1. General features

1.5 Supply

• M7000CB and M7000CB/EVO have a double power supply circuit, that means that they

can operate with both AC and DC supply or with only one of the two indifferently

• In presence of both power supplies, the energy is taken from the AC source

2.1 Selection keys

• The front panel of the electronic control box has two LED displays showing the voltages

of the two power sources with their correspondent keys – (A) for Main line and (B) for

Secondary line – which allows to select the measurements.

• The following keys: SET (E) - AUT (F) - MAN (G) - RESET (H) allow to select the operating

mode, which is indicated by the corresponding LED.

• A mimic diagram is located at the center of the front panel; it shows the status of the

circuit breakers for load connection.

• Two keys – (C) and (D) – can open and close the circuit breakers (buttons are active only

after pressing the MAN key).

C D

2.2 Measurement selection

• When the key located under each display (A) and (B) is pressed several times, it will be

possible to view the various measurements of the line sequentially.

• Line-to-line voltages, line-to-neutral voltages (in case of single-phase lines) are available

for each line.

• The combinations of the red LEDs indicate which measurement is selected. The list of

measurements may change depending on whether the electronic control box is set up for

the three-phase, two-phase or single-phase control.

• After 1 minute without touching the key, the measurement returns to the default mea-

surement, which may be the ﬁrst voltage line-to-line or the ﬁrst voltage line-to-neutral,

depending on how the voltage control is set up.

• In case of alarms or messages, the display will be occupied by the alarm code.

By pressing the selection key, it is possible to temporarily hide the alarm and access the

measurements.

• The following table describes the meaning of the various LEDs.

Some of them are bicolor and have a different meaning according to the color.

• The four keys SET / AUT / MAN / RESET can be used to select the required operating

mode, which will be indicated when the corresponding red LED lights up.

• If the LED indicating the selected operating mode ﬂashes, it means that the device is

communicating through the serial interface and that it could execute remote commands,

including the mode change as well.

3.1 Reset mode (red RESET key LED)

• The electronic control box does not execute operations but it just displays the status of

the voltages and the circuit breakers.

• The opening and closing control outputs of the switches remain all open, hence allowing

for the manual control from the front side of the motor controls. If the emergency input

is activated, the unit will in any case order the opening of the switches.

• The generator control output will set up for switching off the group.

• The status alarms of the circuit breakers are disabled.

• When an alarm occurs, it must be reset by pressing the RESET key. If you are already in

this operating mode, press the RESET button again.

3.2 Manual mode (red MAN key LED)

• The manual mode allows the operator to electrically open/close the circuit breakers with

the special keys located at the front side of the device.

• In this mode, the voltages are constantly monitored but the device just displays their

status.

• When one of the control keys is pressed for at least 300ms, the electronic control box

changes the status of the circuit breakers from open to closed and vice-versa.

• If a command is given to close a circuit breaker while the other is already closed, the unit

will initially open the other circuit breaker, wait for the interlocking time and then it will

close the required circuit breaker.

• In manual mode, all the status alarms of the circuit breakers (disconnected and tripped)

are disabled. The anomalous condition is signaled on the LED but it will not be stored or

dealt with as an alarm.

• It is possible to manually control the startup and shutdown of the generator by holding

down the key (G) MAN for 5 consecutive seconds. As long as the manual mode is kept,

the status of the generator will remain the one required.

3.3 Automatic mode (red AUT key LED)

• In automatic mode, the device independently executes both opening and closing

operations of the circuit breakers as well as the startup and shutdown of the generator,

if any.

• When the main line (MAIN) goes beyond the limits, after the set delay times, the device

disconnects the load from the main line and connects it to the secondary line (SEC),

thus controlling both the startup of the generator, if any, and the changeover times

between the circuit breakers.

• When the main line falls within the limits, the device switches again the load on it and

determines the cooling cycle, if required, of the generator.

• The automatic cycles of operation vary according to the type of application (utility-to-

utility, utility-to-generator).

3. Operating mode

Electronic Control Box

3.5 On-load test mode

• By starting from the automatic mode and by pressing the (F) and (D) key simultaneously

for 5 consecutive seconds, it will be possible to carry out an operational test (on-load

test) which will totally simulate a lack of the power line voltage lasting one minute.

• Hence, the unit behaves exactly as if the line has fallen out of the limits, thereby

using all programmed times and parameters for the changeover so as to verify their

adequacy.

• The execution of the on-load test is determined by TES ﬂashing on the display.

• To end the execution of the test in advance, repeat the procedure with keys (F) and (D)

for 5 seconds or start the reset mode.

3.4 Off-load test mode

• By starting from the automatic mode and by pressing the (F) key for 5 seconds, it will be

possible to test the generator for 5 minutes.

• The generator is manually started in order to check its operation but since the electronic

control box is in automatic mode, the voltage controls will remain active.

• By doing so, it is possible to verify the correct operation of the generator, thus maintaining

the coverage of the load. Under normal conditions, the load remains connected to the

main line, hence the generator operates with no load (off-load).

• The execution of the off-load test is determined by TES written steadily on the display.

• To end the execution of the test in advance, press the (F) key again for 5 seconds or start

the reset mode.

4.1 Utility-to-generator Application

• In the Utility-to-generator application (U-G, default setup) the load is normally connected

to the main line. If there is an anomaly on the line or in case of a transfer signal set from

the outside, a start signal will be sent to the generator which supplies the secondary

line.

• When the voltage of the generator reaches the programmed limits, the electronic control

box will order the changeover on the secondary line.

• When the main line returns, the load is transferred again and the generator is kept in

operation with no load for a certain period of time so as to allow its cooling.

• The unit sends a start/stop command to the group through a relay output and can receive

digital signals from the group indicating its status through programmable inputs.

4.2 Utility-to-utility Application

• In the utility-to-utility application (U-U), the load is normally connected to the main line

and the changeover to the secondary line occurs if there is an anomaly on the main line

or in case there is a transfer signal set from the outside.

4. Applications

Please note: The execution of

this test involves transferring

the load, hence a power failure

during the changeover due to

the interlocking times.

• The circuit breakers control is carried out through two separate relays, one for closing

and one for opening.

• In reset mode, both control relays remain open, except for the emergency condition

where the opening can be controlled.

• In case of an anomaly on the switch, hence causing an alarm, the control outputs will

both be opened till the resetting of the alarm.

• There are two separate modes for controlling the circuit breakers. These can be selected

by using the parameter P1.03

5.1 With feedback (default setup)

• The status indicated by the two-color front LED is the one detected by the auxiliary

contacts.

• The timeout alarms are enabled. They are generated if the circuit breakers do not reach

the required position within a programmable time P1.04 or immediately if they change

position when no command has been sent.

• The control outputs are timed. When the circuit breaker has executed the required

operation, the output still remains energized for a certain period of time (+1 second

during closing and +15 seconds during opening, in order to allow the springs of the

motor operators to be completely charged) and then it is released.

• The normal status of the control outputs is open.

• The interlocking times start when the ﬁrst circuit breaker is actually opened, detected by

the input, and last for 0.5 steady seconds.

Example of a changeover with

feedback, assuming a utility-to-

utility commutation.

The feedback input status is

shown in blue.

The status of the control outputs

is shown in green.

The changeover time is shown

in yellow.

5.2 Without feedback

• The circuit breakers status LEDs remain off.

• The timeout alarms are disabled.

• The Opening/Closing control outputs remain constantly in the required position for the

circuit breaker.

• The changeover times between the opening of a switch and the closing of another start

during the commutation of the outputs and are steady at 6 sec.

Example of a changeover with

no feedback.

The actual status of the circuit

breakers is shown in blue.

The status of the control outputs

is shown in green.

The changeover time is shown

in yellow.

The auxiliary contacts of

the circuit breakers are

wired in their imputs.

With the feedback is

necessary to use for the

opening operation of

DPX 250-630-1600 the

shunth trip relay or the

undervoltage relay.

The auxiliary contacts

of the circuit breakers

are not wired in their

inputs, hence the

electronic control box

is not informed on their

actual state.

Electronic Control Box

• TAny condition required to determine whether a supply source is or is not suitable is

determined by the user through the P0 menu (system nominal data) and the P2 and P3

menus (voltage control, main line and secondary line, respectively).

• It is possible to set up the system nominal data, such as nominal voltage and frequency,

through the P0 menu, which will be used as a reference for setting up the percentage

thresholds of the following menus.

• It is possible to set up a TV transformation ratio in case a lower voltage, relative to the

actual voltage of the system, is applied to the voltage inputs of the unit. Here, again, the

display and the setup of the thresholds will be executed in actual sizes referred to the

system.

• The electronic control box can be programmed to perform voltage controls on three-

phase, two-phase or single-phase nets (via the P0.03 parameter).

The following describes the anomalies monitored by the voltage control.

Columns M7000CB and M7000CB/EVO point out the presence of the function within their

unit models.

Control M7000CB M7000CB/EVO Description

Minimum voltage • • One or more phases too low

Maximum voltage • One or more phases too high

Phase failure • •

Threshold under which the device can

operate faster compared to a normal

reduction

Asymmetry

(unbalance)

•

Phases included in the Maximum-Minimum

interval, yet too different between each other

Minimum frequency • Frequency too low

Maximum frequency • Frequency too high

Sequence of phases • Reverse rotation of phases

•

Each anomaly has an independent delay time. The anomaly must last consecutively longer

than the time speciﬁed for invalidating the voltage presence signal.

• All controls, except for the minimum voltage control, can be excluded separately by

setting the related parameter to OFF.

• The minimum and maximum voltage limits are speciﬁed by setting up two thresholds

each, one which determines the point beyond which the voltage is no longer considered

acceptable (e.g. P2.01) and the other, closer to the nominal voltage, which determines

the point in which it becomes compatible again (e.g. P2.02). The distance between

these two thresholds determines the hysteresis. For instance, it may be considered

that when the nominal value is below 80%, the voltage may no longer be useable and

that in order to be considered useful, it must rise over 85%, thereby determining a 5%

hysteresis.

The same concept applies to the maximum voltage.

• As for the frequency thresholds, there is a ﬁxed 1% hysteresis of the nominal frequency.

• The retrieval after a phase failure occurs when the voltage rises above the minimum

voltage retrieval threshold.

Example of variation of the main

line voltage within the mini-

mum and maximum thresholds

and relative hystereses, with

indication of the presence /

absence delay times. The ex-

ample considers the second-

ary line voltage absent with its

circuit breaker open, hence

the changeover times are not

shown. The INTERR. bar repre-

sents the required status of the

main line switch.

The following messages can be displayed, at different moments:

Code Description

- - -

(Dashes) - The interlocking time is in progress.

They are displayed from the side in which the load is being transferred

Sta

(Start) - Indicates that the Start Generator command has been sent

Coo

(Cooling) - Indicates that the generator is being left running for the cooling

Tes

(Test) - When steady, it indicates that an off-load test - namely a power unit test

with the voltage controls active - is currently in progress

Tes

(Test) - When ﬂashing, it indicates that an on-load test, namely an automatic net

failure simulation, is currently in progress

Loc

(Locked) - It indicates that the keyboard function one is trying to execute is

locked

8. Diagnostic

messages

• When the unit is running, it is possible to verify a number of abnormal situations which are

signaled in different ways.

• Some alarms (tripped, withdrawn) have a dedicated LED which begins to ﬂash when the

alarms go on.

• Other alarms are signaled through a code which consists of an A (alarm) and a number

indicating which alarm it is. This code will be ﬂashing on one of the displays. If the code

refers to the main line branch, the alarm will be displayed on the left. Conversely, if the

code refers to the secondary line branch or if it is a generic alarm (e.g. battery), it will be

displayed on the right.

• When an alarm goes on, the red LED “ALARM” ﬂashes in sync with the dedicated LED or

with the alarm code.

• The Global alarm relay output is de-energized during alarm conditions whereas it is

energized under normal conditions. If the unit does not operate due to a failure or power

supply problems, it will generate an alarm condition on its contact.

• Some alarms are automatically reset when the conditions generating them fail to work.

• Other alarms, described in the chart in the RIT column, are retentive, thus they are

stored.

• Once the alarm has been stored, the abnormal conditions must be eliminated in order to

be reset. Also, the operator must press the RESET key or send a special message via the

serial interface.

too low

This occurs if the P0.06 parameter is OFF and

if the battery voltage measured remains lower

than the threshold % set with P1.09 for the

time set with P1.11

YES YES YES YES

A02

Battery voltage

too high

This occurs if the P0.06 parameter is not OFF

and if the battery voltage measured remains

higher than the threshold % set with P1.10 for

the time set with P1.11

YES YES YES YES

A03

Main line

switch timeout

It is generated if the main line switch does not

move to the position controlled by the unit

within the time determined by P1.04 or if it

comes out of the required position on its own.

The alarm can be generated when closing and

when opening. If there is no power on both

lines, the alarm will not be generated

YES NO NO YES

A04

Secondary line

switch timeout

It is generated if the secondary line switch

does not move to the position controlled by

the unit within the time determined by P1.04

or if it comes out of the required position on

its own. The alarm can be generated when

closing and when opening. If there is no power

on both lines, the alarm will not be generated

YES NO NO YES

A05

Main line incorrect

phase sequence

If enabled by parameter P1.02, it is generated

when a phase sequence – different from what

has been speciﬁed in P1.02 – is detected,

after a delay of about 500 ms.

In order for the sequence to be detected, all

three phases must be > 50VAC

YES YES YES YES
