The CIM 250 is fitted with a lithium-ion battery. It is secured by
a velcro strap which absorbs vibrations and makes it easier to
replace the battery. Connect the battery to the CIM 250 as shown
in fig.
.
Fig. 5
Connecting the battery
Switch on the power supply. The CIM 250 is powered either by
the CIU 250 or by the battery.
The LED1 is flashing yellow (searching for GSM network).
When the connection to the GSM network has been established,
the LED1 will pulsate yellow (GSM network active). See fig.
The LED2 must be constantly green, indicating that the CIM 250
has been fitted correctly in the CIU 250.
3.1.4 Configuration
For software configuration of the CIU 250, which includes setting
of SMS functions and SCADA communication parameters, see
"CIM 25X SMS commands" (supplement to installation and
operating instructions) on the CD-ROM supplied with the GSM
module.
Warning
The CIM 250 must only be connected to SELV or
SELV-E circuits.
Warning
The safety precautions listed below must be
observed carefully as improper handling of the
lithium-ion battery may result in injury or damage
from electrolyte leakage, heating ignition or
explosion.
Note
If the battery is not connected, the user will not
receive any SMS alarm message in case of
a power cut.
