4. Installation and commissioning

The installation and commissioning should only be carried out by trained personnel. Check the following points before commissio-

ning:

- that the limits of the operating temperature are not exceeded: –10 … +55° C

- that the maximum values for all the connections are not exceeded, see „Technical data“ section,

- that the connection wires are not damaged, and that they are not live during wiring,

- the polarity of the DC supply is correct.

The instrument must be taken out of service if safe operation is no longer possible (e.g. visible damage). In this case, all the

connections must be switched o. The instrument must be returned to the factory or to an authorized service dealer.

It is forbidden to open the housing and to make modiﬁcations to the instrument. The instrument is not equipped with an integrated

circuit breaker. During installation check that a labeled switch is installed and that it can easily be reached by the operators.

Unauthorized repair or alteration of the unit invalidates the warranty.

The national provisions have to be observed in the installation and material selection of electric lines!

(PC).

Rt: Termination resistors: 120 Ω each for

long cables (> approx. 10 m)

Rs: Bus supply resistors,

390 Ω each

The signal wires (A, B) have to be twisted. GND (G) can be connected via a wire or via the cable screen. In disturbed environments shielded

cables must be used. Supply resistors (Rs) have to be present in bus master (PC) interface. Stubs should be avoided when connecting the

devices. A pure daisy chain network is ideal.

You may connect up to 32 Modbus devices to the bus. A proper operation requires that all devices connected to the bus have equal

communication settings (baud rate, transmission format) and unique Modbus addresses.

The bus system is operated half duplex and may be extended to a maximum length of 1200 m without repeater.

PM 1001812 000 00 Device handbook SIRAX BM1450 8/36

4.3 Commissioning

Before commissioning you have to check if the connection data of the device match the data of the plant.

If so, you can start to put the device into operation by switching on the power supply and the measurement inputs.

It is to be noted, that the data given on the type plate are respected!

4.3.1 Operating the device

The following values of the SIRAX BM1450 can be conﬁgured and

programmed on site: voltage input, current input, shunt setting range,

number of channels and demand integration time.

There are three buttons on the front panel that allow the user to navigate

through the available measured values (instantaneous values, energy,

and min./max.) and to conﬁgure the device.

Operation is performed by means of 3 keys:

•

3 keys “ UP”, “ DOWN” and "OK" for navigation and for the

selection of values.

4.3.2 LED indications

The LED indicators are used for various purposes. They change color according to their status.

When more than one from the above conditions are applicable, the LEDs will

follow "OR" logic for alarm condition and "AND" logic for healthy condition,

i.e. it will glow red when even one of the alarm conditions is true and it will

only glow green when all of the healthy conditions are true.

PM 1001812 000 00 Device handbook SIRAX BM1450 9/36

4.3.3 Measurement Reading Screens

In normal operation the user is presented with one of the measurement reading screens out of several screens. These screens may be scrolled

through one at a time in incremental order by pressing the “ UP” key and in decremental order by pressing “ DOWN” key.

Example of a current display with the following values:

Channel 1: 10 A

Channel 2: 20000 A (20 x 10

)

Channel 3: 300 A

Channel 4: Overload condition

For channels 1 and 2, the LEDs light up green, so these channels

are in the normal state (good condition).

For channel 3, the LED lights up red and a measured value is

displayed. This means that a limit relay is used on this channel

and an alarm state is present.

For channel 4, the LED lights up red and -OL- is displayed on the

display. This means that the measured value is above the nominal

value on this channel.

Example of a power display with the following values:

Channel 1: 10 W

Channel 2: 20000000 W (20 x 10

)

Channel 3: 300000 W (300 x 10

)

Channel 4: Overload condition

For channels 1 and 2, the LEDs light up green, so these chan-

nels are in the normal state (good condition).

For channel 3, the LED lights up red and a measured value is

displayed. This means that one of the following conditions exists:

1. On this channel there is a limit relay and the alarm state is

given

2. Voltage and current values are in overload condition

Power import indicator Display Overload condition Energy import

Shown above are the import energy screens. The display of the meter can only accommodate 8 digits. So to display more than 8 digit energy, an

overﬂow screen is added. When the energy reaches the energy digit reset count, it starts the count from 0 again. When this happens the corres-

ponding overﬂow is increased by 1. The maximum value of the overﬂow is 2000 for individual channels. Thus the highest energy that the meter

can show is 200099999999 Mwh. To obtain the value for current energy reading, the user need to multiply the overﬂow count by 10 raised to

energy digit reset count for the corresponding channel and add the result in displayed energy reading.

Channel 1: [(100 x 10

) + 5030] = 10000005030 Wh

Channel 2: [(28 x 10

) + 14800] = 280014800 Wh

Channel 3: [(8 x 10

) + 250000] = 8250000 kWh

Channel 4: [(24 x 10

) + 4300] = 2400004300 MWh

PM 1001812 000 00 Device handbook SIRAX BM1450 10/36

4.3.4 Timer screen

As shown in the picture above, there are upto four timer screens

present in measurement screens. They show values of number of

cycles, on delay and o delay for corresponding timer. When timer

is running, these values are shown in countdown mode.

are shown in countdown mode.

If number of cycles is set as 0, then on this screen number of cycles

will always increment from 0 up to 9999.

Note: 1. Press UP key to start the timer

2. Press down key to stop the timer

Timer unused: Timer is not selected as a relay output

4.3.5 Number of Interruptions

This screen shows the number of power supply interruptions that

the meter has encountered. After 9999 this value will start it's

count from 0. User can reset this count in the reset menu.

4.3.6 On hour

This screen shows the total number of hours the auxiliary supply

has stayed on. Even if the Auxiliary supply is interrupted count of

on hour will be maintained in internal memory & displayed in the

“hhhhhh.mm” format. For example if displayed count is 105000.10

it indicates 105000 hours and 10 minutes. After 999999.59 On

hours display will restart from zero. The user can reset this value in

reset parameters menu.

4.3.7 Run hour

This Screen shows the total no. of hours each of the load has been

connected. Even if the Auxiliary supply is interrupted, count of

Run hour will be maintained in internal memory & displayed in the

format “hhhhhh.mm”.

For example if Displayed count is 105000.10 it indicates 105000

hours & 10 minutes. After 999999.59 run hours display will restart

from zero. The user can reset these values in reset parameters

menu.

Alarm high:

If the option High alarm activated or Alarm high deactivated is selec-

ted, the relay will go into alarm condition if the measured parameter

is greater than the set limit.

Alarm low:

If the Low alarm or Low alarm option is selected, the relay will go into

alarm when the measured parameter is less than the set limit.

Relay activated / relay deactivated:

Relay activated means that the relay switch is closed in the alarm

state. Relay deactivated means that the relay switch is opened in the

alarm state.

Trip Point

This parameter decides the limit for a particular measurement para-

meter, crossing which the relay goes into alarm mode. These values

are deﬁned in percentage of nominal value(except for energy and

ampere hour parameters).

For high alarm conﬁguration, the ranges are 10-120%.

For low alarm, conﬁguration, the ranges are 10-100%.

For energy and ampere hour parameters the ranges are 10-9999999.

Example: If nominal voltage value is 48V and trip point is 60%, the

absolute value of trip point will be 28.8V(60% of 48).

Hysteresis

Hyteresis is the oset value below high alarm trip point or above low

alarm trip point, which when crossed by the measured parameter,

resets the relay to its position before tripping i.e. normal condition.

The value of hysteresis can range from 0.5 to 50% and it gets calcu-

lated on trip point value.

Example: If trip point is 60% and hysteresis is 25%, then hysteresis

value will be equal to 15%(25% of 60). To get absolute value of

hysteresis subtract this much part of nominal value from the trip point

in case of high alarm or add this to the trip point value in case of low

alarm.

Example:

Nominal value= 48 V Trip point = 60%

Hysteresis = 25% Trip value = 60% of 48 V = 28.8 V

High alarm Hysteresis value = 25% of 28.8 V = 7.2 V

Relay will trip above 28.8 V & it will reset below 21.6 V (28.8 V - 7.2 V)

For negative values of trip point, calculations will be the same as

positive trip point. Only a negative sign is applied to calculated

hysteresis value.

Example: for dierent conﬁgurations

Parameter N0: 4 (current 1)

Trip point = 50% Hysteresis = 50%

Absolute hyteresis value = 50% - (50% of 50%)

= 25%
