External control output
11 functions can be selected from the following:
OFF, Stable, Zero band, Full, Coarse low, Middle low, Fine low, Over, OK,
Under, Mixture, Discharge (between the discharge gates), Finish weighing, Fi-
nish low, Finish mixture, Nozzle descent, During weighing, Measurement se-
quence error, Abnormal weight, Error, During tare weight cancellation, Center
zero, Display gross weight, Display net weight, During hold, Servo error
2-pin method serial interface
2-pin method serial interface
Baud rate: 600 bps
Data bit length: 8 bit
Parity bit: Odd
Stop bit: 1 bit
Start bit: 1 bit
Communication data: Binary code (BCD)
The internal circuit is insulated by optocoupler.
External control input and common are connected.
Standard RS-485 interface
Baud rate: Can be selected from 1 200, 2 400, 4 800, 9 600, 19 200 and 38
400 bps
Data bit length: Can be selected from 7 bit and 8 bit
Parity bit: Can be selected from none, even and odd
Stop bit: Can be selected from 1 bit and 2 bit
Terminator: Can be selected from CR+LF and CR
Communication method: Half duplex
Synchronization method: Start-stop synchronous method
Address: Select from 0 to 31
Communication data: ASCII code
Cable length: Approx. 1 km
Connectable units: 32 units maximum
Termination resistance: External
Data transmission mode: Select from command mode and stream mode
Internal circuit and common are connected.
Servo control interface
Output
Command pulse
Input
Encoder pulse, Alarm signal, Emergency stop signal, OPEN side limit signal,
CLOSE side limit signal, Ready signal, Original point sensor signal
BCD output (optional)
Output
BCD 8-digit parallel output: With polarity (POL.) (output ON when negative,
output OFF when positive); P.C.(Print command): Turn on after conversion of
BCD output is completed during ixed time; Decimal point ERROR ON when
various errors occur; OVER, STABLE, Gross weight: ON when BCD output is
gross weight
Open collector output VCE = DC35 V, IC = DC40 mA MAX
The output is not updated, except in weighing mode. Input HOLD for BCD
output. BCD-ENABLE compulsory OFF for output related to BCD (high impe-
dance)
The above level input items are valid at a bridge input of 100 ms or more.
