r The EPC-41 control unit controls the separation process. It can be programmed for diffeent separation systems and different condi-tions within the system, by setting parameterThe process parameters can be easily adjusas often as required, to meet changes in theoperating conditions, e.g. oil temperature, alarm points, time between sludge discharge

Each separator has its own EPC-41 control unit. Up to three separation systems can beinterconnected via cables between their control units. The separators can work in paralleor series operation. Only two separators canwork in series; the third must work in paralleor act as a stand-by. The first separator in series should always be defined as a purifieand the second as a clarifier.

NOTE

P2 is factory set to P (purifier). If you change it to C (clarifier) you get all the factory settings for a clarifier, which is shown in column Factory set value, Clarifier in the tables.

5.2 Alarm Log

By setting P90 to 50, the mode selector in position L and then by pushing the alarm resbutton, the 32 latest alarms can be displayed, including self resetting alarms.

Each logged alarm consists of three consecutive groups of information:

1. The accumulated alarm log time, which shows how long the EPC has been in operation since an alarm.

If the interval between two alarms is greater than 999.5 hours ( 41 days) the whole alarm log will be reset to 0.

2. The alarm is indicated in the same way awhen it occurred, except for the alarms starting with an E:

alarm code starting with an A.

LED and an alarm code, for instance High or low oil temperature.

LED indications only.

alarm code starting with an E (eventswith no alarm released)

There is only one event for EPC-41, which is a self resetting function; E2 = low pressure

t s

6.1 Process ParametersP1 Max time between sludge discharge

Long intervals between sludge discharges can cause the sludge to accumulate and solidify. The sludge may then break up at sludge discharge and create imbalance in the bowl.

As many factors influence the sludge discharge interval, the choice of interval must be based on experience.When the bowl is opened for routine cleaning, the sludge space should be inspected and, if necessary, the interval between discharges changed accordingly.

Clean sludge space: the interval may be prolonged. Clean sludge space means that no noticeable amount of solidified sludge remains in the sludge space.Dirty sludge space: the interval must be shortened. Dirty sludge space means that some solidified sludge has accumulated in the sludge space.

The only way to get a clean sludge space is to make appropriate adjustment of the interval based on regular inspection.

N.B. Alfa Laval assumes no responsibility for the actual choice of discharge interval times, as these depend entireon local feed characteristics.

Fuel oil cleaningConditions may change completely when bunkers are changed. Thereforegreat care must be given to the discharge interval setting for each newbunker. In case the current discharge interval exceeds the recommended initial value, the interval setting has tobe reduced according to table on nexpage, when a new, unknown bunker ito be separated.

Use of unstable fuel or mixing of incompatible fuel oils may cause precipitation of sludge and overloadingof the separator.

WARNING


If the interval between sludge discharges is too long, there is risk of heavy side breakdown.

WARNING


Each new bunker requires review of the discharge time setting.1810108-02 V1 13

P4 Sludge discharge signals from purifier to clarifierThe number of sludge discharges initiated by the first separator (purifier) before a discharge signal is sent to the second separator to start its sludge discharge sequence. P4 should be set in the purifier controller.

P5 High temperature alarmP5 should be set sufficiently above the temperature set point P7. 5 10 C (10 20 F) higher than P7 is recommended.If P5 = 0 (monitoring temperature sensor (Pt 100) not connected)then P6 = P7 = - - -.

P5, P6 and P7 can be set both for heavy fuel oil (HFO) and for diesel oil (DO), see P15. If both oils are to be used, the following must be done:

1. Set P5, P6 and P7 for HFO (P15 is factory set to HFO).

2. Change P15 to do.

3. Go back to P5 and set P5, P6 and P7 for DO.

If only diesel oil is to be used for the installation, the following must be done:

1. Set P5 greater than 0.

2. Change P15 to do.

3. Go back to P5 and set P5, P6 and P7 for DO.

How to set P8 and P9:If the temperature varies with regularlyrepeated oscillation, setting of the proportional band and integral time isnecessary.

Increasing the value of parameterP8 (proportional band width) will result in a slower and more stablecontrol action.

Increasing the value of parameterP9 (integral time) also results in slower response from the EPC-41

We recommend that you follow these guidelines:

1. Set P9 = 10 minutes.

2. Decrease P-band (P8) band in steuntil the process reaches the poinwhere it starts to oscillate with a constant amplitude. Test the stability after each step by introducing a step-change of load or set point.

3. When you have discovered the point where the process oscillateswith a constant amplitude note thefollowing figures:

4. Calculation of optimal parameter settings.

The settings above give a rather goodresult but may be adjusted accordingto individual characteristics in differentloops.

t.d P15 HFO / DO selection of oil typeTo prevent false alarm (A7-10) when cleaning diesel oil the type of oil must be specified.Once P5, P6 and P7 are set for HFO or DO they automatically follow the selection of P15.If P15 = HFO and P5 is set > 0 then P5 for DO is automatically reset to 50 C (120 F).If P15 = do then P53 =P70 = 0.See P5 for the relationship between P5, P6, P7 and P15.

6.2 Installation ParametersP23 EPC-41 address

If the separator works as single unit the EPC-41 address shall always be 1. When using more than one separator in the same system (parallel or series) each interconnected EPC-41 control unit must be identified. The EPC-41 address shows in which order the control units are linked.See also P3 for the relationship between the parameters.

P34 Alarm delay timeActivation of most alarm functions can be delayed up to 30 seconds, except for

emergency / vibration alarm

high temperature alarm,which have a fixed delay time of 2 seconds.

If operating two separators in series, P34 for the clarifier separator must be 3 seconds longer.

P35 Low temperature alarm delay after MV1 change overWhen the oil feed change over valve changes position the flow rate and thuthe oil temperature may be influencedBy delaying the temperature alarm, a false alarm is avoided as the oil temperature has time to stabilize.P35 should be set according to plant application. If a delay time above 120seconds is necessary, check the heatisystem and the installation layout.

P36 Remote controlRemote control can be applied in formof:

external switches

P37 Heater typeThe EPC-41 control unit is designed for control of:

Heatpac EHS-62 (P37 =1)

Heater with heating media controlvalve (P37=2)

N.B. If a different type of heater is installed(P37 = 0), only a start/stop signal is available from the EPC-41 control uniIf a steam heating system is connecteto the EPC-41 and if the system is equipped with an optional shut-off valve, and provided P37= 0 or 2, the valve is opened when the heater is started.

6.3 Timer Sequence Parameters

6.3.1 Starting Sequence

P50 Bowl closing waterFor proper closing of the separator bowl during start-up sequence. If more than 60 seconds is required, it may indicate a malfunction.

P51 Sealing waterSealing water is used in the bowl to prevent oil from discharging through the water outlet in a purifier. The amount of sealing water in the bowl is balanced by the gravity disc. During the starting sequence, sufficient water must be admitted to the empty bowl to establish an adequate water seal.Insufficient water will lead to a broken water seal. If a broken water seal occurs during the starting sequence the time setting can be increased. P51 should be set according to experience.

Recommended values:MOPX 213: 45 sec.MOPX 205, 207, 309 & 310: 30 sec.

N.B. If more than 100 secs is required for MOPX 205, or 140 seconds for the MOPX 207, 309, 310 & 213 this indicates a malfunction.

N.B. Before increasing the sealing water, make sure that the appropriate gravitydisc is fitted to the separator bowl.

N.B. This function is blocked in the clarifiermode (P2 = C, and P51 = - - -).

P52 Oil feed on during stabilizing periodOil admitted to separator bowl during astabilizing period.If more than 30 seconds is needed fothe purifier and 60 seconds for the clarifier it may indicate a malfunction.

6.3.2 Separation Sequence

P61 Time between sludge dischargesThe same as P1 (setting one paramewill set both to the same value).Bowl closing water is supplied for 2 seconds every 15 minutes.

N.B. In series operation the time sequencefor the clarifier must be longer than forthe purifier, in order to synchronize sludge discharges initiated from the purifier.1810108-02 V1 19

6 Additional Parameter Information MOPX Parameter List6.3.3 Sludge Discharge Sequence

P70 Displacement waterFilling of displacement water to the bowl eliminates the risk of oil loss at the next sludge discharge.If more than 40 seconds are required, this indicates a malfunction.

N.B. If P2 = C (clarifier mode), then P70 starts but the valve is not activated(i.e. no displacement water added).

P72 Sludge dischargeSludge discharge initiated by MV15 admitting water to the separator bowl.If more than 4 seconds are required, this indicates a malfunction.

P78 Draining of bowl operating system.Stabilizing period to allow water to drain from the opening chamber.Should be set according to experience.

6.3.4 Stopping sequence

P80 Bowl closing water onTo be set for proper closing of the bowl (on until P86)

P81 Bowl displacement water onPurifier mode only; the bowl is filled up in order to prevent vibration. MOPX 213 is 90 secs, and for smaller sizes 45 secs is recommended

P82 Oil feed onClarifier mode only; the bowl is filled up in order to prevent vibration.

The duration of the monitoring functions and output signals when the separator is operateclarifier is illustrated in the diagram.

1. Emergency Stop (XS2) is normally connected to terminal X8:4. If optional vibration switch (XS1) is installed it is connected to terminal X8:4 and the Emergency Stop (XS2) is connected to the system power supply.If the emergency stop button is pushed while the EPC is in stand-by mode the separator motor is stopped.

2. With optional sensor TT1 installed P50 will not start if the temperature is too low or too high.3. During P61 intermittently 1second every 5 minutes.
