building and the advice is to use extinguishers type D, Lith-X, DO NOT USE WATER in case of battery leakage
Special hazards: irritating vapour
Special protective equipment: wear protective clothing, use self-contained breathing apparatus with filtered
cartridge type ABEK
Leakage measures
In case of break of a battery, all the people must go away from the place where the incident happened and
come back only after the dissolution of the irritating gas.
Broken batteries or battery packs must be covered with sodium carbonate (Na2CO3) or dry sand, place them in
approved container and dispose in accordance with local regulation.
Disposal
Please return batteries to Powelectrics for disposal. Ensure suitable packaging in used. Do not use air freight.

2Introduction to the Metron 2
2.1 How to install, setup and commission the Metron 2
If you are new to the Metron 2, the following basic process must be followed:
1. Read through the remainder of the introduction to the Metron 2
2. Mechanically mount and understand how to seal the Metron 2 (section 3.1)
3. Electrically wire in the Metron 2, observing requirements (section 3.2)
4. Fit SIM card

If you are experiencing problems with the Metron 2, please refer to the troubleshooting guides and FAQ. If you
still require support, please look at the checklist below (2.2) and contact your distributor, or Powelectrics if
purchased directly.
2.2 Requirements for Technical Support
Please note that if you wish to contact us for technical support setting up a unit, before we can help you we will
need some information from you.
Necessary:
Serial Number
SIM card information
Access to the unit and its physical location
What you would like the Metron 2 to do
Information about the sensors or inputs into the Metron
Ideally:
An exact configuration you would like
A laptop or computer with the software running
A mini USB cable
A multi-meter
Specific part numbers for the sensors or inputs to the Metron
A SIM card that you have sent a SMS message from using a normal phone (important!)
2.3 Overview
This document describes all the functions, features and interfaces of the Metron2 telemetry device.
Applications
A few of the applications that this device has been designed for include:
Remote Tank Level Monitoring
Environmental Monitoring
Meter Reading
Condition Monitoring
Alarm Reporting
Summary of Technical Features
Ability to interface with up to four analogue (0-10V or 4-20mA), digital (ON/OFF)
On-board excitation, 3.6 volts (non-regulated), 5 v, or 21.6 volts (max 31.25mA)

9
Internal battery powered with a long life, or external 6 to 24 V DC power source (0.5 amps).
Back lit LCD Display, 40 x 40mm, 128 x 128 pixels, to help with on-site setup & diagnosis
Quad-band operation
USB port for programming & firmware upgrade.
Expansion board socket for future use.
As the Metron2 is normally a battery powered device it has been designed in such a way to extend this life to a
maximum. This means during normal operation the display will be off, the sensors excitation will be off and the
GSM engine will be powered down. As required these are switched on by the processor and when finished with
they are switched off. If the unit is powered from an external source then the unit can be configured so that the
GSM engine is always on.

All dimensions in mm.
Open the lid to reveal the 2 mounting holes. These should be used to fasten the Metron 2 down to a baseplate,
wall or other surface. To access these two holes, you may have to remove two M12 blanking plugs. These
must be replaced.
The two screws on the front of the enclosure should not be over tightened –otherwise it is possible to break the
watertight seal by tearing or deforming the ‘O’ ring below the head of each screw.
The unit needs a mobile phone signal to work –the stronger the signal the better so try and avoid mounting
inside metal cabinets or underground. Mounting it on the outside of a metal container may help improve the
signal, depending on the direction and location. Use the ‘Get config / signal’ feature to find the optimum location
first.
Weatherproofing Information
It is essential that the following is checked if being used outdoors
All cable glands and breather glands on the unit should have an ‘O’ ring fitted and are sufficiently
tightened
Both screws on the top are tightened, but not over tightened
The seal around the lid is correctly in place
