2 Safety Information
The ECB has been tested for the applications and intended purposes documented in this operating
instructions. However, this does not absolve you from the responsibility of performing your own tests
of the product supplied by METTLER TOLEDO regarding its suitability for the methods and purposes
you intend to use it for. You should therefore observe the safety measures for your protection and for
operation.
2.1 Definition of signal warnings and symbols
Safety notes are marked with signal words and warning symbols. These show safety issues and
warnings. Ignoring the safety notes may lead to personal injury, damage to the instrument,
malfunctions and false results.

2.2 Intended use
The ECB is a control box which is used together with a METTLER TOLEDO thermostat. It supports
analog third-party sensors and enables volumetric and gravimetric dosing.
Always operate and use your device in accordance with the instructions contained in this manual. Do
only use it together with equipment specified in this documentation.
Any other type of use and operation beyond the limits of technical specifications without the written
consent from Mettler-Toledo GmbH, is considered as not intended.
2.3 Product specific safety
WARNING
Control of valves
Implement suitable measures if you use valves which are not supplied by METTLER
TOLEDO! If electromagnets are attached, the output circuits of the valve outputs can start
to oscillate. The valves then remain open which could lead to a hazardous situation
with certain applications.
− Do connect a resistor-capacitor element next to the valve.
ð Use the schematics below on how to connect a resistor-capacitor element (RC
element).
Safety Information 5ECB

7 SmartConnect Sensor ports
The sensor ports are used to connect third-party analog sensors to the ECB. The ECB has four sensor
ports. The following signals can be read by the ECB:
• Temperature (Pt100)
• Current (mA)
• Voltage (V)
Ready-to-use cables are available. Technical aspects such as configuration and soldering of the
cables are described in the SmartConnect Cables User Manual (30260711).

WARNING
Default data for Leo3 / EV-120 cable (order no.: 30254779)
The default data for LEO or EV-120 cable is based on a 300 bar sensor. Reconfigure
your cable if needed, see [Adjust pressure sensors}11].
1 If you use a pressure sensor with different limits, please reconfigure your cable
according to the pressure range.
2 Check if the value on the touchscreen and the sensor are the same, if not recon-
figure the cable.
7.1 Connecting cable to SmartConnect port
Note: There are dedicated ports for sensors (blue) and final control elements (green). Make sure the
color of the cable plug corresponds with the color of the port.
1 To fit the plug into the socket, the arrow on the plug needs to be at the top.
2 The status LED (only available on ECB) turns green once the sensor or final control element is
ready to use.
7.2 Adjust pressure sensors
The default values for pressure sensors are based on a 300 bar sensor. This means connecting a
LEO3, 300 bar will not need any adjustment. For other sensors do the following:
§ Sensor must be connected to cable that will be configured.
1 Tap on main screen.
SmartConnect Sensor ports 11ECB
2 Tap on *ECB.
3 Tap on the SmartConnect sensor port where the pressure sensor is connected.
4 Tap on Adjust sensor to reconfigure your pressure sensor.
5 For the Measured Value enter the lower limit of the measuring range (current) e.g. 4.00 mA. For
the Reference Value enter the pressure value that corresponds with the lower limit e.g. 0.00 bar.
6 Tap Next.
7 For the Measured Value enter the upper limit of the measuring range (current) e.g. 20.00 mA.
For the Reference Value enter the pressure value that corresponds with the upper limit e.g. 4.00
bar.
8 Tap Apply to save the data.
ð The pressure value is now visible on the touchscreen.

8 pH Module
Mount the pH Module
It is possible to use SevenExcellence™ pH/mV module (30034472) or SevenExcellence™ pH/Ion
(30034471). The modules must be ordered separately. ECB is delivered with two blank modules.
Note: Only analog pH electrodes can be connected.
To install the SevenExcellence™ pH modules proceed as follows:
§ Make sure the ECB is not powered at the time a
SevenExcellence pH module is added or
removed.
1 Loosen the screw on the plate on the rear of the
ECB until you can slide down the plate.
2 Remove the blank module.
3 Insert the SevenExcellence™ pH/mV or Seven-
Excellence™ pH/Ion module.
4 Slide the plate up and tighten the screw on the
plate back .
5 Switch the main device back on.
ð The ECB can now measure pH. NOTICEA pH
value is displayed even if no pH probe is
connected.
Adjust a pH sensor
pH sensors connected to the ECB can be adjusted with a 2-point adjustment.
§ 2 Buffer solutions at room temperature (25°C) are needed: Choose the pH range according to
your experiment.
1 Tap on pH on the main screen.
pH Module 13ECB
2 Tap on Adjust sensor.
3 Place the probe into the first buffer solution with the low pH.
4 Confirm the message on the touchscreen by tapping ok.
5 If necessary correct the Buffer solution pH value so it corresponds to the value of the buffer
solution the sensor is in.
6 Wait until the value Measured pH is stable and tap Apply.
7 Take out the pH sensor from the first buffer solution and clean the sensor carefully.
8 Place the sensor into the second buffer solution with the higher pH.
9 Confirm the message on the touchscreen by tapping ok.
10 If necessary correct Buffer solution pH value so it corresponds to the value of the buffer solution
the sensor is in.
11 Wait until the value Measured pH is stable and tap Apply.
ð The 2-point adjustment is finished.
Measure pH with the main device
Note Temperature compensation for pH is per default done with Tr. If there is no Tr available, Tj will
be used. Values from temperature probes integrated into the pH sensor are not considered for the
calculation of pH.
− Connect an analog pH sensor to the BNC port of the SevenExcellence™ pH module.
ð pH is displayed on the touchscreen of the connected main device.

9 Gravimetric Dosing
Gravimetric dosing refers to a technique where the dosing pump is controlled based on a balance
signal. The amount to be dosed can be specified in grams.
Supported pumps for gravimetric dosing
Support for any third-party dosing pump with analog control interface for:
• Current (0…20 mA)
• Voltage (-10…10 V)
• Frequency (0…3 Hz)

RS232 cable for syringe
pumps
Volumetric dosing refers to a technique where a syringe pump is used. The amount to be dosed can
be specified in milliliters.
Supported pumps for volumetric dosing
Support for selected KDS/Harvard syringe pumps with 9 or 15 pin TTL interface.
For some syringe pumps there are ready-to-use cables. See list below:
If only one dosing is connected to the main device it will be displayed automatically.
§ A supported syringe pump is available and prepared.
§ ECB is connected to main device.
− Connect the pump to a control port on the ECB with a control cable.
ð The dosing is now available on the touchscreen of the main device.
Volumetric dosing on the main device
Note: Syringe pumps are controlled through a so-called TTL (Transistor to Transistor Logic). The ECB
can only trigger the start and stop of a pre-programmed ramp on the syringe pump. The dosing is
controlled by the syringe pump. To capture the dosed amount you have to enter the same rate on the
ECB (see step 3). The captured amount may not be fully accurate so if necessary correct it in the
experiment data in iControl.
§ A supported and pre-programmed syringe pump is connected.
1 Tap Dosing on the main screen.
ð All connected Dosing Units and the ECB are displayed.
2 Select the syringe pump that you have prepared.
