Explanation / possible source of malfunction
discharge totally battery, take off fuse F3 (battery) disconnect
emergency batteries and wait at least 2 min. Replace by
emergency batteries and connect them, replace fuse F3.
mains connection out of order
mains fuse defective
battery out of order
battery fuse defective
mains failure
mains fuse defective
no input voltage present (230 V / 50 Hz)
no battery connected
battery incorrectly connected
discharge totally battery - replace it!
battery fuse defective - replace it!
cable break feed line SHE-switch
missing or incorrect end resistor (correct value 10kOhm
cable break feed line detector
defective detector
missing or incorrect end resistor (correct value 10kOhm)
cable break feed line of pressurized gas generators
fuse defective
slide switch are in position “secured”
incorrect line termination (ER) in the SHE man. call point
(correct value 10kOhm)
shortcircuit in the triggering circuit of the SHE-man. call point or
autom.detector
the connected cores touch the TRZ Basic DG door
batteries incorrectly placed

If the source of fault could not be analysed by the means of this chart, please procede as follows:
switch the TRZ Basic DG completely voltage free (mains and battery)
disconnect all connected lines - except from the mains
create
line monitoring directly in the TRZ Basic DG control panel
install the end resistor “SHE-man. call point” in the terminals 12 and 17
install the end resistor “autom. detector” in the terminals 18 and 19
restablish power supply (mains and battery)
the control panel must
not signal any malfunction, green LED
is shining, yellow
and red LED
displays are dark.
•
(the fault has an external source)
restablish the external connections
(do not forget monitor diodes and end resistors), check after each connection, if the fault is eliminated!
check if the feed lines for
the SHE man call point, autom. detectors and electromagnetic clamps do not present any break or twisting
connections have to be
check
check individual components for visible faults.
•
(the fault has an internal source)
check the mains voltage
check the battery
check
the fuses
check the monitor diodes and the end resistors
check the slide switch.
