1 Introduction

The PWB-iModem is designed for remote data transmission for PWB-data loggers (ELS, PWBlogg).

Different protocols can be used for data inquiry. The parameterization of the modem is done by the

software PWB-Soft.

2 General safety instructions

The power supply of data measure- and storage devices is provided by mains adapter. Some de-

vice alternatives can also be supplied by lithium battery. Please consider following notes on safety

during operation of the devices:

• Use no other mains adapters and no other batteries or battery packs as supplied by manu-

facturer or recommended ones, otherwise it can lead to serious damage of the device and to

accidents.

• Avoid mechanical damages of the electric cable of the mains adapter, as these can cause re or

electric shocks. Do not use damaged electric leads anymore.

• Do not recharge battery or battery pack or throw them into re or expose them to great heat,

as this can lead to an explosion of the batteries and can cause injuries to persons or material

damages.

• If a liquid of the battery pack reaches your eyes, rinse them immediately with a lot of water and

see a doctor.

Attention: The electronics consist of electrostatic sensitive components. Pay

attention to ESD-operation instructions when handling this electronics!

3 Safety instructions for use in Ex zone 2

The iModem is deliverable as operational supplement falling in category II 3 G for safe use within

explosive gas atmospheres of zone 2.

Please, pay attention to the following note on safety:

• The „online-outlet“ for data transfer and conguring iModem or data logger must be installed

outside of the explosion-hazard area. If the ‚online-outlet‘ is at the modem housing, this outlet

must only be used in case of nonexistence of an explosive atmosphere. When the system is not

used, the „online-outlet“ has to be closed using the protective cap.

• Devices must only be used with rating no more than 60V AC or 75V DC voltage, which prevent

the exceeding of rating even if a temporary interference of more than 40% occurs.

• If the iModem is supplied by external voltage, the mains-plug power supply delivered by manu-

facturer must only be used. This is always connected to the mains outside of explosion-hazard

area. Do only use the AC-adapter at the mains voltage to be designed (230 VAC). Power supply

by using different mains adapters or accessory units are inadmissible.

• Opening the iModem e.g. for battery change must only be done outside of the explosion-hazard

area (in case of nonexistence of an explosive atmosphere).

• In case of damaged cables (data, transducer or ac power line), the device must not further be

operated. Please ask manufacturer for purpose of a repair.

• The antenna of the iModem is generally tted outside the Ex zone.

• Allsubsequentmodicationstothedeviceresultintheconsequencethatasecureuse

is no more guaranteed within Ex zone 2 and the EC-declaration of conformity loses its

validity.

Operating manual of data acquisition system PWBlogg

• The ANT2-M is an antenna which is applicable when using a PWBlogg iModem in zone 2 areas

endangered by gas explosions.

• Please note: The ANT2-M is classied as „simple apparatus“ as there is no ignition risk just by

the antenna. Therefore ATEX markings are not permissible.

• The ANT2-M has been assessed together with the PWBlogg iModem to ensure that there is no

ignition risk by interconnecting both.

• If the iModem including a different antenna is supposed to be used in areas of the zone 2 endan-

gered by gas explosions, the antenna must be installed outside any dangerous area or a risk

assessment must be conducted by manufacturer again.

5 Start-up instruction

Please, consider following references during initial operation of the modem:

• Initially, install the software PWB-Soft

• Connect the iModem to power supply

• Then connect the iModem to PC by means of data cable for online-connection.

• Start PWB-Soft

• Adjust interface in the dialog box „Settings“.

• Open “iModem” dialog in the menu “Module”

• Establish connection between PC and iModem via „Read parameters“.

• Carry out all necessary settings. After conrming via „Write parameters“, the iModem will be

congured again.

Please note when using iModem with separate ELS and data logger:

• The module time (important to time slot) is taken from ELS/data logger.

Please not when using iModem with internal ELS:

• The module time must be adjusted via ELS software. It is important in particular regarding set-

ting of time frames!

Please note when using GSM-modem:

• Before inserting SIM card, the correct PIN-number must be adjusted to avoid blocking the card!

Please note when using iModem5:

• The internal jumper on activating/deactivating the built-in SuperCap must be switched to the

position On

• Charging the SuperCap at initial operation can take up to 12 hours. Meanwhile any modem

features (in particular data uploads, e-mail dispatch etc.) are available to a limited extent as the

case may be.

• When not using the modem for a long period (storage), please remove the battery and switch

the jumper to the position Off.

6 Hardware iModem

The iModem is delivered in aluminium-form housing with degree of protection IP 65. A xed online

cable provides connection to a data logger. Depending on online port type at the data logger, an

infrared or R232 interface is provided. PC connection to data logger and iModem is done via online

port of the iModem. A correct power supply must be provided for connection to a data logger or to

an iModem respectively. For this purpose, there are different options provided.

1. Battery:

The modem can be equipped both for bypassing power failure periods and for power supply only.

The battery BP16.5N5PP is provided as standard. This type supplies necessary operating current

for GSM/GPRS connection and has no effect of passivation. The iModems from generation 5 have

built-in SuperCaps. The data logger battery type BP16.5N5L is used here too.

2. External voltage:

Depending on type, the modem can be supplied with external voltage between 12 and 14 volt.

Normally, the device is operated by a 12 V mains adapter. Combined with a lithium battery, an un-

interruptible supply can be ensured. A backup battery, however, ist not necessary for operating the

modem. Any parameters, necessary for operation, are saved in non-volatile memories. Date and

time are taken from connected data logger.

3. Accumulator:

Power supply for mobile applications is also possible by accumulator (separate manual).

The reasonable adjustment of time slots allows economical operation of devices and long battery

life. On request, a life estimation will be made by the Paul Wegener GmbH.

The previous gures show the iModem with lithium battery to supply it. Before operating the GSM

modem, the correct PIN number of the SIM card must be adjusted via iModem-software!

The online-connection is on the right. It is used for connection to the integrated or external data log-

ger or ELS and for making the iModem settings. The antenna is located above at a GSM modem.

Insert SIM card, iModem3: iModem4: iModem5:

Before connecting GSM modem, the SIM card must be inserted into the modem. For that purpose,

on iModem3, you must open the cover of modem-housing. The SIM card slot is located on the GSM

module and can be opened at an eject button using a small pointed item. The iModem4 provides

the SIM card slot under the battery holder. Please insert the SIM card as shown in the photo. After

the SIM card has been inserted, the modem can be closed again and is ready for operation.

7 Status indication

The modem‘s operational status is indicated by two on the enclosure cover mounted status LED‘s

(iModem4 and iModem5 only).

Status LED (green):

The status LED of the iModem ashes in different frequencies or is permanently illuminated to indi-

cate the current status of the iModem processor.

If the online cable is plugged, the permanent activated status LED indicates that the modem pro-

cessor is ready to receive commands from PC/laptop. If the online cable is plugged and the LED

ashes, that means the iModem is performing a task (data transmission, modem initialisation etc.)

and not ready-to-receive!

Flashing in 2,5s pulse: The iModem has recognized the connected data logger. The processor is

at sleep mode.

Flashing in 1s pulse: The iModem has not recognized the connected data logger or no data logger

is connected. The modem searches every 30s for the logger.

Quickly ashing in 0,25 pulse: The processor of the iModem is busy (eg searching/reading the log-

ger, sending SMS etc.)

Flashing in 0,5s pulse: The iModem has recognized a call or established connection to a receiver.

Online is not possible now.

Modem LED (red):

Status display of the modem:

This LED is off when the modem module is deactivated. As long as modem LED is off, no SMS can

be sent and no call can be answered.

A slowly ashing LED indicates the modem is activated, but no call is active.

Quickly ashing LED: A call has been recognized and connection is established.

LED permanently on: The modem is activated, but still has no connection to mobile service provider.

If the LED illuminates permanantly only for some seconds, turns off and illuminates permanantly

later again, faulty settings might make errors when initializing the modem. Hence the modem can

not be activated and will be switched off after 5 failed attempts.

If the LED illuminates permanently, problems on reception are indicated.

After initializing the modem, shortly ashing LED and switching off again indicates that faulty GPRS

parameters may inhibit successful initialization.

Status-LED Modem-LED

If, after activating the modem, the LED illuminates 2s and and switches off again, a wrong PIN or a

cancelled SIM card may inhibit initialization.

Assistance on knowing problems:

1. The modem does not activate itself:

• examine ashing behaviour of the modem LED of the modem

• check power supply

• check PIN of the SIM card

• check reception

• check time slot

• make sure that the data logger is connected (modem adopts time from logger)

2. SMS are not sent:

• check, whether the respective event is activated and a receiver is specied (activating SMS or

alert SMS),

• the modem will be activated,

• a PC is connected, which inhibits communication to the modem,

• when using N7 data loggers: check, whether the event “send SMS” is specied as alarm event,

• whether power supply is ok,

• whether the SIM card is unlocked

3. The modem can not be called:

• check, whether a time slot is specied and the modem is activated,

• the right call nummer is used (data call number)

• the SIM card is eligible for data calls,

• a PC is connected to the modem which blocks calls,

• the modem of the receiver is eligible for calls and its settings have been properly made

4. The modem does not write into the web database:

• check, whether the modem is specied as GPRS modem,

• the dedicated rmware is used,

• GPRS parameters are correct,

• FTP transfer is activated (time slot 15min or 1h)

5. The modem does not send data mail:

• check, whether correct SMTP parameters are specied,

• GPRS parameters are correct,

• the modem is specied as GPRS modem,

• a mail address is entered as receiver (eg event time slot)

The iModem4 additionally provides the status LED (green) and modem LED (red) on the housing

cover to make them visible without opening the device.

8 Battery change

Werecommend battery change shouldbe done by manufacturer.If you change battery by
