4. Warnings
4.1. General
• Indicator not to be subject to shock, excessive vibration or
extremes of temperature (before or after installation).
• Inputs are protected against electrical interference, but
excessive levels of electro-magnetic radiation and RFI may
affect the accuracy and stability.
• For full EMC or for RFI immunity, termination of cable shields
and correct earthing of the instrument is essential.
• Indicator and load cell cable are sensitive to excessive electrical
noise. Install well away from any power or switching circuits.
4.2. Configuration Issues
• Configuration and calibration can be performed from the front
panel, using digital setup. When Full Setup is used, all menu
items are accessible and care must be taken to ensure no
accidental changes are made to calibration and trade settings.
• Enter a passcode to prevent unauthorised or accidental
tampering. If the passcode is lost, the manufacturer should be
contacted for further advice.
5. Installation
The following steps are required to set up the R300 Series
indicators.
• Inspect indicator to ensure good condition.
• Use connection diagrams to wire up load cell, power and
auxiliary cables as required.
• Use the drill hole template provided for hole locations.
• Connect Power to indicator and press <POWER> key to turn the
instrument On.
• Refer to the Instrument Setup section page 18 for information on

5.1. Electrical Safety
• For your protection all mains electrical hardware must be rated
for environmental conditions of use.
• Pluggable equipment must be installed near an easily accessible
power socket outlet.
• To avoid the possibility of electric shock or damage to the
instrument, always switch off or isolate the instrument from the
power supply before maintenance is carried out.
5.2. R310/R320 Panel Mount Template
Use the R310/R320 panel mount template for drill hole locations.
The template indicates positions for the two 4mm mounting
screws through the panel. Also displayed on the template is the
position of the rectangular hole that should be cut to allow for the
connection of cables. The drilling template supplied with the
indicator allows for front or rear machining of the panel.
5.3. Special Function Key (R320 Only)
• The Special Function Key on the R320 ships as a blank key.
• If any of the special functions are to be used on the indicator it is
important that the matching function key overlay sticker
(supplied) is applied to the keypad.
• Ensure keypad is clean and dry before affixing sticker.

5.4. rin-LINK
The optional rin-LINK
cable can be used to
transfer setup and
calibration information
from a PC (eg. to be
stored for later use
and/or transferred to
other instruments). It
can also be used to
download software upgrades to the instrument from a PC.
• Attach the rin-LINK cable to the PC using the DB9 connector.
• Attach the rin-LINK head to the left side of the instrument display
using the permanent magnet located within the head of the rin-
LINK.
WARNING: The rin-LINK head contains a strong magnet and care
should be taken with its proximity to electronic media (eg. credit
cards, floppy disks, etc.) and/or other electronic instrumentation.
5.4.1. rin-LINK Activation
A long press of the <GROSS/NET> key will toggle the rin-LINK
infrared communications On/Off.
When the rin-LINK has been (enabled) the following will occur:
• The instrument briefly displays the prompt rin-L.
• The editing annunciators (ie. GRP, ITM, etc.) will flash for up to five
minutes while the instrument searches for activity. During this
period, the R320 also disables the RS-232 communications.
• Activity Located: If the instrument is successful in locating activity,
the editing annunciators will continue to flash during the entire period
of communications.
• No Activity Located: If the instrument fails to locate activity, the
rin-LINK will be disabled and the editing annunciators will stop
flashing. The R320 will also revert back to the normal RS-232
communications (ie. the SERIAL:TYPE setting will be re-activated).

6. Connections
6.1. Cable Connections
• All cable connections are made to the rear of the instrument
using screwless terminals.
• Wires must be stripped of insulation by at least 10mm.
• To install, depress the orange lever beside the terminal required
and push wire into the hole. Release the lever and pull gently on
the wire to ensure it is securely trapped in the terminal.
6.2. DC Power (DC PWR + , DC PWR –)
• The DC supply need not be regulated, provided that it is free of
excessive electrical noise and sudden transients.
• The instrument can be operated from a high quality plug-pack as
long as there is sufficient capacity to drive both it and the load
cells.
6.3. Load Cell Connection
The R300 Series units may be connected for either 4-wire or 6-
wire operation. For more information, refer to BUILD:CABLE
setting page 20.

Rinstrum - R300 Series Digital Indicator Quick Start Manual Rev 1.5
Page 10
6.3.1. 4-Wire Connection
The minimum connectivity requirements are the connection of
four wires (ie. Excitation + and – along with Signal + and –).
The BUILD:CABLE option must be set to 4 to allow for 4-wire
connection.
6.3.2. 6-Wire Connection
The excitation and signal lines are connected the same as for a
4-wire installation.
The BUILD:CABLE option must be set to 6 (the default) to allow
for 6-wire connection.

6.4.2. Printer Connections (RXD/TXD, GND and DTR)
RS-232 - R320 to Printer (DB25)
6.4.3. Remote Display (TXD, GND)
• Connect TXD to RXD and GND to GND on the remote display.

Rinstrum - R300 Series Digital Indicator Quick Start Manual Rev 1.5
Page 13
6.4.4. Remote Input
• The indicator requires a voltage free contact between TXD and
RXD to enable the remote input (ie. SPEC:REM.FN). Note:
The remote input will not function when in setup or when using
the rin-LINK.
WARNING
The remote input is a voltage
free contact (eg. button,
mechanical relay).
Connection of any active
circuitry may damage the
instrument.
6.4.5. Outputs
• Output drivers for the R320 are isolated open emitter transistor
drives that are capable of driving up to a total of 300mA.
• This configuration allows for the direct connection of the R320
outputs to most types of PLC.
• The voltage applied to the COM terminal appears on the output
lines (ie. OUT1 and OUT2) when the outputs are active (eg. to
connect to a PLC connect +24V to the common terminal). The
outputs can then be connected directly to PLC inputs so when
the outputs are active the PLC will see a 24V signal.
• To drive external loads (eg. relays), connect the relay coil
positive supply to the output common and the output line directly
to one side of the relay coil.
• Connect the other end of the relay coil to the negative supply. It
is recommended that fly-back diodes or transient suppressors be
fitted across relay coils to limit switching noise.

6.5. Connecting Shields
To obtain full EMC or for RFI immunity, cable shields MUST be
connected to the earth lug on the rear of the instrument.
This figure shows the connecting cables restrained using cable ties
fastened around the cable strain relief anchors.
6.5.1. Cable Shield Connection and Earthing
• Care should be taken when connecting shields to maximise
EMC or RFI immunity and minimise earth loops and cross-talk
(interference) between instruments.
• For full EMC or for RFI immunity, termination of the cable shields
at the earth lug is very important. The earth lug of the instrument
must be separately connected to ground potential via a reliable
link.
• The instrument should only be connected to earth via a single
reliable link to avoid earth loops.
• Where each instrument is separately earthed, interconnecting
cable shields should be connected at one end only.
• Caution: Some load cells connect the cable shield directly to the
load cell (and therefore the scale base). Connection of the load
cell cable shield in this situation may be site specific.

6.6. Regulatory Sealing Requirements
To comply with regulatory sealing requirements for each
instrument, (ie. to ensure instruments are not accidentally or
deliberately tampered with), it is important that proper sealing
procedures be adhered to.
6.6.1. R310 and R320 Sealing (R320 shown)
For the R310 and R320, affix sealing stickers to the rear of the
instrument, over one or more screws in the locations indicated.
