5235 Single Phase Credit Meter – User Manual & Technical Specification
Issue: 4 5
The inputs and outputs of the 5235
Single rate version -versions A & B
Single rate meters display the total kWh reading only. The display is
configurable to show either whole numbers, 1 or 2 decimal places. The
meter is also factory configurable to display either 5 or 6 digits with roll over
to zero at 99999 or 999999.
Two-rate meter (external time switch) - D version only
kWh are recorded at a particular rate and displayed using the rate
enunciators on the left hand side of the display. The rate registers are
displayed between 0 and a maximum of 2 decimal places unless configured
to 3 decimal places of testing purposes via the optical port.
The rate register range is 00000.00 – 99999.99 kWh unless factory
configured to six digits. The diagram shows a display sequence for a four-
rate meter and total register below. In the two rate variant the meter may be
configured to operate between 1 and 2 rates via the Optical port.

D
Rate 2 Display
The type B meter has an optically isolated, voltage free open collector
Pulse Output that is configurable to between 1 and 1000 pulses per kWh.
To maximise operation with external monitoring devises, the pulse width
can also be configured to between 20 and 260 mS in 20 mS steps.
Configuration is made through the IEC 1107 port.
The output meets IEC62053-31: 1998 Class B, Maximum voltage 15Vdc.
The configuration is factory set allowing the meter to operate as a single or
two rate meter. Rate switching is achieved by switching neutral or live to
the input terminal. See wiring diagram for the D model.
