System (AMWS) (Optional)
Description
Most TrojanUVLogic
™
models can be provided
with an Automatic Mechanical Wiping System
(AMWS). Please refer to the system
specifications as listed at the front of this manual
to see if your system is equipped with this
feature.
The AMWS uses food grade rubber wipers
contained within a Split Ring Wiper Housing,
mounted on a stainless steel Plate, placed
around each of the Quartz Sleeves. The Wiper
Housings for all Sleeves are mounted together
onto a common Wiper Assembly.
Short lamp systems (AS models) have one (1)
Wiper Assembly per UVR. Long lamp systems
(AL model) have two (2) Wiper Assemblies per
UVR to maintain full wiping coverage of the
Sleeves.
Wiping System Drive
The Wiping System is driven by an internal
Screw Drive which is directly driven by an
externally mounted Electric Motor. The Screw
Drive is installed within the UVR chamber and is
powered by an Electric Motor. The Electric
Motor is mounted on the service end of the UVR
and is protected within the End Cap. The power
for the Wiping System is brought in from the
Control Panel (CP). The power requirement
given for the CP includes operation of the wiping
system.
The Wiper Assembly is mounted to the Drive
Screw attached to a Carrying Nut that moves the
Wiper Assembly along the Drive Screw.
Wiping System Operation
The AMWS operation is controlled via the CP.
The Wiping System is set to clean at a regular
time interval.
The wiper cycle frequency (cycles one hour) in
which the Wiper Assembly operates is set by the
customer and is dependent upon the water
quality entering the chamber. The faster the
Quartz Sleeves tend to foul and reduce UV
Transmittance, the higher the cycle frequency
should be set by the customer in order to
prevent fouling.
If the Wiper Assembly encounters significant
resistance while in operation, the Gear Motor will
automatically turn OFF, protecting both the
Wiper Assembly and the Quartz Sleeves. The
display will indicate Wiper Alarm General, in the
Status field of the Operator Interface.
