Chapter 2 Installation
Power Supply Requirements
The SLM800S/1200S operate from an AC supply of 90 –260V or DC 12/24V.
All electronic products are susceptible to electrostatic shock, so follow proper grounding
procedures during installation.
The construction of the SLM800S/1200S can be mounted easily using the thread (3/4” NPT, 1”NPT ).
When choosing a location to mount the XDS800/1200(Sensor), bear in mind the following:
•For easy access to the LCD display and programming buttons mount it where it is easily
accessible.
•The ultrasonic signal path should be free of falling material and obstructions such as pipes,
beams etc.
•The XDS800/1200(Sensor) should be mounted at least 35/50cm above the maximum level
of the material and be perpendicular to the surface.
•The mounting surface should be vibration-free.
•The ambient temperature of the sensor is between -20ºC and 70ºC.
•There should be no high voltage cables or electrical inverters close by.
•Do not use any metal substances when installing
(Please use the PVC nut & flange supplied as option)

Outdoor and Open Vessel Installation
The XDS800S/1200S can be simply mounted on a bracket, suitable for the application and secured
using the thread located at the top of the transducer (3/4”NPT, 1” NPT).
Care should be taken to ensure that the XDS800/1200 are not installed in direct sunlight, in order to
avoid errors in the measurement of ambient temperature.
Attention should also be taken, when mounting the unit, to ensure that strong windy conditions are
avoided, wherever possible, to prevent abnormal operation.
Closed Vessel Installation
The XDS800/1200 can be simply screwed into a flange and secured using the thread located at the
top of the transducer (3/4”NPT, 1”NPT).
Where possible use a flange made of a synthetic material such as PVC, to avoid vibration
Place a rubber gasket between the flange and the connection to the vessel to avoid vibration.
Stand Pipe Installation
When mounting the XDS800/1200 to a standpipe care should be taken to ensure that the
standpipe is of sufficient dia with reference to its length, see the table below for details:
When using a standpipe, fixed to the top of a vessel, ensure that the open end of the standpipe is
clear of any obstructions such as weld seams, gaskets etc. in order to avoid unwanted signal
returns.
If using standpipes, which extend into the vessel, beyond the blanking distance, but not as far as
the empty level, then the open end of the standpipe should be cut to an angle of 45o.

Chapter 3 How To Use Controller
Operating the Controller
Display Window
SLM1000 is designed to display various data at the same time by adopting 40 letter LCD.
The display below shows an example of a normal operation of SLM1200S.
Conditions : The distance between the sensor and bottom of the tank : 12m
Current liquid level : 10m
1) L : 10.00 m : shows the current liquid level 10m
2) D : 2.00 m : shows the distance between the sensor and liquid level.
3) M : 86.9% : Percentage of the level
4) TEMP : Temperature around the sensor.
5) D : Indication of normal operation, shows returning echoes are well detected.
6) T : Indication of normal operation, shows tracking of returning echoes is okay.
7) S : No appearance under normal operation, but appears during abnormal operation
such as abrupt level change. Searching for the returning echoes.
