The Apex 100 Rack is a multi-functional, electronic, electricity energy meter used for grid metering. It provides
high accuracy in measuring electrical and also in measuring instantaneous quantities such as current, voltage,
power, frequency etc. The Apex 100 offers extensive configurable functional features together with the high
accuracy enable application areas more numerous than for traditional electricity meters. Besides having well
designed traditional features such as meter registers, data logging and tariff capability, there are also extensive
functions for bi-directional communication, monitoring alarm conditions, total harmonics distortion for current
and voltage. The Apex 100 is a 0.2 class CT-PT meter. It supports an open data exchange protocol (as per
ICS DLMS) for ease of reading and integration with other systems.
1. Self-powered
2. APS
The self powered variant meter is powered from its three-phase/three-wire or three-phase/four-wire feeder line.
The auxiliary powered meter takes its power from the auxiliary AC and DC power supply bank.
Figure 1: An Overview
The meter stores data in non-volatile memory. The data transfer possible options available in meter is through
hand held unit (Optical 1107 & USB type A ports) for local reading and GSM/ GPRS modem (RS232 & RS485
serial ports) for remote meter reading applications. Apex 100 is specially designed for supporting data transfer
on TCP/IP channel by supporting in-built Ethernet port in meter.
Meters
This user manual describes the Apex 100 rack meter‟s functions and provides the information needed to
configure and use the meter. It also explains the different variants and mounting arrangements.
Care must be exercised during the installation of the Apex 100 meter and associated equipment due to the
presence of mains voltages. Various points under the terminal cover and on the main printed circuit board
(PCB) under the main cover operate at hazardous voltages.
Danger of Electrocution
After installation access to the connectors and conductors must be prevented by fitting the covers supplied,
ensuring that they are secured in position with the screws provided and if appropriate sealed in accordance with
local practice.

4.7 Events
The Apex 100 has a number of defined events and alarms that are stored in the meter‟s event log when they
occur. The events are arranged into eight compartments with an overall maximum of 250 events. An event is
displayed with a description, a time stamp and an OBIS code.
Events are logged if the condition for the detection of an event persists for a specified duration, known as the
persistence time. Each event can have a different persistence time for occurrence and restoration. The default
persistence time is 2 minutes for an occurrence as well as for restoration. The persistence time and limit can be
configured in the field using the tariff tool. The persistence time can be selected between 1 to 60 min.
There is a delay between detection and restoration points to guard against erroneous or faulty detection.
The Apex 100 conforms to IEC 62053-23 for quadrants see Figure 30Figure 29.
The Energy Channel Registers with their availability are shown in the table below.
Availability for
Notes:
A maximum of 16 day types can be created; each individual day type can have a maximum of 16 time zones
and eight TOU registers.
5.3.2 Seasons
A maximum of 16 seasons can be created for a year. In each season, from Monday to Sunday different day
types can be assigned for rate and MD registers.
The tariff defines up to eight rate registers and 16 time zones. The energy types for which these registers are
defined are selectable through the tariff and can be changed at run time. At any time there is only one rate
register active. The switching time has a resolution of 5 minutes.
The tariff defines up to eight Maximum Demand registers. The energy types for which these registers are
defined are selectable through the tariff. The switching times are specified to a resolution of 15 minutes. Any
number of the defined registers may be active at a time. The meter allows fixed block /sliding window based
demand calculations. The demand integration period can be 15, 30 or 60 minutes. Slide window resolution is 5
minutes. Demand integration period is done in multiples of the window size (or Demand Sampling Period DSP).
This selection can be done in the tariff and can be changed at run time. All the unidirectional energy registers
with a maximum of 14 energies can be selected for the MD registers.
For DIP of 60 min, DSP can be 00, 05, 10, 15, or 30 min
The tariff supports maximum demand triggers, which can be any of the maximum demand register parameters.
The meter logs maximum demand of other parameters only when the trigger parameter reaches the maximum
value of demand. If no triggers are defined then it will act as a self-trigger where all the parameters will
independently log their maximum demand.
Apart from the above mentioned eight TOD MD register, a separate register is available to record the maximum
demand during the entire day (i.e. 00-24 hours). This is known as the universal demand register. It is not
configurable through tariff.
The meter maintains current TOD cumulative demand and UMD registers for all the energy types selected in the
tariff. Each time the maximum demand registers are reset, the cumulative register increases by the value of
their source register.
Apex 100 has two parallel and individually configurable loggers. The following description covers both loggers.
Load profiling of energy and instantaneous parameters can be selected through the configuration and can be
changed at run time by downloading a new configuration into the meter.
Survey integration period is configurable in tariff and can be set to 1, 5, 15, 30 or 60 minutes and will be the
same for all the selected survey parameters.
The sliding survey integration period and window size should be the same as the MD. The sliding survey can
only be selected through the tariff.
For SIP of 60 min, SSP can be 00, 05, 10, 15, or 30 min.
Please note that all previous load survey data will be lost when a new load survey configuration is loaded, so be
sure to read the data before commencing a new configuration.

Note 1: Maximum number of load survey days can be limited at factory end.
Note 2: Sliding Survey is not recommended if meter is used for ABT application.
The tariff supports maximum demand triggers, which can be any of the MD register parameters. The meter logs
maximum demand of other parameters only when the trigger parameter reaches the maximum value of
demand. If no triggers are defined then it will act as a self-trigger where all the parameters will independently
log their maximum demand.
Apart from the above mentioned eight TOD MD registers, a separate register is available to record the
maximum demand during the entire day (i.e. 00-24 hours) known as universal demand register. This is not
configurable through tariff.
Load profiling of energy and instantaneous parameters are fixed at factory end, and these can‟t be changed at
run time. Survey integration period is fixed in tariff as 15 minute and it will be same for all the selected survey
parameters.
The meter is BIS compliant and supports minimum 22 days load survey data.
The memory can store up to 150 days for 10 parameters @ 15 min SIP.
A snapshot of cumulative energies is logged at midnight (00:00:00 hrs). A roll over log for a minimum last 22
days is maintained for BIS compliance. The following 10 energies are available for daily energy snapshots.
These are fixed at the factory end and cannot be changed in the field.
The Apex 100 Scaling Tariff supports CT / PT ratio adjustment, transformer loss, CT-PT error compensation in
the field.
The Commissioning and Configuration (CC) Tool is used for preparing the scaling tariff. The existing meter
configuration must first be opened and read. The configuration can then be modified using the CC Tool. The
Apex 100 does not require to be switched off during the configuration mode and will only implement the new
configuration when all the blocks have been received and authenticated
1. Commissioning
2. Error Compensation
3. Transformer loss
In a single scaling tariff, commissioning change, error compensation, & transformer loss compensation is
treated & logged as three separate transactions.
It is also possible to download a scaling tariff in meter (locally/ remotely) using a suitable tool.
5.7.1 Transaction
Transactions are communications with the meter, which involve some sort of data change within the meter. A
transaction log of the last 100 events is stored in the meter

Note:
* In a single scaling tariff, commissioning change, error compensation, & transformer loss compensation will be
treated & logged as three separate transactions.
†
In a Category „B‟ meter these transactions will be accepted but not used; the meter will continue with the
default data.
The Apex 100 uses DLMS, the new global protocol, for meter reading. This is the only protocol supported by
the meter for meter reading. In DLMS protocol the BCS is considered the client and the meter is the server. On
request by the BCS, the meter will send all its supported OBIS codes and expected queries. All DLMS meters
will communicate data only after „getting associated‟ with the BCS client. Meter reading is divided in to following
sessions:Single parameter sessionsProfile sessions
A list of parameters and their OBIS code are shown below in the table.

5.9 Profiles
Meter data is divided into logical data sets and then mapped onto DLMS profiles. The following profiles are
defined and may be implemented as per requirement. To read the profiles, the BCS server needs to send two
queries; one to capture objects and the other for its data. The profiles are shown below.
Instantaneous parameters
Event data
Data can be selectively read from the meter. Starting with the latest entry, the number of previous entries can
be read. The table below shows the profile with their granularity.
Note – Load survey parameter wise selectivity is not possible due to storage of SIP wise data in line with BIS
DLMS standard.
5.9.2 Security
In DLMS mode – the client-server security is part of the DLMS „getting associated‟ process. Once the
association is made, data is exchanged freely as per the support provided and no further security mechanism
on data is applied.
Third party interface is provided through Modbus communication. It can be also used for online monitoring. The
RS-485 port details are shown in Table 7Table 4
5.9.4 TCP/IP
To be added
5.9.5 USB
The USB connector is provided in the Apex 100 for the collection of meter readings in a USB pen drive. Only a
predefined profile will be accepted. The USB port will only detect pen drives; no other hardware, such as mass
data storage cards, cameras or mobiles will be detected.
1. Select the USB option from the meter display menu using the keypad .
2. Plug in the USB Pen drive to USB connector or first plug in the USB Pen drive in USB connector and select
the USB option from display menu
3. A meter reading will now be completed and saved on the USB pen drive.
1. Plug the USB pen drive into the computer USB port.
2. From M-Cubed, use the upload option to upload the meter reading file.
Note- In case user wants to read meters which do not have its respective schedule file available in pen drive
(but have any other meter schedule file available in it) then target meter will send complete meter data in pen
drive. This will help in avoiding another visit of user for same meter reading after making the schedule file for
that specific meter.
