SCT-1100 Weight Transmitter
Operation
Once turned on, the secondary instrument is available to connect to a primary instrument. The message
displays, in which
is the number of the primary instrument to be detected. When at least one primary instrument
is detected, the secondary instrument places itself on the one with the lowest RS-485 address.

and then the sum of the net weight
on all the scales displays. The
message displays about every 10 seconds.
- The reference unit of measure is that of the connected primary instrument with the lowest address. If
the other weights have different units of measure, they are automatically converted.
- If the sum of the weights is greater than 999999 the segments in the upper part of the display are
turned on.
- If the sum of the weights is less than -999999 the segments in the lower part of the display are turned
on.
- If the sum of the weights is not valid, because one or more primary instruments is underloaded or
overloaded, the segments in the central part of the display are turned on.
• Press
twice on the secondary instrument to produce a menu:
-
– allows for quickly selecting a primary instrument (displays only if more than one primary)
-
– allows for input of a setpoint (only if there are functions linked to relays). If there are no
functions linked to relays, the fast primary instrument selection displays and a prompt to enter the
primary instrument number.
• Pressing

,
or on a primary instrument transmits that key’s functionality.
To use the weight repeater function at least one primary instrument in the system must be turned on. When the
secondary instrument is powered on it automatically places itself on the first powered on primary instrument with
the lowest RS-485 address. If all the instruments are off or if the radio signal does not reach the secondary
instrument, the
message displays, in which
is the address of the primary instrument with which the
secondary instrument is trying to communicate.
• If there are various primary instruments, it is not possible to transmit the functionality of the
key to the
active primary instrument.
• At least two primary instruments must have connection to carry out the sum function.
• It isn’t possible to transmit functionality of the
,
,
keys to the primary instruments, in sum mode.
• If connection with the primary instrument acting as a repeater is lost, the secondary instrument tries to
reconnect. If it cannot reconnect within a second, it connects with the next primary instrument.
• If the connection with a primary instrument in the sum mode is lost, the secondary instrument tries to
reconnect. If the reconnection is successful, it remains in the sum mode. If the reconnection is unsuccessful,
it passes to the repeater mode of the next primary instrument.
Turning Off the Primary and/or secondary instruments
When the secondary instrument displays the sum of the weights:
• Press and hold on the secondary instrument to turn it off.
• Press and hold on a primary instrument to turn off only that instrument. The secondary instrument
momentarily displays
in which
is the number of the primary instrument turned off. The secondary
instrument then displays the weight value transmitted by the next detected primary instrument.
When the secondary instrument displays the weight transmitted by a primary instrument:
• Press on the secondary instrument. The action is repeated on the active primary instrument.
• Press and hold on the secondary instrument until
displays. The active primary instrument powers
off. After the
message, the secondary instrument displays
, (
= the primary instrument
turned off). The weight of the next detected primary instrument displays. The secondary instrument can be
turned off by pressing and holding when the
message displays.
