9.4. One TCM port controls a number of pumps
It is possible to control several pumps with only one solenoid valve, that is all pumps starts if one dispense point is
opened. To do this the solenoid valve is connected b24V and Sol of a TCM port. The port is set to a tank
that does not exist in the PC database and the Mask is set to 0.
For all PC tanks that should be controlled by this solenoid valve the TCMAddress and TCMPort should be set to
this port. Using the WinDB Manager does this.
If this method is used of coarse no level sensor can be used.
10. EX-barrier 23187 for discrete level sensors.
An EX-barrier is needed between the level sensor and the tank module if the
liquid is classed as flammable. For this purpose the EX-barrier 23178 and a
special EX approved cable 23164 can be used.
The EX-barrier, the solenoid valve that controls the air to the pump and the tank
module should be placed outside the EX-classed area. The EX approved cable
should be used to connect the level sensor on the tank inside the EX-classed area
with the EX-barrier outside the EX-classed area.
Connecting a fresh oil tank 23171/23183 (1-Level).
To achieve a proper function, that is the pump starts only if there are enough oil
in the tank, a dispense point is open and the sensor works properly, the
following connection should be made.
The TCM port should be set to control the appropriate PC tank in relation to the
physical tank.
Correct TankType, TCMAddress and TCMPort should be set using with
WinDB Manager
Mask = 4, TankType=01?
