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.
