2 PRODUCT DESCRIPTION
The wireless transmitter series EE240 combines modern sensor technology, easiest system installation
and the highest reliability of the data transmission. The several different modules of the series EE240
are within a short time operational.
2.1 Wireless Network
2.1.1 General
The series EE240, based on the “ZigBee” protocol, transmits at a frequency of 2.4 GHz with a power of
6,3 mW. A bi-directional wireless connection prevents loss of data, if disturbances may occur.
The maximum transmission distance depends greatly on the local conditions. Obstacles, like walls of
reinforced concrete, steel buildings, or structures attenuate the signal and decreases the transmission
distance.
5
Operating manual Series EE240 Wireless sensor

2.1.2 Installation of a wireless system
In principle, in an ideal situation, the transmitter and the router resp. the base station should be within
‘eyesight’ to achieve an optimal strength of the signal. If that is not possible, a more appropriate location
can be found using the features of the base station EE242, with the support of an amplifying router. The
changes of the strength of the transmitter signal are indicated in a percentage (%), by the signal indica-
tor on the web server of the EE242.
If obstacles interfere with radio communication between the transmitter and the base station, routers
can be used to circumvent these obstacles and extend the distance between the transmitter and base
station. A "series connection" of routers is possible without any problems.
Optimal positioning of a router:
• To reduce cost several different transmitters can be channeled over one router.
• The router should always be aligned with the weakest transmission connection.
• A maximum of 10 wireless connections per router / base station; see outline 2.1.3.

For details refer to chapter 3.2.3 Operating components (Transmitter).
4 STARTING UP THE WIRELESS SYSTEM
4.1 Necessary Steps to Start up the System
For the conguration of the EE242 a personal computer is needed (with admin authorization), to
manage all transmitters and to congure the analogue outputs of the base station.
1. Preparing the hardware:
Attention: the base station can handle a maximum of 10 wireless signals (transmitter or router). If
more than 10 transmitters are needed, an extra router will extend the network further (for details, see
chapter 3.3. Router).
2. Establish the power supply to the base station.
3. Connect the sensing probe to the transmitter, either direct or with a sensor cable.
4. Establish the power supply to the transmitter 4 x 1.5 V, AA/LR6 alkaline batteries
(not in the scope of supply).
5. Establish the wireless connection: Press the push-button “Connect” for 3 sec.. Immediately the base
station switches to the ‘Connect-Mode’ and searches for active transmitters – for 30 sec.. The LED
next to the push-button lights up to indicate the ‘Connect-Mode’ is active. Within these 30 sec., the
push-button “Connect” on the transmitter must be pressed for 3 sec. to establish a connection. As
soon as the base station recognizes the wireless signal from the transmitter, the addresses of the
devices are automatically exchanged and the wireless connection established.
6. Checking the active wireless connection:
Base station: The wireless connection is active, as soon as the measurement data is available
(display, analogue output).
Transmitter: The wireless connection is active, as soon as in the display the symbol >< is
continuously illuminated (see chapter 3.2.3. Operating Components, under 3. Display).
7. Alterations of the conguration of the transmitter: The transmission interval is set at a default of 5
minutes. To increase the operating life of the batteries the transmission interval can easily be altered
with the rotary switch “TIME” in accordance with the interval-time table, see chapter 3.2.3 Operating
Components, under 1. Rotary Switch “TIME”.
8. Preparing the personal computer:
- PC with admin authotization, no disk space is needed on the personal computer, because the
EE242 is equipped with a web server.
- crossover cable (PC-EE242: HA010333) for connecting directly with the EE242 or Switch and two
network cables.
14
Operating manual Series EE240 Wireless sensor

9. Conguration of the wireless network:
Connect the base station with the personal computer by way of the Ethernet connection and adjust
the network settings (see chapter, Conguration Software).
- Start the internet browser (Internet Explorer, Firefox, ….).
- Enter the default IP-address (//192.168.0.64) of the EE242 in the address line.
10. Changing the conguration settings of the transmitter and the base station, see chapter Congurati-
on Software.
4.2 Increasing the Transmission Distance with Routers
In order to register the transmitter EE244 to the network through the router the following steps have to
be taken:
a) Register the router:
Press the push-button “Connect” on the base station for 3 sec.. Within 30 sec., the push-button “Con-
nect” on the router must be pressed for 3 sec. to establish a connection. As soon as the base station
recognizes the wireless signal from the router, transmitters can be added and connected through the
router.
b) Register transmitters to the network through the router:
Press the push-button “Connect” on the base station for 3 sec. Within 30 sec., the push-button “Con-
nect” on the transmitter must be pressed for 3 sec. to establish a con-nection. As soon as the base sta-
tion recognizes the wireless signal from the transmitter, the addresses of the devices are automatically
exchanged and the wireless connection established.
4.3 Parallel Operation of Several EE240 Wireless Networks
Each wireless network is built around an EE242 base station, and depending on the number of trans-
mitters, may include one or more EE244-R routers. For the parallel operation of several EE240 net-
works at one site it is of paramount importance for each transmitter and router to be within the
transmission range of the routers and basis station of only one network.
Very important:
A transmitter may not be located in the transmission range of basis stations or routers from two different
networks. Failure to comply with this disorganizes the networks and leads to critical failures.

Accessories).
5.3 Functional Test of the Entire Measurement System
It is possible by utilizing reference probes (xed output value) to test the
entire measurement system. A reference probe, available as an accessory
(incl. calibration certicate / see chapter 8. Replacement Parts / Accesso-
ries), is used to test the function and accuracy of the measurement loop.
Both reference probes, with a xed output value for humidity and tempera-
ture, are connected to the transmitter instead of the standard interchange-
able sensing probes. The reference probes simulate a high humidity and a
low temperature value and vice versa, in order to test the high and low end
of the scales of the analogue outputs.
5.4 Loop-Calibration
The loop calibration of the humidity and temperature outputs, as recommended by the FDA for the phar-
maceutical and biotech industry, can easily be realized with separate humidity and temperature sensing
probes (type EE07). E+E’s “Humor 20” can be utilized as the high accurate humidity calibrator (see
chapter 8. Replacement Parts / Accessories).

6 TROUBLESHOOTING / MAINTENANCE
6.1 Replacing Sensing Probes
If a sensing probe is damaged (e.g. mechanically damaged,...), the user can replace the probe with
a new one without any adjustment of the transmitter. This way an elaborate process of returning the
equipment to the factory will be avoided.
Procedure to replace a sensing probe:
1. Remove the faulty sensing probe.
2. Connect the new replacement probe.
3. In addition, the webserver of the base station EE242 offers the possibility to manage the sensing
probes (see chapter Conguration software).
6.2 Troubleshooting
Error
• possible cause → Action / Correction
Sensing probe measures incorrectly
• Error during recalibration of the transmitter → Reset to default factory settings and repeat the
calibration procedure.
• Filter cap dirty → Replace lter cap
• Sensor faulty → Replace sensing probe
Long response time
• Filter cap dirty → Replace lter cap
• Wrong lter cap → Replace with suitable lter cap for the application.
Transmitter failure
• Interrupted power supply or weak batteries → Check the wiring of the power supply resp. test the bat-
teries. If the batteries are replaced within 7 days after the failure, the system will automatically restart.
If the batteries are replaced after 7 days, it sufces to press the push-button “Connect” at the base
station to restore the connection.
Too high humidity value
• Condensation at the tip of probe → Dry out the probe tip and check if the probe is mounted in the
correct way.
• Wrong lter cap → Replace with suitable lter cap for the application.
Failure of the wireless connection
• Interrupted power supply or weak batteries → Check the wiring of the power supply resp. test the
batteries.
• New erected obstacles (metal structures …) attenuate the wireless signal → Bypass the obstacles
utilizing additional router(s).
Forgot password
• → Reset the base station E242 to the default factory settings (IP- address, Password,.) see chapter
3.1.5. Network Reset.
