Intended Use
Warning Device NVD-111
The warning device is a compact alarm system for monitoring one sensor in a
sludge tank of a car wash equipment.
The warning devices must only be installed in a suitable control cabinet or
NVO5-KV installation housing.
The warning device was designed for the monitoring of the sludge level, i. e. an
alarm if a certain limit of maximum receptacle capacity of sludge has been
reached.
Sludge Level Sensor FAU-104
The sludge level sensor FAU-104 (referred to as "sensor" in the following
sections) is a suspended sensor for monitoring sludge levels.
The sensor must always be connected to an warning device of type NVD-111.

Commissioning
Configuring the Warning Device using DIP Switches
Often, mud and dirt particles are stirred up by pump operation in the sludge
tank. These mud and dirt particles can cause a false alarm for the sludge level
sensor. Therefore, it is possible to set two possible monitoring states for the
sludge level sensor on the warning device via the setting of DIP switch 1
(reaction time of the sludge level sensor).
Switch setting ON – operating mode
• The reaction time for detection of a sludge level is 24 hours (warning device
in normal mode, green LED "SYSTEM OK" lights up). Only after the sludge
level sensor has constantly been in a sludge level for 24 hours is the alarm
status displayed via the LED "SLUDGE LEVEL ALARM" and, if applicable,
an acoustic alarm triggered and relay activated.
• The reaction time for detection of water is 1 hour (warning device in alarm
mode, red LED "SLUDGE LEVEL ALARM" lights up). Only after the sludge
3 level sensor has constantly been in water for 1 hour does the LED
"SLUDGE LEVEL ALARM" go out and the LED "SYSTEM OK" flashes.
Switch setting OFF – service/test mode
• After switching on the warning device or after switching the DIP switch from
ON to OFF, an alarm is detected immediately and the warning device
displayed. The DIP switches are located on the right of the device.
Operation
Alarm Signals
The warning device indicates an alarm status or sensor fault both visually and
acoustically. The "SLUDGE LEVEL ALARM" LED is illuminated until the system
returns to a normal status.
