IE-LOG-S0842-01 9
Warning: near battery fragile glass reed contact is located – be careful not to damage it. Be
careful in battery replacement!
Replacement procedure:
switch off the logger by the PC program or by magnet (if low battery allows)
unscrew four corner screws and remove the lid
remove old battery by pulling the glued tape
insert new battery respecting the correct polarity (see s and – near battery holder). If
you connect new battery up to 30 s, all logger settings remain unchanged. In the opposite case
check by means of PC program all settings, especially the real time clock in logger.
Attention,
inserted battery with incorrect polarity causes logger damage!
put the lid back again and screw four screws. Be careful to have the rubber sealing properly in the
slot and tighten the screws properly to ensure the water resistance of the instrument.
connect logger to the computer and write to it the information on battery replacement (menu
Configuration/Battery replacement). This step is necessary to evaluate properly the remaining
battery capacity.
Old battery or logger itself (after its life) is necessary to liquidate ecologically!
Connection of female ELKA 3008V connector for temperature probe and binary contact
It is possible to order as an optional accessory connector for
connection of temperature probe. Signal cable should be shielded, round
cross section of minimum diameter of 3.5 mm and maximum diameter of
5 mm, maximum length of 10 m and as large as possible cross section of
cords (stranded wires). Outer diameter must be from 1 to 1.55 mm
including insulation. Connect connector to temperature signal
accordingly to the figure by means of the manual included in delivery.
Choose the most suitable plastic insert accordingly to the diameter of
stranded wires of the cable. The IP67 protection is guaranteed only if
connector is assembled correctly!
It is necessary to select and connect cable for binary inputs with
respecting the same rules as above. Connect the contact instead of the RTD probe. Due to high
impedance of binary inputs it is necessary to avoid places with higher electromagnetic interference
when installing cables from contacts (switchboards, motors, contactors, frequency converters, etc.)
