2.1.2 Personnel Qualifications
All sequences implemented on WAGO-I/O-SYSTEM 750 devices may only be
carried out by electrical specialists with sufficient knowledge in automation. The
specialists must be familiar with the current norms and guidelines for the devices
and automated environments.
All changes to the coupler or controller should always be carried out by qualified
personnel with sufficient skills in PLC programming.

2.1.3 Use of the WAGO-I/O-SYSTEM 750 in Compliance with
Underlying Provisions
Fieldbus couplers, fieldbus controllers and I/O modules found in the modular
WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and
transmit them to actuators or higher-level control systems. Using programmable
controllers, the signals can also be (pre-) processed.
The devices have been developed for use in an environment that meets the IP20
protection class criteria. Protection against finger injury and solid impurities up to
12.5 mm diameter is assured; protection against water damage is not ensured.
Unless otherwise specified, operation of the devices in wet and dusty
environments is prohibited.
Operating the WAGO-I/O-SYSTEM 750 devices in home applications without
further measures is only permitted if they meet the emission limits (emissions of
interference) according to EN 61000-6-3. You will find the relevant information
in the section “Device Description” > “Standards and Guidelines” in the manual
for the used fieldbus coupler/controller.
Appropriate housing (per 2014/34/EU) is required when operating the WAGO-
I/O-SYSTEM 750 in hazardous environments. Please note that a prototype test

The devices to be supplied ex works are equipped with hardware and software
configurations, which meet the individual application requirements. WAGO
Kontakttechnik GmbH & Co. KG will be exempted from any liability in case of
changes in hardware or software as well as to non-compliant usage of devices.
Please send your request for modified and new hardware or software
configurations directly to WAGO Kontakttechnik GmbH & Co. KG.

The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for handling
devices/modules.

The counter module 750-633 (Up/Down Counter Ex i) receives the binary signals
from Namur sensors operating in hazardous environments of Zones 0 and 1.
The counter module supports 4 operation modes:
- Operation mode 1: Up-counter with enable input
- Operation mode 2: Up/down counter
- Operation mode 3: Frequency counter with enable input
- Operation mode 4: Peek time counter
The operation mode can be selected via the configuration and commissioning tool
WAGO-I/O-CHECK.

The counter is capable of counting binary pulses at the CLK input (clock).
Counting is edge-triggered, i.e. if clock signal changes from I < 1.2 mA to
I > 2.1 mA, the counter value will be incremented.
Using the operation modes “Counter with Enable Input” the U/D(GATE) input
enables counting. If the input is set (I > 2.1 mA), counting is enabled, if the input
is reset (I < 1.2 mA), counting is disabled.
Using operation mode “Up/Down Counter” the U/D(GATE) input determines the
counting direction. If the input is set (I > 2.1 mA), the counter counts up, if the
input is reset (I < 1.2 mA), the counter counts down. The counter can be set or
reset with the control byte.
The digital output DO is activated directly via the control byte or depending on a
pre-defined the counter value. The output is short-circuit-protected.
