Dulcodes UV-Desinfektionsanlage
WARNING!
• The disinfection output of the UV system is drastically reduced in emergency mode.
• Emergency mode is not permitted in connection with applications with demanding
requirements in terms of disinfection output such as in drinking water disinfection or
comparable applications.
• Distinctly reduced output levels can be expected in applications where emergency
operation of the UV system is permitted.
• In emergency mode, a shut-off valve (if fitted) opens immediately after pressing the
START/STOP key and not after exceeding the safety threshold. There is no monitoring as
to whether the UV lamps have heated up to operating temperature and provide adequate
UV output. If necessary, the water flow should be turned off manually (manual shut-off
valve, switching off the delivery pump manually, etc.) for 5 to 10 minutes after switching
on emergency mode.
• Before enabling emergency mode in the program menu and before switching on
emergency mode, the system operator must check to ensure that danger to persons
and property by the drastically reduced system output is ruled out.
• ProMinent shall reject any warranty claims or claims for compensation in the event of
damage during emergency operation of the UV system.
A special code is required for the purpose of reprogramming the system behaviour in the event of
faults. This code can only be obtained from ProMinent on request. After entering the special
code, emergency mode can then be selected under system behaviour in the event of faults.
If emergency mode is selected in response to a fault, as before, the system will assume flow
mode in the event of a lamp failing or if the safety threshold is undershot after the clear flushing
time has elapsed. The system then assumes emergency mode by pressing the CHANGE key on
the display. The fault is therefore not confirmed with the ENTER key.
Emergency mode can also be triggered by closing the FLOW switched input.
Automatic transition to emergency mode can be achieved by bypassing the input.
The UV lamps are ignited, the shut-off valve is opened and the pump relay picks up in emergency
mode. The alarm relay (fault signalling relay), however, remains dropped out, i.e. lamp failure and
the sensor signal are no longer monitored. The signalling relay for WARNING THRESHOLD and
SAFETY THRESHOLD undershot remains dropped out.
IMPORTANT!
Intermittent flushing is not possible in systems where emergency mode has been enabled.
The programming windows for max. standstill period and intermittent flushing time are
therefore blanked out.
Since the pump relay picks up in emergency mode even with the pump control OFF, the pump
relay can be used for the purpose of signalling emergency mode in systems with the pump
control set to OFF. In systems with the pump control set to ON, emergency mode can be
identified by the fact that the pump relay is still picked up although the alarm relay has dropped
out.
4.3.21
Alarm Signalling Relay
A signalling device can be connected to the ALARM signalling relay.
The relay drops out in the event of a fault or power failure.
4.3.22
Fault Switched Input
An external fault-signalling device such as an overtemperature switch can be connected to the
FAULT switched input.
IMPORTANT!
The FAULT switched input is bypassed on delivery. If the jumper is removed without
connecting a fault signalling device, the control will assume flow mode and it will no longer
be possible to operate the UV disinfection system.
ATTENTION!
Remove the jumper when connecting a fault-signalling device otherwise no fault/
malfunction will be signalled.
