2.1 Basic counting principles
2 Introduction
The ZK810 is a counting scale indicator which, when attached to a BSQ digital scale
base, creates a 35,000 division counting system. The indicator, shown in Figure 2.1, is
easy to use. The indicator has an Ethernet port and two RS232 ports.
See the Specification literature for a full list of specifications.
Figure 2.1 ZK810 front panel
2.1 Basic counting principles
There are several things which affect counting accuracy:
lenvironmental noise (vibration, wind, etc.)
lnumber of sample parts used
lthe weight consistency of the sample parts
lthe weight of one part
laccuracy requirement
Changes in each, or any one, of these variables can affect the accuracy for the better
or for the worse. If there is wind or vibration accuracy will drop, especially if parts are
small in weight. If parts are not a consistent weight, accuracy can be poorer but may
be increased by using a large sample size.
Accuracy with this system can be extremely high, even with small parts, if the
environment is controlled, parts have a consistent weight and a large enough sample
size is used.

2.3 Powering up the ZK810
2.2.1 Annunciators
The annunciators on the display are shown and labeled in Figure 2.2.
Figure 2.2 Annunciators
The triangular annunciators will light during operation to inform the user of the weighing
mode, active unit of measure, etc.
2.3 Powering up the ZK810
The ZK810/BSQ comes with a base mounted AC power supply unit (PSU) connected
to the back of the BSQ. This supplies the required input power of 12 to 36 VDC @
250ma minimum and is connected to a properly grounded outlet (100 VAC - 240 VAC,
50 or 60 Hz). The indicator is always ON as long as power is received. See Base
mounted AC PSU on page 13.
If using the optional rechargeable battery pack mounted on the rear of the base you
can expect approximately 20 hours of operation between charges. Recharge time is
four hours using the in-line PSU. The battery pack requires 24 to 36V to charge. See
Battery power on page 14 for more information. The battery timer setting can be used
to turn the indicator display OFF automatically.
You can also power the indicator with a 12 to 36 VDC power supply (250ma minimum
at 24VDC) via a 2.1mm center positive barrel jack plugged into the receiver on the back
of the indicator.
The first time you power up the ZK810 you need to pick which application you will be
using. See First time power up on page 16 for instructions on how to do this.

Introduction
2.4 Connections on the BSQ
The BSQ comes with two different back panels, depending on the power option you
choose. One is for AC power only and the other is for use with the optional battery pack
or AC power. These two panels and their connections are shown in Figure 2.3.

2.4 Connections on the BSQ
Base mounted AC PSU
On the Base mount model the AC power supply unit (PSU) is attached by a bracket to
the back of the scale base. The DC output barrel jack plugs into the 12-36 VDC input
as shown in Figure 2.4.
Figure 2.4 AC power block
Plug the power cord into a properly grounded outlet, then into the receptacle in the
PSU. See Figure 2.5.

Introduction
Battery power
The optional battery pack connects to the two battery connections as shown in Figure
2.6. The battery provides approximately 20 hours of operation before charging is
necessary.
Figure 2.6 Battery pack connections
When a 24-36 VDC power supply is plugged into the power connection on the back
panel of the ZK810, the green POWER light will turn on indicating power has been
applied to the BSQ base. The red CHARGING light will blink to indicate the battery is
charging. When the battery is fully charged the red CHARGING light will go out and the
power supply can be unplugged to work on battery power only.
The standby power button, pointed out in Figure 2.6, can be used to turn the ZK810
indicator on or off.
2.5 Leveling the scale
Place the scale on a level, stable surface free from vibrations or strong air currents.
Level the scale using adjustable feet and the bubble level located on the side of the
base. Turn the appropriate foot or feet until the bubble is centered and then lock the
feet in place by turning the locking collar snugly up against the scale body. See Figure
2.7.

2.6 Numeric entry procedure
The keys in Figure 2.8 have alternate functions in numeric entry screens.
Figure 2.8 Key function during numeric entry
In numeric entry screens, the center segments shown in Figure 2.8 flash. Use the keys,
as described in Figure 2.8, to enter a value on the display. Following is an example:
Example: To key in the number 507:
Repeatedly press the TARE()or SELECT()key until 5appears on the display.
Press the UNITS()key once to move cursor one space to the right.
Repeatedly press the TARE()or SELECT()key until 0appears on the display.
Press the UNITS()key once to move cursor one space to the right.
Repeatedly press the TARE()or SELECT()key until 7appears on the display.
Press the ZERO key to enter or accept the value.
Press the PRINT()key to move the entry function one digit to the left. This effectively
deletes the current value in that position and allows you to enter a new value in that
position.
2.7 Printing
There are four default ticket print formats that can be used. These are configured as
part of the setup by a qualified service technician. See examples below.

3.2.1 Sampling methods
Dribble sampling is the default sampling method. Bulk sampling is also available. This
is set in a password protected Supervisor menu. Each type is defined below.
Dribble sampling definition:
When sample parts are being added to the scale they can be counted out slowly or, in
other words, dribbled onto the scale. A key press (SAMPLE key) is needed to finish the
sampling process. The piece weight is calculated and the count is displayed.
Key functions in different applications may vary. These will be noted under each
application.

ZK810 Counting Scale User Instructions 17
3.2 Counting application
Bulk sampling definition:
When sample parts are being added to the scale they must all be placed on the scale
at once, in other words, in bulk. If the sample is large enough to meet the minimum
weight requirements the piece weight is calculated and the count is displayed with no
extra button presses.
3.2.2 SELECT key default function
In the Count application you can view the gross, net and count by repeatedly pressing
SELECT.

By default the sample size choices are 5, 10, 25, 50 or 100. When asked to add
samples, one of these will be the requested count. The smallest allowed sample size
is defined in the password protected Supervisor menu.
3.2.5 Counting in dribble mode
With the count application in dribble mode active, follow these steps to count:
1. Press ZERO to zero the scale, if necessary.
2. Use a tare method to tare a container, if necessary. See Net weighing on page

a. If the weight is stable, the display will show the correct number of parts
on the scale and the COUNT annunciator is lit.
b If the sample weight was not enough, PcE WtL will be displayed
briefly and then return to weight mode.
c If the weight was unstable, tMout is briefly displayed and the display
returns to gross weighing mode. The TARE key can be used to abort
the sampling process, if necessary.
If you do not place a sample on the scale within five minutes of selecting the sample
size, the display will show tmout (timeout) and return to the gross weight screen.
