ZERO: references the display to zero
TARE: the first press of t his key tares the display the second press clears the tare. A symbol in the far left of
the display indicates if a tare is present.
MODE: allows access for preset tare input.
PRI NT: initiates a printout if option fitted. The printout is selectable for nett or gross/ nett/ tare and for units
and linefeeds. A time and date print will also occur if installed. Note the printout will only occur when the
unit is steady and further printouts are inhibited until the load is removed.
POWER: used to switch on the unit, if this key is pressed when the unit is working the display will indicate
the supply voltage, this is useful for battery operation.

and further components added will be counted. The ZERO or TARE may be used if required. To return to
weigh mode press the MODE key.
PRI NT: initiates a printout of weight or count depending on mode selection.
Note the sample quantity is default to 10 however if you wish too alter this value press the POWER key and
input the desired quantity (1 to 100).
3. SI LO MODE
This mode inhibits inadvertent zero selection. To zero the display press the ZERO and then MODE key
toget her. Release the ZERO key and then the MODE key
4. PEAK HOLD
To select peak hold mode press the MODE key. Peak weight will then be displayed until the MODE key is
pressed again, the unit will then return to normal weighing.
The PRINT key initiates a printout of weight or peak weight depending on the mode.
Press POWER to view supply voltage.
5. TOTALI SI NG
Press the PRI NT key to add an indicated weight value to the store. Further additions are inhibited until the

7. RELAY FUNCTI ONS
The unit may be user configured for several relay options.
Ensure that the necessary hardware options are installed i.e. 1 or 2 relays. The relays are solid state
devices. These relays are rated at a maximum of 100mA at 24vdc. Connections to the relays are via
terminal connections close to t he devices designated 1 & 2 = relay 1 contacts 3 & 4 = relay 2 contacts.
These relays are volt-free contacts unless specified
Three modes of relay control are selectable along with 3 patterns of operation as detailed.
a. Standard Batcher (MENU> WEI GHMODE<code 4: [4000x] )
This allows a batching sequence utilising a single relay control.
Press the MODE key the display will briefly prompt TRIP1” and then the existing value will be shown. To
clear existing data first press the ZERO key to clear the value, the far left digit will show “E” indicating that
the display is in keyboard mode. Press the PRI NT key to increment the least significant digit and press the
TARE key to shift the digit to the left i.e. to input a value of 4000 press the PRI NT key 4 times and then
press the TARE key 3 times.
Repeat the above if Trip 2 is installed.
Ensure that the indicator shows zero by selecting the ZERO or TARE key.
Press the PRINT key to initiate the sequence.
The relay will close and remain closed until the target is reached. I f a tare is selected this will be cancelled,
further batching is inhibited until the display indicates zero. Use of the TARE key to zero the display is
intended for silo batching operations from a loaded silo.
b. One trip bat cher m ode ( MENU> WEI GHMODE<code 5 – AUTOMATI C: [5000x]) .
This mode controls a single relay continuously.
c. Tw o trip bat cher m ode ( MENU> WEI GHMODE<code 6 – AUTOMATI C: [6000x]) .
This mode controls two relays continuously.
