Chapter 3 Operating Instructions and Maintenance
3 Operating Instructions and Maintenance
This chapter gives information that an operator will need to become familiar with the
scale and perform its functions in normal operating mode. Before weighing parcels, the
PS Scale should be configured properly and make sure power is applied as instructed
below. How the scale operates is based on the parameter settings in the set up
program. See Chap 2 for installation instructions and Chap 4 for advanced
programming of the set up parameters.
Power-up Sequence
To power up the scale, apply power to the unit:
o USB communication: Plug in USB cable to an energized PC.
o RS232 communication – Plug in power adapter to an AC outlet.
Note: Special software version
may be used for specific
applications
Note: Power supply is not needed for
U
SB connection to a PC since the
power requirements are within
standard USB specifications. If the
power supply is used with the USB,
the scale will recognize the power
adapter and use it as the power
source.
Note: On most models, the I/O button
is disabled and the scale is energized
w
henever power is applied to it, and
de-energized when power is removed.
The PS goes thr
ough a power-up sequence each time power is applied. The scale
performs a diagnostic test on its ROM and RAM, and then proceeds to the normal
operating mode. The power-up sequence is as follows:
1. All segments of the display characters are activated. This verifies operation of all
display segments.
2. The scale displays the software part number followed by the software revision
status. Software numbers for the standard PS models are:
Model SW Number
PS15 170700
PS30 170640
PS3L 170640
PS60 170702
PS6L 170702
PS90 174509
3. The scale then captures zero (if the zero reading is within 10% calibrated
capacity on power-up) and is ready for normal operation.
To turn off the scale, unplug the power source to the scale:
o USB communication: unplug the USB cable (and power adapter if used).
o RS232 communication – unplug the power adapter from AC outlet.
