PT200MI instruction manual 4
4. Data format
a) STATUS 1 : OL = overload, ST = stable, US = unstable
b) STATUS 2 : NT = net weight, GS = gross weight
c) WEIGHING DATA : A stream of eight bytes consisting of "0" to
"9", negative sign "-", positive sign "+",
space " " and decimal point.
d) UNIT : kg = kilogram, t = ton
5. Schematic diagram of the serial port.
2.5 HI/LO COMPARATOR/SETPOINT OUTPUT (OPTIONAL)
1. HI/LO output : HH, HI, LO or LL
2. Max. capacity : 80VDC, 300mA
2.6 BCD OUTPUT (OPTIONAL)
1. BCD output : Parallel BCD output
2. BCD output level : 5V TTL or open collector
2.7 ANALOGUE OUTPUT (2 OPTIONS)
1. Analogue output, voltage option : 0~5V
2. Analogue output, current option : 0~20mA/4~20mA
The excitation current specification will be reduced to 120mA if the 0~20mA/4~20mA output board is
used.
NOTE: An analogue option and the BCD option cannot be used together.
2.8 INPUT (BUILT-IN)
Input : IN1, IN2 or IN3
Input mode : Passive switch
Input contact time : 30 ms
2.9 Single Material Batching Option
This option requires a Hi/Lo setpoint option to be fitted.
This option requires factory configuration and must be ordered at the time of purchase of the PT200MI
and Hi/Lo option.
Settings for Final, Zero Band, Optional Preliminary, Preliminary, Free Fall.
Outputs for Zero Band, Optional Preliminary, Preliminary, Free Fall.
See 2.5 above for electrical characteristics.
