1.1 Front Panel Keypad and Annunciators
Figure 1-1 shows the UMC222 front panel. The UMC222 display consists of six seven-segment display digits.
Table 1-1 lists the front panel keys and their functions.
Figure 1-1. UMC222 Front Panel
Panel Key Function
ZERO Provides push-button auto zero (PAZ) over ±1.9% or 100% full scale capacity. Operates only in Gross
weighing mode. USA: rezeroes the scale if the gross weight is within the band of zero selected in the Set
Up Mode (2%, 5%, 20% or Full Scale). The Zero key will rezero the scale only in Gross mode.
OIML: rezeroes the scale if the gross weight is within the band of zero selected in the Setup mode (2%,
5%, 20% or Full Scale).
The Zero key will rezero the scale in either Net or Gross mode. If the scale is operating in the Net mode
and a valid Zero is executed, the unit will zero both the zero and tare values and returns the indicator to
Gross mode automatically.
MODE USA: Selects Net/Gross mode and recalls total or Average Piece Weight.
OIML: Selects the desired weight data to be viewed (Gross Recall or Total Recall). If the indicator is in the
Net mode, when the MODE key is pressed, the Net indicator LED is off and the recalled gross weight data
is momentarily displayed. The indicator will then automatically return to the Net display mode.
TARE Provides push-button tare entry over 100% of scale capacity. Pressing TARE key switches to net mode
and enters tare. USA – When issued in the Gross mode, the indicator will acquire the tare value and
automatically shift to the Net display mode.
OIML - When issued in the Gross mode, the indicator will acquire the tare value and automatically shift to
the Net Display mode if the Tare acquisition is > zero by (+1/2 grad). If a Tare is issued within ±1/2 grad of
zero, the indicator is set to Gross mode and the Tare value is set to zero (Tare = 0). If a Tare acquisition is
negative or the weight data is in motion, the indicator remains in the present mode and no tare is
performed.
UNIT If the indicator has been set up to perform conversions between the base unit and the selected
conversion unit, when this key is pressed the weight data is toggled between its calibrated base weight
unit (i.e. lb, kg,) and the conversion unit.
PRINT Provides a manual print function if the unit is wired to serial printer or other data device. See Section 8.4
on page 35 for serial output specifications. Issues a demand print command to the serial output. This key
also performs an accumulation of the current displayed weight data when the Totalizer mode is active.

Table 1-2 summarizes the front panel annunciator functions.
1.1.1 Gross/Tare/Net Weighing Operations
The UMC222 offers two methods of Gross/Tare/Net operations (Standard, European). By default the indicator is set
to operate Gross/Tare/Net data in the more familiar USA (std.) conventional format. The selection of Eur sets the
Gross/Tare/Net operation to operate per OIML requirements.
1.1.2 USA or Standard Operation
When the standard indicator is initially powered up the display automatically comes up in the last mode it was in
(Gross or Net mode) prior to a power down.
Annunciator Function
ZERO On when scale weight is within ±0.25 displayed graduations of zero. Used in gross or net weighing mode.
NET On when the indicator is in net weighing mode.
lb/kg lb or kg LED is lit to show the current displayed weight units.
MOTION On when scale is in motion.
TOTAL On when the display mode is recalling the accumulated weight data.

4 UMC222 Installation Manual
2.0 Installation and Wiring
This section describes the procedures for connecting load cell and serial communications cables to the UMC222
indicator. Instructions for battery and CPU board replacement are included, along with assembly drawings and parts
list for the service technician.
Use a wrist strap to ground yourself
and protect components from
electrostatic discharge (ESD) when
working inside the indicator.
2.1 Unpacking and Assembly
All indicators are configured and tested prior to
shipment to ensure that they are fully functional.
Immediately after unpacking, visually inspect the
UMC222 to ensure all components are included and
undamaged. The shipping carton should contain the
indicator with attached tilt stand, this manual, and a
parts kit. If any parts were damaged in shipment, notify
Condec and the shipper immediately.
The parts kit contains the following items.
2.2 Enclosure Disassembly
The indicator enclosure must be opened to connect the
load cell and communications cables.
The UMC222 has no on/off switch.
Before opening the unit, ensure the
