Status display
After switching on or resetting the VI… interface, the firmware checksum is initially checked. If
an error in the firmware is detected, the display shows permanently SE (Signature Error).
Otherwise, the firmware version of the interface is displayed. This is shown in form of three
numbers displayed in sequence, e. g. 4 – 2 – 3 represents version 4.2.3.
If no sensor has been configured yet, the display will show 99 continually. If, however, sensors
have been configured, for each and every configured terminal of the VP-… isolating amplifier,
first the terminal number and then the type of sensor represented by a symbol will be dis-
played one after the other (see following table):
o=
VISY-Stick fitted in the tank
b=
VISY-Stick/Reed Interstitial (monitoring of the intermediate chamber in double-walled
tanks)
c=
VISY-Stick/Reed Sump (monitoring of the manhole)
d=
VISY-Stick/Reed Sump (monitoring of the dispenser sump)
P=
VPS pressure sensor
S=
VISY-Sludge
T=
VISY-Stick Temp (temperature measurement with up to 31 temperature sensors)
(=
VIMS Tank (monitoring of the intermediate chamber in double-walled tanks)
l=
VIMS Product Pipe (monitoring of intermediate chamber in double-walled product pipes)
)=
VIMS Delivery Pipe (monitoring intermediate chamber in double-walled filling pipes)
%=
VISY-Input
&=
VISY-Output
Table 3: Sensor symbols
VIMS sensors cannot be operated with the VISY-Command RF.
Finally, the status of the various sensors is displayed in the form of a number (see below).

Status messages
As soon as configuration has been completed with the VISY-Setup, you can monitor the
operation of the sensors using the status display on the VI-4 interface. The display consecu-
tively shows the terminal number of a particular sensor, a symbol and the associated status
(e. g.
„
S
o=
O
“
means
“
VP board terminal no. 5 with VISY-Stick under operation
”
). In this case,
one sensor after another is then scanned in an endless loop.
