Parameter Choices Description
OUt 1
OUt 2
OUt 3 OPEn
Normally Open: the relay is de-energized and the contact is open when the weight is
lower than the programmed setpoint value; it closes when the weight is higher than or
equal to the programmed setpoint value.
CLOSE *
Normally closed: the relay is energized and the contact is closed when the weight is
lower than the programmed setpoint value; it opens when the weight is higher than or
equal to the programmed setpoint value.

The contact will switch on the basis of weight, according to setpoints (see Section 2.12
“Setpoints Programming” on page 30) Select:
Gross (default) - the contact will switch on the basis of gross weight or
Net - the contact will switch on the basis of net weight (If the net function is not active,
the contact will switch on the basis of gross weight).
NOdbUS
The contact will not switch on the basis of weight, but is controlled by remote Modbus
protocol commands. (DeviceNet, Profibus, Ethernet Only)
dEunEt
The contact will not switch on the basis of weight, but is controlled by DeviceNet.
(DeviceNet Model Only)
PrOFI
The contact will not switch on the basis of weight, but is controlled by Profibus. (Profibus
Model Only)
EtHnEt
The contact will not switch on the basis of weight, but is controlled by Ethernet. (Ethernet
Model Only)
PLC
The contact will not switch on the basis of weight, but is controlled by remote protocol
commands. (Analog Only)
StAbLE
Relay switching occurs when the weight is stable.
SEt 1
SEt 2
SEt 3 POSnEG *
Relay switching occurs for both positive and negative weight values.
POS
Relay switching occurs for positive weight values only.
NEG
Relay switching occurs for negative weight values only.
SEt 1
SEt 2
SEt 3 OFF *
Relay switching will not occur if the setpoint value is ‘0’.
On
Setpoint = ’0’ and nodbus=posneg, relay switching occurs when the weight is ‘0’; the
relay will switch again when the weight is different from zero, taking hysteresis into
account (both for positive and for negative weights).
Setpoint = ’0’ and nodes=pos, relay switching occurs for a weight higher than or equal to
‘0’, the relay will switch again for values below ‘0’, taking hysteresis into account.
Setpoint = ’0’ and nodes=neg, relay switching occurs for a weight lower than or equal to
‘0’, the relay will switch again for values above ‘0’, taking hysteresis into account.

(In 2 default)
(NET/GROSS): by closing this input for less than one second, it performs a SEMI-
AUTOMATIC TARE and the display will show the net weight. To display the gross weight
again, hold the NET/GROSS input closed for 3 seconds.
2ErO *
(In 1 default)
By closing the input for less than one second, the weight is set to zero (see Section 3.3
“Semi-automatic Zero (Weight Zero-setting For Small Variations)” on page 33)
PEAH
With the input closed the maximum weight value reached remains on display. Opening
fthe input the current weight is displayed.
PLC
Closing the input no operation is performed, the input status may however be read
remotely by way of the communication protocol.
COntIn
Closing the input for less than one second the weight is transmitted via the serial
connection according to the fast continuous transmission protocol one time only (only if
contin is set in the item serial).
COEFF
When the input is closed the weight is displayed based on the set coefficient (see Section
2.1.7 “Display Coefficient” on page 16), otherwise the weight is displayed.
* - indicates default value.
