Quick Start Guide September 2020
Safety information
WARNING
Hot surface
Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and
the process temperature is lowered to a safe level.
WARNING
Corrosive substance
The solution used during calibration is an acid.
Handle with care.
Follow the directions of the acid manufacturer.
Wear proper protective equipment.
Do not let the solution come in contact with skin or clothing.
If contact with skin is made, immediately rinse with clean water.
CAUTION
Application compatiblity
The wetted sensor materials may not be compatible with process composition and operating
conditions.
Application compatibility is entirely the operator's responsibility.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

1 Overview
1.1 Unpack and inspect
Procedure
1. Inspect the shipping container. If it is damaged, contact the shipper
immediately for instructions.
2. If there is no apparent damage, unpack the container. Be sure all
items shown on the packing list are present. If items are missing,
notify Emerson immediately.

1.3 Storage and maintenance
Sensors require little care or maintenance. Simple guidelines follow:
During storage, keep sensors near room temperature and capped on the
measuring end. These caps supplied from the factory are filled with a weak
pH 7 buffer in order to keep the sensor wet. Check sensors in storage semiannually to assure that the cap retains moisture; if the pH 7 buffer
evaporates, replace it with ordinary tap water.

Quick Start Guide 3
Quick Start Guide September 2020
Cleaning the pH sensor is easy. The reference usually does not require
maintenance. If a coating forms over the exposed portion of the reference,
scrape it off with a small penknife. Take care not to break the glass when
scraping the reference.
Glass pH electrodes can be cleaned in a number of ways. To remove scaling,
oils, and other stubborn coatings, soak the electrode in a five to ten percent
HCl solution for a few minutes and then rinse it under tap water. Very heavy
coatings may require more than one soaking. To clean minor coatings,
direct a stream of tap water directly onto the glass. With new sensors, wipe
the glass with a clean, soft cloth. Take care with this approach as the glass
may break when mishandled.
Oils or greases that can accumulate on the glass bulb may not be visible to
the eye. To remove these, stir the sensor in a solvent such as isopropyl
alcohol. Heavy build-up may require a number of alcohol cycles followed by
wiping with a soft cloth. You may also use a dish soap.
Run sensor cables through the conduit or protect them from the
environment; they are not weather-proof. Do not allow cables and
connectors to become wet, lay on the ground or across equipment, etc. Do
not abrade, pinch, twist, or sharply bend cables.

Procedure
1. For integral cable sensors, reference Figure 2-1-dimension B to select
appropriate mounting nozzle or pipe tee dimensions to achieve
desired insertion depth.
2. For VP sensors, reference Figure 2-2-dimension B to select
appropriate mounting nozzle or pipe tee dimensions to achieve
desired insertion depth.
3. Wrap the sensor threads (D) with PTFE tape to prevent leakage.
a) Use front facing threads for insertion installations in a pipe
tee/process nozzle.
b) Use rear facing threads for submersion installations threaded
into conduit.
4. Do not overtighten sensor into its receptacle.
5. Hand tighten the sensor, then tighten one or two turns with a
wrench to secure in place.

Procedure
1. Remove extension piece (G) from sensor sheath (J)
2. Loosen compression fitting (B) several turns and gently push onto
the sheath (L) with threads facing the blowout safety stop (A)
3. Lubricate O-rings on sensor cartridge (L) and Kynar extension (G) if
needed.
4. Slide sensor into sheath until the tip bottoms out. Cable should be
routed through the sheath a. For VP sensors (Figure 2-5), male VP
plug (B) must be fully routed through the kynar extension
5. Hand tighten extension piece clockwise, so the threads engage those
on the rear of the sensor.
6. If sensor cap is still in place, remove, and install sensor into process.
7. Reference Figure 2-6 for dimensional information on completed
assembly to assist in setting the correct depth for the sensor into
process
2.3 Wire sensor to transmitter
Procedure
1. Remove the protective covering on the white (reference) wire.
2. Wire the correct sensor leads to the main board using the lead
locations marked directly on the board.
See the diagrams below. You may use either integral cables or
Variopol cables.
NOTICE
Keep sensor and output signal wiring separate from loop power
wiring. Do not run sensor and power wiring in the same conduit or
close together in a cable tray.
NOTICE
Do not overtighten submersible sensors during installation.

3 Startup
Refer to the manual for your transmitter (Rosemount 56, 1056, 1057, 1066,
or 5081) for directions on operating the transmitter after it has been wired
to the sensor.
Procedure
1. Wire sensor(s) to the signal boards.
See Wire sensor to transmitter for wiring diagrams.
2. Once connections are secured and verified, apply power to the
transmitter.
WARNING
Risk of electrical shock
Electrical installation must be in accordance with the National
Electrical Code (ANSI/NFPA-70) and/or any other national or local
codes.
When the transmitter is initially powered up, Quick Start screens
appear.
3. Refer to the manual for your transmitter to complete the steps in the
Quick Start process.
