4-20mA Sensor Interface Breakout Box
Models: PRO Series, D4+, D4 Premium, E4+, F4+, G+, H+, J+, K+
Overview
The 4-20 mA UV sensor interface unit allows the UV sensor current to be accessed and monitored by an auxiliary device so that
remote monitoring can be achieved. The unit must be terminated with a resistor so that the loop current is maintained and not
broken. Connection to the loop is done by connecting the termination wires to the terminals marked + and - and securing the wires
with the brass thumb nuts.
Section 1 Safety Information
Please read this entire instruction sheet before installation. Pay attention to all danger, warning, and caution statements.
Failure to do so could result in serious personal injury or damage to the equipment.
Make sure that the protection provided by this equipment is not impaired. Do not use or install this equipment in any manner
other than that specified in the instruction sheet.
1.1 Safety Precautions
D A N G E R
Failure to follow these instructions will result in serious injury or death.
Shock Hazard - Stored Energy
Disconnect power to system before performing any maintenance or repair.
There may be more than one source of power. Only connect to a GFCI.
Protective ground
DO NOT touch with wet hands.
Pressurized Device - Impalement Hazard
NEVER perform any physical inspection, repair or maintenance on UV chamber unless UV chamber has been isolated and depressurized.
NEVER service UV lamps, lamp sleeves or associated hardware until depressurization of UV chamber has been confirmed.
DO NOT store any combustible or flammable material close to the system.

WA R N I N G
Failure to follow these instructions could result in serious injury or death.
UV Light Hazard
ALWAYS use UV protective gear, including gloves and UV safety glasses.
NEVER look directly at illuminated UV lamp, even when using protective gear.
NEVER illuminate UV lamp outside of the UV chamber.
If accidental exposure occurs, immediately cool affected area and consult physician.
Contamination Hazard
If UV lamp breaks, avoid inhalation, ingestion, or exposure to eyes and skin. Wear appropriate clothing and personal protective equipment.
NEVER use a vacuum cleaner to clean up broken UV lamps as this will scatter the mercury. Obey local regulations and guidelines for the removal
and disposal of mercury waste.
WARNING: This product can expose you to chemicals including Phthalates, which are known to the State of California to cause cancer and birth
defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
C A U T I O N
Failure to follow these instructions could result in minor or moderate injury.
Thermal Hazard
Allow UV lamps, UV chamber to cool for a minimum of 10 (ten) minutes before handling.
When there is no water flow, the water in the chamber will become hot. To prevent scalding, allow the system to cool for 10 minutes before draining
the system.
Personal Injury Hazard
UV lamps and lamp sleeves are fragile. Do not strike, bend or apply pressure, or they will break.
DO NOT handle UV lamps or lamp sleeves with bare hands. Wear rubber or latex gloves to handle previously installed UV lamps and soiled lamp
sleeves to protect against contaminants. Wear cotton gloves to handle new UV lamps and clean lamp sleeves.
Hg Exposure
The UV lamp contains mercury. If the lamp breaks, then avoid inhalation or ingestion of the debris and avoid exposure to eyes and skin. Never use
a vacuum cleaner to clean up a broken lamp as this may scatter the spilled mercury. Obey local regulations and guidelines for the removal and
disposal of mercury waste.
N O T I C E
System Protection
To protect the Controller, a UL 1449 certified (or equivalent) transient voltage surge suppressor is strongly recommended.
Avoid Injury
Read and understand this Instruction Sheet before operating and performing any maintenance on this equipment.

Section 2 Installation
Procedure:
1
Remove the UV sensor cable
(blue connector) from the
controller unit.
2
Insert the sensor interface
cable (blue connector) into
the controller where the UV
sensor was connected.
3
+
-
Plug in the UV sensor cable
into the plug in the sensor
interface unit.
4
Connect a 2 conductor Signal
cable (not supplied) to the
terminals + and - on the UV
sensor Interface unit.
Secure the wires on the
terminals with the brass
thumb nuts.
5
Monitoring
Unit
Run the signal cable to the
auxiliary monitoring device.
Notes: 1) Ensure that the
monitoring device will
terminate the loop with a low
value resistor 100-300 ohms.
This is to ensure that the loop
current for the UV sensor is
maintained in a closed loop.
2) Failure to maintain a
closed loop will result in a
sensor fault alarm on your
controller unit.
If issues arise when connecting the loop signal cables to the auxiliary
monitoring device due to interference in the electrical ground loop
circuit, it is recommended to use a 4-20mA loop powered isolator.
Note: This device is not supplied. This device should be purchased
and added as part of the auxiliary monitoring device.
