2. General
These instructions must be read in addition to the ZOK-Zx Instruction Manual (or
to the manual of the KOBOLD flowmeter, where the “ZOK-ExM” instrument is
mounted), if you have purchased an ATEX/IECEx intrinsically safe certified ZOK-
Ex series instrument and intend installing it in a hazardous environment for which
it is approved.
The intrinsically safe certified instrument may be stand alone (ZOK-Ex) or fitted to
a KOBOLD flowmeter with Ex-certified pulse sensor.
The instruction manuals on our website www.kobold.com are always for currently
manufactured version of our products. Due to technical changes, the instruction
manuals available online may not always correspond to the product version you
have purchased. If you need an instruction manual that corresponds to the
purchased product version, you can request it from us free of charge by email
([email protected]) in PDF format, specifying the relevant invoice number and
serial number. If you wish, the operating instructions can also be sent to you by
post in paper form against an applicable postage fee.
3. Conforming Standards
The intrinsically safe units DON-1A…5A/ZOK-Ex are certified in accordance with
the ATEX directive and IECEx scheme. Prior to installation, review the
certification marking on the instrument label to confirm if it is appropriately
certified for your region, suits the site classification and complies with your
hazardous area philosophy.
ATEX Directive
Complies with ATEX directive 2014/34/EC
Conforms to Standards: See certificate
Instruments have also been assessed against the Essential Health and Safety
requirements (ESHR’s) as defined in European Directive 2014/34/EU for
II 2G.
The instruments are certified for “ia” (intrinsically safe) protection suitable for gas
group IIB and temperature class T1 to T4 in an ambient temperature of -20 to +60
deg C and are suitable for installation in Group II, Zone 1 and 2 areas.
The instruments have also been tested to IEC60529 and comply with a protection
rating of IP66/67.

4. Overview
The certified ZOK-Ex series is an indicator providing a display of flowrate,
accumulated total and resettable total for potentially explosive areas. It can be
loop powered, battery powered and/or dc powered via an approved associated
apparatus such as an intrinsically safety barrier.
In addition, when externally powered the certified ZOK-Ex series (not ZOK-E1)
provides one or more outputs (depending on model and configuration).
Further options are:
 Dosing unit with one or two stage dosing using one or two opto-coupler
outputs with switching function (model ZOK-E2)
 Supply via 4-20 mA current loop proportional to the flow (model ZOK-E3)
The optional alarm and/or pulse outputs must be driven each by a separate
associated device:
 Low flow and high flow rate alarm (model ZOK-E5)
 Scaled pulse output for remote totalisation (model ZOK-E5)
Note: The background lighting is deactivated in all ZOK-Ex electronics.
5. Mechanical Installation (also refer to ZOK-Zx series Instruction
manual)
There are additional installation requirements to the Instruction Manual for
certified ZOK-Ex series instruments in accordance with the ESHR’s as defined in
annex II of the ATEX directive 2014/34/EU.
The ambient temperature must be within the limits -20 to +60 °C.
The electronic units must be installed in such a way that mechanical and thermal
stresses are avoided.
The instrument case is not considered to be an electrostatic risk; however,
the equipment must not be installed in a position where it may be subjected
to an excessive air flow or subjected to rubbing that may cause an
electrostatic build up. In addition, the instrument shall only be cleaned with
a damp cloth.
In all installation’s appropriate local rules, regulations and directives governing
instrument selection, installation practices and requirements must be followed.

ZOK-Ex
ZOK-Ex K08/0322 page 5
6. Electrical Installation
Power supply options:
Most units can be driven through 3 different power options. The software of the
ZOK-Ex units detects the power mode and enables / disables corresponding
hard- and software functions.
a. Battery powered (using intrinsically safe ATEX Battery-see Section 11):
No electrical outputs, only unpowered sensors can be used (e.g. reed
switch or certified induction coils). This power option can only be used with
ZOK-E1 and ZOK-E3).
b. External supply (operated by an intrinsically safe power supply). In
combination with an external supply, only passive 2-wire sensors (e.g.
reed switches, certified induction coils, or certified NAMUR sensor) or
certified 3-wire sensors, which are supplied by a separate safety barrier
and sensor signal is galvanically separated, can be used.
The electrical outputs 4-20 mA (3-wire, ZOK-E3) or Pulse output /
switching output (ZOK-E5) or switching outputs for the Dosage (ZOK-E2)
can be used here.
c. External loop powered 4-20mA (operated by intrinsically safe power
supply). Only certified two-wire sensors without auxiliary power can be
connected (reed switch as a simple device or certified induction coil). This
wiring option can be implemented with ZOK-E3 devices.
Input sensor options:
a. Unpowered inputs:
Reed switches are considered to be simple electrical equipment and can be used
in EX zone 1, provided that the manufacturer has issued a conformity
assessment or certification by a test authority. This applies to the reed switch
sensor of the DON electronics option -HA.

c. Sensors that require auxiliary power:
Examples of this type of sensor are 3-wire sensors, pre-amplified coils of turbine
knives or Namur proximity sensors. The voltage required to power the sensor
comes from the approved power supply and flows through the ZOK-Ex device.
These sensors must be certified and the input parameters of the sensor must not
be smaller than the unit parameters of the ZOK-Ex instrument:
Vi = 8.2 VDC, Ii = 100 mA, Pi = 0.7 W
The power supply of the ZOK-Ex instrument must come from a certified source
(commonly known as an isolating switch amplifier). The output parameters of the
amplifier must not be higher than those of the ZOK-Ex device:
Vi = 28 VDC, Ii = 100 mA, Pi = 0.7 W
Connection examples with the DON sensor options -HA/KA/GA/DA are shown in
section 12.
d. Other sensors:
Certified sensors that cannot be fed from the ZOK-Ex electronics can also be
connected to the ZOK-Ex devices. For this purpose, the corresponding sensor
must be supplied separately from an intrinsically safe power supply and the
sensor signal must be transferred to the ZOK-Ex electronics in an electrically
isolated manner (e.g. via an optocoupler output).
In this case, the same connection diagram is recommended as for 3-wire
sensors. (see c.)
Electrical outputs (only ZOK-E2/E3/E5):
The ZOK-Ex electronics (except ZOK-E1) are certified to provide different
output signals (analog, switching or pulse signal). In order to be able to use the
outputs, they must be operated with a separately constructed intrinsically safe
circuit.
In all cases, the output parameters of the associated power supply unit must not
exceed the input parameters of the ZOK-Ex electronics:
Vi = 28 VDC, Ii = 100 mA, Pi = 0.7 W

ZOK-Ex
page 8 ZOK-Ex K08/0322
1. 2-wire 4-20 mA current loop (ZOK-E3):
The ZOK-Ex electronics can be supplied by a two-wire 4-20 mA loop if the
input sensor does not require a power supply from the ZOK-Ex device (reed
switch or certified induction coil sensor).
Connection examples with certified safety barrier can be found in
section 12

ZOK-Ex
ZOK-Ex K08/0322 page 9
2. 3-wire 4-20 mA output (ZOK-E3):
The ZOK-Ex device can also be operated in a three-wire 4-20 mA
configuration.
Detailed connection examples with certified safety barrier can be found
in section 12
3. Dosing function / pulse or flow alarm (ZOK-E2 / E5):
In the case of ZOK-E2 / E5 devices, the electronic assembly is equipped with
an additional optocoupler board. This board offers 3 isolated passive
optocoupler outputs for low-flow / high-flow alarm outputs and pulse output.
In the ZOK-Ex versions, the standard connections for pulse and alarm outputs
are deactivated, the signals are only output via the optocoupler outputs. The
status output is not available for ZOK-Ex.

Note: All 3 outputs (4-20 mA, pulse and switching outputs) can be used
at the same time if a separate intrinsically safe circuit is set up for each
output signal with the aid of suitable certified safety barrier.
In addition to the wiring requirements of the ZOK-Ex operating instructions,
the appropriate local rules, regulations and guidelines for wiring practices for
intrinsically safe installations must be followed.
With regard to the cable selection and the permissible length, the associated
device capacitance and inductance parameters must not be exceeded by the
sum of the capacitances and the sum of the inductances within the loop.
When calculating the permissible cable length, use the capacitance and
inductance values of the ZOK-Ex from the Exi certificate.
Certain regions like Europe allow the inductance / resistance ratio of the cable
to be used instead of the sum of the inductances. In this case, the cable
inductance / resistance ratio must be lower than the maximum inductance /
resistance ratio permitted by the associated device.

7. Programming
Refer to ZOK-Zx instruction manual for programming, parameterization.
8. Service
The only replaceable item within the instrument is the EX battery pack and can be
replaced as a complete unit. Only the certified intrinsically safe battery assembly
ERS-BATEX036 may be used. This spare part can be ordered from the Kobold
sales offices.
9. Repair
The ZOK-Ex series instruments must only be repaired by trained personnel using
approved spares. Instruments requiring repair must therefore be returned to the
manufacturer.

Mounting the ATEX Battery
In case if the ATEX Battery is ordered separately, following steps need to be
taken to connect it:
1. The ATEX Battery should be plugged into the connector “ext Batt” on ZOK-Ex
electronics and placed between the battery terminals as shown below:

2. The ATEX Battery should then be fixed with the help of a pre-mounted
detachable cable tie. If the ZOK-Ex electronics is delivered together with the
ATEX Battery, then the ATEX Battery will be fixed and connected from the
factory but without battery connector ‘EX Bat’ connected.
Cable tie
How to tie:
1. The cable tie is provided with rings over its body and one end of the cable tie
has a ring eye. The open end of the cable tie is to be inserted in the bigger
ring eye and should be pulled till the battery is completely fixed.
