SLC-220 User Guide Rev 2.0 June 2018

The SLC-220 is designed for low-power consumption in onshore and offshore applications without an available power source. Therefore, the operating software extensively uses a “sleep mode” algorithm that turns off unnecessary hardware. Each monitored sensor is powered on for a short duration for sampling and decision making, and then turned off. This off interval is userprogrammable. Careful selection and programming of optional features will enable operation for months from a single battery charge.

All SLC-220 settings and calibrations can be changed locally or remotely through:

• Local LCD & touch screen or RS-232 connection to a PC with the SLC-Manager program (program supplied with a cable)

• Remote RS-485 connection to the control room through Modbus

• Remote cellular phone messaging if a Cellular modem is installed (SIM card required,

supplied by customer)

The Status of the system is available to the user locally on the LCD or with the SLC-Manager on the PC, or remotely at the control room through wires connectivity (Modbus) or wireless connectivity (Cellular / Satellite / Point-to-Point radio).

There are three types of SLC-220:

1. SLC-220/Multi, which supports up to four Leakwise sensors.

2. SLC-220/Basic, which supports up to two Leakwise sensors.

3. SLR-220, which supports up to four local sensor and multiple remote sensors connected to remote SLC-220 controllers.

2 Installation

Installation of the SLC-220 system includes three major steps. First, the sensors and the SLC-220 unit must be installed in their respective locations. Then, the interconnecting cables should be wired. Finally, configuration and calibration of the system components should be performed. Prior to the calibration procedure, fully install the sensor that has to be calibrated. Instructions and procedures for system configuration and calibration are described in the next chapters.

NOTE: For EMC compatibility, ferrites should be installed on the power and sensor/s cables.

Refer to Appendix D.

2.1 Sensor Installation

The sensors should be placed and installed in accordance with installation instructions specific to each type of sensor. Please refer to the appropriate Sensor User Guide.

2.2 Mounting and Wiring the SLC-220

The SLC-220 unit should be mounted in a dry, shaded location, and should have the inside of the enclosures easily accessible when opening the cover.

For a 100 - 240 VAC system, refer to the following SLC-220 Wiring Diagram: DWGW SLC 003 5. For a 12 / 24 VDC system, refer to the following SLC-220 Wiring Diagram: DWGW SLC 004 2. Refer also to mechanical drawings A SLC 0020, A SLC 0021 and A SLC 0030, and when applicable refer to the NEMA 7 / Exd enclosure drawing/s.

If Safety Barriers are required (hazardous Area installation) refer also to Appendix B in Sensor User Guide, to drawing DWGV2200012 that shows the summary of ITS certificate No. Ex01E2023.

The IP65 / NEMA 4 enclosure has a transparent cover with two latches on the right side and hinges on the left side. After opening the transparent cover there is access to the LCD with touch screen (if installed), installed on the front panel. Access to the boards and wiring connections is easy: Lift the front panel with a finger inserted into the hole on the right side of its edge (the hinges are on the left side).

SLC-220 User Guide Rev 2.0 June 2018

2.2.1 Connecting the Power Cable

Make sure that there is no power connected to the cable. Pass the cable through the electrical conduit that goes from the power source to the SLC-220. Pass the cable through the input gland on the bottom side of the enclosure.

For 100 - 240 VAC: Connect the cable to the power-supply terminal block inside the enclosure as follows:

Power Line Contact of Power Supply

Terminal Block

AC PHASE 1 (L) AC NULL 2 (N) FRAME GROUND 3 (FG)

NOTE:

Use wires of minimum 18AWG, specified to at least 90°C and 300V. An external switch or circuit breaker (5 Amp) must be installed on the power input line of SLC-220. This switch, located near SLC-220, must disconnect both poles of the supply voltage. It should be rated appropriately and must be marked as the disconnecting device for SLC-220.

For 12 or 24 VDC:

Connect the cable to the power-supply terminal block inside the enclosure as follows:

Power Line Contact of Power Supply

Terminal Block

+12 or + 24 V 1 (+) 12 V or 24 V RETURN 2 (-) FRAME GROUND 3 (FG)

Power consumption is 24 Watts maximum.

Note:

1. A Power On-Off switch is installed near the Power Supply terminal block for easier maintenance when power should be turned off before making wiring changes. The switch disconnects the 12VDC supply to the boards, not the Mains power!

2. When the SLC-220 is powered up, it goes through a self-test procedure of a few seconds which turns on all status lights. Only then the sensors are sampled normally and the lights, relays and 4-20mA outputs are updated to real values.

NOTE for SLC-220/Multi: If one or more Outputs Boards are provided, they are installed on a separate metallic mounting plate above the Main board. The mounting plate can be easily removed since it is fastened by four quick-disconnect nylon studs, giving access to the Main board. The nylon suds should be used gently to avoid break!

SLC-220 User Guide Rev 2.0 June 2018

2.2.2 Connecting Sensor Cables to SLC-220

Up to four sensors may be connected to the SLC-220. Each sensor is connected individually. The sensor wires are passed through the proper sensor cable gland in the external wall of the enclosure. Then they are connected to the respective contacts in terminal block TB10 (on Main Board) as follows:

Wire Color TB10 Contact Contact Function Red or Brown or Black#1 + Sensor +12 VDC (DET+)

Black or Yellow or Black#2 - Sensor GROUND (DET-) Blue, or Black#3 SIG Sensor SIGNAL (Iout)

Note: For EMC compatibility, a small EMC Filter board is installed as an extension to TB10.

Refer to Appendix D.

Main Board picture:

TB10 is on the right side

SLC-220 User Guide Rev 2.0 June 2018

Each sensor input has an indicating red LED on the board to indicate when it is energized. The LEDs are located on the left side of TB10.

For Hazardous-Area installation, connect the sensor through Zener Safety Barriers which are installed on an isolated DIN rail inside the enclosure. If the safety barriers are supplied with the controller, their Safe-Area side is already wired to TB10. Connect the sensors to the HazardousArea side of the safety barriers: Wire Color Safety Barrier Contact Contact Function

Red or Brown or Black#1 MTL 7715+ point 3 Sensor +12 VDC (DET+) Black or Yellow or Black#2 MTL 7715+ point 4 Sensor GROUND (DET-) Blue, or Black#3 MTL 7710+ point 3 Sensor SIGNAL (Iout)

SLC-220 User Guide Rev 2.0 June 2018

2.2.3 Connecting the Analog 4-20 mA / 0-5 V Outputs

Up to four Outputs boards may be installed in one SLC-220/Multi, up to two in SLC-220/Basic. The first board on SLC-220/Multi, located rightmost, is associated with sensor #1; the second board from the right is associated to sensor #2, etc. For SLC-220/Basic, the lower board is associated with sensor #1; the upper board is associated with sensor #2.

Outputs Board picture:

SLC-220 User Guide Rev 2.0 June 2018

If the SLC-220 unit is equipped with Outputs board/s, pass the 4-20mA cable through the proper cable gland in the external wall of the enclosure. Then connect the two wires to the contacts of terminal block TB19 as follows:

TB19 Contact Contact Function Iout 4-20 mA + (Current source, non-isolated)

GND 4-20 mA - (Current return, non-isolated) If 0-5 V output is required (instead of 4-20 mA), connect each of the two wires to TB19 as follows: TB19 Contact Contact Function Vout 0-5 V + (non-isolated)

GND 0-5 V return (non-isolated) Note: At this point, the current / voltage output is not galvanically isolated. Setting the functionality / range of the output is done by jumpers on the Outputs board:

JP5 position JP6 position Range at TB19

2-3 2-3 0-5 V 1-2 2-3 4-20 mA < This is the default setting 2-3 1-2 0-20 mA 1-2 1-2 0-24 mA

SLC-220 User Guide Rev 2.0 June 2018

Arranging the wires: For SLC-220/Multi, there is one white plastic wire saddle below each Outputs board. Insert the wires into the saddles and guide them to the left of the enclosure, then down and to the cable gland.

Note: If there is only one Outputs board and more than one sensor, and the Common functionality of the Outputs board is selected by setup, then the Analog output will be associated with sensor#1. Note: For a disabled sensor associated with an Outputs board, the 4-20mA output will default to

4.33 mA.

2.2.4 Connecting the Relay Outputs

Up to four Outputs boards may be installed in one SLC-220/Multi. The first board, located rightmost, is normally associated with sensor #1; the second board from the right is normally associated to sensor #2, etc. (See note 3 in 2.2.5 for exceptions).

SLC-220 User Guide Rev 2.0 June 2018

For SLC-220/Basic, the lower board is associated with sensor #1; the upper board (if installed) is associated with sensor #2. Pass the cable through the proper cable gland in the external wall of the enclosure. Then connect the wires of this cable to the contacts of terminal blocks TB14 till TB18 of the appropriate Outputs board as follows:

Relay number

Indicated Status

Terminal Block

Contacts

Water or Oil / High Oil for sensor #1

TB14

COM

Oil or Oil / High Oil for sensor #2

TB15

COM

High Oil or Oil / High Oil for sensor #3

TB16

COM

Air or Oil / High Oil for sensor #4

TB17

COM

Fail or Common Fail for all sensors

TB18

COM

NO: Normally Opened contact, COM: Common point, NC: Normally Closed contact.

Arranging the wires: In SLC-220/Multi, there is one white plastic wire saddle above every Outputs board. Insert the wires into the saddles and guide them to the left of the enclosure, then down and to the cable gland.

Each relay has an indicating LED on the board to indicate when it is energized.

The relays can be set to operate in normal mode or in fail-safe mode. Changing the setting is done in SLC-220 Settings (chapter 4.5).

SLC-220 User Guide Rev 2.0 June 2018

There are two modes to use the relays, depending on the setup:

1. Normal mode: Each sensor activates five relays on the relevant Outputs board. There is one relay associated with each status: Water, Oil, High Oil, Air and Fail.

2. Common mode: If only one Outputs board is installed, relay #1 will alarm on Oil / High Oil for sensor #1, relay #2 will alarm on Oil / High Oil for sensor #2, etc., and relay #5 will alarm on Fail in any of the enabled sensors. This results in individual Oil / High Oil indication and a common Fail indication.

Changing between the modes is done in SLC-220 Settings (chapter 4.5).

2.2.5 Adding / Removing Outputs boards, and Selt-Test

Up to four Outputs boards may be installed in one SLC-220/Multi. The first board, located rightmost, is associated with sensor #1; the second board from the right is associated to sensor #2, etc. The Outputs boards are connected in a series chain to the Main board which sends updated data to the relays and to the Analog output.

Outputs board #1 is connected by a flat cable from header J11 to header J6 on the Main board. Outputs board #2 is connected by a flat cable from J11 to J12 on Outputs board #1. Outputs board #3 is connected by a flat cable from J11 to J12 on Outputs board #2. Outputs board #4 is connected by a flat cable from J11 to J12 on Outputs board #3.

Note 1: Headers J11 and J12 on each board are actually in parallel; therefore, they may be interchanged in cases where it is more convenient, for example in SLC-220/Basic.

There are four jumpers on each Outputs board which must be set properly to ensure correct operation of the outputs. The setting depends on the total number of sensors and Outputs boards, and their position in the chain: For SLC-220/Multi, where additional Outputs board/s (up to 4) may be added at any time, the rightmost Outputs board in the chain will be associated with sensor #1 and will have address #1 (JP1 shorted, JP2, JP3, JP4 disconnected). Second Output board in the chain will be associated with sensor #2 and will have address #2 (JP2 shorted, JP1, JP3, JP4 disconnected), etc.

SLC-220 User Guide Rev 2.0 June 2018

Associating an Outputs board with sensor #1:

Note 2: Update the number of installed Outputs boards in SLC-220 Settings (chapter 4.5).

Note 3: In principle it is not important to associate a certain Outputs board in the chain to a certain

sensor in a rigid order. Note 4: It is also possible to associate more than one Outputs board to the same sensor! By

doing this, for example, two relays on different Outputs boards will give indications in parallel for the specific sensor status, and two 4-20mA outputs will give the same information for this sensor.

Note 5: An Outputs board associated to a disabled sensor will not operate: All relays will be deenergized, and all 4-20mA outputs will be set to 4.33 mA.

Outputs board self-test:

1. Power down the controller.

2. Remove the jumper from JP1 / JP2 / JP3 / JP4 of the Outputs board to be tested.

3. Power up the controller.

4. The relays will be energized and de-energized in sequence one after the other.

5. The 4-20mA output will change between 5mA and 10mA when a complete sequence cycle of the relays in finished.

6. Power off the controller.

7. Insert the jumper back to JP1 / JP2 / JP3 / JP4 (where it was before).

8. Power on. The Outputs board will operate normally.

SLC-220 User Guide Rev 2.0 June 2018

2.2.6 Front Panel Status Lights, On-Board Buzzer

There are six status lights on the front panel. The Power (green) light indicates operation of the unit. The other five lights can be used in either of two operating modes:

1. Common mode: Water (green), Oil (red), High Oil (red), Air (yellow) and Fail (yellow) lights will turn on if any of the enabled sensors (up to four sensors) generates the appropriate status. Therefore, it is possible that more than one light is turned on.

2. Individual mode: Oil 1 (red), Oil 2 (red), Oil 3 (red), Oil 4 (red) and Fail (yellow) lights will be operated as follows:

• Oil 1 will turn on when sensor #1 generates Oil or High Oil status.

• Oil 2 will turn on when sensor #2 generates Oil or High Oil status.

• Oil 3 will turn on when sensor #3 generates Oil or High Oil status.

• Oil 4 will turn on when sensor #4 generates Oil or High Oil status.

• Fail light is common to all enabled sensors. It will turn on if any of the four sensors

is in Fail status.

Therefore, it is possible that more than one light is turned on.

Note: Status of a disabled sensor will not be reflected in the status lights.

SLC-220 User Guide Rev 2.0 June 2018

The system is supplied in Common mode for systems supplied with a single sensor, and in Individual mode for systems supplied with more than one sensor. In order to change between

modes, if required, do the following:

1. Remove the existing Lights board from the front panel.

2. Remove the aluminum black Lights panel.

3. Install the black Lights panel inverted with the correct legends facing the user.

4. Install another Lights board (DWG S SLC 003 1) that has correct LEDs colors for the required mode (should be ordered separately). The serial number of a Common mode board end with a "C", while the serial number of an Individual mode board end with a "I".

5. Make the correct mode setting in SLC-220 Settings (chapter 4.5).

Lights Board picture:

SLC-220 User Guide Rev 2.0 June 2018

A new type of Lights board (DWG S SLC 003 2) will be installed during 2018. It supports both Common and Individual modes, therefore mode change will be very quick and easy. The board has JP11 MODE jumper to select between the modes. To use the Common mode, install the board with its’ right side above the black Lights panel. To use Individual mode, install the board with its’ left side above the black Lights panel.

New Type of Lights Board:

On-Board Buzzer:

Shoring jumper JP1 near the on-board buzzer (and TB6) enables the buzzer. The buzzer will beep one after a successful parameters update done through the LCD display or through the SLC-Manager PC program. It will beep multiple times if there are problems in the parameters, which will then be rejected.

SLC-220 User Guide Rev 2.0 June 2018

2.2.7 Connecting the RS-485 SCADA Serial Port

2.2.9 Connecting a PC to RS-232 Serial Port

A PC can be connected to the SLC-220 for setup, calibration and monitoring the sensors when required. The PC should have the SLC-Manager program installed to do this.

A RS-232 cable is supplied: Male to female, non-crossed Rx & Tx. Connect the 9-pin male DSubminiature connector to connector J9 on the Main board, as follows:

J9 Contact Contact Function (SLC-220 side) 2 RxD (Data input to SLC-220)

3 TxD (Data output from SLC) 4 DTR (Input, Data Terminal Ready from PC) 5 GND (and shield of RS-232 Cable)

Connection of PC DTR to pin 4 is essential to enable automatic detection of a device connected to this port.

For a PC without a RS-232 connector, a RS-232 to USB adaptor is also supplied.

For IP65 / NEMA 4 enclosure of SLC-200/Multi: Connect the PC to an extension connector located at the top-left of the opened enclosure, and marked "PC".

For IP65 / NEMA 4 enclosure of SLC-200/Basic: Connect the PC to an extension connector located at the right of the opened enclosure, and marked "PC".

For Exd / NEMA 7 enclosure: There is a "PC" connector located under the glass window. This enables easy connection of a PC without the need to open the screws of the enclosure.

The communication through this port is in Modbus protocol with a fixed address 1. Therefore, a SCADA can be connected to the RS-232 port if required. The port is set to a fixed 115,200 Baud, 8 data bits, 1 stop bit, no parity, and no flow control.

Note: The PC and the SCADA share the same serial port on the SLC-220 Main board. When a PC or any other terminal is connected to the RS-232 port, the RS-485 SCADA port is disabled within 10 seconds after the SCADA confirms this event. This is required since the SLC-220 acts as a slave device, and can handle only one master device at a time: PC or SCADA.
