Troubleshooting
If the source of fault could not be analysed by the means of this chart, please proceed as follows:
Switch the TRZ Basic 4A/UP completely voltage free (mains and battery). Disconnect all connected lines, except from
the mains. Create line monitoring directly in the TRZ Basic 4A/UP control panel. Install the monitor diodes in the
terminals 1, 2 and 3. 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. Reestablish power supply (mains and battery).
The control panel must not signal any malfunction, green LED
OK
is shining, yellow
and red LED
displays are
dark:
• the TRZ Basic does not signal any malfunction (the fault has an external source):
Reestablish the external connections one after the other (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
motor do not present any break or twisting. All connections have to be checked. Check individual components for visible
faults.
• the TRZ Basic does signal a malfunction (the fault has an internal source):
Check the mains voltage, check the battery, check the fuses. Check the monitor diodes and the end resistors.
Maintenance
If the equipment is used in smoke heat extraction systems (short SHE), it must be checked, serviced and, if necessary,
repaired at least once per year. This is also recommended for purely ventilation systems.
Clean the equipment. Check the tightness of fixing and locking screws. Test the devices by a trial run according to the
chapter Start up procedure and trial run. The gear systems of the linear drives are maintenance-free. Defective
equipment has to be repaired only in our plant. Only original spare parts are to be used. Check regularly that the
equipment is ready for service. To this purpose we recommend a service contract with the manufacturer or another
authorized specialist.
All standard batteries provided with the SHE control panel require regular checks as part of the maintenance programme
and are to be replaced after the specified service life (4 years). Observe the legal requirements when disposing of
hazardous materials - e.g. batteries.
The operating instructions of the connected components must imperatively be observed!
Out of order
In order to put the SHE system out of order, the TRZ Basic must be disconnected from the mains and the battery fuse
has to be taken of.
