WSZ14DRS-32A Single Phase Energy Meter
28 032 715 – 1
Single-phase energy meter WSZ14DRS-32A with display, with MID approval
Only skilled electricians may install this electrical equipment otherwise
there is the risk of fire or electric shock!
Temperature at mounting location: -25°C up to +70°C.
Storage temperature: -25°C up to +70°C.
Relative humidity: annual average value <75%.
RS485 bus single phase energy meter WSZ14DRS-32A with display, with MID.
Maximum current 32 A. Standby loss 0.4 watt only.
Modular device for DIN-EN 60715 TH35 rail mounting.
1 module = 18 mm wide and 58 mm deep.
Connection to the Eltako RS485 bus. Bus wiring and power supply with jumpers.
The meter reading, the instantaneous power and the serial number are
transferred to the bus – e.g. B. for transfer to an external computer, to a
controller – and also sent to the radio network via the FAM14. For this it is
necessary that a device address is assigned by the radio antenna module FAM14.
This single-phase energy meter measures active energy by means of the current
between input and output. The internal power consumption of 0.4 watt active
power is neither metered nor indicated.
1 phase conductor with a max. current up to 32 A can be connected.
The start current is 2O mA. Accuracy class B (1%).
If the anticipated load exceeds 50%, maintain an air gap of ½ pitch unit to
the devices mounted adjacently. If necessary, use spacer DS12.
Two N terminals for secure cross wiring of several counters.
The consumption value is stored in non-volatile memory and is displayed again
immediately after a power failure.
The 7 segment LC display is also legible twice within a period of 2 weeks
without power supply. Press the button.
Power consumption is shown by a bar flashing at a rate of 1000 times per kWh.
The meter terminals must be protected against tampering by installation in a
sealable distributioncabinet.
Error message
In case of a connection error, the background lighting of the display flashes.
When the display is running, it shows the total active energy and the display
bars are in the kWh position.
Press the button under the display to switch on the background lighting. Then
you can browse through the menu. The bar moves to the current display: the
cumulative power of the resettable memory RS (kWh), the current power P (kW),
the current voltage U (V) and the present current I (A) will be displayed
successively. In the end it will be browsed to the activeenergy display (kWh).
The program automatically returns back to normal display (kWh) 20 seconds
after pressing the button and the background lighting will be swiched off.
The memory RS is reset by pressing the button for longer than 3 seconds while
the memoryis displayed. Then confirm the message ‘reset’ by pressing the
button again for 3 seconds.
Assign device address for the WSZ14:
Normal display: Short press the button, the backlight will turn on. If the
button is pressed for more than 3 seconds, the device address Adr appears on
the display. Now turn the rotary switch on the FAM14 to position 1 within 60
seconds; its lower LED lights up red. After the address has been assigned by
the FAM14, its lower LED lights up green for 5 seconds and the normal display
appears again on the WSZ14.
Delete device address of the WSZ14:
Normal display: Short press the button, the backlight will turn on. If the
button is pressed for more than 3 seconds, the device address Adr appears on
the display. Now hold the button down again for 3 seconds, LEArn appears in
the display. Then press the button briefly, rESEt.A appears in the display.
Now keep the button pressed for 3 seconds, the device addressis set to zero
and the normal display appears.
Send learning telegram:
Normal display: Short press the button, the backlight will turn on. If the
button is pressed for more than 3 seconds, the device address Adr appears on
the display. Keep the button pressed for 3 seconds again, LEArn appears in the
display. Now press the button again for 3 seconds, a teach-in telegram and a
data telegram are sent. The FAM14 must be operated in position 2 or position 5
so that the telegrams of the WSZ14 can be sent to the Eltako wireless network.
A data telegram with meter reading, power and serial number is sent
automatically after switching on the supply voltage and cyclically every 10
minutes. If the meter reading changes by 0.1 kWh, the meter reading telegram
is sent.
PcH is the value (delivery condition 200 watts) of the necessary power change
so that a power telegram is sent immediately.
Change PcH value:
Short press the button, the backlight will turn on. Then press the button
repeatedly until PcH appears in the display. Now press and hold the button for
at least 3 seconds until the first digit of the number flashes. The number
then ncreases with each press of the button.
Between 10 to 100 in increments of 10 and from 100 to 1000 in increments of
100. If the selected value is to be saved, press and hold the button again for
3 seconds. SEt appears in the display.
Now you can switch between SEt and ESc with a short button press. By pressing
the button for at least 3 seconds, the value is saved with SEt, with ESc the
value is discarded. After briefly pressing the button, the normal display
appears.
Meter special operating modes:
In the meter operating modes of the FAM14, the focus is on the adjustable
transmission speed of electricity meter data for external building energy
managers.
Data can be accessed and forwarded via gateways connected to the FAM14 (FGW14,
FGW14USB, FGW14W(L)-IP).
Additional setting options are available on the FAM14 for meters from
production week 33/23.
