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 user-
programmable. 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).

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:

SLC-220 User Guide Rev 2.0 June 2018
16
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 Hazardous-
Area 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)

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
19
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
