the dispenser the power supply for the counter is led to the main switchboard where it is connected
to through the 230V/6A circuit breaker to a common bus for all dispensers. From this point the power
supply for all dispensers is led to the stabilized backup power source which will supply the dispenser
counter for 3‐5 minutes in case of power failure.
RECCOMENDATION
recommends backing up the stabilized power supply of the dispenser by a UPS (Uninterruptible Power Supply).
Very frequent phenomena in the electricity network are power failures, strong interference or voltage fluctuations
in voltage peaks (especially in winter season). All such phenomena may be eliminated by using a correct backup
UPS. There are basically two types of backup power supply sources for dispensers: UPS of a line‐interactive type
and UPS of an on‐line type. For fuel stations connected to a stable electricity network (without voltage fluctuations
and interference) UPS of a line‐interactive type is sufficient. In other cases, it is necessary to use UPS of an on‐line
type. Interference and fluctuations or power failures may cause frequent blocking of dispensers, communication
errors between a computer and dispenser, computer failures (data loss), etc.
3.5.3. SWITCHING OF PUMPS LOCATED OUTSIDE THE DISPENSER
Switching of pumps located outside the dispenser (submersible pumps, LPG, WSE, AdBlue...) is carried out
at the dispenser via the 3‐wire power cable H05VV5F 3x1,5 / (see Table 18) or via the 7‐wire H05VV5
power cableF 7x1,0 (Table 19) depending on how many external pumps need to be switched. The
switching power cable is always brought from the main switchboard in the booth to the first hydraulic
module of the dispenser into the distribution power supply box. From the distribution box, the power
supply is led into the dispenser electronic head where it is connected to power relays enabling the
switching of LPG, WSE, AdBlue® pumps or submersible fuel pumps for gasoline and diesel in the pressure
system.
