Supply Specifications
Mode of Operation
4-digit 7-segment LED dis-
play used to monitor analog
signals, counter values or
time of the day.
The display value is freely
scaleable within the range
-9999 to +9999 with select-
able position of the decimal
point. Values from 3 1/2-digit
BCD, 4-digit BCD and 8-bit
binary transmitters can be
displayed, since the trans-
mission protocol is select-
able.
4 limit outputs are available:
HI, LO -relay outputs
HIHI, LOLO -NPN transis-
tor outputs
Each output can be allocated
freely to any scaled display
value. The limit outputs turn
on whenever the value con-
trolling the outputs is equal
or above the limit value
setting for HI and HIHI (equal
or below for LO and LOLO).
It is selectable whether the
limit outputs shall be reset
automatically (by the value
controlling the limit outputs
returning to normal) or
manually by activation of the
"Limit Reset" - input. The limit
outputs may also be disabled
if this feature is not required.
4 LEDs at the front also
indicate the signal level com-
pared to the 4 limit settings,
blinking upon limit alarm,
steady state after a manual
reset. The display can be
used in normal mode as well
as in multiplex mode (3 1/2-
digit BCD protocol only).
When used in multiplex
mode, the multiplex address
for the display may be
selected by a selector switch
(e.g. on the cabinet door) that
connects to the "Multiplex
Address" inputs. Each of the
display values from the 16
multiplex addresses can be
scaled individually. The limit
value setting however will
always refer to the multiplex
address defined during the
configuration.
With the 4 keys at the front
the display shifts to program
mode, in which scaling,
decimal point position, limit
value settings, channel ad-
dress, multiplex address etc.
is configured.

refer to the "User Manual"
delivered with the unit.
