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.
Scope of delivery:
The standard delivery includes:
Flow counter/- unit/-- in plastic- universal housing with wall or pipe mounting set
Model: ZOE-ZX with universal housing ‘K’
OR
Oval gear flow meter DON- with electronics option –ZE/ZB in compact version
Model: ZOE-ZX with universal housing ‘M’
Operating Manual
Battery 3.6 V Lithium size AA for battery mode
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.

7.3 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 type of battery is required as a replacement for the supplied battery:
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
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.

7.5 Control Input
There is one control input available for external controlling of instrument functions. The
activation of its function can be done through:
a.) an active control input or
b.) Carried out by a passive N/O contact.
In both cases, the function will be activated on switching from HIGH to LOW level
(falling edge).
When using an active control signal, the signal amplitude of the HIGH level must be
from 5 to 30Vdc. When using simple normally open contact, the input potential is
internally pulled of HIGH, if the contact is open. If the contact is closed, the input
potential is pulled to GND and the control function is activated.
Function of control input:

8.2 Measuring Mode
After applying the supply voltage, the electronics starts in measurement mode. In this
mode, the input signals are recorded continuously; current instantaneous flow and
volume counter readings are periodically calculated and displayed.
On LCD, in addition to main display, the status and configuration of the pulse output
and supply voltage are also displayed.
8.2.1 Display range of the Volume Counter
The number of digits that appear on the display for volume counter (partial and total
volume counter) is limited to maximum 8 digits. If 8-digit display range is exceeded,
the display will signal/represent it by displaying 8 hyphen signs (--------). In this case,
the counter cannot be read. The user has then the possibility of changing the Unit of
the volume counter in the Volume Menu so that the counter values can be brought
back again within the display range.

8.3 Menu Mode
8.3.1 General
In the menu, all device parameters can be set. The individual parameters are
organized into groups according to their function. While the menu mode is turned on,
the input signal detection and pulse output are still active in the background. After
leaving the menu mode, all display parameters are then updated again in
measurement mode.
Note: The menu mode is not exited automatically even after a certain time without key
operation. The menu mode remains active (in battery mode) until the user has once
pressed the button.
In battery mode, a long stay in menu mode shortens battery life.

Measuring mode Menu mode-Main group
3-5 seconds
Menu mode Parameter selection mode-Sub group
To activate the Menu mode, the button must be pressed for 3-5 sec. The
parameters are divided into main groups and subgroups. For selection of main groups,
and buttons are used. In the main menu, all menu groups can not be
displayed simultaneously on the screen so the list of menu items can then be scrolled
up or down. To choose the selected item, button should be pressed and the
device goes into relevant sub-menu i.e. into the parameter setting level. For selection
of predefined parameter values, and buttons are used. After changing
the value of the parameter, button should be pressed to save it and to return to
the previous menu level. The return to the main menu or exit to the menu mode takes
place by repeatedly pressing .
