12 Maintenance switch "S4": "Maintenance functions"
"S4-1...10" are set to "off" at the factory
S4 - 1...8 unused
S4 - 9 Switch on / off red LEDs (H2...H7) on E3X101
S4 - 10 Maintenance mode. Blocks all control outputs and activates the corresponding
LED:
Module Control outputs LEDs
E3X101 Q1 ... Q8 H2 ... H5
E3L020 I/O1 ... I/O16 H1 ... H16
E3G050 K1 ... K8 H1 ... H8
E3G060 1........6 H1 ... H6
E3G070 Q1....Q7 H5... H11
z Extinguishing control module E3G080 is not included in the blocking of the S4-
10.
z Also blocks the monitoring of the 'Emergency operation circuit fire alarm'.
13 Plug-in terminals "K2": Remote transmission equipment
14 Lithium battery 3 V / 70 mAh: RAM buffering for clock, user data etc.
– data storage time: minimum 2 weeks, typical >100 days
– maintenance-free
15 Double flat cable header "ST1" (26-pin): I-Bus
16 Key "S10": System start only with battery (without mains voltage)
17 Plug-in terminals "K1": Supply for the "I-Bus" modules
18 LED indicator block "Battery charger"
yellow "Power supply fault"
green "Mains operation"
yellow "Battery fault"
H501
H502
yellow unused
Indicators vary in meaning according to application:
a) Battery operation
and symmetry moni-
toring
LED ”Power supply fault
– Input voltage > 31.0 V –> power unit malfunction
– Battery voltage > 29.5 V or < 25 V –> charger malfunction
– Charger malfunction
– Charger shut down (via software function)
– Temperature sensor open line / short circuit
– Temperature sensor measures > 55 °C
– EEPROM check sum error
LED ”Power on”
– Input voltage > 28.5 V
LED ”Battery fault
– Battery voltage < 23 V
– Asymmetry > 1.0 V or fuse F503 blown
– Possibly cell short circuit
– Open line to battery or fuse F501 / F502 blown
– Autom. test to indicate battery presence negative
– Autom. battery load test negative
b) Battery operation
without symmetry
monitoring
LED ”Power supply fault
– Input voltage > 31.0 V –> power unit malfunction
– Battery voltage > 29.5V or < 25 V –> charger malfunction
– Charger malfunction
– Charger shut down (via software function)
– Temperature sensor open line / short circuit
– Temperature sensor measures > 55 °C
– EEPROM check sum error
LED ”Power on”
– Input voltage > 28.5 V
LED ”Battery fault
– Battery voltage < 23 V
– Open line to battery or fuse F501 / F502 blown
– Autom. test to indicate battery presence negative
– Autom. battery load test negative
LED ”Power supply fault
– Input voltage > 31.0 V –> power unit malfunction
– EEPROM check sum error
c) Operation with
external voltage (in-
stead of battery)
LED ”Power on”
– Input voltage > 28.5 V
