Storage and Handling

The Point Orange has an internal lithium thionyl chloride (LTC) battery pack. This is a mature proven

primary lithium battery technology that has been deployed globally to power millions of devices. The

manufacturer of the cells used in Point Orange have an exemplary track record and excellent design

and quality assurance. These cells are used in many industries and have been certified to all relevant

standards.

However, as with all lithium batteries, it is important to follow the manufacturers recommended

guidelines for handling and storage. These guidelines are repeated below for convenience and are

subject to update by the cell manufacturer. Please contact Metasphere if you require any further

information about the lithium battery pack used on Point Orange.

WARNING

This equipment contains lithium thionyl chloride batteries which must

not be short circuited, punctured, crushed, deformed, recharged or

exposed to water, moisture or high temperatures. Batteries should not

be removed from this housing.

Replacement packs are available from Metasphere Ltd.

Storage

Store in a cool, regulated (preferably below 21°C and in any case below 30°C), dry and ventilated

area, away from possible sources of heat, open flames, food and drink. Avoid exposure to direct

sunlight for long periods.

Temperatures above 100°C may cause leakage and rupture, and result in shortened battery service

life. Keep proper clearance space between batteries and walls. Since short circuit can cause burn

hazard, leakage or explosion hazard, keep batteries in original packaging until use and do not mix

them.

Handling

■Do not open the battery system.

■Do not crush or pierce the cells.

■Do not short (+) or (-) terminal with conductors.

■Do not reverse the polarity.

■Do not submit to excessive mechanical stress.

■Do not mix batteries of different types or mix new and old ones together.

■Do not use the unit without its electronic management system.

■Do not expose the unit to water or condensation.

■Do not directly heat, solder or throw into fire. Such unsuitable use can cause leakage or

spout vaporized electrolyte fumes and may cause fire or explosion.

Point Orange User Guide

Point Orange Overview

Point Orange is a compact Logger/RTU device with integrated battery, quad band GPRS/GSM modem

internal and external antenna options, flexible IO, and an integrated submersion sensor.

Point Orange is part of the Point Colour product range, which also comprises Point Green and Point

Blue.

The key functions of Point Orange are:

■IP68 enclosure, suitable for submersion to 4m for 4 days

■Integrated installation bracket offering a range of mounting options

■Up to 5 programmable external IO channels, allowing over 100 possible combinations of

analogue inputs, counters and digital inputs

■Internal submersion sensor –to detect when the unit is submerged under water

■Communicates with either Medina or DNP3 Master via a quad band GSM/ GPRS modem or

combined Tri-band 3G and quad band GSM/GPRS modem

■Internal antenna and optional external antenna with Automatic antenna selection

■Internal lithium battery pack for long life

■Provision for connecting an external DC supply or battery pack

■Local diagnostic points such as GSM signal strength, temperature, battery voltage

Basic functionality

The Point Orange is an intelligent Remote Telemetry Unit (RTU) that allows the user to monitor

signals from a wide variety of sensors. The data read, can be logged at regular intervals, (Trending),

log when a particular event has occurred, (Events), or report by exception if an urgent message

needs to be reported (Alarms).

Data can be stored using the onboard memory, and reported using either DNP3 or Medina protocols

to a server using the internal quad-band GSM/GPRS modem or a tri-band 3G modem.

External connections

The Point Orange has 2 external connectors; the first is the main connector at the front, which is

used for connecting external sensors and/or the USB cable for configuring or monitoring the RTU.

Point Orange User Guide

The second connector is the external antenna connector that allows for a second antenna for use in

areas of poor GSM network coverage.

Configuration

Before using Point Orange, it needs to be configured using one of the Poco configuration tools

available from Metasphere. Poco is a Windows based application that allows the user to specify how

the Point Orange should operate. For more information on Poco please see the relevant user guides.

The Point Orange should be connected to the PC running Poco using the Point Orange configuration

cable which connects to the main connector on the Point Orange and a spare USB port on the PC.

External IO

The Point Orange has 5 IO channels; these are provided through the single main connector on the

front of the unit. The function for each of these channels is controlled by software and is configured

using one of the Poco configuration tools.

The options for each channels includes Analogue Inputs (AI), Counters (CI) or Digital Inputs (DI). The

exact options will vary depending on the configuration selected, for example, the unit is limited to

supporting 2 active loop analogue inputs. However, given the flexibility of the various channels, over

100 IO combinations are possible.

Modbus

The Point Orange can operate as a Modbus master capable of reading coils and registers on a

Modbus slave and record these values as DNP3 digital, analogue or counter points. The Point

Orange can communicate with a Modbus slave via RS232 or RS485 (half or full duplex) using

specially designed cables (part numbers 5-136, 5-137 and 5-138) connecting to the main connector.

Internal Points

In addition to the external sensors the Point Orange has a number of internal points that can be read

by a master station such as battery voltage, ambient temperature, or whether the unit is submerged

or not. These conditions are mapped to points and are always available, and can be logged by the

RTU as required.

Modem

The Point Orange has two build options, Point Orange and Point Orange 3G. The first will support 2G

network technology (GSM/GPRS), while the second version, will support a 3G network technology

falling back to GPRS when 3G isn’t available.

On reset the Point Orange will automatically detect which modem is connected and use the

appropriate modem commands.

Point Orange User Guide

Points

The Point Orange has a fixed list of points built into the firmware. These points are available to be

read by the telemetry master, or can be monitored using one of the Poco applications. A complete

list of all available points is provided in the Point List.

What follows is a description of the points available, including what they are and how they are

updated. To ease navigation, they have been broken into 2 sections external and internal points,

before being split further by function. In general all points are advertised as analogue inputs,

counters, digital inputs and string points.

The first 5 points for AI, CI and DI are reserved for external IO. All of these points are always in

existence; however, these points will only register values if configured in the Poco application IO

screen. If the IO points are not configured in a Poco application, and the points are read by the

telemetry master, the values will be fixed at zero.

Internal points are always present in the configuration of the Point Orange and can be read as

required by the telemetry master.

Analogue points are provided with the raw value range, and the equivalent engineering units for

each end of the range. This indicates the possible raw values of the point, and the suggested values

for configuring the master station’s engineering scaling conversion factors.

Updating point values

The Point Orange has been designed with the principle of conserving power. As a result, the point

values are only updated when the RTU is awake. So for example, if the highest frequency trend

configured on the RTU is 15 mins, then the point values will only be updated at this frequency, as

the RTU is asleep in between these samples.

There are three exceptions to this rule;

■When the USB is connected

■If an alarm is configured on an analogue input

■Digitals and counters

When the USB is connected to the Point Orange, the RTU will not go to sleep, as the assumption is

that the user is configuring the RTU or wishes to monitor the point values as they are updated. In

this instance, all non-loop powered points are updated continuously on a 2 second cycle.

In addition to this it is possible for the Point Orange to be configured to keep the loop supply

switched on if the USB is connected at boot up. After the configured sensor settle time, the sensor

will be continuously sampled at the quickest update frequency until the USB is disconnected. After

which the loop supply is turned off and will revert to any configured trend period frequency. This

feature is useful when installing the Point Orange in the field to verify that the sensor readings are

accurate. This feature is called ‘Sensor Validation’ and can be activated by selecting the check-box in

Poco.

WARNING

Connecting the Point Orange to the PC using the USB cable will leave the

Point Orange on for the duration of the connection. This will drain the

battery and long periods of connection should be avoided.
