2 Introduction
The ZP900 high performance post mail and shipping scales provides a choice of
indicator types and BSQ base sizes and capacities. For capacity choices refer to the
product literature. The BSQ base sizes available are:
l9 in x 12 in (230 mm x 305 mm) base
l12 in x 14 in (305 mm x 355 mm) base
The type of indicators available include:
lbase-mounted
ldesk-mounted
lpole-mounted display (single or dual display available)
The indicator comes standard with two RS232 COM ports and can be upgraded to
enable use of 2 USB HID ports and an Ethernet port. Refer to the product literature for
a description of the features, options and specifications.
Figure 2.1 ZP900 post scale series
When a base-mounted indicator is attached to the BSQ scale, be sure the feet are
adjusted so the indicator is not touching the desk/table, just the feet.

Introduction
2.1 Unpacking and installation
Unpack the scale and check for any damage. Report damage to the shipping company
immediately.
2.1.1 Removing the shipping stops
Four colored shippings stops are installed under the platter of the BSQ scale at the
factory. Before you begin weighing be sure to remove these stops. Refer to the
following photos.
Repeat these steps on all four corners. Save and re-use if shipping the scale becomes
necessary in the future.
2.1.2 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 2.2.
Figure 2.2 Foot and locking collar
Shipping stops shown taped in place.
Slide the stop down and
remove it from the slot. Keep
for future shipping.
Remove the tape and

2.2.1 Connections on the ZP900
The connections for the ZP900 indicator are shown in Figure 2.3.
Figure 2.3 ZP900 connections
The supplied RJ45 cable is used for connecting between the indicator and base. The
cable and receptacle connectors are keyed so that it will only fit into the ZP900
Quartzell Scale and BSQ Scale connectors. See the areas pointed out in Figure 2.3
and Figure 2.4.
Figure 2.4 Keyed RJ45 cable connector
If substituting this with a non-keyed RJ45 cable do not inadvertently connect between
the BSQ Scale and ZP900 Ethernet connectors as it may damage the internal ZP900
Ethernet port components.
The Desk mount ZP900 comes with the in-line PSU which can be connected to either
the ZP900 or the BSQ power input connector. Power is supplied to the other device
through the RJ45 interface cable.

2.2.2 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 2.5.

2.2 Connections
Base mount
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 2.6.
Figure 2.6 AC power block
Plug the power cord into a properly grounded outlet, then into the receptacle in the
PSU. See Figure 2.7.

Introduction
Battery power
The optional battery pack connects to the two battery connections as shown in Figure
2.8. The battery provides approximately 20 hours of operation for a single display and
15 hours for a dual display system before charging is necessary.
Figure 2.8 Battery pack connections
When a 24-36 VDC power supply is plugged into the power connection on the back
panel of the ZP900, 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 2.8, can be used to turn the ZP900
indicator on or off.
2.3 Powering up the ZP900
The indicator requires input power of 12 to 36 VDC @ 200ma min. The indicator is
always ON as long as power is received. If using the ZP900 rechargeable battery pack,
the battery timer setting can be used to turn the Indicator display OFF automatically.
Power can be supplied by:
lThe included AC to 24VDC in-line PSU connected to a properly grounded
outlet (100 VAC - 240 VAC, 50 or 60 Hz)
lOptional rechargeable battery pack mounted on the rear of the base. 20
hours operation between charges. Recharge time is four hours using the in-
line PSU. The battery pack requires 24 to 36V to charge.

3.1 Initial power up
3 General operation
When power is cycled or when exiting from a menu the message PoSt is displayed
briefly.
3.1 Initial power up
3.1.1 Power up zero
On power up or when exiting from any menu with SAVEYES selected, the scale must
be within the Power Up Zero window (default is +/- 10%) or a message Z-Error is
displayed. Remove the weight causing the error and when stable the display should
show Zero weight and be ready for normal operation. If the scale will not capture zero
then it may need to be calibrated. Refer to the Service manual or contact the scale
provider if needed.
3.1.2 Power up gravity
If the Power Up Gravity setting was previously enabled the display will prompt with the
message grAVitY.
Press the ZERO key and the previous setting for the calibration gravity value will be
displayed. This value can be accepted by pressing the ZERO key or enter a new value
to match the installation site location. Use the Numeric entry procedure on page 17.
The scale should then perform as though calibrated at the installation location. Press
F1 to bypass Gravity entry but this process will be repeated on the next power up until
a value is accepted. Refer to local area Gravitational constants or contact the scale
provider if needed.
3.2 ZERO key
The ZERO key can be used to re-capture zero if the weight is stable and inside the
allowable zero range (default is +/- 2%). If ZERO key is pressed when the weight is
unstable or outside the zero range the message cAnt is displayed.
3.3 F1 key
If a second unit of measure has been configured the F1 key will toggle the display
between the available units of measure. If the second unit of measure is not lb or kg
then the 3rd annunciator along the right side of the display will be illuminated when
active. The F1 key is also used for password entry to gain access to the ZP900
Configuration and Diagnostic Menu's. Refer to Accessing the menus on page 18.
CAUTION: Verify with local agencies if adjusting the gravity factor is accepted
in your area. It may be required that calibration be done with certified weights.
