WARNING
1- Don’t put signal cables near power cables
2- Connect shields only where indicated on diagrams
3- Connect ground as specified by standars
4- Never use a Megger to verify connections
3.3 USING THE SENSING
When the distance of load cell and/or cells are more than 60m use a shielded cable
2x1.5mm, connected to 13(+) and 16(-) terminal blocks (see Dwg ST11-100P/F/04).
Sensing function is used to feed back the power supply to maintain the load cell(s)
voltage equal to the desired value even in case of high cable impedance.
If the sensing has to be used, S1 and S2 jumpers on Mother board must be opened.
3.4 SUPPLY VOLTAGE
The MINI is a dual voltage instrument 115VAC or 230VAC
To select the appropiate voltage (Mod.11-100F) by the voltage selector mounted near
the main switch (see pag.7A).
(Mof.11-100P) the voltage selector (INT2) is on the AC BOARD internal instrument.
Before powering on the instrument, check if the power supply you are using is
appropiate.
Verify electrical connections and particulary check that no conductors at high tension
have been connected to terminals or signal connectors.
3.5 CLEANING INSTRUMENT INSTRUCTIONS
Conclude the instrument installation and wiring, clean residuals of rubber or wire. Is not
necessary other particulary cleaning because the instrument MOD.11-100F have
protection IP65.
IF THE INSTRUMENT IS NOT INSTALLED AND CONNECTED IN COMPLIANCE
WITH THE INDICATIONS OF THIS MANUAL, RAMSEY DOES NOT ASSUME
RESPONSABILITY ABOUT THE INSTRUMENT.
4. SET UP OF SCALE PARAMETERS
4.1 GENERAL
If no specific application has been requested, the instrument will be supplie with
following data :
Scale capacity 300.0 kg
Measure unit kg
Resolution 0.1 kg
If a specific application has been requested besides this manual, our Technical
Department will deliver a documentation containing all the specific data of your scale.
4.2 SET UP
WARNING : press RUN to cancel each wrong selection
At the end of each selection push [RUN] to come back to normal running. There are
three ways to access to parameters of MINI instruments :
a) With the function key [SET UP], to modify all data of the instrument general set up.
b) With the function key [CAL] for calibrations.
c) With the function key [SET POINT], to insert the parameters of the thresholds.
The drawing in the following pages show how to enter numeric data.
