I/O PARAMETERS
The I/O parameters refer to the option settings for the indicator’s input and ou-
tput channels:
RELAYS | A relay is a switch, which means it can only be on or o. Its activation
may depend on a number of variables, which are the settings that can be
determined in these menus. The indicator can have up to 4 relays.
CURRENT LOOP | The current loop (4-20 mA) refers to the analogue
communication method used by the indicator to send weight information
according to industry standards.
The adjustable parameters for each of the four relays are the same:
Mode
0
O
1
On when weight is above X
2
On when weight is below X
3
Reserved
Duration
0
Time delay is o; the relay changes the status according to
the pervious setting (mode)
1 a 255
Relay time delay in milliseconds (150 equals 1,5 seconds)
Weight Activation weight for the relevant relay
The current loop refers to the amplitude of the current in milliamperes that cor-
responds to the weight scale allowed by the scale: the current loop ranges from
4 to 20 mA, making it possible to match the maximum and minimum of this cur-
rent with customizable weight values. The current transmitted by the equipment
will correspond to the weight according to this scale.
♦ Weight < 'MIN' programmed, the current will be below 4 mA (≈3.6 mA);
♦ Weight > 'MAX' programmed, the current will be above 20 mA (≈20.4
mA);
♦ Within the programmed margins, a linear value between 4 and 20 mA
will correspond to weight.
Current Loop
0
Deactivated
1
Activated when the weight is over X
2
Activated when the weight is under X
Minimun Weight Minimum weight value for sending weighing
Maximum Weight Minimum weight value for sending weighing
Gross Weight
0
"Weight" refers to net weight
1
"Weight" refers to gross weight
Fine tuning for:
- minimum level
- maximum level
It’s necessary to insert a reference value in the platform for
each level; afterwards, it’s possible to adjust the intended alte-
ration with the help of an ammeter connected to the indicator.
