unique, i.e. the devices connected to one line of power and communication must not have
the same addresses.
Note
– The signal device default address (set by Manufacturer) is 88. It is recom-
mended to set the signal device address within the range from 82 to 92.
If signal device address is unknown, then input of 255 addresses (self-request) shall
enter the signal device configuration settings.
Viewing or altering of address shall be performed in accordance with 2.4.4.1,
2.4.4.2:
-
enter transducer configuration menu;
-
Scroll to and select
inFo
menu item;
-
scroll to
Ad
sub-item, current value of address shall be displayed on the indicator
board;
-
- to change, enter
Ad
sub-
item and type new transducer’s address;
-
scroll to
End
item and exit with saving changes.
The controller software number is pointed in
inFo
menu item. Controller software
number shall be displayed when
Pn
parameter is chosen.
2.4.3 configuration of devices;
Adjustment of other devices is executed similar to the signal device adjustment.
Each device has individual menu items, shown in device Operation Manual.
Configuration of different devices can be carried out simultaneously with several
signaling devices in the line; SENS measuring system is capable for operation during con-
figuration. It is not acceptable to adjust the device (using certain signal device) that is al-
ready being adjusted or interrogated by other signal device in the same time.
Warning! If 0 address is used for configuration, only one device can be con-
nected to the signaling device, otherwise other devices can be reprogrammed by
accident (this can affect address and other settings), i.e. only two devices with ad-
dress shall be in the line - the signaling device and a device with unknown address.
2.4.4 INDICATION OF ERRORS
In case of any extraordinary event occurrence (missing connection, unknown pa-
rameter receiving, etc) signal device informs the operator and displays the errors on the
screen. Possible mistakes and their reasons are pointed in table 2.4.
Table 2.4
Indication
Cause
Er.tr
No connection with device (line break, device failure).
Err
The transducer cannot measure set for viewing (transducer failure).
EPrr
The device returned parameter that is unknown for signal device (a new
device was applied in the system, outdated version of controller soft-
ware).
EE
Displayed instead of address set for viewing if address value is more
than 99
3 MAINTENANCE
3.1 Technical maintenance includes preventive and operation check works. Tech-
nical maintenance is performed in order to ensure operational capability and save trans-
ducer operation and technical features within its full lifetime.
3.2 It is necessary to follow maintenance instructions specified in cl. 3.1.
3.3 Preventive measures include:
Inspection and check-up of exterior. It includes checking of mechanical damages
absence, marking integrity, strength of signal device parts, absence of signal device sur-
face contaminations.
