Operating instructions, data sheet, approvals and further information via the QR code
on the device or via www.kobold.com
The devices are only to be used, maintained and serviced by persons familiar with these
operating instructions and in accordance with local regulations applying to Health &
Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the machines
fulfil the EC-machine guidelines.
3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of the
delivery packaging. In case of damage, please inform your parcel service / delivery
agent immediately, since they are responsible for damages during transit.

4. Regulation Use
The electronic units ZOE-ZX are specifically designed for the calculation, display and
transfer of calculations and flow rates of flow meters with pulse or frequency outputs.
The instruments display flow rate, day counter (resettable) and total counter in the
operator-selected units. A menu guides you through the programming of the device that
largely eliminates the requirement of constant usage of operating manual. All user-
specific program settings are retained even when changing the battery.
A trouble-free operation of the device is only guaranteed if all instructions in this manual
are complied. We do not accept any liability for damage caused by failure to follow these
instructions.
5. Environment
The electronic options ZOE-ZX are weather resistant and adequately reflect IP66/67
(NEMA 4X). The electronics are housed in a UV-resistant, glass-filled nylon housing
with stainless steel screws and FPM seals.
The instruments are suitable for harsh indoor or outdoor environments and comply with
EU Directive 2014/30/EU (Electromagnetic Compatibility).

7. Electrical connections
7.1 Cable entry for housing option -K
Up to 3 cable entries (M20x1.5 or ½ "NPT) are available for electric connection in case
of electronics with plastic housing. To use these cable inlets, the existing factory
protection caps must be broken with a tool (e.g. screwdriver) and a suitable cable gland
should be screwed in. The cable glands are not included in the delivery.

7.2 Overview of Terminals ZOE-ZX with Supply option B and 3
Supply option B
(Battery supply - either 1 x 3.6 V or 2 x 1.5 V)
Supply option 3
(external DC supply or depending on the used sensor with battery)

7.3 Power Supply
Depending on functionality and features, the electronics offer different possibilities for
power supply:
Options ZOE-ZExxx3xx: Battery and ext. DC-Supply
Options ZOE-ZBxxxBxx Battery operation
7.3.1 Storing the counter readings
The storage of meter readings is carried out after each measurement cycle in the internal
FRAM. If the power is interrupted and re-applied, than the meter reading revert to the
last saved values.
7.3.2 External DC-Supply
When electronic units are supplied with external DC voltage, all functions are available
i.e. Pulse output, display backlight and sensor supply can be used as needed.
If the device is taken out of operation and not used for longer periods,
the battery must be removed. Otherwise, the device is always supplied
by the battery and remains active. As a result, the battery can get
discharged.
7.3.3 Battery operation (ZOE-ZB with supply option B)
The option ZOE-ZX can also be powered by a battery. In battery mode, the device
function scope is relatively limited:
Pulse output is not available.
The backlight of the display is switched off and cannot be turned on.
Only passive sensors may be used like reed switches, as they require no
additional power supply. Usage of induction coils reduces the battery life. Other
sensors, which require a sensor power for operation, are also not suitable for
battery operation.
The supplied battery type 3.6 V AA Lithium (2200 mAh) should be inserted in the battery
holder on the back side of the electronic (correct polarity is important!).
The following battery type is recommended as a replacement for the supplied battery:
a) 3.6 V lithium, size AA, capacity at least 2200 mAh, IEC type CR14505
For example: EVE type ER14505M, SAFT LS14500, Emmerich ER 14505, VARTA
CR 14505
b) 2 x alkali, size AA, IEC type LR6
Battery life duration: The achievable battery life is dependent on various factors:
On the total number of detected input pulses and the input frequency(higher
frequencies reduce the battery life)
On the environmental conditions - low temperatures reduce the usable battery
capacity.
