AS: Association of devices
Allows connection/disconnection with the following devices:
– e.sy
Other e.sybox pump for operation in a pump set composed of max 4 elements.
– e.sylink e.sylink input output control unit.
– DEV Any other compatible devices.
The icons of the various connected devices are displayed on page AS with below an identifying acronym and the respective reception power.
An icon lit with a fixed light means that the device is connected and working correctly; a stroked through icon means the device is configured as part of the
network but is not found.
All the devices present over the air are not displayed on this page but only the devices that have been associated with our network.
Seeing only the devices in your own network allows the operation of several similar networks existing within the radius of action of the wireless
without creating ambiguity; in this way the user does not see the elements that do not belong to his pumping system.
From this menu page it is possible to associate and disassociate an element from your personal wireless network.
When the machine starts the AS menu item does not show any connection because no device is associated. In these conditions the message "No Dev"
is shown and the COMM led is off. Only an action by the operator can allow devices to be added or removed with the operations of association and
disassociation.
Association of devices:
Pressing '+' for 5 sec puts the machine into the mode where it searches for wireless association, communicating this status by the blinking of the COMM
leds at regular intervals. As soon as two machines in a working communication range are put into this status, if possible, they are associated with each
other. If the association is not possible for one or both machines, the procedure ends and a pop-up appears on each machine saying "association not
possible". An association may not be possible because the device you are trying to associate is already present in the maximum number or because the
device to be associated is not recognised. In the last case repeat the procedure from the start. The search status for association remains active until the
device to be associated is detected (irrespective of the result of association); if not device can be seen within the space of 1 minutes, the machine
automatically leaves association status. You can leave the search status for wireless association at any time by pressing SET or MODE.
Expresses the fall in pressure with respect to the SP value which causes restarting of the pump.
For example if the setpoint pressure is 3.0 [bar] and RP è 0.5 [bar] the pump will restart at 2.5 [bar].
RP can be set from a minimum of 0.1 to a maximum of 1 [bar]. In particular conditions (for example in the case of
a setpoint lower than the RP) it may be limited automatically.
To assist the user, on the RP setting page the actual restarting pressure also appears highlighted under the RP
symbol.
VPossible values 1 and 2 referring to a rigid system and an elastic system.
The device leaves the factory with mode 1 suitable for the majority of systems. In the presence of swings in pressure
that cannot be stabilised by adjusting the parameters GI and GP, change to mode 2.
IMPORTANT: The regulating parameters GP and GI also change in the two configurations. In addition the GP and
GI values set in mode 1 are stored in a different memory from the GP and GI values set in mode 2. So, for example,
when passing to mode 2, the GB value of mode 1 is replaced by the GB value of mode 2 but it is kept and will
reappear again when returning to mode 1. The same value shown on the display has a different weight in one mode
or in the other because the control algorithm is different.
This is significant only in a multi-pump connection. Set the communication address to be assigned to the device.
The possible values are: automatic (default) or manually assigned address.
The addresses set manually can have values form 1 to 4. The configuration of the addresses must be the same for
all the devices that make up the group: either all automatic or all manual. Setting the same addresses is not allowed.
Both in the case of assigning mixed addresses (some manual and some automatic) and in the case of duplicate
addresses, an error signal is given. The error signal is given by displaying a flashing E in the place of the machine
address.
If the chosen assignment is automatic, whenever the system is switched on addresses are assigned that may be
different from the previous time, but this does not affect correct operation.
Set the measuring system, choosing between metric and Anglo-American units. The quantities displayed are shown
in Table 13.
NOTE: The flow in Anglo-American-speaking units (gal/min) is indicated adopting a conversion factor of 1 gal = 4.0
litres, corresponding to the metric gallon.
