LCD Display Modes
There are five types of LCD display modes: automatic scrolling display, push button display, keypad
display, power off display, and meter abnormal display.
z
Automatic scrolling display
Meter display mode is default as automatic scrolling display when power on. After meter
operates for a certain period, which is automatic scrolling display interval default as 3s,
Meter User Manual-HXE34-KP 11 / 30
LCD display will switch automatically to next page in sequential order circularly. Maximum
32 display pages can be configured, for details please refer to Annex A.
z
Push button display
Once press the button in the front, automatic scrolling display/power off display will switch
to push button display. LCD display switches to next page in sequential order circularly at
each button-push. When there is no button-push within 30s, push button display will switch
back to automatic scrolling display/power off display. Maximum 32 display pages can be
configured, for details please refer to Annex A.
z
Keypad display
When press the numbers in the keypad, the meter will enter keypad display mode and
display relevant numbers in LCD. If there is no keypad operation after 20s, the meter goes
back to automatic scrolling display mode(when there is power in the grid) or power-off
display mode(when there is no power in the grid). When pressing effective shortcut key or
TOKEN and press ENTER key, the meter will display relevant indicating message. After
10s it will go back to automatic scrolling display mode(when there is power in the grid) or
power-off display mode(when there is no power in the grid).
z
Power off display
Meter only displays credit of meter during power off.
z
Meter abnormal display
Once fault or damage of meter memory is detected, automatic scrolling display will stop and
LCD will be fixed to display abnormal code “Error”.

2.7 Low Credit Alarm
In order to remind the user to recharge in time and to avoid inconvenience of power disconnection,
meter provides the function of low credit alarm, including visual alarm and audible alarm.
Visual alarm:
z When there is enough remaining credit, LED is green.
z When remaining credit is less than low credit alarm level 1, LED is red.
z When remaining credit is less than low credit alarm level 2, LED is red and flashes.
Audible alarm:
When remaining credit is less than low credit alarm level 3, buzzer is on. Customer can turn off the
buzzer through manual token insertion. In consideration of not disturbing customer during rest time,
audible alarm turns off automatically during 20:00-08:00.
z Cancel audible alarm
z no need to cancel audible alarm now
Meter User Manual-HXE34-KP 19 / 30
2.8 Emergency Credit
Contactor disconnects automatically and there is no power supply when remaining credit reaches
zero. However, in case that customer needs power supply and cannot go to purchase power
immediately, meter provides the function of emergency credit. Customer can use short code 811 to
get emergency credit and restore the power.
Under the mode of emergency credit, meter calculates the remaining credit as a minus value. When
remaining credit plus emergency credit reaches zero, contactor disconnects again. Function of
emergency credit can only be used once before next recharge. The emergency credit will be deducted
automatically during next recharge.

2.9 Friendly Mode
Meter provides two modes of power interruption: normal power interruption and friendly mode.
Under the mode of normal power interruption, contactor disconnects when remaining credit reaches
zero. However, under friendly mode, in order to ensure consumer’s power consumption, contactor
doesn’t disconnect during certain periods, i.e. overnights, at weekends or holidays, even if remaining
credit reaches zero. Certain periods are configurable.

Load Control
z When active power is larger than threshold A and for a consecutive period which exceeds delay
time B, contactor disconnects.
z Then, after delay time C, contactor reconnects and meter starts over the process of overload
detection.
z If there are overload events for consecutive 5 times, times of overload events is reset to zero and
contactor reconnects after delay time D. Then, meter starts over the process of overload detection.
z If there is no overload event for consecutive time E, times of overload events is reset to zero.
NOTE: during the load control process, if there is any power on and power off event, setting of max.
power, or clearing events, the load control will go back to initial status and restart.

z10,000 operations under no-load conditions.
NOTE: In order to make sure reliable contactor operation and to avoid meter reset due to contactor
operation, it is only allowed to operate the contactor when the voltage of power grid is higher than
the threshold of contactor operation voltage(50%Un by default).
2.15.2 Control Logic
zPrepaid control at local;
zRemote contactor control;
zPriority: Remote>local. Once the meter receives remote command of disconnection, contactor must
disconnect, even though the meter still has credit; once the meter receives remote command of
connection, contactor must connect, even though the meter doesn’t have credit.

2.15.3 Reason of Operation
z 00: Normal status
z01: Credit reaches zero, emergency credit has not been used
z02: Credit reaches zero, emergency credit has been used
z03: Overload and contactor disconnect
z04: STS test disconnection
z05: Meter cover open and contactor disconnect
z06: Terminal cover open and contactor disconnect
z07: Remote disconnection of contactor
z09: Overvoltage and contactor disconnect
z0C: Under voltage and contactor disconnect
z 0D: reverse current and contactor disconnect
z 0E: neutral line missing and contactor disconnect
z10: STS test connection
z20: Remote connection of contactor
Note: If contactor disconnection is caused by meter cover open or terminal cover open, contactor
will remain disconnected, even if meter cover and terminal cover are closed. Under this circumstance,
the meter needs a TOKEN to clear the events to connect the contactor.

RTC
z Calendar, time and leap year switch available;
z MCU internal RTC module, with 32768Hz crystal as clock source;
z Frequency correction to 32768 required;
zAccuracy0.5 s/d under normal temperature.
2.17
Battery
z Lithium battery, the capacity is 1200 mAh.
zWhen power off, meter starts to use battery to maintain RTC, LCD display, button operation and
event recording.
zWhen low battery is detected, LCD displays
.
z Lifetime is from 3~5 years, if meter works only with battery constantly.
zBattery is replaceable. User can only replace battery when the power is off. If battery must be
Meter User Manual-HXE34-KP 25 / 30
replaced during power on, the user shall be extremely careful and not get shocked.
zIt is highly recommended to replace battery within 1 minute when power on or synchronize RTC
after battery replacement.

3.3 Installation Requirements
The prepaid keypad meter should be installed correctly as this could determine the meter
functionality and lifespan. Please follow the prescribed procedures carefully.
When selecting a suitable position for the meter, the following should be considered:
z Security (indoors or outdoors) against tampering.
z General safety consideration in case of possible electric shock, fire, etc.
z For safety consideration, and avoid damage to the meter, install the meter where is far away
from any water tap.
z Keep the energy meter away from a stove or heater, or any compliance which will produce
heating exceeds meter’s limited heat withstand.
z Keypad of the meter should be accessible by user.
z The meter should be installed in a dry ventilated place to ensure the installation and use of
meter is secure and reliable. At places that are dirty or might damage the meter, a protection
cabinet or box shall be used to protect the meter.
z The meter should be fixed in a firm, fire-resistant surface that do not shake easily.
NOTE Make sure to disconnect the power of the power network before installing the meter.
4. Storage and transportation
Meters should be stored under temperature -25℃~+60℃, the humidity is <85%. The meter should
not be crashed during transportation and storage.
