1 Introduction

The PWB iModem is designed for remote data transmission for PWB-data loggers. Di󰀨erent protocols can be

used for data inquiry. The parameterization of the modem is done by the software PWB-Soft.

2 General safety instructions

• This device must only be installed and operated in compliance with the instructions and warning notices

of the dedicated technical documentation.

• Only qualied personnel must install and operate this device.

• The data logger‘s power supply is done by a lithium primary battery. This can optionally be done by a

power supply unit too. In this case the internal lithium battery supplies the data logger during temporary

power failure.

Please note the following safety advice before you install and operate the devices:

• The power supply units and batteries delivered by manufacturer must exclusively be used. Failure to do

so may result in severe damage and accidents.

• Please pay attention to intactness of all connection cables. If there are cable damages, put the device out

of operation immediately. Contact maufacturer for repair.

• Do not charge lithium batteries, throw them into re or expose them to heat, as this can lead to battery

explosion and result in personal injury and/or material damage.

• If uid from battery pack gets into your eyes, rinse them with plenty of water and see a doctor.

• Never use water to extinguish burning batteries! EXPLOSION HAZARD!

• Do not use damaged batteries!

• Do not short-circuit batteries!

• Mounting and connecting the device must only be done if there is no potentially explosive atmosphere.

• This device must only be used in areas with pollution level 2 as dened in IEC60991-1.

• This device is only suitable in areas with low risk of mechanical hazards.

• Connecting and disconnecting the plug connectors (antenne too) are only permitted if there is no explo-

sive atmosphere. Operating the moden without antenna is not permitted.

• Unplugged connectors are not permitted in hazardous areas. Always remove unplugged connectors from

hazardous areas!

• Opening the case (e.g. for battery change) must only be done if there is no potentially explosive atmo-

sphere.

• The case must only be cleaned by using wet cloths, otherwise there is the danger of spark ignition by

electrostatic discharge.

• The „online outlet“ for data transmission and data logger conguration must only be used in case of no-

nexistence of an explosive atmosphere. If not used, the „online outlet“ must be closed with the dedicated

cap.

• If the online outlet is permanently used, make sure that the connected devices are with voltage rating no

more than 60V AC or 75V DC. Furthermore make sure that there is a transient protection and that it is set

to a value that does not exceed 140% of the rated voltage.

Attention: The electronics consist of electrostatic sensitive components. Pay attention to ESD-

operation instructions when handling this electronics!

3 Special conditions for use in potentially explosive gas atmospheres of the zone 2

4 Special notes on antenna use in Ex zone 2

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

red by gas explosions.

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

na. 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 di󰀨erent antenna is supposed to be used in areas of the zone 2 endangered by

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

conducted by manufacturer again.

Operating manual of data acquisition system PWBlogg

• If the data logger is supplied by external voltage, the power supply unit delivered by manufacturer must

exclusively be used. This is always connected with the supply voltage outside of the explosion-hazard

area. Use the power supply unit only at the intended supply voltage. Supplying the data logger using

di󰀨erent power supply units and additional equipment is not permitted.

• If the device is equipped with a lithium ion battery, charging this battery must be done outside the poten-

tially explosive areas.

• For integration into the system‘s potential equalization use the dedicated port at the data logger‘s case.

Note: The data logger‘s battery circuit is operatively grounded at its case.

Any subsequent modication to the device results in the consequence that a secure use is no more

guaranteed within ex-zone 2 and the EC declaration of conformity loses ist validity.

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 the PWB-Soft.

• Adjust the interface in the dialog box „Connect“.

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

• Click on the „Connect“ button.

• When the connect dialog appears, adjust in the iModem eld to „automatic“.

• Connect the modem to the PC/laptop.

• To open the iModem dialog, click on the modem number in the main dialog.

• Click on the button „conguration“.

• Carry out all necessary settings. After conrming via „transmit“, the iModem will be congured again.

• Before you insert the SIM card, enter the correct PIN number to avoid disabling the card.

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 di󰀨erent options provided.

1. Battery:

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

BP16.5N5L is provided as standard since version iModem5 was introduced. This type supplies necessary

operating current for GSM/GPRS connection and has no e󰀨ect of passivation. The iModems as of generation

5 have built-in SuperCaps. The data logger battery type BP16.5N5 is used in this case 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 uninterruptible supply can be

ensured. A backup battery, however, ist not necessary for operating the modem. Any parameter, necessary

for operation, is 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 logger or ELS

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

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

dem3, 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

Status LED Modem LED

Status LED (green):

The status LED of the iModem ashes in di󰀨erent frequencies or is permanently illuminated to indicate the

current status of the iModem processor.

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

ted. 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 logger, sen-

ding 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 o󰀨 when the modem module is deactivated. As long as modem LED is o󰀨, no SMS can be sent

and no call can be answered.

A slowly ashing LED (iModem4/iModem5) indicates the modem is activated, but no call is active.

If an iModem6 is activated, the LED is permanently illuminated.

Quickly ashing LED (iModem4/iModem5): 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 o󰀨 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 o󰀨 after 5 failed attempts.

Operating manual of data acquisition system PWBlogg

The following applies to iModem4/iModem5:

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

After initializing the modem, shortly ashing LED and switching o󰀨 again indicates that faulty GPRS parame-

ters may inhibit successful initialization.

If, after modem activating, the LED illuminates 2s and turns o󰀨 again, then a wrong PIN or a disabled SIM

card can stop 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 (power supply unit/battery)

• 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‘s 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 (PIN OK or deactivated)

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/iModem5/iModem6 provide the status LED (green) and modem LED (red) on the housing co-

ver to make them visible without opening the device.

9 Charging the built-in accumulator (optional)

• Do solely use the delivered original charger for charging the accumulator.

• Make sure that the charger‘s specied input voltgage agrees with the local supply voltage.

• The used power socket must be accessible during the whole charging process.

• While charging, the temperature must be betwen +10°C and +45°C.

• The status LED‘s at the charger indicate the state (red = charging, green = charging nished) during char-

ging process.

• An entirely discharged accumulator needs about 3h charging time.

• The PC software PWB-Soft provides information on the residual accumulator capacity.

• To preserve the accumulator, you should switch o󰀨 the moden when it is not used for long. You ideally

store the modem with residual capacity of about 20%, but never with discharged accumulator.

Note: Depth discharge leads to permanent damage of the accumulator!

If the accumulator‘s residual capacity falls below 20%, it should be charged. We recommend 100% charge

before any use.

The accumulator must not be changed by the user. If a new one is necessary, forward the device to manu-

facturer.

8 Battery change

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

please not following procedure:

• A respective battery type including plug connector is available by manufacturer.

• Loose the four fastening cross-head screws of the cover plate.

• Loose carefully the plug connector of the battery and remov the old battery.

• Put the new battery in and press it on the dedicated Velcro pad (iModem3, iModem5, iModem6).

• Connect the new battery to the plug connector of the modem.

• Close the housing again without crushing connecting cables.

No data or parameters get lost when changing battery. After battery change, the modem will contact the log-

ger for the purpose of time synchronization.
