1. Introduction

ComTroll® 333 Remote Terminal Unit (RTU) is designed for remote control and monitoring of

overhead line–and cable switchgear in the MV distribution network.

The unit it is also suitable as a general communication interface to other applications for

fault-detection and management such as earth-fault and short-circuit indicators and line

protection equipment.

ComTroll 333 communicates with the SCADA system through the ComTroll 120 GSM LON

Router using GSM Data (CSD) or SMS.

NorTroll offers a complete SCADA solution with NetTroll MicroSCADA Plug-in module for

configuration, control, monitoring and automation of the ComTroll 333 Terminals.

Control and monitoring

ComTroll 333 RTU must be programmed with a receiver number before it can dial up or send

any SMS messages. This is done during configuration and set-up.

Only one receiver number can be programmed into the device. This number is usually the

ComTrol 120 GLR telephone number.

ComTroll 120 GLR interfaces all GSM RTU devices in the network to the NetTroll microSCADA

system.

A status request can be sent to the ComTroll 333 RTU from a different number than the

primary receiver number (central unit) e.g. from a cell-phone providing a correct password.

In this case, the status will be sent back to the sender of the status request as well as the

primary receiver number.

By default, commands such as OPEN and CLOSE can only be executed on a GSM Data (CSD)

connection from NetTroll MicroSCADA. It is however possible to execute these commands

using SMS, but this feature must be activated in the configuration properties first and

incorporates a select-before-execute algorithm.

Commands (e.g. OPEN/CLOSE Switch) can only be done from the same number programmed

as the receiver number in the RTU. Any attempt to control from any other numbers will be

discarded even if the password is correct.

The ComTroll 333 RTU will periodically send its analog and digital status in a configurable

time interval. This mechanism is also called Heartbeat. If the heartbeat messages are not

received by the NetTroll microSCADA, an alarm will be raised to indicate a faulty device or a

bad communication link.

Any status change on the connected device (digital status) will be reported back to the

central unit without any polling/status request sent from the central. (Report-by-exception).

Analog status will be sent upon request from the central (or cell-phone providing a correct

password) or periodically (heartbeat).

Mode Selector

REMOTE: Local commands and indications are deactivated. Commands are only

executed when sent from the central unit.

OFF: Internal relays are disabled. No commands, either remote- or local are

executed.

LOCAL Local command buttons and LED indications are activated. Commands are

only executed when using the command buttons. Remote operation is

deactivated.

Communication is not affected by the position of the Mode Switch. It will therefore be

possible to send status requests and new configuration settings even if the Mode Switch is in

the OFF or Local position. Any change on the digital and analog status will also be sent back

to the central in OFF or Local position.

The Mode Switch must be in one of the three positions for more than 2 seconds before an

SMS is sent with the new position. E.g. if the Mode Switch is switched from REMOTE to

LOCAL, and the switch is in the OFF position less than 2 seconds, only the LOCAL position

message are sent.

Local Command buttons

The command buttons ‘Open’and ‘Close’are activated only when Mode Switch is in the

LOCAL mode. The buttons must be pressed more than 1 sec to execute the OPEN or CLOSE

command. The new status will be reported back to the central unit either as a SMS or CSD

connection dependent upon the configuration setting.

Hardware Setup

Preparing the SIM Card

The PIN code must be deactivated before inserting it in the SIM card socket. Insert it into a

cell-phone and follow the procedure explained in the cell-phone manual.

If the PIN code is activated when powering the ComTroll 333 RTU, the red ERROR LED will be

ON and the green NETWORK LED will flash. Normally, SIM cards can be provided without PIN

codes from the network operator.

Selecting the correct type of SIM card/subscription

We strongly recommend disabling voice feature on the SIM cards. Also, pre-paid SIM cards

should not be used for this application.

The SIM cards must be supporting CSD communication (GSM Data, 9600bps) and SMS. As the

telephone numbers are used as identification of the devices in the network, the Caller ID

(CLIP) service must be activated.

Inserting the SIM Card

Picuture 1; Mounting SIM-card and antenna.

The SIM card is inserted as shown in the picture above. Do not insert the SIM card when the

12Vdc power is connected.

Connecting the antenna:

The type of external antenna will vary upon the application and the mounting site. External

antenna must be ordered separately. The ComTroll 333 RTU comes with a short interface

cable that is fitted directly into the connector on the telephone module as shown in Picture

1: The ComTroll 333 provides 4 analog inputs. The four unipolar analog inputs offer

10 bit resolution, and may be individually programmed according to the incoming

signal. It can be set to 0 –10V (see note below for analog input 4) or 4 –20mA. The

inputs are read when the user executes a status request or when the ComTroll 333

sends any other message, e.g heartbeat.

Important notice

When the analog input 4 is set to read voltage, the range will be 0 -14,6V. This means

the battery voltage can be directly connected to this input to monitor the battery

voltage from the central unit. When the analog input 4 is set to current reading, the

range is 4-20mA. This means if analog input shall be used for other measurements

than battery voltage, 4-20mA setting must be used.

2: The Low Battery Input is a digital input that activates a warning message when the

input is shorted to GND. Please note that an external voltage relay must be used as

this is a digital input. This can also be used to monitor charging failure by connecting

a voltage relay with a signal contact to this input. The Low Battery warning is always

sent as an SMS to the central unit. To avoid warnings upon short voltage drops, the

SMS is delayed 60 sec.

If the normal battery voltage is restored within 60 seconds (or external charging is

restored) no message will be sent.

3: All of the 8 bipolar digital inputs are opto isolated and have the same physical layout.

However, the CLOSED and OPEN inputs have been assigned special functions in the

software, to make the unit suitable as a MV switchgear Terminal.

The user can define in the CONFIG command whether changes on the inputs are sent

as SMS or GSM Data, as well as sending updates on one or both transitions.

All inputs are Active Low, meaning the inputs are activated when shorting between

4 & 5: The normally open Relay 1 (OPEN) and Relay 2 (CLOSE) are dedicated to operation of

actuator relays. Relay 3 to 8 are general purpose normally open relays. The closing

time can be set by the configuration command. Maximum switching voltage/current:

200V/1A (AC and DC)

6: The serial port with RS 485 interface can be used to connect external secondary

equipment on the MODBUS protocol. Please note that not all versions of the

ComTroll 333 RTU have this feature implemented in software. Please contact

NORTROLL AS for details.

3. Functional Description

Configuration

There are several parameters that need to be set before the ComTroll 333 RTU can be put

into operation.

Set the receiver phone number.

Set operation mode

Set the heartbeat interval

Change the default password

Set relay timeout

Define the ITU standard

Activate two or four analog inputs.

Please keep in mind that changing the heartbeat interval to a short interval will increase

the operation costs due to the increasing number of SMS.
