Operating instructions
4.8
EOS Electronic Interface - Interfaces (optional)
4.8.1
Supply-Voltage for EOS (24 VDC):
with box:
te24V and GND
without box: X3/1 and X3/2 on EOS Electronic
Interface
Output for EOS supply:
unregulated voltage: 20 - 32VDC
max. 20W continous load
short term load: 36W (1s)
4.8.2
Power Supply X2
X2/1 and X2/2 on EOS electronic interface
It is possible to connect 24VDC directly to this
input, instead of using the supplied transformer.
4.8.3
Safety circuit X4
with box:
terminal K1 and K2
without box: X4/1 and X4/2 on EOS Electronic
Interface
nominal voltage:
100 VAC … 250 VAC or
48 VDC … 200 VDC
optically isolated
4.8.4 Accumulator X5
without box: X5/1 and X5/2 on EOS Electronic
Interface
24V, 2.1Ah
Runtime: ca. 2-3 hours
Charging time: ca. 16 hours
replace latest after 3 years
If the EOS electronic interface isn´t used for a long
period of time, the battery must be disconnected in
order to avoid deep discharge of the accumulator
and thus avoid permanent damage to the accumu-
lator.
For this reason, the built-in accumulator is discon-
nected ex factory. It has to be connected before
operating the EOS Electronic Interface.
4.8.5 ENM1/ENM2
with box:
terminal ENM1 and ENM2
without box: X6/1 and X6/2 on EOS Electronic
Interface
These outputs are used by the EOS for UCM func-
tionality
4.8.6 Battery Error
The accumulator is checked periodically (~30h).
Therefore the accumulator is loaded with a resistor.
The resulting voltage drop is measured and analy-
zed. So this output can signalize a broken accumu-
lator. In this case the accumulator has to be chan-
ged. With the DIP-switches the output can be con-
figured (see chapter 4.10).
