Intended Use

As precise and robust weighing platforms, the ISBBS and ISDCS provide

reliable weighing results. The models are based on monolithic

technology (the principle of electromagnetic force compensation).

These industrial weighing platforms offer the following special features:

– Robust and durable Sartorius quality

– IP65 protection from dust and jets of water

– High-quality workmanship and materials

– Preload values can be deﬁned (for equipment installed on the scale)

Safety Precautions

Warnings and Safety Precautions

3 Read these operating instructions thoroughly before using the weighing

platform, in order to prevent damage to the equipment.

3 The weighing platforms comply with the European Council Directives as well as

international regulations and standards for electrical equipment, electromagnetic

compatibility, and the stipulated safety requirements.

3 Do not expose the equipment to aggressive chemical vapors or to unnecessarily

extreme temperatures, moisture, shocks, or vibration.

2 Avoid generating static electricity and connect equipotential bonding terminals.

3 All models meet the criteria for protection class IP65.

Any installation work that does not conform to the instructions in this manual

results in forfeiture of all claims under the manufacturer’s warranty.

3 If there is any indication that safe operation of the equipment is no longer

guaranteed, disconnect the platform from the power and ensure that it is not

used further.

3 Always ensure that the weighing platform is disconnected from AC power before

performing any maintenance, cleaning, or repair work.

3 Note the pin assignments when using cables provided by other manufacturers.

Check the connections of the cable against the corresponding cabling diagram

before connecting to the Sartorius equipment and disconnect any wires that are

assigned differently. The operator shall be solely responsible when using cables

not supplied by Sartorius.

3 The weight value can be affected by extreme electromagnetic inﬂuences.

Once the disturbance has ceased, the instrument can be used again in

accordance with its intended purpose.

ISBBS, ISDCS Operating Instructions 5

Getting Started

Warning:

3 Unpacked devices can lose their precision if subject to extreme vibrations.

Excessive vibrations may compromise the safety of the equipment. Do not

expose the equipment to unnecessarily extreme temperatures, moisture,

shocks, or vibrations.

Permitted storage temperature: -10°C to +40°C

Unpacking the Equipment

Remove the device from the packaging. Check for any visible damage. Save the

original packaging for any future transport. Unplug all connected cables before

packing the equipment.

Acclimatizing the Device

3 The device should only be opened by trained and qualiﬁed personnel.

Before opening the valve unit: Turn the main switch to “OFF." Take all steps

necessary to secure the equipment against unauthorized power-up.

Disconnect the device from the power supply if possible.

Once work is completed: Securely lock the valve unit.

Scope of Supply:

– Weighing platform

– Operating instructions

– Special accessories as listed on the bill of delivery, if ordered

6ISBBS, ISDCS Operating Instructions

Installation Instructions

t Set up a suitable installation location for the weighing platform.

The place of installation should be dry, level, and ﬂat. The operating temperature

ranges from -10°C to +40°C.

The weighing platform must not be subjected to unnecessarily extreme

temperatures, moisture, shocks, or vibrations that could result in damage.

Leveling the Weighing Platform

Purpose: – To compensate for uneven areas at the place of installation

– To ensure that the equipment is placed in a perfectly horizontal

position for consistently reproducible weighing results

Always level the weighing platform again any time after it has been moved to

a different location.

t Level the weighing platform using the four leveling feet. Turn the feet until

the air bubble is centered in the level indicator.

t Check to ensure that all leveling feet rest securely on the work surface.

y Each of the leveling feet must support an equal load.

y Adjusting the leveling feet:

To raise the weighing platform, extend the leveling feet (turn counterclockwise).

To lower the weighing platform, retract the leveling feet (turn clockwise).

Ground Conductor

The ground conductor is located underneath the weighing pan on the clamp

box or on the lower base of the weighing platform. It is marked as a ground

connection with the symbol shown here.

Grounding is implemented using a threaded bolt or screw terminal, or as a hole.

If a ground hole is the method of grounding, a stainless steel screw and nut

must be used. A lock washer should be placed underneath in order to prevent

the screw from loosening. The grounding cable must have a minimum cross-

section of 4 mm2 and must be ﬁtted with a suitable ring terminal. Connect

all equipment, including peripheral devices, to the equipotential bonding

conductor.

Data Interface

The weighing platform has a standard COM1 interface, RS-485 socket (IP65).

The standard COM1 interface can be converted to RS-232 through the

Sartorius Service Center.

Observe power supply instructions.

Operation as an RS485-interface:

Switch 4 must be open in order to switch to RS-485 operation (factory setting).

Where applicable, deactivate bias resistors for RS-485 operation. Open switches

for this purpose (factory setting).There must only be one instance of bias

resistors per transmission path (network orpoint-to-point connection). Otherwise

there is a risk of transmission errors. Where applicable, refer to the speciﬁcations

or circuit documentation for the remote station or network nodes in question.

Bias resistors must always be activated or deactivated in pairs. The terminating

resistor (transmitting side, switch 1 must be activated if the device is located at

either end of an RS-485 bus system, or where it is connected to another device

in a point-to-point link. There must also be a terminating resistor of 120 Ω in

place at the remote station. Where applicable, activate terminating resistor 120

Ω for RS-485operation:

Terminating resistor, receiving side 120 ΩSwitch 1 on

BIAS resistor, receiving side (RxD+, pull-up) 680 ΩSwitch 2 on
