THOROUGHLY!

5. INSTALLATION

Degree of protection and conditions of service: those stipulated in the technical specifications of the equipment must meet the requirements of the type of installation.

Fastening the casing: this must be implemented through the special holes (already present or drilled) at the bottom or with the fastening brack-ets, if supplied.

Passing the connection cables: this is imple-mented by means of cable glands that must be installed on the lower part of the casing, after having drilled appropriate holes. The hole must have an adequate diameter for the cable gland to pass and must not have any burrs, so as to further guarantee the required degree of protection once the assembly process is complet-ed.

Connecting the cables in the terminal block: this must be implemented with the use of a tool of the right size, so as to avoid damaging the ter-minal itself.

Cleaning the casing: this must be implemented once installation is completed. This consists of the removal of all kinds of metal and/or plastic impu-rities that may have fallen inside the casing (for example, screws, washers, lengths of wire, sheath, drilling chips, dust, etc.).

Take great care when drilling and fas-tening so as to avoid touching or dam-aging the components and any control boards inside the equipment.

FASTENING THE EQUIPMENT

5.1 PRELIMINARY OPERATIONS

5.2 CONNECTION

6.2 OPERATION MODES

Each motor set to work in this function mode is con-trolled by the status of the sensors: SL/SP 1, SL/SP 2, connected respectively to

the following inputs “S1”, “S2”, start up and shut down the motors (the inputs depend on the mod-el of equipment).

SL/SP STOP connected to the "S0" input stops the motors or enables the motors to run.

SL/SP MAX connected to the "W" input emits an alarm signal.

The “Dry Running” protection stops the motor stops the motor that detected it, if enabled and triggered.

ALTERNATE START-UP This function is only available if both motors are enabled for AUTOMATIC operation. The closing of control inputs "S1", "S2" triggers the start-up of the respective motor which, in accordance with the setting of the micro switch, can be: J1-4 (=OFF) non-alternating; rather, each in-

put controls its motor (e.g.: "S1" controls motor 1, "S2" controls motor 2). (=ON) alternating at each command from the first input that closes; rather, with the motors stopped, the closing of the first input starts up the other motor, if available. (e.g. "S1" controls one of the two motors and then "S2" controls the other motor). The first motor that starts is the last to stop. A motor that runs continuously for 12 hours is shut down to start up the other motor if it is stopped, in AUTOMATIC mode, without active alarms.

AUTOMATICO

REPLACING THE MOTOR IN PROTECTION MODE When the “Alternating start-up” function is enabled, the intervention of any of the motor’s protective devices, with the exception of the “dry running” device, starts up the other motor if it is stopped, in AUTOMATIC mode, without active alarms.

DELAYED START-UP From the closure of control inputs "S1", "S2" ... the first motor to start is started up immedi-

ately without delays; the second motor to start is started up with a

delay M2 START DLY (0—30s) set on the po-tentiometer. The motors are never started up at the same time. The events are at least 2 seconds apart, even if the delay is set to 0s.

DELAYED SHUTDOWN From the opening of control inputs "S1", "S2" ... the second motor to start is stopped immedi-

ately without delays; the second motor to start is stopped with a

delay M1 STOP DLY (0—180s) set on the po-tentiometer.

The motors are never stopped at the same time. The events are at least 2 seconds apart, even if the delay is set to 0s.

SELF HOLD Enabled via micro switch setting: J1-3 (=OFF) not enabled; rather, each "S1",

"S2" control input starts up and stops its relative motor. (=ON) enabled; rather, each "S1", "S2" control input only starts up its relative mo-tor, while shutdown is carried out only via intervention of "SO" input.

PERIODIC RELEASE OF THE IMPELLER This protects the electric pumps from a long peri-od of idleness by starting up and running the pumps for 2 seconds periodically every 48 hours. The time elapsed since the last start-up is stored internally, even in the event of a power failure, and when it returns, the count resumes as nor-mal. The function is only active in AUTOMATIC mode, therefore: A motor at a standstill when OFF is selected

on the button is excluded from the control and does not trigger release start-up.

a motor started up in MANUAL mode is not considered as a release event.

The operation modes are individual for each motor. The mode is selected via the buttons of each motor and is reflected by the light signals between the but-tons as described in the CONTROL BUTTONS and MOTOR LIGHTS paragraphs in the CONTROL PANEL chapter of this OPERATION AND USE section. The function modes are described in the following paragraphs:

AUTOMATIC PERMANENT HAND TEMPORARY HAND OFF

DESCRIPTION

19

Each motor set to work in this function mode is con-trolled by the control button and status of some sen-sors: SL/SP STOP connected to the "S0" input stops

the motors or enables the motors to run. SL/SP MAX connected to "W" input, emits an

alarm signal and cannot modify motor status. The intervention of the "dry running" protection de-vice, if enabled, stops the motor that detected it. Note: 1) the PERMANENT HAND mode is the same as the

AUTOMATIC with SL/SP 1, SL/SP 2 (inputs “S1”, S2”), always closed .

2) the shutdown and restart of the motors caused by the SL/SP STOP (input “S0” is immediate for all motors (not sequential).

PERMANENT HAND 6.3 COMMON FUNCTIONS

The system controls the smooth operation and when the electric pump no longer suctions water, in accordance with the setting of the micro switch, this causes: J1-8 (=OFF) protection disabled: no action on

the motor; (=ON) protection enabled: motor stops after about 10s at start-up or after 3s dur-ing normal running. An attempt to restore a motor stopped due to protection device intervention is carried out automatically after 10 minutes. The waiting time while attempting to re-store can also be cancelled by pressing the RESET button for the relative motor. The stopping of one motor does not cause start-up of the other motor, even if availa-ble.

DRY RUNNING PROTECTION

It is possible to select the input status for which running consent of motors is given via micro switch setting: J1-1 (=OFF) input closed.

(=ON) input open.

“SO" STOP INPUT

Via micro switch J1-6 setting, the following can be signalled as an alarm: stop condition via "SO" input provided that

the "Self hold" function is excluded (J1-3=OFF).

intervention of the “Dry Running” protection. J1-6 (=OFF) no alarm signal.

(=ON) active alarm signal.

ALARM FOR STOP VIA "SO" OR VIA "DRY RUNNING" PROTECTION

It is possible to select the input status for regular operation, meaning the absence of an alarm, via micro switch setting: J1-2 (=OFF) input closed, no alarm.

(=ON) input open, no alarm. Alarm reset is performed as soon as the input is set to normal status, according to the setting described above.

"W" ALARM INPUT Each motor set to work in this function mode is stopped and cannot be started regardless of the sta-tus of the sensors.

OFF

Each motor set to work in this function mode is only controlled by the control button, whereas all the sensors connected to the inputs do not intervene on operation. The DRY RUNNING protection does not intervene and does not stop the motors even if enabled. This is useful when maintenance must be imple-mented on the system. Note: The TEMPORARY HAND mode forces the

operator to be constantly present because s/he makes the motor run regardless of the status of the sensors.

It is recommended to use the "TEMPORARY HAND" mode only if nec-essary and always when managed di-rectly by the operator.

KEY To allow for some system tuning operations, it is possible to temporarily disable motor protections such as "overload, minimum load, dry running" via micro switch setting:

J1-7 (=OFF) protections disabled: protections do not intervene for a brief amount of time (10s) from when the motor is started. Running is permitted even if nominal cur-rent registration has not been performed (see chapter COMMISSIONING, section INSTALLATION). () The OFF status of the selector is sig-

nalled by means of a single Beep. (=ON) protections enabled: protections intervene according to their set modes.

MOTOR PROTECTION ENABLING

We do not recommend excluding pro-tections. Their exclusion should last no longer than necessary for tuning and then must immediately be re-enabled. This remains the responsibility of the operator.

Each potentiometer is independent and acts only on its own engine. REC: select the mode (alternative to buttons) for

recording the motor current. TEST: select the mode for comparing the detected

motor current with the one recorded. 90—130%: in normal mode, select the intervention

threshold of motor overload protection with respect to the recorded current. We recommend setting a value not less than 110%. Lower protection is achieved by setting a value between 110% and 130%. The 90% value is used only in the case of monitoring and tuning the system.

For further information, see this section in the CUR-RENT PROTECTIONS chapter.

While the recording mode is active, the motor must be started up in PERMANENT HAND mode by press-ing the HAND-OFF button of the motor in question once, briefly.

The recording process is completed in about 20 se-conds. The motor shuts down automatically. If necessary, it is possible to halt motor running be-fore the time expires, again by pressing the HAND-OFF button once, briefly. If the process has been successful, the motor indi-cator lights go off and no signal is given.

It is essential to record motor data for electrical panel operation. It is independent for each motor and consists of self learning the current and cosφ of the motor at speed and during regular operation with the electrical pan-el in “REC” recording mode. The “REC” recording stage can be activated in two ways: 1. By push buttons: When the panel is on, press

and hold both the HAND—OFF and AUTO—RESET buttons on each motor for more than 5 seconds. A double flash of the OPERATION indicator light (control panel) indicates that recording is active.

By potentiometer: When the panel is off, using the internal “OVERLOAD” potentiometer for each motor positioned in “REC” mode. Close and switch on the equipment. A double flash o f t h e “ O V E R L O A D ” indicator light indicates that recording is ac-tive (NB: the indicator light is not visible with the equipment closed). .

ATTENTION If “REC” mode has been activated using the keys, after successful recording the system exits that mode and is ready for normal operation. The OPERATION indi-cator light also goes off and no longer emits a double flash. If the “REC” function has been activated by the potentiometer, it is necessary to return it to normal operation (“100-130%”) within 90 seconds. Otherwise, the TRIP indicator light will flash 4 times …………… To exit “REC” mode, push the buttons or switch off the device or position the potentiometer correctly.

If recording has found any invalid conditions, the data in the memory will be cleared and this will be shown on the “TRIP” and/or “RUN” indicators lights for the motor in question:

Recording must therefore be repeated once the fault has been resolved. To exit “REC” mode, press the HAND-OFF and AUTO-RESET buttons again or position the potentiometer correctly.

CHECKING MOTOR DATA “TEST”

It is not normally necessary to check motor data, but this may be useful in particular cases when checking and commissioning the electrical panel. It is independent for each motor and consists of comparing the current and cosφ recorded previously with those of the motor at speed and during regular operation with the electrical panel in “TEST” mode . The “TEST” stage can only be activated:

When the panel is off, using the internal “OVERLOAD” potentiometer for each motor positioned in “TEST” mode.

Active verification is signalled by a single flash of the internal “OVERLOAD” light for the motor in question. Motor data verification is started up in the same way as recording mode, i.e.:

Starting up the motor in “PERMANENT MANU-AL” mode.

Waiting for automatic completion. Checking the absence of signals on the “TRIP”

indicator lights. Moving the potentiometer back to the normal

operation positions (“100—130%”) within 90 seconds, otherwise, the TRIP indicator light will flash 4 times ……………………………

Verification or recording must therefore be repeated once the fault has been resolved.

OVERLOAD PROTECTION TRIGGER THRESHOLD

Normal electrical panel operation requires the “OVERLOAD” potentiometer to be positioned at a value between 100 and 130%.

We recommend setting a value not less than 110%.

Lower protection is achieved by setting a val-ue between 110% and 130%.

The 90% value is used only in the case of monitoring and tuning the system.

When the current measured exceeds the current recorded by the set % value, the “OVERLOAD” indi-cator light flashes and when the accumulation of energy [I2t] exceeds the limit value, the overload protection device is triggered and stops the motor. The internal “OVERLOAD” and the external “TRIP” indicator lights come on.
